Pete, Can you explain why you feel the Elecraft teransverter are 'far better' then the DEMI units? Just curious as they both claim a .8dB NF, +17dBm conversion gain, etc. I'm also concerned with the lack of a heat sink on the PA's on the Electrafts. I've run the DEMI's for hours on end (calling CQ during contest) and they have barely been warm.
