HFGCS Scope Command HF ALE Network - Update 23 January 2023

HFGCS ALE Network frequencies USB/ALE (scan channel number): 3137.0 (1) 4721.0 (2) 5708.0 (3) 6721.0 (4) 9025.0 (5) 11226.0 (6) 13215.0 (7) 15043.0 (8) 18003.0 (9) 23337.0 (10) kHz 

 The ALE system used by the JCS HFGCS network is designated MIL-STD-188-141A. You can download a software program developed by Dr. Charles Brain to decode these digital transmissions at http://hflink.com/beta/. You can also use F6CTE's Multipsk program at http://f6cte.free.fr/index_anglais.htm. It is my favorite multimode program and always gets a workout in the Btown Monitoring Post. ALE allows automated ground agency contact by selecting the best station and best frequency without operator interaction. ALE radios make this possible by using a data file that contains frequency, station, and other pertinent information. For ALE radios to operate properly, the radio must have loaded datafile, be turned on in the “automatic” mode, and remain there for the duration of the flight. If the radio is removed from the ALE mode, history tables will require time to rebuild and initial communications may be slightly degraded.
