[Elecraft] KAT500 drops out during voice peaks

[hawley, charles j jr]

No, it’s always been on manual since I got it. And it never used to do this. Nothing is changed in the shack except in using a 4:1 balun instead of a 1:1. The timing is similar.
Tomorrow I’ll reinstall that and see if it persists.
An arc outside is a thought too. I will check my open wire feed line as well.
Thanks for the replies.
