Comment on Nexmon SDR: Using the WiFi Chip on a Raspberry Pi 3B+ as a TX Capable SDR by Languagemaniac_

Haha I would love to do that mod, I’ll wait for someone to do it first. The idea thrills me

Comment on Nexmon SDR: Using the WiFi Chip on a Raspberry Pi 3B+ as a TX Capable SDR by AD5NL

I did a bit more poking around on Google and I see that the Raspberry Pi 3b+ does not have the pads for a u.fl connector.

However it does use a Proant PCB resonant cavity antenna similar to the RPi Zero Wireless. And there have been folks who have attached coax or antenna connectors to that model. (Looking at photos there are some differences but it looks like there is basically a trace that would be RF hot).I think it should be possible to cut the trace to the PCB antenna and attach coax there. Which can then be filtered, amplified and otherwise mucked about with RF components.

Of course this would violate the warranty and the Raspberry Pi Foundation would disavow all knowledge (cue Mission:Impossible theme).

Not supported. Use upconverter.

Direct sampling isn’t mentioned, so I’m assuming it’s not supported?

You should probably supply it 9v then. But do you know what the freq range of the amplifier is?

maybe voltage. I am only feeding it 6V. Reviews say best perf is at 9v.

All in all , I now have about $175 invested in this :o :shock: :roll:

Should have just bought a nice Sangean or Tecsun radio at that price :D

But the tinker in me would not be happy with that I guess :lol:

Waiting for my connectors and other misc wires to come from Amazon. They lost my package :cry:

Your LNA could be out of range. check to see if any higher frequency signals are amplified., like FM broadcast.

Dose this has support for Tx? Will hackrf or LimeSDR be supported?
