Thanks Paul. I hear what you’re saying but now I’m even more confused. All of the marina guys use handhelds that monitor 80/37. I also hail our little water taxi on 80 (addressing with a slightly different call sign). I transmit on 80, they reply from a 16 foot launch on 80.

The guys in the marina must be using hand helds set to the shore based frequencies, or they couldn't converse with ship sets.

If you want to check that your fixed set is transmitting on ch80, set your hand held to the US channel set, which wiill TX and RX on 157.025, it will receive from the fixed set, but cannot transmit back to it.

Is it possible you always used to use channel M to speak to the marina? A simplex channel.

And you switched to 80 for whatever reason and found it behaved differently?

Unless you are using an Icom VHF, where M=80, duplex, see post #6

Have in past accidently pushed something on my marine radios and found the radio working on the "wrong" set of frequencies, usually only discovered when trying to enter a marina.
This means a scramble for another radio and yet again finding the manual to put it back gain.
Have in the past supplied a well known marina operator with VHF radio equipment.
The marine radios were capable via the programming software of operating on a private inter marina communications channel allocated by Ofcom.

That's a good idea, will do!

Didn't notice that in the post.

My handheld ICOM, a newish M25EURO, has the relevant channels named 80, 37A, and P4.

37A and P4 were shown as M1 and M2 on earlier sets.

And before that it was 37A which was known as M.

My point was that 37A aka M aka M1 is a different channel to 80. If people think M is the same as 80 that's confusing.

Yes, both of my sets have suddenly failed to tx or rc on 80. I’ve tested most of the common simplex calling channels between my two sets and no issues whatsoever. The third set engaged in this ch80 debacle was that of the marina staff. Still no joy.

The difficulty being that it was a miserable January day with zero local traffic so we lacked any other transmissions to assist in troubleshooting.

Presumably the set you are calling is set up/working correctly?

Not disagreeing James, the only people i have seen that call M 80 is Icom
