Hello
I have a Tigermoth and have just fitted a Trig VHF com, 12v .
Impedance of the set is 300 ohms.
My Campbell Classics flying helmet always had issues transmitting, always garbled to the reciever. I could always hear just fine , transmit was always readability 2 !. Helmet has a 2 position switch to internally match mil to ga impedance as required, tried both, settings ,no luck.
To resolve the issue I parted company with the Icom a200, installed a new aerial set up, VSWR 1.5, and have now decided to replace the mic in the headset.
I purchased a Pilot USA branded Electret Mic that need a voltage supply to operate. How can I hook this into my existing system ? The old carbon dynamic mic is non powered. I unable to locate any info on this any where, was hoping some instructions may come with the mic, but doubt it. The mic is the PA-9EHM
version specifically for high noise environments like the Tiger.
Happy to make a battery box if thats whats needed.
Any help here would be greatly appreciated.
