Packet Stuff to find a new home

I have some Ham Radio TNCs, BayCom Modems and a Radio to find new home.
Whether for APRS or setting up a new node, theyre yours for the cost of the
postage (and a donation if youre feeling super generous)! I have weighed
each item alone, but there will be a few hundred grams for packing
materials and a box to consider, too.




Theres also a working Tait T500 (RX & TX on frequency. Not thoroughly
tested, believed to be fine) that is wired for any of the Kamtronics units
(radio has 9-pin D). Item #12.




Ive taken a bit of time to test them quickly. The results are in the table
below. These devices come with no guarantee. Theyre all older than me! Sold
as seen! Pictures below, too! If it explodes when you plug it in, tough!




Contact me if youre interested in any of these items first come, first
served. I also have a job, so if I dont reply right away, hold fire!
