I love working on boat anchors. Tubes are a thing of beauty. (My OTL HiFi audio power amp has 22 tubes that glow most lovingly in the dark.) But most people running AM today are using modern rigs. These are rigs that already run SSB. Let a little carrier leak through but continue to suppress the unneeded sideband and you can get all that without throwing away 88% of the power. Oh, and you gain 3dB at the receive end by cutting the noise-admittance bandwidth in half. Use SAM to synchronize with the carrier for perfect exalted-carrier demodulation. That does beg the question -- will the SAM decoder lock onto a single-sideband reduced-carrier signal? If not, it would be cool to implement that. Give the broadcaster wannabes a HiFi mode that doesn't need fancy tuning but doesn't take up massive bandwidth to do it. Sorry. I think too much. -- Brian Lloyd, WB6RQN/J79BPL 3191 Western Dr. Cameron Park, CA 95682 [email protected] +1.767.617.1365 (Dominica) +1.931.492.6776 (USA) (+1.931.4.WB6RQN) _______________________________________________ Flexedge mailing list [email protected] http://mail.flex-radio.biz/mailman/listinfo/flexedge_flex-radio.biz This is the FlexRadio Systems e-mail Reflector called FlexEdge.
