ANNOUNCE - New scammer: If you come in contact with a gentleman name Richard W Ewing, Call sign KO7N his address is valid. He is a scammer. He will make an agreement with you and then want more money, thus breaking his agreement. I can send you an email that I wrote him documenting mostof the rransaction. He refuses to either send me the radio, or send me my money back. It's a long story, but I am willing to give more details. Right now, he owes me $350. He wishes me to send him another Applecard for $25. I have told him no. Anyway, seems to me, he listed here a whole bunch of stuff. Have nothing to do with this guy. He'll make an agreement with you, and then he will want more money. His wife died of cancer, he might play that angle. You are now warned.; Listing #1760135 - Submitted on 02/25/26 by Callsign KF6TI - IP: 73.232.253.228; Click to Contact -- Send this Ad to a Friend

MISC - 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.
