I am a K3 owner and user. I have the KRX3 module installed. What do I
need in order to hear below 500 kHz? Or is this even possible for the K3? Currently, there is a great signal drop off when I tune below 1 mHz.

Hi Dave,
You are out of luck below 490 kHz. Also, you need the general coverage board so that you can tune below 1.8 MHz. There is a bandpass filter that rolls off on the normal antenna jack, (for BCB protection) but you can use the aux antenna jack on the KIO3 strip and get great sensitivity down thru the broadcast band. I am told that you can generate rf as well out of the transverter ports at 1 mw down to 500 kHz, but no luck with 137 kHz with a stock radidio. I use the K3 sometimes to listen to the broadcast band at night. It is very sensitive and selective. 73 Dave K1WHS ----- Original Message ----- From: "W5UN" <[hidden email]> To: <[hidden email]> Sent: Friday, December 18, 2009 1:12 AM Subject: [Elecraft] K3 on VLF >I am a K3 owner and user.

Hi Dave,
You need a BC-453. www.carc.org.uk/pdf/FavRx002.pdf Wes --- On Thu, 12/17/09, W5UN <[hidden email]> wrote: > I am a K3 owner and user. I have the > KRX3 module installed.

Dave,
I ordered a Jackson Harbor VLF mixer based on this discussion started by Jack Smith K8ZOA: http://n2.nabble.com/VLF-LF-Converters-td787815.html I wrote up my results here: "Receiving NDBs with the Jackson Harbor LF Converter ... Elecraft K3, LP-PAN, and Quisk" http://wa5znu.org/2009/06/lfconv/ Jack has a number of modifications for the filters in the VLF converter; I ordered the parts for the new filter but (so far) have not switched over. I was pleased with the results and copied a number of NDBs (best DX was Canada) and other beeps and boops that I had fun identifying. Leigh/WA5ZNU > I am a K3 owner and user.

Jackson Harbor Press has a little converter for 10-300kHz here:
http://home.att.net/~jacksonharbor/lfconv.htm It can be configured for 80 meters or 30 meters and could probably be diddled to provide coverage up to 500kHz. Very inexpensive and works great! No connection to Jackson Harbor other than a satisfied customer.
