Elecraft K3 KRX3 Sub Receiver: ELECRAFT K3 K3S KRX3 SUBRECEIVER - OPTION -
$279 delivered check , Zelle, or PP FF ok.
$239 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 !
