The best HF
frequencies to listen out on would be:
8864 KHz - reserved for aircraft of North American registry. We share this with Shanwick and Iceland.
8879 KHz - reserved for aircraft of European registry. Also shared with Shanwick and Iceland. This is an interesting frequency in that quite a few ground stations in the Indian Ocean/Oceania use it as well. Generally early in the evening (2000Z) we will start to pick up these ground stations and aircraft. Some of the ground stations we'll pick up are Mumbai, Melbourne, Dar es Salaam, Mauritius and Seychelles just to name a few. Quite a few times I've spoken to the likes of SAA, MAU, QFA, CPA and others. It's generally amusing to hear the flight crew reaction when they realize they are talking to Gander.
8831 KHz - independent of registry, shared with Shanwick.
These are the three "primary" daytime frequencies and as such are generally always used. During the peak traffic periods (from approximately 1400Z-1800z) we will also use a few others:
13291 KHz or 5616 KHz depending on propagation. We're in a cycle now where the higher frequencies are generally better so most likely 13 MHz. American registry.
11336 KHz - we use this most days but have a problem with an adjacent broadcast station causing splashover. 6622 KHz sometimes used instead.
8906 KHz or 8891 KHz depending on the location of the tracks. 8906 Khz is used for southerly traffic (shared with New York, Shanwick and Santa Maria - can be the proverbial zoo). 8891 KHz is generally for northerly traffic (shared with Shanwick, Iceland, Arctic and Bodo).
