[Elecraft] NCDXF/IARU Beacons

[W6NEK]

I wrote a simple Windows program that identifies the NCDXF/IARU Beacons.
It's a software simulation of the MFJ 890 DX Beacon Monitor.
A description and download are available at:
http://www.w6nek.com/

Scroll to bottom of the web page to download the free HF Beacon Tracker 
program.
