Title: Jellyfish and Cyclops Scratch And Dent Sale
Post by: ChrisSmolinski on February 28, 2020, 1252 UTC

UPDATE, they are sold. Thanks for the interest  :)


I have one Jellyfish and a few Cyclops matching transformers available for half price. Electrically they are fine, I am just not 100% satisfied with the potting, there's less thread around the connectors than I would like. You should still be able to get a good connection.  These are great for matching to loop or longwire/beverage antennas.

$24.50 for the Jellyfish and $14.50 each for the Cyclops, that includes shipping. USA only.  Contact me directly if you're interested.

As per the website, rx only, they are made with #30 wire. You could possibly run QRPp, but no warranty :)
