So I have a 30L1, and am trying to design a keying circuit that will allow
keying the -160V relay line with a radio whose amp-key output is a
common-emitter NPN rated to pull down a max of +100V.not trying to do qsk cw
here; I'm seriously debating keying the amp with an external relay driven
off the station +13.8 bus.if anyone has a better idea I'm all ears.73, Brian
