Mike Kenny's transmission list

136-137 MHz

137-138 MHz
The Satellite Band

The frequency band between 136 and 138 MHz was, at one time, reserved for use in space research. Many early satellites had transmission frequencies in this band, and the frequencies above 137 MHz are still used occasionally by new satellites.

Because of history, transmissions from older satellites can still be found in the lower half (136-137) MHz of the band even though it has lost its reserved status.

This list is not particularly up to date - a better, and more-current, list can be found at Mike Kenny's web site.
