Oceanic Question

#1 Post by Duncan White » Tue Nov 13, 2018 10:36 pm

… Auckland radio accepts primary guard this frequency, secondary ???.?, standby SELCAL check …

What secondary frequency does NZ use ? 122.1 ?

What is the point of saying "secondary ???.?" if the controller is not monitoring a secondary frequency ?

Is it something to do with CPDLC ?

Yep, 122.1.

It's not something with CPDLC, its due to having a backup frequency in case comms is lost, which in the real world with HF radios, multiple stations are sharing the same HF frequencies so having a secondary helps making contact with the right Oceanic FSS through HF radios.

Auckland Radio uses the following HF frequencies in real life:
3.467
5.643
8.867
13.261
17.904

As far as I know, all Oceanic stations in the Southwest Pacific (Nadi, Auckland, Brisbane, McMurdo) use and share the same frequencies depending on the time of the day and the position of the sun. So having a secondary frequency really helps. We tend to simulate secondary frequencies because of the sake of simulating HF via VHF due to VATSIM's limitations. But I bloody hope sometime VATSIM or other networks simulate HF, accurate SELCAL and proper easy to use CPDLC that can be easily accessed.

(ps: I wouldn't call it a limitation, rather VATSIM not being bothered with more functionality and keeping the same ol network from 2001, which is just years and years old.)

Duncan,

When you log on as a OCA controller you have the choice of setting up 122.1 . If you choose to do this please note that it will be a text-only frequency and to reply on that frequency you'll have to turn off your text on 128.9 or whatever primary frequency you're on.

If you don't use the secondary frequency just don't say the second part because like you said if you aren't as the controller monitoring it don't bother.
Cheers,

Cam Tyson
