FOR SALE: Heathkit DX-60B: I have a good working DX-60B that I modified for PTT. It has new power supply filter capacitors and a new three-wire power cord. Add a mic or key, crystal or VFO, and the transmitter is ready to put on the air. The front panel is in very nice condition but the cabinet could use a repaint. Additional photos are available on request. I used this radio until a year ago when I stopped using it as a backup to my homebrew transmitter. Price is $150, cash only.
I will not ship this unit. It is available for pickup at my QTH in northern NJ or I can bring it to NEAR-Fest. I'd be happy to demonstrate it for you. I'm also selling my EICO 722 VFO (see my other ad). If you want both units I'm willing make a deal for the package.; Listing #1764609 - Submitted on 04/10/26 by Callsign WA2MER - IP: 204-11-161-136.affibernet.net; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
