HF Aerial Design - A novel approach to aerial evaluation with diagrams and graphs by G3CWI

A Hanging Rectangular Loop Antenna - A rotatable hanging loop antenna that has been specifically designed for hanging in a tree. Horizontally polarized with a broad azimuth pattern and gain of nearly 3dB over a simple horizontal dipole!

Int. DX Contest Logging program - This program checks for duplicates (including partials), lists multipliers by band, provides a country lookup function, lists all contacts, writes the Cabrillo file format for log submission, and provides many current statistics.

Norwegian ham calls - On this page you can search our online database for Norwegian Ham's.

Luxembourg Callbook - Designed and copyrighted by Norbert Oberweis, LX1NO/KM6RY

DX Radio - FM dx logs, MW carrier offset monitoring, lists of RDS codes in use in the UK, London pirate bandscan and much more from a London QTH.

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.

Vox Recorder  ^{updated  pop} - Vox Recorder is a Windows utility wich allows recording sound from an audio source only when an audio signal is present; its main purpose is to avoid the recording of the silence eventually present at the input. Vox Recorder has been designed in particular for radio-scanner hobbists.

ILIA Software - Logging software to request ILIA award, include a complete list of all italian lake islands references

Stream - Stream is a software that implements MFSK16 and MFSK8 modes designed by me and Murray Greenman ZL1BPU. It also offers a series of experimental modes based on FEC, interleaving and several modulation techniques (PSK, QPSK, MSK, &c.).

WinHdg - WinHdg is a Ham Radio program for finding heading and country information from callsign prefix data

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
