Flex SDR-1000 Nice Condition: >>PENDING<< F/S: I have a decent Physical Condition Flex SDR-1000. This was an impulse buy. But don't have a PC with Functional Parallel Port. I did power it up, no smoke, no smells, just the power indicator lit-up. Check the Pic. I did clean some Foam Filter Material from the Fan Grill. Not really interested in chasing down an older PC and getting it running.; Listing #1768804 - Submitted on 05/22/26 by Callsign W1DIO, Modified on 05/22/26 - IP: syn-047-231-033-128.res.spectrum.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
WTB: Elecraft K3/10, No ATU, Just Basic: Looking for a later # K3/10 with standard filter OK. Must have KXA3a or newer. A narrow CW filter would be nice. Latest firmware installed. Scammers forget it, I vet everyone before contact. Please include photos, serial # and accessories. Price + shipping to 75771. Include a phone # and we can discuss.

4Sale: Flex 6400 with ATU: PRICE REDUCED! I have for sale a Flex 6400 with ATU. The Flex is well packed but not in original box. It comes with a new Flex mic, power cord, ethernet cable, and copy of quick start guide. It's in excellent working and cosmetic condition. Asking $1,650 shipped to your CONUS QTH. Greatly prefer PayPal for payment, F&F unless you pay the fee. Zelle and USPS Money Orders are the only other acceptable forms of payment.
[There is no photo accompanying this ad because the radio is already packed up, and I don't want to unpack it just to take a photo. Please look up my reviews on the qth.com feedback forum by searching on my callsign, and you'll see I'm an honest trader who stands by what he sells.]; Listing #1768582 - Submitted on 05/19/26 by Callsign N8VZ, Modified on 05/22/26, Web Site: http://www.n8vz.com - IP: syn-024-210-019-143.res.spectrum.com; Click to Contact -- Send this Ad to a Friend
