ANNOUNCE - Scammer Alert: Just had someone using the callsign AD8QE and the correct associated operator name respond to one of my WTB ads through direct email channels and not the QTH messaging. He supplied pictures of what I was looking for with a very skillfully (possibly AI generated) added in card with his callsign and today's date. Problem was, I recognized the photo's from a previous swapmeet listing three months ago over on QRZ. Same exact photo's, he was just able photo-shop in a different card than the originals. So, beware of AD8QE...use due diligence.; Listing #1763419 - Submitted on 03/28/26 by Callsign W3TKB - IP: undefined.hostname.localhost; Click to Contact -- Send this Ad to a Friend
RADIOHF - FS: KENWOOD TS-590S: PENDING...I need to purge my collection of radios. I have a gorgeous Kenwood TS-590s for sale. I have the original box, manual, power cord, and microphone. This radio is near perfect as-new condition cosmetically and 100% perfect operationally.
Separately I am selling the matching "upgraded" SP-23 speaker which is absolutely mint. I prefer local pickup so you can try the radio out on the air but will consider shipping. Feel free to ask any questions or come try it out on the air. Asking $595 plus shipping but I am willing to drive a reasonable distance to either meet or deliver. If shipped will be double-boxed.
Would consider an as-new Yaesu FT-891 in trade.; Listing #1760570 - Submitted on 03/01/26 by Callsign WU2U, Modified on 03/28/26 - IP: syn-098-003-051-196.res.spectrum.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
