Hello Dave,
thanks for the hint, also Fabian and Jeff have told me that 1 Hz shift for
DFCW might be not enough. I need to find another solution. Currently I
shift the 120 MHz main oscillator build into the DDS by varying the supply
voltage of the sealed chrystal oscillator, so 1 Hz is the maximum I can get
(actually I can vary between 0 and 1 Hz). Probably I need to build a
separate 120 Mhz oszillator with a larger variance, so that I get at least
3 or 4 Hz at 136 kHz ...
Hope Fabian, DJ1YFK (our youngest LF operator in DL!) makes it over to you,
it is surprising how good his little 40 Watt tx works. By the way: QRSS
must be a real challenge for Fabian, he normall is a HSC guy ...
