- [A New Satellite Tracker App for Hams](https://www.ta2wk.com/a-new-satellite-tracker-app-for-hams/): SkyRoof is an open source, 64-bit Windows application for Hams and satellite enthusiasts, available on the terms of the GPL v.3 license. It combines satellite trackikng and SDR functions in one program, which opens some interesting possibilities. For example, all satellite traces on the waterfall are labeled with satellite names, the boundaries of the transponder segments follow the Doppler shift, and all frequency tuning is done visually, with a mouse.
- [Emergency Communications Frequencies](https://www.ta2wk.com/emergency-communications-frequencies/): These frequencies have been adopted into the bandplans of each IARU region to be a focus for emergency communications in their areas. They are not ‘absolute’ frequencies but instead are ‘centres of activity’ and emergency communications may be found ±20kHz from these centres. Some countries may maintain other emergency frequencies in their own bandplans due to local requirements, QRM etc.
