Ever since getting the Hopper3 over a year ago, I've put up with a periodic loss of connection to the internet. So this past weekend I did some troubleshooting and found out some interesting facts, at least for my setup.

I have a Hopper3 with a hardwired ethernet connection to my router and 1 Joey with a MoCA connection to the Hopper3.

The symptoms are: approximately 1 out of every 3 or 4 days, I find my Hopper with no internet connection. The Settings / Internet screen shows its not connected to my router nor internet.

The reason it's not connected is because the Hopper isn't successful in getting a valid address from my router / DHCP Server. So the Hopper is falling back to an APIPA address. (APIPA is an obscure standard for LAN devices to connect when there's no DHCP server. An address in the range 169.254.*.* is generated by the device). For whatever reason, the Hopper gives up on the DHCP server and uses this APIPA address which places the Hopper in its own little world with nobody on the LAN to talk to except the Joey.

I found that I can simulate this 3 or 4 day cycle by doing a "Reset Network". Every 3rd or 4th Reset, the Hopper decides to use an APIPA address. Sometimes it stays in this state for a couple of resets, but overall it fails to get a real DHCP address around 30% of the time.

I believe that when my Hopper does it's automatic "Daily Reset", it is cycling through this same pattern. When I'm off on a trip and try to use Dish Anywhere to access my home setup and it fails because my Hopper isn't connected, it will reconnect automagically in the next day or two.

Hopper Fix:
My Ethernet cable was plugged into the Upper ethernet port. I changed it to the lower port, and now every "Reset Network" command results in a valid DHCP-assigned IP address and a valid router / internet connection. (I did about 20 in a row).

The lower Ethernet port has a logical (Client) name of Hopper3-ETH0; the upper port is Hopper3-ETH1.

Are these ports supposed to be interchangable, and why are there two of them - maybe for use as a pass-thru for a second device in the area which needs a LAN connection? I don't think this is a hardware problem with my upper Ethernet port. The pattern is too predictable. I think it has something to do with the lower port having a lower logical Client name of -ETH0 than the upper -ETH1. Perhaps the firmware first tries to establish a connection in the sequence of the Client name interfaces, so when the first port it tries isn't the one being used, something times out or sets an error condition by mistake and it gums up the works for the valid port.

Joey Problem:
Although this fixed the APIPA problem for my Hopper, not so for the Joey. Every other time I did a "Reset Network" for the Joey, it generated a APIPA address. Worse yet, when it didn't use an APIPA address, it would hang on to an old DHCP address previously assigned by the DHCP server, even when the router / server had been reset and that was no longer it's assigned address!

I could eventually "force" the Joey's valid DHCP-assigned address through the Hopper and on to the Joey with a number of resets of both boxes, power-downs, cable unplugs etc. but these boxes should be robust and self-configuring!

Final Solution:
I set up fixed IP addresses for the devices. It turns out there are four MAC addresses in my setup:
Hopper3-br
Hopper3-ETH0 (lower port)
Hopper3-ETH1 (upper port which I'm no longer using)
Joey_MoCA
I defined the three that I'm using in my router's setup, and after a few "Reset Network"s on both the Hopper and Joey, unplugging and plugging network cables, both the Hopper and Joey consistently come back to their assigned fixed IP LAN addresses.

For my setup, it took both actions to fix the problem:
- Avoiding use of the Hopper's top Ethernet port
- Assigning fixed IP addresses

Meanwhile through all of these router resets, the other dozen connected devices (wireless and wired) in my home were perfectly happy having an IP address assigned to them by my DHCP server and running with it.
:coco

BTW, I thought I read in these forums that there was a "hidden" dialog / screen on the Hopper3 setup whereby you could assign a fixed IP address on the Hopper side. The fixed addresses I've assigned were done on the router side with the corresponding MAC addresses pointing to the Hopper's devices, which seems to be working OK.

I had a very similar issue with my H3 and a Joey2. The problem was solved in my case by taking them off a secondary vlan and placing them back on the main vlan. I had chosen to place them on a separate vlan because of the problems with the hacking of IoT equipment and placing Dish on a vlan that cannot connect to other vlans can help prevent attacks on other equipment (PCs, servers, etc.) if an attack occurs. That being said, Dish equipment is probably more safeguarded than many other IoT devices because there is no open port to the outside for threats to enter. From what I understand, the H3 contacts Dish and DishAnywhere on a device out in the world contacts Dish which connects it to the H3. Still, I would like to isolate the Dish equipment. I also want to add my TV and sound bar and a couuple more devices to the isolated vlan at some point. Haven't done that yet because I have to be able to google cast to them. I have read that it can be done (avahi, iptables, etc.), but haven't tried it yet.

Don't know if it was a Dish firmware upgrade that caused it because the problem did not happen at a time right after a new firmware upgrade from what I can tell. I had it that way for probably around 2 and it worked great. Having the Dish equipment on the same vlan has been working for about 3 weeks, but I want it back like it was. Need to get working on that.

Using static dhcp addresses was something I was going to try. I have been using eth1 and briefly thought about using the the other ethernet port so I will try all of those.

Your information is very helpful. Thanks.

I have never had any Internet issues using either Hopper upper or lower Ethernet ports connected to my router. I use the DHCP Reservations in my router for my Hoppers and Joeys. I think it is easier than using static IP method.
T
Like charlesrshell, also use the address reservation feature of my router to define the IP addresses that are assigned to my devices. That has worked well with my Hopper.

I should have been clearer. My plan is to reserve dhcp IPs on the router for the Dish equipment. I called it static, but should have used a term like static DHCP (address reservation).

It would be interesting to see that hidden menu with info for DNS that Hipkat mentioned.
J
Now that I understand the difference between the two, it turns out I mispoke. I'm also using DHCP Reservations in my router.

(Static IP is when you use the device, in this case the Hopper3, to set the IP address).

Thank you for the clarification!

Sometimes a thread gets so many posts in it that is can cause issues for the server so that why today we introduce The Song Name Game Part 3!

So let the game continue!

The last song was added by Bobby who posted...

One Meat Ball - Andrews Sisters

CONTINUE ON AND HAVE FUN! WELCOME HOME TO SATELLITEGUYS.US!

Here are the original rules for the game as posted by WebbyDude back in 2006. http://www.satelliteguys.us/threads/68645-Song-Name-Game

Just name a song title and the band who performed it. The next person does the same thing, but needs to list a song title or band name which includes a word from the previous entry. Pick songs from any genre.

Example:

Long Live Rock and Roll -- Rainbow

Rainbow in the Dark -- Dio

Another example:

Ride the Lightning -- Metallica

Lightning Strikes -- Ozzy Osbourne


Get it?


An additional note: we all know that song titles, sometimes, use profane words. Because this is a family friendly website it is advised that you clean up that title up a bit. This is accomplished by using something like sh!t instead of the real word. Thanks....

I know HipKat said that they were working on conversions but we got the official news yesterday right from Dish that starting next month all DMA's will be on the western arc, and all customers will be assigned to that. That's gonna mean a lot of customers around here aren't gonna get Dish unless there are exceptions. Too many mountains and trees.

Howdy folks long time no write.

Issue(s): Horizontal transponders (esp. Weigel mux) breakup/mosaic/sputtering audio, JTV less so (but received perfectly up until a month or so ago.
Vertical is fine (Daystar). Up until recently couldn't even get any signal on Weigel Mux but JTV was perfect.

What I did to improve things: A slight westward move improved reception but only slightly (approx 72 on the micro HD, sorry no dB to post). I removed the 3-way C-Band splitter and used a 2-way to get a 1-2 db signal gain ( the power port goes to the Startrak - the micro HD doesn't have enough juice ! (1st clue) even after swapping the switching power supply it came with with a heftier linear 12 V supply (less RFI too !).
I have had issues with the uHD before signal breaking up that a reboot would clear up (clue #2 = dying tuner?) - FYI, I reinforced the IF input and removed all flux from the pcb completely with a Flux Removal Pen (MG Chemicals Cat No. 4140-P) which definitely makes a huge difference.

I went outside and pushed and pulled reflector slightly and no improvement. Pole (actually tower in yard - the neighbours love me..NOT) is plumb, checked with carpenters level. Dish was last peaked in 2017 or so, after overhauling 24" Von Weise, new Acme, fresh grease, etc. Focal length, f/d ratio etc meticulously adjusted. One panel has a tear so planning to repair that this weekend when my cousin comes over ( to help me out (old guy here) forecast calls for sunshine.

What has changed: My utility company has installed new high tension line poles (one smack dab in the middle of 101°W target! But they put it in last year and reception (of JTV (HOR) at least) was fine, BUT when they came out to transfer the wires over this year from the old (sawed in half) pole that's about when the troubles started (coincidence?), but again Daystar (VER) was fine. I always had this pole in the light of sight of 101° before with no issues. (fyi my zenith sat 74° is unobstucted, but can't test)

In the meantime Weigel mux is trying to break in MOSTLY in LATE at night (less cell usage?) (audio not video except for a frame here or there) so don't know what has changed with this mux which suddenly "woke up". I have never had to fuss with dish moves on this satellite ( the slightest move +/- motor clicks loses lock, wheres normally on C-band I can go significantly wider east or west and still have a strong signal ( have these gone "spot beam" or narrower somehow and what is the slight difference in Az listed on Lyngsat to 100.9° affect things ( isn't that the declination i.e. requiring a tweak of declination?).

Long story short (too late, ha), if I had another DVB-S2 box to try and / or a newer more stable PLL lnb ( I have been meaning to upgrade many a time but never got arround to it) I could determine if it's my antiquated receiving equipment, or my dish/feed alignment ( doubtful as it tracks everything from 55 °W to 133 ° W nicely.) or the dreaded 5G! (BUT only on HOR and not VER?).
I read another post where the OP (with his smaller 7.5 footer) played around with the illumination to peak desired transponder and reduce qrm on interfering/ stronger xpndrs (even on 103° W). So will play with that too - and cut away the RG-6 a and pull up a fresh section with new PPC and coax Seal. Open the throat cap see if any cobwebs are there and check servo operation (also changed in last maintence 10 years ago).

Finally, this will probably be the last chance I get to play with the BUD from the looks of it (providers leaving, auctioning off rest of spectrum imminent above 4.0 Ghz, and to keep the peace with neighbours so it would be nice to have that mux back for the long, cold and dark winters to comfort this old man before I call it quits and buy a VHF/UHF/FM Yagi and get MeTV, H&I from my Vermont local stations (checked at a friends today and they come in nicely - except ABC) .
Only one guy in town (Montreal) I may be able to get a receiver or PLL lnb from to try (RPS Sat) so hopefully with elimnate that as a possible culprit. Be nice to pick up a cheap or used PLL lnb to try w/o 5G BPF (money is tight )

Like others I couldn't care less about "tv" (well maybe just a liitle or a lot) it's the challenge that excites me , I can get MeTV other ways OTA (no pirate crap).

So what do you guys (and gals) think ?. p.s. I don't have a spectrum analyzer and there are def/ cell towers nearby (half a Km or so away).
Oh and time permitting will hammer out dings too and wire damaged mesh on one section for an extra dB or two. Hesitate to touch Declination, Elevation and pole mount but will play around with those a little too... Why is this mux for finicky suddenly ?(8psk, 5/6 fec, beamwidthetc.. man wish they went back to VER I think everthing would be fine! For the engineers out here does 5G QRM affect one poliarization (HOR) more than another (VER)? I understand the strong interference swamps out the input mixer/local oscilator in the hapless old C-band lnb (I think it at time affect KU too esp. LPB on 101°W KU - incidentally thos were weak or "gone' but are back almost at the time MeTV improved..hmm Terrestrial interference?

Any thoughts or suggestions ( cheap or free solutions please) greatly appreciated. Cheers.

p.p.s. Micro HD can't display Decades and Toons but records them fine so I can watch on another box/media player (Ali chip set issue). Another reason to upgrade.

Anybody interested in a nice C/KU system free ? (for next Spring/Summer 2027)

To me it looks like all of the intelligent things to diagnose the problem 'on the cheap' are being done.
I have my own thoughts of lnbf's using an external filter between the feed and coax. It would be cool to see what Brian could add.
Do his units have the filter before the actual LNA chip in the circuit? In other words, signal is focused at the lnbf throat. The probes for h & v polarity send the signal to.......filtering......then to the lna IC......
Or probes, lna, then filtering. Makes sense to trap the bad stuff before amplification to me.

On the cheap sometimes leaves questions. Enosat and El Bandido both use dvb-s pci cards and TBS USB receivers.
With those, and software. Signal analysis becomes sort of easy. Or tapping into your coax with a dc pass splitter, decoupling capacitor, and using a spectrum analyzer. Tuning across the LO band. Finding signal spikes. Digging deep.

Still making my decision on a (most probably) TBS PCIe tuner card. But I have tapped into my coax with my ancient but quite impressive HP spectrum analyzer and tinysa.
I don't have 5G interference so far that I know of. But have my suspects because I'm only able to snag signal from 131W in the winter when the leaves drop. But out of curiosity do scan it in the fall. And seem to be getting a signal that 'shouldn't' be there and a scan shows no channels. Far as I got.

An idea pops up to rig up an LNBF on a stick. Along with the tinysa and power supply and do some rogue signal searches. War Driving, of sorts. But. I wouldn't think that a chinabox, firmware based receiver would be of much help.
From what I see scanning across the frequency band. 5G cell transmission is always on and is very wide spectrum.
Whether anyone is actually using talking, texting, watching stupid human tricks on YouTube Makes no difference. The RF is there. So why would a C Band setup come and go? And what if you dumped the corotor and went modern voltage controlled polarity?

Another thought. Since you've learned the optimal position to place the scalar to illuminate out to the dish rim. And peaked the feed. There's most of a roll of aluminum flashing out in my garage that would most definitely wrap around my dish perimeter. That and a bag of large binder clips from the office supply. wally world. Ideas?

I did some more investigating and found I got the MeTV mux in the early hours, until about 6am then the pixelating starts. Gets worse until around 8am its totally gone. I suspect my local cell tower is ramping up traffic as the morning goes on. My Titanium feed does a super job and most everything is clear that wasn't before but this mux is aggravating! I seem to just be over the signal threshold to work until the 5G total overwhelms my system. I'm using an old 9 foot spun aluminum dish and was wondering if I went to a 12 ft dish this would solve the problem? I know bigger is better in most satellite dish related signal problems. If this is true I will be searching for a bigger dish. I like your idea of flashing put around the dish perimeter. I have some I need to dig out and try before I start ripping out my dish. Anybody have any ideas if the bigger dish would do better? Any help would be appreciated!

8 1/2 Foot mesh here with the c140 lnbf and a verizon 5g tower nearby. Got no issue with the Metv transponder. Are you sure you have the lnbf setup correct? When I set my c140 up I noticed it was about 1/4 to 1/2 inch pushed in closer to the dish, sticking out of the scaler ring than my old lnbf was. Thought I may have trouble with that but my signal readings are higher than they had ever been.

Thanks for the info. I'll do a detailed feed alignment this weekend. I have to be on a ladder to tweak this 101w satellite with the MeTV mux. Luckily I've got a V8 Finder so I'll put that to use. Funny, I got the MeTV mux fine this Friday morning. Jewelry TV was completely garbled though. I'm wondering if I'm having 2 degree spacing problems more than the cell tower affecting me. Seems strange some days I'm fine and others MeTV is completely destroyed. In the old days I could just move the dish to 99w and see what's there adjacent to MeTV. Maybe if I optimize my feed I can eliminate my problem either way. I have a 9 foot spun aluminum dish that may not have the best two degree isolation. Some of these were crudely made with a poor parabolic shape. I'll keep you posted and thanks to all for the advice!
arlo
Just some rambling here. Be safe on that ladder.
Took me about 20 seconds looking at a YouTube video showing the V8 Finder in use. A spectrum analyzer display.
Well, Cool! And it can power an lnbf stand alone. More cooler.
Well there's your 5g interference wonderment solution. IF you had a spare C band lnbf. Put it on a stick and go "wardriving". If 5g towers are blowing out signals strong enough to cause interference in your dish. Well.....
And off-axis, not in the same direction as the dish is pointed? Don't exactly know.

Take a drive around and look at towers with microwave dishes bolted to them. You'll see that a large share of them do have a perimeter shield. Further diving into the likes of Andrews show shields as an optional add-on to do just what you think they should do. Block adjacent interference. Probably a good idea when multiple units are on the same, or adjacent towers. Ya' think?

Some not-so-many years ago when I dove into this whole dish antenna thing. I replaced the c/ku band corotor feed with a Titanium C2-W. Being a good boy. Assuming that the original scalar was in the proper position from day one back in the 80's. I followed instructions and stuck the unit in the hole and bolted it down at the stamped marking as per instructions. I got my first signal finally with the Zgemma H7. I was thinking "that's it?". Signal sucked.
Then I looked at how the corotor feed was located looking at the bolt marks on the tube.
It was like focusing a telescope or camera. In the end. I was getting pretty good signals. That was in the dead of winter. And I hate the cold.

A buttonhook feed support. Give a margin of adjustability versus perimeter arm scalar supports.
And a lot of reading and experimenting showed that although the scalar was probably where it should be. Isn't anymore. The focal length / fd ratio calculations probably are right. If you have a perfect parabolic dish.
Mine ain't. And its old. Most probably not a perfect parabola since it was. As well as the polar mount. Fabricated locally.
I spoke to the old guy who installed all of them here back in the heyday. Started installing Prodelin dishes.
Everyone was watching HBO and Playboy. At 3-5 grand a pop.
He told me that him and his sons made a concrete form. Finished with a plaster top coat. And started spraying resin and chopped fiberglass. Then a metal flame sprayer like is used to build up crankshafts and stuff. Finished with several more layers of 'glass. The rest. Polar mount, cast iron pole mount. Contracted locally.
That's the story. I took that old beast and if you've seen Pootie Tang. I juvenated it and then rejuvenated it.

I think that one thing to remember is that in an lnbf. All of the satellite signal amping is done in the low noise amplifier section. What signal is blown out to the coax is done in the intermediate frequency amplifier section.
So what comes in the waveguide is what it is.
I've used several receivers. Different Enigma2 images on the same receiver show different signal levels. It's a software thing. Signal calibration and display. Don't forget that. One image might not give a signal lock on a weak transponder. Fire up another? Look at the TNAP images. An option to display signal below lock.
The only real way to tell the absolute signal level you get in the house is to use a certified spectrum analyzer/service monitor.

BTW. I'm on MeTV right now. Book 'em Danno. Purposefully aimed off-axis just above the threshold of pixelation.
Only thing I see is that the sun came and the sun went. That's where I saw break up for a half hour or so.

Well summing it up in one word...success! I spent about 2 hours tweaking the feed. Found I was almost 2 inches too far from the actual focal length. Plus adjusting the skew just a hair made a big difference. I measured 3 points around the dish from the edge to the outside of the scalar ring. One side measured 51 inches and the other 53, Adjusting the button hook feed I was able to get it 52 inches all the way around the dish perimeter to the scalar. I had my doubts this would fix anything but when I turned on the satellite finder I had all the channels in the MeTV mux coming in clear! No more fading away different times of the day and night. Plus the Jewelry channels are all solid also. I'm just wondering...did this just give me more signal to overcome the interference or did properly aligning the feed effectively "blocked out" the 5G interference? Sort of wondering about sidelobes in the old parabolic antenna manuals of the 80s. Just happy to have things working correctly now. Thanks to all who helped especially to Arlo who spent a lot of time commenting to me. Best regards!

Do NOT mess with it anymore just "trying to get it a tiny bit better" than you just got it... I've been through that HELL more times then I'd want to admit.

Very cool there Brown's. My intentions are good. Sometimes tact....not so much.
I'm glad you could read through the nebula of gunk.
If I can dig through my pictures directory you might pick-up a few things I've done to and made to get as perfect alignment as possible. Your journey shows how a bit of common sense and experimentation while using known guides as a starting point (at least). The phone book just isn't full of big dish service providers like way way back.

To help. A true parabola will converge all incident rays. Light, RF. At one single point. You kind of answered your question. Two inches too close/far from the convergence point (focus) degrades signal strength. If you ever get a chance to examine a telescope. The eyepiece is on a rack. You can adjust the position of the eyepiece distance from the objective. Depending on the eyepiece. The sharpest focus is only at one finely adjusted distance.
Make sense?
And for a telescope made with mirrors. The ultimate eyepiece aim. Imagining a tiny spot right in the center of the glass lens. Will be aimed exactly at the center of the mirror. A small mirror, prism, adjustment screws assists in attaining that perfect place where a star way way back in time shows as a perfect spot. Not an ellipse, etc.
Yeah.

Who knows about the 5g thing? Did your tweaks optimize where the receiver finally got enough usable DVB signal to lock onto them and reject 5g? The crowded room full of drunks thing?

Edit:
Yeah that tiny little bit can drive you nuts.The best and only way is to find a weak transponder on a sat that doesn't "swamp" signal levels. With a matching opposite polarity having close to the same signal level.
There will be a lot of tweaking with an extended arm and......thick cotton gloves. Your body, extremities, close to the lnbf will effect signals. Then just when you think you got it. In your case. Climb down the ladder and get out of the way to see what becomes.
I got obsessed and was out there in 10 degree winter on a step ladder on clear nights.
Tweaking elevation, azimuth, declination. Unbolted actuator gearbox and vice grips. Trying to get the best of the best tracking. Adding those porch rail stainless steel turnbuckles and catv messenger wire from the rim to the scalar to bring 'er back into kilter did wonders. Don't be me. Watch MeTV!

Interesting article about the work being done to develope an ATSC 3 converter box. Yes it does mention affordable.

It's dead, they just don't know it yet. They killed it by forcing DRM on it, and that TOTALLY botched implementing it.

There is absolutely NO compelling reason for anybody to switch to ATSC3.0. They only want it as a total and complete money grab.
Mister B
What bothers me is the total waste of broadcasting spectrum in this very crowded market. It has been almost three years now since KFOX converted their broadcast tower to ATSC 3.0 and moved all of their channels to other towers causing noticeable degradation of the picture quality.
I have a Sony TV with 3.0 capabilities but still use the 1.0 version of locals due to the fact that one or all of the 3.0 channels are often missing or unwatchable. In this city of 800K I doubt that more than a few hundred even know about ATSC 3.0.
The only thing that could motivate me to be interested in 3.0 would be if all of the minor networks (diginets) could be in at least 720P rather than blurry ultra-compressed 480i.
Three years is long enough to waste one of the few available RF frequencies in the area for this trial.
It is time to either move on with this experiment or call it quits.

Love this guy's channel. Looks like Walmart has thrown in the towel when it comes to conventional car batteries.

I bought a new AGM battery from Walmart about a year ago, it is already needing replacing. I thought about just buying a regular battery but from what I've read, that might not be a smart move. Might check my Forscan program and see if I can change the battery type from AGM.

When you need a battery, you need a battery.

If you can wait, new technologies are on the not-too-distant horizon.

You're probably doing something wrong if you're only getting a year out of an AGM battery. Heat and infrequent charging both significantly reduce lifetime.

Huh? How can I be doing something wrong.....I took out the original battery, that was 6 yrs old and put in a new one.....kinda hard to screw that up. I figure it was just a bad battery....it happens.


The biggest takeaway I got from this video was the Walmart batteries only had something like 85% of battery life left even though they were brand NEW. The ones from O'Reilly all tested 100% of life left.

And the Walmart ones mostly had very little warranty.

My last AGM (using now) I got from O Rielly's, its the Super Start ... I got the Platnium, they had several to choose from.

The days of the 84-month warranty appear long gone, regardless of brand or where you acquired it. Warranties tend to be shorter, with much greater dependence on quick prorating.

The big problem for lead-acid batteries (whether flooded or AGM) is that the US no longer produces lead (the last smelter closed in 2013) and must import it.

Recycling covers a good chunk of the need (~70%), but it isn't free.

I've always got regular OEM Ford Motorcraft batteries from the dealership and have never really had an issue. On my old Lincoln Aviator (the SUV from the early 00s, not the CUV of today), I had some phantom drain and went though a few batteries, but that was an anomaly and with the standard warranty I got free replacements. Taking the Aviator out of the picture, I've bought two batteries in my 24 years of driving. One battery replacement in my Mountaineer, one in my Navigator. But I probably would have had another one had I kept it around longer. Didn't have the Bronco long enough, and so far still on the factory battery for my Expedition.

I run more than the average bear. Dash cam, two radar detectors (yes, I'm aware that can be problematic when using simultaneously), laser jammers and a police scanner. I'm in Buffalo, 90 degree summers and 0 degree winters. Once in a while in the dead of winter I'll get an alert from the Ford app saying remote features have been disabled to conserve battery, but it starts right up.

But do you have a license plate mounted on your car? lol
EarDemon
Yes, but with smokey covers. I realize they are not a countermeasure for photos or photo radar, but it helps obscure from the average persons eyeballs. Plus with the way licensee plates peel around here, it keeps them protected from the elements.

When I went to a countermeasure meetup over the summer, one of the guys who's planning on doing a cannonball had a plate flipper. While I play fast and loose (pun intended) with these idiotic traffic laws, a plate flipper is something I wouldn't dare use. Although having one in the front to flip to no license plate when traveling though states that don't require one is tempting. Am I really going to get pulled over in Kentucky for having no front NY license plate? This way it cuts down on reflective surfaces and might be helpful with laser avoidance and gives the jammers a better chance to react especially on a larger vehicle. Although LEO is typically trained to hit headlights with their LIDAR.

My OTA is not working anymore. This started after the latest update. I have the OTA dongle with a OTA antenna that I've been using for years. My hopper does not recognize the dongle anymore and when I go to the OTA setting, it has a screen that says to plug a dongle into the USB. I tried unplugging and plugging back, in the same usb port and other ports. The Hopper does not recognize it. Anyone have same issue?

Installed an off-air antenna a couple days ago for a customer who had just cancelled his Dish service. He had a dual off-air adapter and gave it to me. Cool. I'll keep it on the truck....might come in handy. Got to admit I don't watch anything as far as live tv goes anymore. Even if we have severe weather, our local channels will have a live feed on Youtube.

In other news, it was announced that the software fix for the two tin cans and a string will not be forthcoming. A hardware fix is required. However, that fix will let you receive stations from a gazillion miles away.

Truck roll charges may apply. Two year commitment required.

Hi all. If you were using a single tuner USB OTA adapter that is no longer working, please PM me. Thanks. :)

I have the dual tuner OTA adapter currently connected, but I have 2 of the single tuner OTA adapters that I can quickly connect - neither is seen by my H3.

Got the dual tuner OTA adapter, was able to set it up and get back my OTA channels. Thanks to everyone and extra thanks to the DISH reps in this forum!
