[Elecraft] K2 K2/100 post FD review

[Mike Harris]

Mike,

You are the only one who can determine this. Everyone else is reduced to 
guessing because they don't have access to your PSU/K2/power lead.

Simple:

Measure the PSU voltage on RX at the PUS terminals.
Measure the PSU voltage on TX set to 100W at the PSU terminals.

Compare both of these with the internal K2 voltage display.

Report the findings.

Regards,

Mike VP8NO
