"Important changes to VHF channels for maritime safety information broadcasts
From Wednesday 6 September 2017 HM Coastguard will be using new channels to broadcast Maritime Safety Information (MSI) and conduct radio medical advice.

The new channels will be VHF 62, 63 and 64. The use of VHF Channel 10 for MSI and pollution control (back up) is unchanged"



Belfast and Holyhead Coastguards are changing frequency mid MSI Broadcasts for mariners to check signal strengths to those listening, but not every broadcast.

i presume that channel 64 will replace 84. i have stored channel 64 and will find out when the time comes. for now they are doing tests on 62.

No logical reason to presume that.

They currently use:
:23 161.75
:84 161.825
:86 161.925

If they keep the same frequency order these would be used:
:62 160.725
:63 160.775
:64 160.825

But who knows what they will do?

23 will become 62, 84 will become 63, 86 will become 64. I heard it just now from Belfast.

With this change having taken place, I assume that Mountain Rescue teams are now using the new bands at 155.775 - 155.975 and 147.35 - 147.4875
Has anybody heard any activity?

In the last couple of weeks teams in North Wales, Lake District and Peak District on normal channels. Searches on 147.xxx mhz and 155.xxx mhz have been unproductive.

Cant find anything on tinterweb suggesting frequency changes and when speaking with on the Lakes teams they knew nothing of a proposed change but did suggest that digi was on its way.

Anybody found anything on the net?

Is that from the South Stack transmitter or Great Orme?

164.1125 is allocated to Mountain Rescue throughout England & Wales, and paired with 159.6125.
