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...

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?

Thank you Stefan.
Looking for any QSO.
Stability very bad from YUMA transmitter on QRSS-60
