I used a signal generator with lots of buffering in the early days of 136kHz. Although to was fine for CW it produced worm shaped traces on QRSS. I think it was caused by RF feedback. I am not using my crystal mixer exciter (which has been replaced with a DDS unit) which you are welcome to. This is fine for normal QRSS but has a +/- 2Hz long term drift, which made it unsuitable for transatlantic stuff Regards, Peter, G3LDO e-mail Web
