NCDXF Beacon for Android - NCDXF Beacon is a simple tool to monitor the NCDXF beacons on the Ham Radio bands 20m, 17m, 15m, 12m and 10m. Upon start the the time will be synchronized with an NTP server.

APT Decoder - APTDecoder is a free software for recording and decoding signals transmitted by NOAA POES APT enabled weather satellites. It is run on a NT-based version of Window

The Milli Beacon - This page describes an cheap RF signal source, a portable micro beacon, using a low cost temperature controlled crystal oscillator

OZ2M - Next generation beacon - Next Generation Beacon hardware platform encompasses both analog and digital modes, i.e. CW FSK and MGM in a mixed mode configuration. The advantage of the mixed mode is that humans can decode the CW FSK by ear and the MGM can be decoded by computers way below what is audible. Therefore the MGM can be used for “pre-human-conditions” or early warning monitoring.
