 RADIOHF - Collins 75S-3B with SSB & CW filters  
SN 17256: Collins 75S-3B in good to very good condition. Asking $750, buyer pays shipping, discounted $50 if you come by Gatesville, TX and pick it up. Owned it for decades, rarely used it. Turned it on today and heard signals with only a six foot length of wire antenna. All controls and functions in working order. Full standard set of crystals plus 2.1 kHz and 500 Hz mechanical filters. Power cable is included. Radio could use a bit of dust-off and cleaning but I will leave that up to the next owner. Some rotary switch sections might like to have a shot of Deoxit to quiet them down. Aside from that I believe the radio still works as well as it ever did. No indications above or below deck to suggest that anyone who did not know what they were doing was ever in there with a soldering iron. I can provide pictures above and below deck of this radio upon request. Best ways to contact me are by text message or email.

 RADIOHF - ICOM IC-740 - Works well, looks good  
Up for sale is my Icom IC-740. I purchased this new in 1982 and used it for several years. I took a break from ham radio about 25 years ago an put it into storage. I recently decided to get back into the hobby and had the 740 checked over and aligned. It works perfectly and is in nice cosmetic shape as well. It has a narrow CW filter and I added an internal keyer. Unfortunately, when I installed the keyer board, I forgot that the internal speaker was attached to the case and managed to dislodge the speaker socket from its PCB - so the internal speaker doesn't work (though, if you have a patience, it would be an easy fix). The external speaker jack and headphone jack both work fine. Otherwise, it works well. The power supply is built-in, but this includes an extra power supply cable as well as the original hand microphone. I have more more pictures and a short video if you're interested. $325 and free shipping to the lower 48. Venmo and PayPal preferred. Thanks for looking in! 73, Jon,

 RADIOHF - Elecraft K1 2 Band filter board 20 40m  
Elecraft K1 2 Band filter board came with a bunch of k3 items this week.
$89 delivered - check, Zelle, PP FF ok
I have never had a k1 apart,so I am only going by what I found online.
I am sure someone will help out and tell me what I have.
Also guessing on the price.
I have been told it is 20 and 40 meters based on the markings on the crystals.
Please email with questions.
I have lots more k1 and k2 parts which I do not need.
