Channel 0 is what it is...156.000Mhz

But apparently there are repeaters (although I've never heard one whilst I've been on the coast).

Its a bit old but was discussed on this thread.

I've heard 162.4 (:36) used as a repeater for :0 in the Tenby area of Wales.

Seems to be some uncertainty about 160.6, it has been said to be ":00" or ":99", personally I suspect :00 since :99 is in theory 157.975 / 162.575

You can understand people getting confused by a channel numbered "00" , but if that is how it is keyed, and what the display shows…
KEY : = channel/stud | ~ = CTCSS/DCS | ^ = transmitter site | ¯ = overhead | * = trunked

Just a wild guess, but a radio with numbered channels from 0 to 99 wouldn't be able to handle a channel called "00". Maybe, in order to avoid this issue the MCA/RNLI decided to change it to "99" as a work around, even though according to the bandplan it's really "00"?

It would if it was programmed to recognise "00" as a channel ID rather than a number, just as it might be programmed to recognize "16A" and "16B'.

Ch 16 is always 156.8

A frequency page online says "Channel 99 (160.6) started life as channel 00, but apparently 00 is what the coastguards dial into their consoles to clear them!"

So they wanted to call it 00 but had to call it 99 instead.

I know someone who voluteers for the Coastgaurd and they use CH99 (160.600) to talk to each over and use CH0 (156.00) to talk to Humber who are the Coastgaurd HQ for the North of England.

A CG volunteer told me that the channel number 99 was made up to avoid confusion between 0 and 00. At one time 160.600 was broadcast from CG repeaters but 156.000 now used and "99" is the back to back channel for ops. Used nationwide.
