Q about mic wiring
I see that for my Peiker dynamic mic, the red wire typically connects to
the MIC pin of the radio, and the yellow wire (with or without the braided shield) typically connects to the MIC GND of the radio. In a typical installation, do people actually run a coax type wire with a shielded braid (or maybe a foil shield) from the radio connector out to the mic (where the center conductor would be MIC and the braided shield MIC GND), or do people just run two insulated wires side-by-side? Although there's quite a bit of mic/radio info available in the searchable Google archive of r.a.s, I didn't see anything on this topic. Ken |

Ken I am not familiar with that particular microphone but from what you say it would seem to be intended to be a Balanced Microphone. Balanced Microphones are not used on any Glider Radio that I know of, but are used as Unbalanced microphones by connecting one leg to ground. A dynamic Microphone produces a low signal level, very much lower than an electret type. The microphone cable should _always_ be screened. If you don't, you can induce noise into the system and this is most probable in an un-balanced dynamic microphone system. It is not unknown for RF leaking from the transmitter to be collected by the microphone cable and re-transmitted as feedback, even with screened cable (of which there are a variety of qualities). I would always try to keep the microphone cable as far as possible from the antenna cable. Tim Newport-Peace "Indecision is the Key to Flexibility." |

use "either colored wire" as Mic INPUT, use the shield and theOTHER colored
wire and use both as MIC GROUND tim Wings & Wheels www.wingsandwheels.com "ken ward" wrote in message ...
