Looking at it more closely, pigtail will not work, the pin will stick right into display flex cable. No big deal, we just going to use different connector. You still need pigtail, so you can cut the cable of off it. In video description I will include everything you need to buy for dual antenna setup, and describe why you need it. So everything is in video description -- parts, tools, consumables, supplies, etc. We are going to do another video on making the hole for 2nd antenna, but for now, in this video you have everything you need to get it going yourself. 👍
Salut à toi et merci pour ces vidéos très explicites. J’attends aussi avec impatience la version de la carte avec ampli. Hâte de voir tes nouvelles vidéos avec montage de la nouvelle carte et la double antenne. Bonne continuation. 73’s👍
The part named R25 is a transistor and with a second antenna you should solder the coax to the input of this transistor and the braid to the ground area below the display.
Like this? imgbb.com/s57C3ns I replace R25 with BF550AR low noise transistor. I don't use the amplifier though, it makes things worse I think. I hook up after the amplifer, the bottom IPEX connector.
@@codernov I used an Elecraft rf generator with 3 levels -33dBm, -73dBm, S9, and -107dBm, about S1. Without the Transistor only stations with S9 and more were audible.
I understand you getting better signal from a generator with an amplifier, daaa. But how about real world tests? Here is my real world test. Amplifier = nothing is heard. No amplifier = we have reception. ua-cam.com/users/shortsaH7C9a3aVYY
I would love to see the 2.5 Full install I know you think you will like to do full 3.0 but most of us now have the 2.5 and looking for full video.. Regards N3WER
Why do you insist on so much heat from your iron on such fragile components? You had it correct the first seconds, but you insisted on going at it for some 15 seconds. It makes me quiver watching you. But your information is very good, and I follow this info.
I wouldn't care with iron temperature, for as long as solder on ground goes molten. I do care about hot air temperature though, because with that, things can get brown and crusty. Iron temperature is more to save my tips, usually 350, sometimes 390. My tips are WQ, they are hard to get and they don't make cheap copies like T2 tips.
I just received the version with the preamp today and was concerned as it was a bit bent up. Thanks for bringing attention to that audio issue as I’ll inspect the FPC closely now. Cheers, lots of good rework techniques in your videos. Very practical 👍
Today is celebration for me, v2 with preamp finally cleared customs and is on its way to me! Look, once you install it, there is huston we have a problem. CEC firmware is crap. It is based on egzumer, which is not bad I guess, but spectrum was cut to make way for SSB, so it's basic stuff. No hope with CEC. So you have a choice to make. I made mine. I went with Reborn. Reborn is work in progress, it has a lot of things and supports Si4732, but it does not have CTSS, so you can not open repeater with it. But hopefully it will be upgraded soon. I'm buying second radio, with Si4732 I will run Reborn, and the other radio will have fully functional Punktracker firmware.
@@codernov I’ve been messing around with Open GD-77, now after seeing the band scanner now I’m wondering if the Quansheng custom firmwares are based on that? 🤔 STM32 based.

You are like the Bob Ross (famous American painting artist) of SMT soldering! A soothing ASMR experience watching you work.

Great video, thank you! I hope to do this mod sometime in the future.
Another awesome video Alex!! I like the detailed instruction, very easy to follow along. Quick question... Why add two antennas?
So that you leave the stock choke in place and don't mess with it, that way your Si4732 SDR mod don't mess with your stock receiver and transmitter.

@@codernov Found it makes a big difference using the Transistor. However, with a really big antenna it could already be too much.
@@heinerrambold8889 What was your testing procedure?

I also got the board without the choke and capacitor. Can you write me the capacitor and choke values so I can buy separately.
Check out the latest video, it has those values.
Please tell me the value of the capacitor that needs to be replaced
100nF
