History

Little is known about G22. It was active in the 1980s, but has later fallen into disuse in favor of its Morse code counterpart, M13.

It was re-activated in September 1997[2], with one schedule - third Thursday of each month at 22:00 UTC (November - March: 23:00), within 4-6 MHz range, with ID 186. That was the only schedule of re-activated G22, that remained active until its demise in early 2006.
