Don I've checked the bias voltages in TEST mode, both QRP and QRP, and they're correct for all bands. So the fault is clearly not a logic one associated with U1. So... the possibilities, I think, are
a) T/R circuit, but I don't know why that should be band-specific b) LPFs, but QRP TX and RX is unaffected c) ALC The ALC could kill the QRO outputs on 40 - 10m, but an explanation of how it does it above 11W would be much appreciated. 73 Bob MM0RKT _______________________________________________ Elecraft mailing list Post to: Elecraft@mailman.qth.net You must be a subscriber to post to the list.
