looks like from the spectrum analyzer evaluations of the latest, updated code

only LoRa leakage, no mixed signal, no LO leakage can observed...

revert the mhz to hz patch, this is where the math breaks, I have it working correctly once i removed those changes in my fork

Just tried your Code @thex1le , there is a missing bracket in line 388, but even after fixing that, the mixer doesen't seem to work. I used a DC 3.05 and my SDR isn't showing anything on 1.29ghz when i enter a mixer frequency of 1110mhz on startup of the Chat app.

The master branch shows the Signal allways on 2.4ghz because of the mixer issue :)

Interesting, I had it tuned to different channels with that change. What port are you using? on the board? You need to use the LNB port if recall, not the direct. Direct doesn't go through the mixer. The RTL.com documentation is wrong.

Thanks for the fast reply, i am using the only Port that is on the 3.05 :)
I can see that the Signal at 2.4ghz is gone with your version (or at least very weak) so it seems to activate the mixer route in some way.

Just Playing with them around right now, also have a 3.03 listening to the EU Beam right now. I think i will give the 3.03 a try tomorrow on armbian.

The master Branch Chat works with the 3.05, but it is stuck at 2.4ghz or whatever i can set the SX1280 Chip to (RX_FREQUENCY variable), what is only +/- 100mhz or so.

I used your version (after the bracket fix) on one of my DC 3.05 and wasn't able to find the Signal on my SDR. Maybe i will try tomorrow if the chat works with your version between both DC 3.05s.

Interesting, Yeah I have a version 3.03 and have two ports. Your likely picking up bleeds over on the board if you still see any 2.4ghz, the board is not shielded particularly well. What're your plans for the board? and I take it that you're saying its working now for you?

If you want i can push my little fix to your repo, just need permission for that :)

Or i can send you the file if you wnat, otherwise it really is only a single Bracket in line 388, i think you can fix it by yourself very fast as well.

UPDATE: If you fix the Bracket error it seems to work. The Signal after the mixer is just very weak so i didn't see it on my sdr that easily. merry Christmas :P

Yeah ill have to go back and look at the bracket thing, yeah changing RX-FREQ doesn't actually do anything because the lora chip can only do 2.4ghz. Its the mixer that matters. SO long as you set the mixer in hz you should be able to find it with your SDR, that's how I tested it. If you want to submit a patch for the bracket ill be happy to roll it in. Happy someone else is getting use out of this. Cheers!

Great, just made my commit with the little fix. A bit new to GIT but it worked :)

Done, https://github.com/thex1le/Dreamcatcher-Packet-Tester/invitations
