The Seminole Texas Amateur Radio Club (STARC) aims to provide a number of online resources to it’s members. Users should take all precautions when visiting a website, even if it is known to the user as being safe. A compromised server can lead to the remote installation of malware and/or the release of private information. Even the best of websites can be compromised, in the event this happens personal information may be exposed. For this purpose it is highly recommended that users assign a unique password to each website they visit and maintain anti-malware software on their computers.
VHF Propagation is a little tricky but thanks to APRS stations beacons having their position tools can use that data to calculate VHF propagation.
- VHF Propagation map: the mennolink.org propagation map is one of the most useful tools for an operator intent on making a contact via VHF.
Using digital modes to calculate propagation is a fantastic way to generate data to calculate and visualize actual propagation.
- PSKReporter.info: PSKReporter.info is an excellent tool that blurs the line between spotting and propagation. The map display is a visually compelling and extremely useful tool.
More traditional tools for understanding propagation are available. The ones listed below are only a small subset.
- DX Info Centre: DX Info Centre is a major resource for propagation, beacons, and spotting.
- VOCAP: the VOCAP website provides HF Propagation Prediction and Ionospheric Communications Analysis.
- NOAA SWPC: The NOAA Space Weather Prediction Center is exactly what it says in it’s name.
