 DIGITAL - For Sale: DVSI AMBE3000 Digital Vocoder
- This is a NW Digital Radio - DVSI AMBE3000 Digital Voice Vocoder on USB.
This was a project I worked on to convert analog audio to digital for DStar, Fusion, DMR and I'm sure can be used for other digital audio modes.
Had these 2 laying around and no longer use. Anyone interested selling for $75 each. I pay shipping.
You can google DV3000 and find a few sites where they sell them and talk about their use.

- RADIOHF - Elecraft K3 KRX3 Sub Receiver
- ELECRAFT K3 K3S KRX3 SUBRECEIVER - OPTION -
$284 delivered check , Zelle, or PP FF ok.
$244 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 !

- RADIOHF - Drake C-line
- Very very clean Drake C line. R-4C with no extra filters, T-4XC, MS-4, AC-4. Excellent cosmetics on all units 9+ of 10. I have owned this C Line for twenty five years. Have used the R-4C / MS-4 recently. Am using my TR-4C more so havent used the C Line much over last few years. Hate to see it just sit there. Had a family member pass suddenly last month and have had to clean out her things. Now I think I need to reduce the number of radios, etc. so my XYL won’t have to! All units work but AC-4 has never been recapped. R-4C missing the silver tuning dial insert plate. Otherwise fine.
Prefer not to ship but will on your dime. Would need 4 boxes.
$550 for all plus shipping if needed. PayPal (you pay fees), MO or cash or personal check (ship after clears). I don’t think you will be disappointed. But no returns, as-is sale. Thanks for looking.
More photos upon request.
