The HPSDR transmitter sounded FB on AM - better than your Viker CDC ... SSB sounded good as well. Probably first time I've heard an SSB transmitter with third order products > 50 dB down! Look forward to hearing it driving a BIG linear.

TNX Jay....remember the EV664 I bought at Deerfield. I decided to use it on the sdr stuff. Well you were only hearing about -40 DB last night. Not enough power supply or heatsink yet. It does look sice on the spectrum display.
