Jack, you have very nice images on your webpage. Very nice...and impressive.

I'm sure you will be adding to this forum considering your background in education and ham radio. I look forward to your input.

Hi Bob:

I just joined the group a few days ago and look forward to working on it. I've ordered a µSDR kit, but hope to modify it for a TFT display and a Teensy T4 processor. I'm not very adept at EE stuff, but not too bad on the firmware. I'm looking forward to it.

That is indeed an interesting concept. I wonder if it would pass an FCC certification, though. A lowpass filter is needed, no doubt, and I don't see one. Nor AGC, etc., etc. But it is indeed interesting.

If you're interested in a truly amazing use of an Arduino in an SDR check out the uSDX transceiver
