You mean active antenna phantom powering ?
On some circuit boards active antenna power are not mounted, this is haven't any part numbers., this is cirquit board elements
look HERE and HERE

If You have a questions regarding this document, ask me, don't hesitate. But figures in this doc, more informative than words

Correct me if I am wrong, but I don't believe this mod improves signal quality, if improves sound quality.

you are right, this has nothing to do with signal.
Anyone any mod fro signal improvement?

Is there anything needed for the community?

I just exchanged my Fuze for a new one due to some mechanical issues with the model I first had. I now have a clean, new Fuze. Is there anything from here that would be helpful for the community that I could extract and upload? I have no idea, which is why I'm asking. Just wanna give back a bit, many of you guys have been very helpful.
Meantime, can someone please tell me where I can find an app that does unit conversions? Weight, volume, distance, etc.? Thank you guys!

Wow! Tks~~~
Thanks, good news!
anybody try it?

Yes, tested it.
Poor GPS-reception (only 5 sats in googlemaps). Switches from HSDPA back to 3G at places, where I've had HSDPA before...
Back to 4.47.25.01.
I am gonna test it, report back in 20min.
My main reason to test it, is because with some ROM (like Tom_Topaz_2.08_R1.1_Leo_WhiteStone) I have poor GSM reception. Hope this will fix this.
edit: same poor gsm reception, but i will keep it for few days to see how it will consume battery.
Please post your test results in the RADIO thread.
Thanks.
Would be nice if you write from where you took this Radio, right?

7floor Sound Mod For MTCD

I ve discovered that the 7floor sound mod has been made to work on an RK3188 MTCD unit by @kumarai.
I ve searched all threads in this forum and it doesnt seem to be known amongst you MTCD guys (or even to have been mentioned), whereas over in the MTCB forums (the mod was developed for MTCB units) quite a few people have done it.
I thought it would be worth mentioning here.
What it does, basically is remove control of the sound processor from the MCU and give it to Android for a very worth while improvement in sound quality and more features.
It does require some soldering and there is a small difference in what has to be done to the software (see first pic) to get it to work on MTCD units. Cant say it will work on Sofia or PX5 units, but theres no reason to think it wouldnt or couldnt be made to work on them.
Here are some links :
@kumarai on youtube :

@7floor's original thread :
https://forum.xda-developers.com/an.../mtc-sound-controlling-bd37xxx-sound-t3234660
7floor's Xposed repo page (which now mentions MTCD units) :

thats very cool,
however does it get rid of the constant hiss sounds, and the noise generated when mcu is processing.

I ve got an MTCB/C unit and I never had those issues even with the MCU controlling the sound processor, so I dont know, if the sounds are caused by the MCU processing sound then maybe.
Software part?
Hello,
I'm very interested to perform this mod but I'm having couple of questions. The unit is now on my kitchen table and I have all the parts I need.
How does the software part go with MTCD unit, because we cannot install xposed framework?
For me This is the correct route(different from 7floor):
BD37 -26 SDA - R70(100ohm) - SDIN
BD37 - 25 SCL - R71(100ohm) - SCLK
I've read that older models have 1kohm resistance but I have 100ohm which should lower the interference "hiss/fuzz" sound. Sound is pretty good now but only bluetooth A2DP quality suck with iPhone and I'd hope this mod would improve it.

There are 4 different versions of MTCD units, you need to state which one you have
edit : I can see from your other post that you ahve 5.1.1, you CAN install Xposed (but you need to be rooted).
Installed xposed framework
Oh yes, my unit is running 5.1.1 Hal9k android with KSP MCU, RK3188 and 1 GB of RAM.
I managed to install the xposed framework successfully! :victory: Now I'm installing MTC sound app and after I have checked it out I will solder the wires. :fingers-crossed:
Any tips how to get those little Rs out safely, because my tweezers won't get a good hold of those?
I have Dasaita V600 model with PX5 system. I was wondering does anybody know is it possible to do a 7floor mod on this unit?

Well I have read and is only mentioned it could work but i was wondering has anybody try to open px5 unit and see are those components the same like in 3188 or similar. Because I would like to try to do that mod but would also like to know has anybody try it already on px5.

I saw that post, but honestly I didn't have time to read all posts. And majority of what I had chance to read was for px3 boards.

Well youre supposed to read the thread before asking questions. All the info you need is in both threads.

C'mon man.
Anyway I was able to perform the mod successfully, at least it seems that way. But I have not had the change to install the unit in a my car yet so I really don't know if any sound is actually coming out...
My tip for soldering. Add little extra solder to the old components before removing. That way you have little more time to warm up both ends.
Had to install the MTC sound 2.0.5. app to avoid UI error.

Does anyone have issues with Bluetooth? I tried to find more info from the original thread but didn’t find anything useful.
I have sound from radio and Spotify but Bluetooth calls won’t work. I can’t hear anything from the Bluetooth app and A2DP goes directly to calling screen.
How can I get the A2DP to work so I can stream from my phone?
Edit: No problems after all. Had to toggle gsm via android from the EQ and then calls work just fine. Then A2DP works only when using stock launcher. I find that weird.

Strange, you could try BT app that includes the A2DP function (as opposed to one that has a separate app for it) and see if that makes a difference . . . although youd have to go through all the ROMs to try and find one. What processor have you got ?
