• VHF APRS Propagation Map - VHF – Based on realtime APRS reports. This map shows real-time radio propagation from stations operated near 144 MHz. It uses data gathered by Automatic Packet Reporting System-Internet Service (APRS-IS) from packet stations in the amateur radio service. The map shows activity from the past hour. Paths are smoothed to create a color-coded footprint indicating the distance VHF signals are likely to be traveling.

• Using PSK Reporter as Propagation Tool - PSK Reporter,is a powerful tool for monitoring your FT8, JT65 or PSK signals around the world. But, even if you are not transmitting on any of these modes it can still be a great propagation tool for determining which bands are open and to where in the world signals from your area are being heard.

• WSJT-X Download Page - WSJT-X - Weak Signal Communication, by K1JT - offers specific digital protocols optimized for EME (moonbounce), meteor scatter, and ionospheric scatter, at VHF/UHF, as well as for LF, MF, and HF propagation. The program can decode fraction-of-a-second signals reflected from ionized meteor trails and steady signals more than 10 dB below the audible threshold. WSJT-X incorporates nearly all popular capabilities of programs WSJT and WSPR, while adding comprehensive rig control and many other features. Open-source, download latest version for Windows, Linux, Macintosh OS X.
