May be a bit of a long post this one but wanted to give a full background to the question.
Anyone here used to monitoring the power companies over the years on the nationwide trunknet on 139 and 140MHZ?
I monitored them for many years on these frequencies listening to their phone patch type transmissions mainly on 139MHz frequencies hearing them change metres and fix faults at sub stations and faulty meter call outs etc etc. They even ring their families some times on these radio phone patch type systems.
So anyway the voice part of these transmissions disappeared for me or at least in my area anyway for a few years but now they are back
Voice frequencies logged so far the past few months include.....
Its good to get an old user back. they refer to it as a PMR system and today they made a call and said "call me on the digital PMR radio" which got me thinking about the new JRC power wide area 154MHz system talked about in this thread https://ukradioscanning.com/viewtopic.php?f=7&t=4931
about the new 154 MHz DMR Tier 3.
Now I am assuming that he meant this new system when he said "call me on the digital PMR radio" but I have been monitoring this new system and not spotted one voice transmission as of yet? If this new use of the old analogue system is going to die again soon and all go to this new DMR network I would like to follow it. I know shopwatch and security is what most like to hear but this line has always interested me.
Has anyone on here been monitoring the old 139MHz power frequencies or the new 154MHz ones? If so please let me know your findings or how you are getting on and any info about the new 154 system would be good.
