Re: No audio in Yaesu MD-100A8X Microphone and yaesu md-100 A8X
¿ªÔÆÌåÓýHi, Steven,? ? ? ? ? ? ? ? ? ?I¡¯ve had a few MD100¡¯s and they have a common failing. The shield wire drops off and you lose microphone ground (not to be confused with signal ground on pin 5). The actual mic is wired to Pin 8 and pin 7. Check continuity between pin 7 as this is the shield wire and microphone ground. ? First you normally get an annoying hum with your audio that eventually becomes no audio. ?This may or not be your problem but I¡¯ve got a genuine brand new mic element here that was bought because I misdiagnosed the element as faulty when it was actually the mic shield/ground wire. ? Also remember the FT847 has an option to have the FM mic gain on the front knob or from a present in the display. The MD100-ADX has really poor gain in my experience. ?Menu 25 FM-Pset. Turn that up to max for testing (level from off to 0 to 63) and also the front mic gain obviously if this is set to off. ? I hope this helps. De Spence M0STO?
