MFJ-1279 Deluxe Sound Card Open Box: This new, open-box MFJ-1279 Deluxe Sound Card Interface is the perfect solution for running FT8 and other digital modes — PSK31, RTTY, SSTV, JT65, and more — on any HF transceiver without a built-in sound card. A step above the MFJ-1275, this deluxe unit packs in everything you need: transformer coupling that eliminates ground loops, hum, and RFI; a direct keying jack for effortless CW or FSK operation; an aux input for connecting external audio devices like a camcorder or VCR without ever swapping cables; front panel switches for monitoring, on/bypass, and VOX/Manual PTT control; and a built-in 1/4" stereo headphone jack. $75 shipped CONUS.; Listing #1760880 - Submitted on 03/04/26 by Callsign W1MBB, Modified on 03/26/26 - IP: 23.124.38.7; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend

4Sale: SCS PTC-11 PACTOR Controller: PRICE REDUCED: I have for sale an SCS PTC-11 PACTOR Controller. I used it briefly about a year ago for Winlink and also for HF Packet.

It'll come with cables to connect to Yaseu rigs (8130 & 8120) as well as cables to connect it to an Elecraft KX3. Also a power cable and a serial to USB-C cable will the supplied. Manual available online. It is in excellent working condition and good cosmetically. Will ship to your CONUS QTH for $435. Greatly prefer PayPal for payment, F&F unless you pay the fee. Zelle accepted. Only other acceptable form of payment is USPS Money Order. No personal or cashier's checks.; Listing #1760902 - Submitted on 03/04/26 by Callsign N8VZ, Modified on 03/20/26, Web Site: https://www.n8vz.com - IP: syn-024-210-019-143.res.spectrum.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend
