Wireless remote Headset for Icom/Yaesu: Offered, for your consideration, is a wireless headset with microphone and earphone. I have restored and repurposed the Plantronics product for amateur SSB/AM use. I originally provided these for some severely handicapper hams. I am amazed at the transmitted audio quality and fidelity. The microphone is noise cancelling. The wireless headset utilizes the transceiver’s VOX control. Installation is simple only requiring VOX adjustments, Microphone gain and compression level. Included is the Plantronics device, prewired connection cable for either Yaesu 8 pin Round or RJ-45 connector or Icom 8 pin round connector, headset, ear piece, 9-volt wall wart, microphone and instructions for use. Please contact me if you have any questions.
Offered at $119 or reasonable offer. Payment by check or USPS money order. Sorry, no PayPal.

Satellite setup: I have a satellite system for sale. I've decided it just isn't my thing and want to focus on other aspects of the hobby. I would really prefer a local pickup or meet up within the area. The antennas will be extremely difficult to disassemble for shipping so those won't be shipped. Everything else I will ship. The IC-9700 in the picture is not part of the deal unless it makes a difference in the sale of the whole package. Prices listed are plus shipping. The system is still currently installed so may take a few days to ship or be ready for pickup.
M2 Leo-Pack antennas, $450
CSN S.A.T. controller, $200
Yaesu G-5500DC with separation kit, $550
2 50ft lengths of LMR-400 with N and PL-259, $125
2 7ft lengths of LMR-400 with N on both ends, $35
2 rotor cables, on 45ft and the other 55ft. $75; Listing #1760115 - Submitted on 02/25/26 by Callsign WR7D - IP: dsl-208-98-139-129.fmtc.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
