HF voice broadcasts may be terminated if longer than the available broadcast period. This will most likely occur during the hurricane season when supplementary advisories are broadcast in addition to the routine forecasts. Carrier frequencies are shown.  HF voice broadcasts use a synthesized voice "Iron Mike" and use USB mode. ITU channel numbers as follows: 4426 kHz (#424), 6501 kHz (#601), 8764 kHz (#816), 13089 kHz (#1205), 17314 kHz (#1625). Note that stations share common frequencies.

Altus AFB OK VHF/UHF Channelization

Now that my friends is one heck of an elephant walk. All the 29 aircraft involved in the Elephant Walk at Altus Air Force Base, Oklahoma, on Apr. 2, 2021. (Image credit: Rob Stephens / @RedhomeAviation)

The 97th Air Mobility Wing's primary mission is being the Strategic Airlift and Air Refueling Training School for the nation's KC-46 Pegasus, C-17 Globemaster III and KC-135 Stratotanker. They maintain approximately 550 mobility positions available for immediate worldwide deployment. They also act as the wartime aerial port of embarkation for over 27,000 soldiers, and their associated equipment, from the U.S. Army, Fort Sill, Oklahoma, located 50 miles east of Altus.

Here is the latest list of channels loaded into 97AMW aircraft based at Altus AFB (Freq Card).
