Antennas for Weather Reports - Radio receivers and methods to improve reception of weather radio broadcasts

How to build a tuned loop antenna  ^pop - How can you vastly improve your Medium Wave reception? its quite simple really, all you need is 120 foot of wire, a few lengths of timber and an old tuning capacitor with which you can build the answer to every DX'ers prayers, a tuned loop antenna.

Satellite Antenna Tips  ^pop - Tips that may be of help with the most important part of an amateur radio satellite station, the antenna systems.

CB DXPacific Propagation Priority listing - Eleven meter world-wide propagation predictions for South Pacific updated monthly. Also, Near Real-Time DX Monitor

OKDXF - OKDX Foundation is a non profit organization the aim of which is organizing and funding radio amateur expeditions to rare countries and regions where no or low radio amateur activity exists.

About GMT & UTC - A Few facts concerning GMT, UT, and the RGO by Rdio Netherland

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.

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.

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.).

CW Player  ^pop - Simple freeware program generates Morse caracters and Q codes. It needs a sound card and Win95.

WinPSKse - WinPSKse is a logical outgrowth of WinPSK as designed and written by AE4JY. The look and feel is intentionally similar, but some significant changes have been made, not the least of which is the ability toreceive two PSK31 signals simultaneously.

PathSim - PathSim is a Windows program that can be used to simulate radio propagation paths using a soundcard and/or wave files as the source and destination.

Radio Clock - Enables you to decode the time signals sent by various LF and HF radio stations in the standard frequency and time service

WL7AML Intermod program - This program will run all possible combinations of every transmitter against every receiver in its list
