Where did you get the idea that the KX3 2M module output 1mw? Wayne
has repeatedly stated they expect something between 3 to 5w
output. I know nothing about the Flex6700 (does it run with 1mw
output?). Most of the RF modules used in radios require something
like 20mw (+13 dBm)
Oh Really? Thats fantastic! I could have sworn I asked at Dayton and was
told it was XVTR level output. Perhaps Wayne or Eric can tell us for sure.
It would help planning!

There was a post some months ago to gauge interest in a 0dBm output module, but

I was hoping that we would truly have a two RX K3-- each with its own

That 5 volts at KPA100 U4 pin 11 comes from the base K2 - Control Board
U6 pin 24 (and the pullup resistor pins 3 and 4 of RP7).
I suspect CB U6 pin 24 may be shorted.
Since you have 2 K2s, you might try swapping the firmware between them
and see if the problem follows the firmware.
It looks like D36 and D37 on the SWR Bridge on the K3 RF Board are no longer

Are they Surface Mount? If so, can they be changed to regular diodes
What are the parameters of these diodes?
Can I still operate the rig?
