Hi all,
I have come across this system which over the years appears to have replaced some MPT1327 systems in the UK and Ireland.
MPT1327 control channels would go silent, then be replaced by this. I have never found out what it is.
It is active in the 165-170 MHz region in the UK, and 420-430 MHz region in Ireland (Dublin Bus are users, so may be some sort of Tait proprietry trunk system?)
Any help is greatly appreciated. If it is the wrong section, apologies, let me know where to put it.
Attached is a picture of the spectrum, and a google drive link to a WAV recording
