I was reading a posting on another forum which mentioned low audio on the microphone element. they stated that the following mic element has more gain. and improved the audio quite a bit just by replacing the mic element . with the g106 with the drilling of the hole this should give quite a bit of push on the audio.

?

what do you all think?

FYI, I did buy some sort of microphone on eBay (looks like something Radar O’Riley would use) and it does have some great audio on it. ?Feel like I need to get a helmet with a spike on it, LOL.

You may be on the right track though. Time to delivery will tell.

David, I just received the microphone thanks for the information. ?

I see it requires 3VDC but appears to have more output than others. ?
Unclear what the G106 output has. ?Of course I had the hole drilled in the microphone for a few weeks now and it did work pretty good. ?

Any guidance on the installation? ?

Well since its a electret condenser like in most mics, i would say that might be the range of voltage on it.maybe the minimum?

?

regular electret condenser replacements? have a range of 1.5 -10 VDC listed on specs on rated voltage. im thinking urs is also rated voltage.

?

?

the mic element is rated for 1 to 10 vdc like the generic condensers.The schematic on the pdf of the mic shows? the mic has 2 teminals one positive one neg. and one + 3v vs

I would just run the power up to the mic via one of the wires that may not be used 2 wires for mic and 2 wires for ptt and both have a common so basically 3. I havent studied the mic wiring in detal but if 2 wires are common to ground, then you could dead end it in the mic by clipping the one ur going to use and tying together the mic ground(-) and ptt ground and feed 3vdc up that dead free wire allowing you to tag the + side of mic with a 2.2k resistor, and of course detaching that wire at radio end so its not grounded. and if the g-106 doesnt have a coupling cap for ac in line at the radio, it can be added in the mic on the + side.

?

?

Just my opinion.

?

Hope this helps.I would do everything i could in the mic so the only thing needed might be a blocking cap for the + coming back from the mic, and jst feeding voltage up one of the freed up wires.Just my hillbilly view of it.

Hi all,

I purchased the mic element from Digikey. ?Yes it does have more output but the clarity is no better than the original microphone. ?

I also purchased the "MASH-style" handset from eBay. ?No significant change in audio and did not work in transmit. ?I would not suggest it.

So we are back to square one. ?I have firmware 1.3 installed. ?
CW keying seems just fine. ?
A probable good change would be to use a different mic case.

Remember folks acoustics is user specific. ?
My voice is not like yours and it still is open for modification. ?
My mic has the hole drilled in it and yes that did help the articulation.
