Spiros, I keep a local archive of nighttime Eu and TA spectrograms, and could upload or send interesting ones any time later. If you prefer to collect captures yourself, you could use an automatic do
Hi Rik, I guess the xtal is inside the JUMA which is warming up during TXing. So it's the same problem that HF TRX-transverters have... 73, Stefan Am 09.02.2013 20:47, schrieb Rik Strobbe: Hi Spiros,
Hi Spiros, drift is about 0.5Hz on 137kHz = +/- 70Hz drift on the 20MHz xtal oscillator of the DDS VFO. One should expect better. Do you have large temperature variations? 73, Rik ON7YD - OR7T ______
Spiros Try OP32 , that level of drift is inside the max limits of OP32 , ( round 1 Hz ) You could set timer = 0 , then temperature would tend to stabilise , each 32 min cycle would be independent in
Spiros, I must admit, OP is possible with the JUMA while WSPR is not. So you could give it a try. But don't forget us poor grabber runners completely :-) (I know, i haven't been any better in the las
