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 !
