I have saved up a few mundane questions for the Drake folks. Instead of separate emails, I will just ask them all in one:
1. The early AC-3 power supply had some sort of choke filter for the +650 volt section, right after a bridge rectifier looks like. My buddy has one of these actually. can someone explain it briefly, and tell why it was changed out (cost perhaps)? 2. In the TR-3, does anyone know why it was designed to require going back and forth from SSB to Xcw to transmit and receive CW? I got out one of my TR-3's and re-discovered this, and after looking at the manual, found it was true. Pretty inconvenient, and probably pretty hard on the switch over time. 3. When putting new diodes in an AC-3 or AC-4, is it recommended to add speed-up caps and equalizing resistors across the diodes? 4. When working across a band on TR-3's or TR-4's, I usually just peak the Rf tune, but wonder how far one should go before re-dipping again in the same band. Thanks for listening, and thanks for all the good advice over the years. 73 Mark N5KAE (a fellow Drake Transceiver hobbyist) _______________________________________________ Drakelist mailing list [email protected] http://mailman.zerobeat.net/mailman/listinfo/drakelist
