T90 dish and bandstacked LNB's?

A multi-part question:

Is their a practical way to get a T-90 Toroidal to work with Dish Pro (band stacked) or Dish Pro Plus (Double Stacked?) compatible receivers?
(i.e. Is there an external bandstacker available that is compatible? Or does one have to try using modified Dish bandstacking LNBFs, which I think are not reversed like toroid specific LNBFs?).

I suspect one could use two DP34s or two DP44s in parallel to multi-switch in both polarities of the dual LNBs but this would require dual cable runs to each Dish dual tuner DVR. I want my cake and to eat it too. Can this be made to work?

Might you not actually need a 6x4 multiswitch and a DP44 to handle the feeds from all the LNBFs and more still support more than 2 Dual Tuner Receivers?

I gathered somewhere around 50 of the DishPro LNBFs (dual outputs) that were designed for one orbital location. Only one had an aluminum stepped plate and it looked much older than the rest. I never spent any time on it because it was very noisy. The stepped plate looks like it would require fairly delicate surgery to convert to reversed polarity.

See the attached photo for a comparison of these two types. The one on the left has the aluminum stepped plate while the one on the right has a plastic dielectric plate. Note the stepped plate LNBF is much thicker at the base, but inside the plastic shell this may not be apparent. However on mine there are two little screws mounting each F-connector for the stepped plate version, while the dielectric plate unit uses only a nut on the connector itself. As I have only one of the stepped plate models, I can't say whether these characteristics are definitive. However all my dielectric units are alike and are certainly easy to modify.

All the LNB's my distributor shipped me are of the stepped plate kind (the left ones in your picture). Been trying to find a DishPro PN: 151019-NS but find a distributor up here stocking them. (ideas?)

The case on mine is quite wide on the neck, basically wouldn't work on the T90's LNB holders without removing them from the case. Do the one ones on the right in your picture which you modify have a thinner neck or do you have to mount them outside their cases also?

Almost all of my DP circular LNBFs were surplus from Superdish assemblies I bought on eBay to get bandstacked FSS LNBs (11.7-12.2 GHz) for my T90s. All had dielectric plates inside. I reversed a few for our DN subscription and only recently found a use for the rest - I published a thread on adapting their feeds to the FSS LNBs. I would have offered them, but I now only have a few left. There are usually plenty of cheap DP LNBFs on eBay, and perhaps you can get a seller to make sure they send the right type.

I tossed the cases as they're mostly decorative, That leaves a neck that is much smaller than the T90 LNBF holders. I wrapped a thin strip of rubber around the necks of the feeds to get a tight fit.

No Modifiable LNBF is Distribution in Pacific Northwest

I've checking in with several distributors in the Pacific Northwest and none have the style shown in the right side of the picture. One pointed to another F-Connector difference. The blue dialectric being Dish Networks current standard to ID high frequency parts 2.2 GHz. The white dialectric indicates to them that this is an early DishPro LNBF. So I'm now going to look farther afield for the units you have suggested.
Any comments are appreciated.

Just wanting to clarify something. You have converted polarities of DishPro LNBF's (DBS type Circular Polarization but w/Band Stacking) not just the DishPro FSS LNBF's (FSS type with Linear Polarization but w/Band Stacking for picking up 105 or 121)???

I specifically need to flip the polarity of 3 DishPro LNBF's for use in the T90 to pickup 110, 119 & 129. This is for a Dish Network subscription not FSS Free-To-Air off Linear Birds, and no need for 118.75 at present.

Yes, I've flipped the polarizations for the circular (12.2-12.7 GHz) DishPro LNBFs. The only reason I brought up the old Superdish LNBs (105 and 121) is that a lot of these show up on eBay and they often have 1-2 of the modifiable DishPro LNBfs thrown in. That's where I got most of mine.

I've gone farther and farther afield, a number of US distributors and dealers, Sadoun. Most recognize the part externally but say they have not had the old style for quite a while. It appears that the dielectric depolarizers are the older design and the new ones are all based on the cast wedge type. Ebay has only one DishPro currently for sale but it has only one LNBF and no easy way to verify its type.

I suspect Dish changed the designs as a cost savings exercise in manufacture even if their is a slight loss in gain.

The Sonora stackers unfortunately stack hi at 1550 to 2050 MHz not Dish's 1650-2150 MHz so these won't work properly with a DPP 44. I've talked with their chief engineer but creating an alternative stacker is not a high priority for them right now.

I thought I could turn the wedge DishPro LNBF 180 degrees and I think the physics of depolarization would work but likely to obstruct signal between the primary and secondary reflectors.

Any other ideas?

Song Name Game Part 3!

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....

Laptop Shutting Off When On Battery?

Lately my eight year old Dell laptop has been shutting off even when I have a full battery. I have had to keep it plugged up all the time to keep this from happening. Any idea what is causing this? I replaced the battery about three years ago.

A recalibration might be needed. Even if it shows full, the individual cells may have become unbalaced. And the BMS chip in the battery reports false information to the pc.
Try this. Start it up in the bios/uefi and leave it there until the battery dies and it shuts off.
It might just keep running longer than in Windows. Or run for a short while and shut off.
If it's the first case. Probably just needs a balancing. If the latter, the pack might just be dead.
Not throwing stones but perhaps just a cheaply constructed battery with substandard cells. Could be.

Patience. Keep restarting it in bios/uefi until it won't fire up anymore.
Then plug the charger in and let it complete a full charge. And see what happens. If it's better.
Do the same thing one more time. Run it until it dies dead-dead. Then just let it charge, pc shut off.
When charged, it might be better. It might not be.

There are bench jigs that read the actual BMS and override it to let a tech manually monitor and charge the separate packs. They can also reset any "time bombs" in it that cause an otherwise good pack to show bad.
Maybe Santa will be good to me some year.

You might just need a new battery. Maybe the PC power management chip is going. A Dell common thing.
Leaving a laptop plugged in with a full battery is known to reduce the life. Asus for one recommends that you don't leave the charger plugged in all of the time even when shut down. And setting Windows to charge the battery to 85% instead of 100% increases life.
That's all I got.

Starlink Router question

I set up a music server for my brother a few years ago. It's basically a small headless computer but it needs to have a DHCP IP address reserved for it in the router settings. This was easy to do in his DSL router. He's switching to Starlink now and I was wondering if these setting are easily accessible in the Starlink router. I'm pretty sure he will be getting the latest V5 router.

If you can't get into the router to reserve an IP address just don't use DHCP on the device that needs connected and assign it to a specific IP address in the network settings.

They are not. Your best bet is to set up a third-party router, attached to the Starlink for your server, that you can get into, like a Linksys, etc

The Starlink V5 Install Kit I just got comes with the Mini Router. It is pretty limited in what it can do. For example, it can provide only one IP subnet at a time, no Guest Network, but it does support the pass-thru to a third-party Router. You can also split the Wi-Fi into separate 5 GHz & 2.4 GHz SSIDs to help some IoT devices that don't support 5 GHz bands to work.

The larger Starlink Router that still comes with the V4 Kit does support a Guest Network with separate IPv4 Subnet, but it's $120 from Starlink. And it still won't do DHCP Reservations.

If you can restrict the DHCP address space to assign addresses to one end of the subnet (i.e. x.x.x.50+), you can manually assign the IP address on pretty much any operating system. This is a default behavior on several popular routers. As the Router Mini only supports 235 devices, I expect that's already done.

Another option is to use a router that supports PoE to power the antenna. This article discusses that option (under PoE Power heading):

Now that I've had the v5 kit with the Mini Router, it's not as bad as I first thought. Yes, no DHCP reservations, but you can set up multiple SSIDs that have separate IPv4 subnets, and like the big brother, you can select from 192.168.x.0/24 or 10.x.0.0/16 (where "x" is 1-4).

You can also split a subnet and have different SSIDs for the 5 GHz and 2.4 GHz channels to handle some IoT devices. I haven't discovered what subnet the 2nd NIC on the router assigns, I'm guessing it's the first subnet.

At least 64 dead in Spanish passenger train collision

Terrible tragedy. You would think that they would have safe guards in place that would prevent something like this from happening. I guess if you are going to ride in a passenger train it might be best to get a car near the rear.
