AMSAT CubeSatSims: The orange one made from PCB's is sold. Still have one.
I have 2 CubeSateSims from AMSAT. One was from a kit and the other was built using PCBs from AMSAT. I sourced the parts and printed the frames for that one. They were fun to experiment with, but I'm getting away from satellite work right now so these need to go to someone who will use them. The kits are currently listed for $550 on the AMSAT website, when they are available. Mine are $300 each, shipped. Paypal, Zelle, check, money order.; Listing #1760113 - Submitted on 02/25/26 by Callsign WR7D, Modified on 02/25/26 - IP: dsl-208-98-139-129.fmtc.com; Click to Contact -- Click Here to View Picture -- Send this Ad to a Friend

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.
