Thanks Harry. I just thought it was strange that it changed right where the crystal boundaries are. Still not sure I don't have a bum 2m module. I haven't looked at the actual signal to see how it looks.

I use a different transverter for 2m but the situation is the same using the K3. RF output appears to drop quickly above 30-MHz when in the transverter mode though receive seems functional to 32-MHz enabling receiving the entire 4-MHz 2meter band. At 146.52 (K3=30.52 MHz) my 50w 2m transverter will only output 8w because drive drops to minimum. This is too low for me to operate in the FM repeater sub-band of 2m as all but one repeater are > 65 miles from me. Typically takes 25w to have a full-quieted signal thru these repeaters. From what I understood in communication with Elecraft this is a hardware limitation with no fix. That is the bad news. The good news is the KX3 suffers no power drop off over the whole 2meter band with the new 2M module. 3w drives my "little" RFS 2-23 amp to 30w which is adequate for my FM needs. If I need more power the 30w drives my RFC 2-317 to 150w, and if that is not enough 55w out of the RFC 2-317 will drive my 8877 to 1400w. Of course I do not use the 8877 with repeaters else they "melt down" :-) I usually run my K3 with the 8877 via the 50w transverter for ms/eme. 73, Ed - KL7UW ----------------------- Subject: [Elecraft] K144XV Message-ID: <[email protected]> Content-Type: text/plain; charset=utf-8 Finally got around to installing this in my K3. There seems to be a large difference in output power vs input power when transitioning across the 146.000 threshold. ? Below 146, 0.5mW drive gives 6 out. Above 146 it only gives 2 out. And swr does not change. Ideas?
