In early February we posted news about the release of a program called GridTracker. GridTracker is a live mapping program for WSJT-X which is a software decoder for low power weak signal ham communications modes such as FT8, JT4, JT9, JT65, QRA64, ISCAT, MSK144 and WSPR. Although these are low power modes, the protocols are designed such that even weak signals can potentially be received from across the world. Mapping the received signals can be interesting as it may give you an idea of current HF propagation conditions.
Previously GridTracker was Windows only software. However recently GridTracker was updated to now include support for Mac and Ubuntu (Debian) operating systems as well. This is great news as it makes it much easier to set up a portable GridTracker screen on a portable computer like a Raspberry Pi.
