Hi Mikael,
Thanks for your time.? I think the xo speed was a good hint.? I'm doing a mock-up using the Adafruit SI5351 breakout board.? The board has a 25MHz TXCO, but I noticed that the HABalloon code was set for 27 MHz.? So I made that correction.? Also, someone mentioned that my signal seemed off target frequency, so I looked through the code and found WSPR_FREQ set for 14000000 MHZ, so I adjusted that to be 14095600.? Now I get a signal that seems to be in the filter frequency path.? I believe it may be WSPR, but not sure as I can't seem to find a good Waterfall diagram of a WSPR signal, online.
Still not decoding in WSJTX, however.? Looking at the waterfall, it appears to me that I may be overdriving the receiver, particularly considering the receiver and SI5351 are directly connnected, no antennas.? I'm going to try an attenuator and see what happens.
In the mean time, here are some updated pics of waterfalls.? Thanks for your time.
TY,
Jeff
