Hi,
I installed the K60XV in my K2 and while checking the output I
discovered that when I increase the power control the output follows
the control until I reach about .85 mW out then the output jumps to
2.7mW and stays there.
When I bring the control back down, the output remains at 2.7mW until
I reach about .65mW on the LCD screen.
I have checked that all components are in the correct places and that
the diodes are properly oriented and all solder joints are good.
I did a quick in-circuit check in the diodes and an out of circuit
check on Q2 - all check OK.
I checked the voltage change on the VRFDET line and it does the same
thing as the power output - it increases smoothly until the output
jumps to m2.7mW and then remains constant at a little over 3V.
Before I go any further or bother the very busy folks at Elecraft I
thought I would see if anyone on the reflector has run into the problem.
All suggestions gratefully accepted.
Thanks

ps - all upgrades have been done on the K2
