    will this work with my icom using a shure sm58 microphone?

    i ask this because it says it works with a yamaha head set?

    i can make my own PTT switch.

    here is the adapter: W2ENY MIC/PTT Adapter fits Yamaha CM500 Icom 706 7000 | eBay

    It appears that adapter is made for an electret microphone, so I don't think it would do well with a dynamic microphone without modification.

    Lots of info here. I've used the same simple setup in the picture I posted with an IC 756Pro II, FT-950 and Knwd TS-2000. Works beautifully.

    Get a DIN plug and run your audio into the radio through the ACC plug on the back. ;)

    Use these settings as a starting point and you'll have some great audio...

    I did that on the Pro II and compared the two mic audio inputs (not bypassing the mic pre-amp) by looking at an audio snapshot on a spectrum analyzer. No difference in badwidth, freq response or audio quality compared to going in through mic jack. It was kinda cool and looked neater not having a mic plugged into the front of the radio though.

    When I get home ill take a look at all the links posted.
    I picked up a few rat shack mics with the 3.5 jack..... also ordered the ic-7000 plug he offers on ebay. Don't see why it will not work.
    I have a few vocal processors I'd like to try they all use the large 3.5 guitar type plug.

    Really? I didn't observe the audio on a SA, but all on the air reports stated that my audio sounded a lot better running through the ACC plug versus the mic jack. I haven't tried it on my 756 Pro II. I have the audio for it running through a rigblaster pro.

    Morse - When you view the link to Heil's web site be sure to read how to decouple the DC from the audio line. Otherwise you may destroy the mic element. :eek:

    It talks about it in this link:

    Scroll to the bottom of the page and look for the heading: 'DC De-coupling on Icom Rigs'

    When I was running my audio input through the mic jack I installed the cap inside the mic plug. I soldered one lead to the pin and the other lead to the audio wire. Prior to soldering I slid a piece of shrink tube onto the wire (large enough to go over the cap), then slid it down over the cap/pin and heated it so it would protect it from shorting out against the plug housing. You only need the cap on the audio wire, and it must be a non-polarized. If you can't find one you can make one by soldering the + legs of two .5 uF polarized caps together, but it will require more space. Once I switched over to a Heil mic I didn't have to worry about it because the models I use already have the cap installed.
