Pete, Nice work getting everything working. I was experimenting the Cypress clock chip and got that working with software as a master clock source for Tayloe type detectors. I got sidetracked with another microcontroller project and I had to put the SDR stuff on the back burner.
I'm interested in the transmit add-on and was wondering if your design could go up to 5W output instead of 1W. Also, how would it integrate into your existing receiver? Would you have a new PCB with both xmt and rcv? Thanks, Tony --- In [email protected], "ni9n" <peg...@...> wrote: > > Hi, all!
