 RADIOHF - Collins Round Emblem Station FOR SALE  
For Sale: 75S3C, 32S3A, 312B4 & 516F2 (no cabinet). Round Emblem MARS units recently fully serviced. The 516F2 has been completely rebuilt updating it with HV regulation, SS relay, as well as buck boost on the AC input. The 75S3C w/SSB & 500hz CW filter serviced, aligned and thoroughly tested. Similarly the 32S3 was serviced, the dual band crystal platform added to update it to a 32S3A, and the speech compressor added. The 32S3A is 100 % except no drive on 80 when used alone. Probably a ground problem; we just could not find it. We think that because using the 75S3C in transceive mode, all bands are 100%, including 80m. The two main S-Line cases need cleaning & repainting. Everything is packed and ready to ship. Looking for fair offer as what I think always seems to be too high :-). See more 1960's boat anchors for sale on my QRZ page: https://www.qrz.com/db/W5JV. PLEASE, NO TIRE KICKERS: SERIOUS INQUIRIES ONLY.

 RADIOHF - Elecraft K3 KRX3 Sub Receiver  
ELECRAFT K3 K3S KRX3 SUBRECEIVER - OPTION -
$334 delivered check , Zelle, or PP FF ok.
$299 with a k3 or P3 purchase.
Or trade for something I can use ??
Removed from a working radio - see list of what you get :
SUBRECEIVER
DSP BOARD
MIXER BOARD
NOISE BLANKER BOARD
KNB3 SUBIN BOARD
KNB3 SUBOUT BOARD
4 TMP CABLES
HARDWARE
KSYN3 - Original version SYN board.
Please see pictures of everything included.
This is a stock picture,as I had 2 of these.
I think everything in this option kit is unavailable at this time from Elecraft,and may never be made again .
Will fit your K3 or K3S rig. If installing in a K3s, or a K3 with a newer SYN board,you will need to get a newer KSYN3A board.
I usually have these in a separate listing.
I think these were around $800 when available.
You will need to obtain filters if you need them,but they are easy.
I have them listed in a separate listing.
Happy to help you if you are not 100% sure how to do this !
