EME resources by DL4EBY - Several kinds of operational data needed for Amateur Radio moonbounce (EME, earth moon earth) communications, the technical challenge amongst the various propagation modes on VHF, UHF and microwaves

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

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
