HF for phone communications

[RR_NDB]

Is HF no longer necessary? Satellite resources, VHF repeaters, etc. are capable to provide what we may need in remote world regions flights?

CYYR to EGPK via BGBW and BIKF

Is HF necessary between North America and Europe? We will cruise at ~ FL 140. The VHF coverage is adequate in this route?

6.6.1 NAT and Anchorage Arctic Regions-SATCOM Voice Use

SATCOM voice may be used to contact Gander Radio for non-routine flight safety calls or during periods of poor HF propagation. Gander Radio may be contacted using Inmarsat short code 431613.

6.6.2 NAT Region-VHF Coverage

VHF Frequencies
126.9 (45N050W – 51N050W)
126.9 (CYFB) (61N070W – 67N070W)

127.9 (57N–63N040W – 57N–61N050W)

NOTE: Notwithstanding the foregoing, aircraft may proceed across the Atlantic without HF radio subject to the following restrictions:

below FL195, routing Iqaluit (Frobay) – Sondre Stromfjord – Keflavík; and
FL250 or above, routing Goose VOR – Prins Christian Sund (or Narsarsuaq) – Keflavík. The aircraft is not allowed to operate in MNPS airspace unless MNPS authority is held.

Any HF for the BBC or Radio-France ?

Your comment is a good one. Indeed, in long journeys we need to watch a multitude of sources. I would like to have a capable HF rig similar the one i have in my D18 Winnebago. (200 W class XMTR, trailing wire antenna similar to E6B Tacamo a/c , etc.)

Unfortunately we will depend on Sat phone instead of the more convenient HF. (that would be nice for base QSO)

Questions:

1) A hand held one like Iridium 9555 works adequately in a PA46 cockpit? Or it is mandatory an external antenna?

2) What about VHF coverage in Russia (at FL 170) in route from EDDB to UUMO, USSS, UNNT, UIBB, UEEE, UHMM and UHMA?

3) Why not an HF RCVR only? (no EMI/EMC issues, light, etc.) Antenna could be...(will think about)


Will put your email in mission team list right now.
