CW Cable For Hybrid Transceivers Using Solid State Relay
Well, the title says it all. The cable is built around the NEC’s PS7205B-1A SSR, which is with GaAs LED input and optically-coupled dual MOSFET output. The schematic is simple. The only caution is that the C2 — the capacitor at KEYING side, must be rated at 100V. This is because in TS-830S for example,…
