Currently Active APT Satellites:

Satellites transmit between 137.10 and 137.9125 MHz FM using 30-40kHz bandwidth. WXtoImg will function with receivers using a bandwidth as low as 12kHz, but there will be some image degradation. Receiver sensitivity should ideally be about 0.2uV to 0.25uV. You will need a special antenna to receive the circularly polarised signals. Each satellite passes overhead several times a day for about 10-15 minutes. See File -> Satellite Pass List... in WXtoImg for a list of pass times for your location.
