[Elecraft] KPA500 Keying Issue

[Dave's Mail]

My KPA500 will not key on 40 meters. It keys and puts out full power on all other bands. There is no asterisk showing on the KPA500 display when attempting to key and operate it on 40 meters. It's there on all other bands. VOX is on on the K3 on all bands. I just don't get any power out of the amp on 40.

Latest firmware is on both the K3 and KPA500.

Has anyone had a problem like this or have any ideas???

Tnx es 73,
