Minnesota DX Club - The MDXC has monthly meeting in the Twin Cites. Coverage all bands from LW to UHF. We also have Summer and Winter DXpeditions.

Scanrec Scanner Recorder - Scanner Recorder (Scanrec) is a free audio recorder that is primarily designed to record speech. It has a VOX control that allows the user to save disk space when no sound is present in the signal. Since FM communications has such an effective squelch, the recorder works best with FM. HF ham bands and World Band radio have such a poor signal to noise ratio that the VOX gate on Scanrec might not be very easy to set.

QSO Manager - HF QSO/QSL/Award managment, ADIF Import/Export, full version free to everybody. Requires Access 97 or Access 2000 (with JPEG and TIFF filter installed), screen resolution 800x600/1024x768

BeaconClock - Freeware real-time, schedule of the transmitting times, frequencies, short-path and long-path beam headings

BeaconSee - BeaconSee shows you, in real time, worldwide HF band openings on your PC. Analyses the audio signals from your radio, which is tuned to the NCDXF IARU HF beacon network and shows you the signal strength received from each of the 18 beacon transmitters as a plot of frequency spectrum against time.

Voice Descramble - This program descrambles band inverted encrypted transmissions, usually found on VHF/UHF. It uses a NCO (numerical controlled oscillator) to re-produce the originally inverted audio band.

VHF Logging program - This program checks for duplicates (including partials), lists multiplier grids by band, lists all contacts, writes the Cabrillo file format for log submission, and provides many current statistics by N3FJP

Ionospheric Simulator - This program simulates a HF link, using sound card and WIN95 by Michael Keller, DL6iAK

ERGO Radio Software - Creative Express Corporation software to enhance shortwave radio listening. Support for Drake R8A/B, NRD535/D, WJ HF-1000 and TEN-TEC RX-320 receivers, as well as propagation, path evaluation and database management.
