Hidee ho everyone. Hope all had a good Christmas and will have a healthy and Happy New Year!!

I purchased a Heil SB-2 boom for my mic. I have an MC-60 and want to use the base with the PTY and Lock.
So in order to do this I needto add wire to the desk unit so it will reach up to the mic in the boom cradle. About 24in should do it.
I was wondering if I could use telephone cable wiring in the white sheath?
Thanks.

I would advise using a screened cable rather than telephone wire.  This will keep stray RF out of your mic and allow you to make a balanced connection to the transceiver mic input.

Universal has what I need.
#2112 and #0526 plus the Heil Mic wire #2645.

You can probably get away with it, however, a shielded cable would be a better choice.

Wire the boom mike directly to the transmitter with shielded cable. Then run a PTT line and ground from the transmitter to old mike base for PTT control. If you use unshielded telephone wire you are asking for problems with RFI, hum, noise and distortion on your tranmit signal.

On second thought - I'd set the MC60 aside rather than "butchering" it by tapping in wires. I'd get a foot switch to use for PTT with the boom mike. Most rigs have an accessory connector on the rear that has a PTT and ground pin that you can wire to the foot switch. I think Heil even sells a foot switch.

No butchering involved. The Heil mic wire is shielded and the 8 pin conectors are female and male. So I can make it so I use the MC-60 base for PTT or Lock or Vox.
