[Elecraft] setting KPA 100 page 48 problem

[Christophe aufacf]

hello Don, hello everyone,

this morning I tested the K2 on my own.

the consumption (ampere) of K2 gave me part of the solution

the K2 alone in transmission consumes 0.5 amp on 40M then on the other
2 amp bands with a setting at 5Watts

so I have no broadcast on 40M only, we can hear the relays switch ...

after I admit being a bit lost to know where to start

I will review the soldering of relays K1, K12, K14 in case ...

could you give me advice since you know the K2 very well

Thanks in advance Don
