Check Heil web site for a blocking cap size. Maybe 1 mfd?

Subject: Re: [WriteLog] Heil -> .WAV files
Rick,
Not much help (it is too early in morning for brain to wake up) but I see
that I have a "special" cable I make to take my Heil Icom mic to the sound
card. There is something you have to do. After I did the cable, mine worked
much much better than the older "comm" element with the external mic preamp
i built.
I will look for notes today. But just thinking about it, you have to get
the dc voltage to the mic on the single mono wire - so my guess is: the
mono wire goes to the ring end of the stereo plug and a small cap goes from
ring to tip.
Jerry, W6IHG
PS Found my notes that say -
- has a special adapter cable for the radio because the DC (7.0 volts)
feeds thru to the microphone element.
- on the sound board there is 3.6 volts on the "ring"
- Need to wire an adapter cable for use with the new headset and the
computer.
