I have for sale a Yamaha CM500 headset in perfect condition. I used it for one Field Day event and haven't used it since. It comes with a heavy duty Motorola foot switch from a police dispatch console that is made up (by me) with shielded cable to combat any RFI. Also includes a custom built (also by me) adapter Y cable wired to hook these two items to a Kenwood HF radio with the 8 pin mic connector. Also included is a 1/8" to 1/4" headset jack adapter. Price is $95 shipped for all. Paypal or Postal MO accepted for payment. If interested, please contact me via the email address listed under my call.
