Hi Bruce Thanks for clearing up the confusion that I caused. Yes, your solution of the low power out is really the way to go.
However (!!) I am resurrecting my old 70cms system for the European VHF Field Day this weekend. That was designed many many years ago to work with the then availability of 10 watt transceivers. To gut the system to interface at low power is one step to far in the time available! I guess the easy solution is just to use 28MHz at a clean 13 watts drive and accept that the display (and the logging programme) will show 28.200 rather than 432.200 !!

Hi, Roger. What's in a name? Herein lies some of the confusion. On the K3, the 100W amp is the KPA3, not KPA100 (K2 amp). As to your problem, would it not be more efficient to use the low level output available from the KXV3(a) to drive your transverter? This would eliminate the waste of all that power in the dummy load, and provide a cleaner output, as the K3 LPA board (12w amp) is not used, I believe. Good luck, Bruce, N1RX > I should have said that it is a K3 I have. > Is it possible to change the cut-in point of the KPA100 ??
