Is it possible to go with 20khz from one channel of the amp and 25khz from the other channel to cover a wider range of mics? Unclear if the signal generator could handle this, but if you had two of them, could you feed each frequency to a different audio channel and amplify both at once?

Thank you for putting together these great videos. I am having some problems getting this working. My main issue is with URH. I do not see any signals. I've tried different Antenna's, I went through all the possible settings, I've changed everything. Adding and removing a low noise amplifier. But it must be.... that URH on my Windows 11 is not working properly. Because when I close the software, and open up SDR#, I can see all the signals on their respective frequencies.. my vehicle FOB (315Mhz), my weatherstation (433.92 Mhz) and my garage door opener at 314.6 MHz. Do you have any suggestions on how to get URH to be able to see these same signals?
