Take a look at Jim's (W8ZR) website for his StationPro II schematics. He
incorporates a nice simple MOSFET design to accommodate the 30L-1 keying as
well as modern keying. www.w8zr.com

Subject: [Amps] 30L1 keying
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
