In your version of the mod, you do not have a decoupling capacitor, and the DC is still traveling inside the tuner. I haven't tried it yet and i don't have information whether it is good or bad. However, because of the high frequencies, generally it is not a good idea to mess with the tuner internals. Can you provide a better photo of the opened tuner? I haven't desoldered mine, and I want to see if I can figure out what is wrong with the layout.
10x in advance :)

Yes there is a decoupling cap. it is part of rf amp input. blocks the dc voltage. The F center conductor takes two paths, one to pin 2 and off to FB101 and another path through cap to Mosfet. The current carry capacity out to the h-h motor is improved by this mod due to the #18ga. wire. The pcb has an ultra thin trace and would be high resistance at 300ma. See qqboxmod1.jpg for the decoupling cap. it is just to the upper right of the cut foil trace.

DO NOT ATTEMPT THIS MOD UNLESS YOU REALLY KNOW WHAT YOUR DOING OR YOU WILL FOR SURE RUIN THE QQ BOX.

My thoughts on Sharp tuner problems:

1- The PCB RF choke printed in the tuner is ineffective.
2- First IF coming from LNBF is degraded by PCB choke.
3- Diesqc commands can interfere with onboard uP.
4- The several bypass caps hurt the RF and Diseqc signals.
5- The trace for the LNBF power and H-H motor is undersized.
6- If the mod is done losses and EMI will be reduced.

one more thing, after the foil cut and addition of wire and choke you must replace the top shield properly.
Most hobbyist don't have the skill to do this mod, my advice is, don't attempt it.

Here is an equivalent circuit-

I bought one of these qq box some time back. I did a lot to try to make it work (vista os). I did get it to scan one time. I sent it back for refund. If 1ADAM12 gets this thing to work and the mods needed to make it work I might give it a try. I liked the little thing and sure wish I could have made it work. Keep up the good work 1ADAM12, thanks for you efforts.

Cool avatar... is that Roby the robot?

If you order another QQ Box, check out Shippenpc on ebay, good price and honest guy. If only the factory checked to see if they worked before shipping.

Thanks,

Yes it is Roby, I used to have DR. Smith but you know just no respect. Could not trust the man. But it looks like some modes need to made in USA to fix the defects in this unit. I have the skills to do and tools, just want to make sure it will work when Its done. Let me know if you get a completed fix for this you unit and I will order another one.

Please keep up the good work I hope this unit can be made to function.
Have a great day. Eric Walker

For those of you hoping for DiSEqC 2.x support, the STV0288 DiSEqC Rx pin is unconnected in the Sharp 7395 tuner. :mad:

I haven't been back for a while. I ended up getting a DM04 instead of a QQbox since it seemed obvious the internal design was different and I was hoping it was better designed then the QQbox. Reading the recent posts, was I correct? Mine is DM04B10030364 and has the Sharp tuner of course. (I think all recent ones do?)

Also thanks for the Linux drivers. Doesn't support my box yet and not that I'm using Linu or want to at the moment but nice to have the option!

BTW in case people haven't noticed the price of the QQbox and DM04 has come down in recent months. When I bought the DM04 in June it was about US$31 all up. Now it's about US$27. :-( Qqbox was about US$26, now it's US$23.

As far as I can make out.
DM04B100 is sharp 7395
DM04B090 is sharp 0194
DM0408 is LG

The sharp 7395 has 16mm spacing between the RF connector center holes and the Sharp 0194/LG has 22mm.

I can't get hold of a sharp 0194 to add support, but I don't think they have been made for sometime.

Yeah sorry I worked out later and was meaning to clarify, found I couldn't edit my post then got distracted. Mine has the 0288 tuner (well I use 0288 drivers) which I think means 7395.

Anyway I promised some pics a long time ago. Here they are

BTW I think I remember a while back someone saying they couldn't get it to work with AltDVB. I did. But you need the Star Edition III (well I don't know if you need 3 but it is/was the latest).

When you get that version you should notice there are 2 BDA drivers, Dev_Bda2Driver and Dev_BdaDriver. Dev_Bdadriver is by ALTX and is in the older AltDVB. Dev_Bda2Driver is by DioDato. Do not use the Bdadriver/ALTX as it doesn't work can't find any channels. Dev_Bda2Driver works fine for me. Even after the channels are tuned/found if you switch to BdaDriver they don't work. There's signal strength but no quality (at least I think that's what the L and Q stand for). Never worked out what the deal was.

Now if only I could get it working with MediaPortal...

I have a DM04B090 (DM04B09050101) which has a LG tuner. IMHO the LG tuner is way better than the sharp tuner :rolleyes:

Hmm... Looks like it is just a rolling serial number then.

I have found that the Sharp tuner is more sensitive than the LG tuner especially in a rain storm with a mini dish. The LG required a line amplifier.

Does anyone have any tips for reducing the problem of the qqbox/dm04+ not resetting? I never really used mine much so didn't have much experience. And I'm lending mine to a friend now but in my testing of their set up, I'm a bit alarmed at how many times I have a problem which I think is caused by the not resetting bug. There's one confounding factor which is the physical setup wasn't very stable so I kept pulling out the power supply which is plugged in to an adapter as they don't have ones with NZ/Aus plugs. However there's at least one instance where I'm reasonably sure this didn't happen but I seemed to have problems. I usually unplug both then replug power and USB but so far haven't made it work again without restarting.

I have a DM04+ with the Sharp tuner. I'm using MediaPortal and the drivers from the LME site on XP SP3. I think I'm going to disable EIT guide and use XMLTV so the device isn't jumping around muxes so much. Any other suggestions? Perhaps Linux would have been better but setting that up wouldn't have been easy and it's a bit late now anyway.

Thankfully no blue screens although in some ways they may be better.

Only the USB needs be unplugged to reset the device. The power adapter should be powered up all the time.

The power for the LME2510 or LME2510C chip comes only from the USB port.

Sounds like the firmware is failing to download properly. The device should automatically disconnect then reconnect in warm state.

I found, that there was lots of timing issues with this from system to system.

Almost everyone here has been helpful.....except the guy that favours the STB. He's probably right.;)

This device will never work reliably in Windows until the LME people fix the driver. There maybe a hardware problem in the LME2510 that cannot be overcome. Dissapointing that they don't support the LME2510. For someone here to make a fix would require reverse enginnering the chip and that is a total waste of time.

My experience is that if you unplug the USB port whilst running media software you get blue screen.

I think you also experienced the driver/hardware doesn't properly reset and so can no longer tune and you need to hard reset the device problem? You mentioned you wrote a detailed bug report to LME.

I agree it's unfortunately they are unwilling to provide decent support although sadly not surprised.

Has anyone bought the DVB-S2 version of the QQBOX (or DM04) from china?

It contains a LME2510C and a Sharp BS2F7VZ7700 tuner. The tuner itself has the same case work as the Sharp 7395.

The Chinese sellers on Ebay appear to be confusing in that they show it along side the TBS model.:eek:

I have been using this as a second Sat input for an XP system with DVBViewer with relatively few problems using the driver installer on page 12 of this forum.

I recently decided to upgrade my system to Windows 7, and started on a spare (small) hard drive. When I installed the driver I got a BSOD at the end of the installation process. I restarted the machine and it did not recognise the device because it had no drivers for it. However, when I looked at the properties it then showed me what device drivers it had for the card! I then pressed a button (can't recall which) and it installed the drivers. Success.

Then I decided that I needed a bigger hard driver for the "proper" upgrade. I then completely failed to do a complete clone of the original drive (and wiped it in the process - don't ask!), so had to start from scratch. Same BSOD when I installed the driver, same unknown device drivers yet will list the drivers, but this time when I try to enable/upgrade the drivers now I get a BSOD, and it still does not see the device. Anyone recognise these symptoms and have a fix??

That driver doesnt support any switches unfortunately. In DVBdream it misses on 1/4 channel changes as well. I've given up hope for a driver to fix the problems, too bad because the hardware seems decent and it is so cheap.

there are 3 things we didnot check
1- as i see in SCH and Silkscreen the power input printed is DC 9V
2- the attached power adapter with qq box package is 8V output
3- the power input printed on qqbox input is 7.5V
may be this effect on qqbox stable
how can the power adapter which come with qq box package is 1 ampere (size is small) and give stable output!

The QQBOX does two things with the incoming supply, one step down to 3.3v, two step up to 13 or 18v. The supply can be anywhere between 6 and 9v and be stable.

The power supply is a switch mode type, therefore small adequate supply.

LME has sent me the Schematic for this product.

Good reason for it not to work, NO EEPROM!

It uses a 24C02 which is available form www.mouser.com (http://www.mouser.com) but without the programmer and firmware, this is the end of project.

Here are the documents for QQ Box USB DVB-S Receiver.

I have found out that the 24C02 is not required and is internal with LME2510C.

Fitting the chip may cause the firmware to malfunction. Strange that the schematic should show it, because it is still readable and writeable without it.

Possible thought, perhaps that have pinched a ROM area of the chips firmware loader and emulated the 24c02.

The firmware is loaded into RAM area inside the LME2510/C, the EEPROM stores tuning data, tuner id, and possible mac address.

1- if i need to use the QQBOX as sattelite finder what is the best program using for that and very sensitive for signal ?

2- as you told before the power input needed for QQBOX is 6V to 9V. how can i use the USB of my PC(laptop) instead of external power adapter ? because the USB gives 5V only ?

Dev_Bda2Driver.cfg

you can find them on path

Hello Dear Adam , Box Spy and all :cool:


using lnb loop ot will enable us to use our diseqc with QQBOX

http://freesatadvice.co.uk/wp-content/uploads/2009/04/bush_bfsat01hd_rear_388x70.jpg


Example: on my Dish i have 4 LNB fixed with Diseqc ports as bellow:


1- NileSAT
2- HotBird
3- ArabSat
4- Amos


as known if we connect the cable which come from Diseq to QQBOX ,LNB on Port1 (Nilesat) only will work
i made a new method enable us to make remaining ports 2,3,4 works


1- we will need to Receiver then plug in the main cable

(which come from Diseqc)


2- make new cable and fix one in your QQ BOX (normal) and the other in your receiver LNB out


3- turn on your receiver and setup your LNB as you fixed (of my example 1Nile,2Hot,3Arab,4Amos)


4- from your remote choose sat list and choose Nilesat-->ok then turn off the receiver from remote(dont unplug power cable)


5- from your programs make scan for channels or transponder (i used ALTDVB as it works well) note: don't choose any diseqc mode, All=none


6- if you want to watch HotBird channels (LNB2) just turn on receiver and from sat list choose HOTBIRD then turn receiver off


7- make in step 5


8- if need to scan or see channels on Arabsat go from step 6


this way made me to watch all LNBs fixed on my Diseqc
you cannot watch two sattelites on same time
if the reciever power is on, you can only watch one transponder which using in reciever (you can change from remote) so u can watch same channels


we can say this method is temporary till LME make fix for that in new driver :confused:
and they should test on
AltDVB
ProgDVB
Dream DVB

It is a good idea Alaa but wouldnt it just be cheaper and easier to buy 4 QQbox?
Then you can access all 4 birds simultaneously.

At that point though, I would just recommend buying a tuner with proper diseqc drivers. Who is not dissapointed with QQbox, I sure am. But for $30 shipped it was a nice price.

The problem is that L101 and L103 are both standard ferrite cores, energy is transferred from L101 to L103 through the case.

L103 was originally a toroidal type which is less prone to magnetic pick up. While changing L101 to a shielded type does help horizontal pick up, it does not eliminate energy through the case work.

I changed L103 back to the toroidal type and have experienced no problems at all.

Incidentally, they have stop selling the QQBOX on Ebay in the UK no doubly due to returned units, due to Sky mini dishes LNB more sensitive to the noise.

Hi all, long time reader, first time poster, please be gentle.

I bought one of these devices from dealextreme from here: $28.40 - DVB-S Digital TV HDTV USB 2.0 Box/Tuner with Remote Controller - Hardware Parts (http://www.dealextreme.com/details.dx/sku.28533)

It was in black with an EU plug.

I am based in London, England and trying to scan for various channels using a variety of software but only a handful of the FTA channels are coming up.

My setup is as follows: sky minidish - which has 4 lnbs coming out of it. 2 to living room, 2 to study.
In living room, hooked up one of the lnbs (tried both at various stages) to the LNB in on the qq-box. (What is the loop used for?)
I dont have any subscribtion card software etc, so really looking for all the FTA channels I would normally see on Sky or Freesat.
It's hooked up to Windows 7 x64 with the updated x64 drivers as found in this forum.

That's where the trouble begins. I have tried progdvb, dvbviewer,, blaze, windows media center, but I cant see quite a few channels, and some which are meant to be free/unlocked/unecrypted show up as encrypted.
Channels not showing up include: BBC1, BBC2, BBC HD, ITV HD and more
Channels showing up but are "locked": ITV2, C4 and more
Channels showing up and working: Channel S, BBC Parliament, CNN, Sky News, some other random ones.

Also I have had various BSOD with media center/progdvb etc when it appears to have frozen/locked and I have no option but to take out the usb.

I am choosing Astra 28.2E (Astra 2A/2B/2D/ Eurobird1) settings for the various tv tuner software. I am a little confused what the lnb setting should be - none/minidsq/2/4 osscilate. But I have tried each and every setting.

After the scan the above channels listed as not showing up are just that - not showing up. I have even tried to do a single frequency scan to see if it shows up, but nothing. The same scan on sky receiver shows up the expected channel.

Does anyone have a foolproof method of getting the following channels to work: BBC HD, ITV HD, BBC1, BBC2, E4, More4 etc... I would be soooo grateful, as otherwise have to return this as not working :(.

Kasam

Thanks for the reply - do you have any other information?
Is this device ultimately incompatible with UK Freesat/FTA?
Or is it an issue with SOME of the qqboxes that have a hardware issue?
Is there anywhere to buy this device with some sort of guarantee or is it a case of giving up using it in UK?

It just a case of poor PCB design, and wrong component. Otherwise modified QQBoxes work fine.

The DM04 (the black plastic boxes) have exactly the same components and have no problems in the UK.

Hi Canalsat and welcome to the forum.

Let me see if I understand correctly:
You are using a dual output LNB, and DVBDream works when you use the loop out from the receiver, but not if you connect the QQ Box directly to the LNB?
If that is correct, do you have LNB power on in DVBDream? (because it sounds like you aren’t getting power to the LNB when hooked directly from the QQ Box to the LNB)
Also, are there any switches, splitters or other devices connected between the QQ Box and the LNB? (forgive my asking, but have to be sure)

Oh, and you may have gotten a response earlier if you had started your own thread.

Sounds like the noisy LNB voltage problem, and stuck in high band. Using another receivers pass through usually removes the noise.

In Windows LNB voltage is on by default, so at least some channels should be present.

Check the satellite you are scanning has high band channels (>11.7GHz).

All the frequencies from Nilesat 101 at 7.0°W are high band, check that the LNB is an universal type and not a special type for the receiver (pay tv).

Nilesat 101 at 7.0°W - LyngSat (http://www.lyngsat.com/nile101.html)

I think the signal may just be too low and is amplified by the receiver.

I don't know why i must choose on or off for 22KHz in normal structure(from dish to qq box) for taking the signal of some frequencies but normaly i must choose (controlled by lof-sw )like i do when i use the loop out their i have signal

their i want to tell you that finally i find the source of my problem
it was in the cover ,this cover of aliminium minimise the signal when it become neir the tuner
so i must now beyond the cover for taking an accepted signal in prog and alt but in dvb dream it's still very weak
have you any idea about how can i cut this contact between the cover & the tuner if i want return the qq box inside the cover
also i want to ask you about ravcho structure (http://www.satelliteguys.us/attachment.php?attachmentid=56224&d=1285781556 )
is it perfect for me to increase the signal?
best regards

Hi Everyone !
I m new in ur forum
** My English Is Too BAD so So I apologize ,, i use sometimes GOOGLE TR **

I have a BLACK QQ BOX [ Like in the pic ]
First , I install the driver , & I install PROG DVB
& i do everything but the signal level is 80% or more & Signal QUALITY is 3% or 4% !

i read some problems like me
posted in this thread , & ADAM says : " You must apply the electrical insulating tape to either the PCB or the USB end plate. Without this the tuner will "FLY". "

is this the solution ??

If Yes , Where I should apply the electical insulating tape
And THANKS !

Just a quick warning, make sure you use the right drivers (for the right tuner)!

This may seem obvious but I couldn't remember what tuner I had and incorrectly thought it was the Sharp 0194. I also thought it would have a different hardware ID (VID or whatever) so wouldn't install with my USB device by default so when it installed I thought it was the right one. I then spent an hour or two trying to work out why it wasn't working with MediaPortal (resetting it, trying various setting etc) before moving to DVB Viewer which also didn't work before deciding to check these forums only to find out I had the 0288 (as I mentioned before). So I then installed the correct drivers and got it working in both programs easily ;-)

In retrospect I shouldn't be surprised they either gave the same PID & VID or put the PID & VID for the 0288 in the 0194 driver INF despite it not working....

Hey Nil

With linux driver of tvboxspy (http://www.satelliteguys.us/member.php?u=156822) my problem with signal in QQ BOX is finally resolved in ubuntu 11.04
kaffeine & me tv shows all channels with a great signal quality 98% reverse of windows player who shows 40 % of signal quality
my dream still to run qq box in windows player with signal quality like ubuntu without changing my dish to one biggest cause my dish is less than 1 metre.
special thank's to tvboxspy (http://www.satelliteguys.us/member.php?u=156822) for her important driver of linux.

for kaffeine you have to choose the satellite from main menu and wait for a long time it work fine with me
the remote control is off for me too i think tvboxspy can resoulve this and give us the name of this remote their we can search here Index of /remotes (http://lirc.sourceforge.net/remotes/) and copy the keys to remote.conf
i try now to make qq box on with vdr because the sound stop for me

Linux media remotes have under gone significant changes recently and many user applications are broken. If you are using less than kernel 2.6.31 it is possibly completely broken.

By default lirc is loaded when the rc_core module is loaded. However, many applications do not support the capture keys.

keys 0-9 should work in Kaffeine and power, volume -/+ buttons the desktop.

Test this, open terminal and press the number keys.

There are three known types of remotes with the QQBOX/DM04, it is possible there are more.

Hi,
i followed what you said here and downloaded the drivers from https://sites.google.com/site/tvboxspy/installing-linux-v4l-driver the latest v4l drivers, and i did the build command and make install etc... all work fine qqbox got detected but when i fire my program it keep saying tuning, it kicks in for 2 seconds then go tuning,

any hint?

and i got a tb5922 and installed the driver from there website after following there build instruction but not my QQ box does not work,

how can i make both work, as each time i build driver for one it overwrites the other.


what can i do for the long tuning message , it stays tuning all the time its not locking.

Thanks

Hi all!

I'm trying to get VDR + XBMC working, but I don't have lucky.

I have installed in debian, arch linux and now in lasted ubuntu and in all i have the same problem. I have cuts in the image and sound, seems to be the signal low, or a short buffer, I don't know. In other sofware like Kaffeine or me-tv, witch the same driver the device work successful, It's strange!

Can somebody help me? I know that CanalSAT have this combo working successful, but I don't know if him has the same problem.

Thanks and cheers all!!

I recently purchased a QQ Box to use with freesat. However, using a universal usb it was locked on to high band due to the L101 problem. The answer was to carefully remove L101 by gently prizing it with a small screwdriver while de-soldering each leg alternately and then glueing the inductor upside down on the other side of the board near the lnb socket. After re-connecting L101 with two fine wires the box works well. This way you don't have to buy the Murata Inductor. The problem was that placing the two inductors side by side created a transformer which coupled a permanent signal from the switched mode power supply to the tuner.
I'm using XP with the Sharp driver supplied with the box and Next PVR.

I have tried VDR, the problem is that it keeps trying to change pids while the streamer is running. I am not sure what it is doing, but it gets to the sixth pid entry and keeps swaping for pids on other channels.

Unfortunately, the firmware does not support this.

The only soultion is to turn the pid filter off with

dvb-usb-lmedm04 pid=1

You can put this in /etc/modules (or /etc/modules.preload) file, so to always boot with the pid filter off.

It appears that VDR examines other channels on the transponder with last PID entry.

Changing PID stalls the streamer, then the PID filter starts it again.

Again, the only way to overcome this is to turn the PID filter off.

His Linux driver will do Diseqc 1.0 / 2.0 and 1.2 to drive an H-H motor. It already works with Diseqc switches using factory driver.

Any driver for Win XP / Win 7 to make diseqc work ?
