Re: [Elecraft] KPA500 Dead

Lyn, On your KAT500, do contact support about it, and if they want you to send it in, do so. Many techs are working from home, and while the time from receipt at Elecraft until it is shipped may be longer, the process still is working. Who knows when this coronavirus thing will subside and
