- RADIOHF - Elecraft K3 KRX3 Sub Receiver
- ELECRAFT K3 K3S KRX3 SUBRECEIVER - OPTION -
$275 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 !

- RADIOANQ - National NCX-5 MK 11 /W Power supply
- National NCX-5 MK II $350 W matching power supply in kinda sorta working
The radio receives, and the radio transmits , The transmitter puts out over 100w on 80m down to maybe 60 or so on 10m. It is in need of an alignment as the receiver is sensitive on the CW portion of the bands and the phone portion. In the CW portions, it's actually a pretty hot receiver. RF gain control is scratchy but works
. The part I could not get dialed in was the rx/xmt alignment. xmt frequency was always off by maybe 300 hz from receive. This is a known issue with these radios and can most likely be overcome by someone with the proper knowledge.
The power supply works as it should.
Comes with a Nice Mike and a Manual
