Hello All, My XV144 is up and running with my K2 as the driver. Using the wide 10m mod and a few hours with spectrogram I have peaked the bandpass response at the ends of the 144-146 segment: for satellites (my main interest) and weak signal.
The biggest problem I had during construction was mounting the PA module. The heat spreader was fairly flat but the module had a curve that gave a 1.6mm gap in the centre. No thermal insulator was going to fill that gap. In the end I spent a few quiet hours carefully rubbing the module on a "flat smooth" file (with everything I could get earthed for static protection). The module backplate is just plated copper. Got the gap down so I couldn't see any light between the module and the heat spreader. The module survived and warms up the bottom of the case quite well. 73 de David VK5DG _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
