82.025

Does anyone know what this frequency is?
Im listening to it right now at 2:30am and there is a bunch of guys talking on it, sounds a little dodgey to be honest, not quite sure what they are talking about exactly..

One of the more quiet frequency's that im trying to work out but at this time of night you dont expect many people to be broadcasting really.

Also what usually operated around 80. anyway? i tried to look this up on google and it said it was some frequency ofcom actually use apparently?

Its coming in pretty clear from Hamilton area on a standard antenna so im not sure how far it could possibly be.
If anyone has any ideas that would be a good help, thanks!

Okay at first since there was quite a few guys talking on the one frequency it sounded like they were all calling from base stations but some are at least mobile as they are now talking about certain locations, one of which was hope street/bath street which of course is in Glasgow city center.

Not sure if this is a taxi company or not since most seem to operate on higher frequency's and the chatter is not the usual taxi service talk.. im hearing them having random conversations, one guy is called 'Gerry'.
They are also saying that they have each others phone numbers..
Signal seems to be getting weak right now compared to before

There is a taxi company in Busby that use Low band - because their office is located in a dip just near the railway station - their aerial is on a massive pole.

There will still be taxi companies about on it.

Keep listening - something will give it away sooner or later.

Just looked up an old copy off the uk scanning directory-8th edition and see that 82.025 is listed as a taxi company freq, in this case it was a company down south but yep seems taxis still use this range off freqs,

this base tx freq was paired with 68,5250 mobile

There's a whoie load of PMR channels down at 81.5875 - 83.5-ish
with the mobile side -13.5 lower at 68.0875 - 70.0-ish

"low band" isn't just in the 85 - 87.5 area :)

Do you have to be licensed to operate PMR on low band? and what is the purpose of PMR on low band anyway.. and what kind of people would be using it?

This might very well be a taxi company but im still not sure, these guys are just using their radios to talk about anything really and not much talk about locations or pickups at all.
If it is a taxi company its not the usual chatter you would here compared to other frequency's.



gmham, when you say this base tx freq was paired with 68,5250 mobile what do you mean exactly?

Im new to scanning and have tried to learn as much as i can but i just never understood this part yet.
My understanding was that the base would be on one frequency and mobile units on another and they would listen to each other BUT i am hearing the two sides of the conversation, in fact its more than just a two sided conversation with many people talking in a group conversation.
Other taxi frequency's i listen to i just hear dispatch talking to drives but cannot hear the drivers talking back, one example is 440.125, thats the most active frequency on my scanner and its all one sided.
I have yet to find out what company it is and gain their other frequency's used

You have what is called simplex and duplex, simplex means all broadcasts are transmitted (tx)and received (rx)on the same frequency.
duplex means the radio transmits on 1 frequency and receives on another, this is mostly like taxis ect.
so example is the taxi base tx: 85.8375 and rx: 72.3375
and the taxis out on the road tx: 72.3375 and rx: 85.8375
so only the base hears the cars and other cars dont hear each other.
now systems can also have talkthrough where all tx and rx can be heard on the base frequency of 85.8375.
there is a lot of other types and systems but that is a basic guide to how it kind of works.
the tx and rx frequencies are allocated by ofcom so its not any old frequency you can choose to tx and rx on.

see http://en.wikipedia.org/wiki/Two-way_ra ... x_channels
to explain simplex, split frequency simplex, talkthrough via a repeater etc.

440.125's mobile side should be 14.5 lower at 425.625

john oliver may well be a driver who just happens to be the licence holder, i know 1 of my local taxi company licence holder was just a driver and didnt own the company.
i have monitored this freq for a good bit of the day and not heard anything, it may well have been the weather conditions that made it a strong signal in hamilton last night as weather can affect how far a signal travels.

Thanks for the info guys, i appreciate it! i understand now

And no its now im Hamilton, haha i looked it up and its about 14.2 miles away from my location.
I shall try the RX frequency tonight!

Its kind of a bother for me to monitor two frequency's tho, i cant set my scanner up to scan just 2 channels.
I have 10 banks and each band have 10 spaces so just hear these two frequency's i have to use a whole free bank up! i might keep a few clear to do this anyway, depending on how interesting the traffic is.

Do you know what taxi company this is? i have been looking for things to listen to in Hamilton but have yet to find anything to be honest until i seen this post.
Also there is some kind of big shop/office on PMR446 channel 4 but ive yet to work out what the hell is it because they way they they are speaking on their radios is confusing, mostly looking for people to go on breaks in big numbers (12-20 people at once!) and also ask about customers via their radios.
Ive only picked them up using PMR radios tho and not my scanner so far..


I have set up a bank for John Oliver's taxis and put in the two freq and have it scanning away but the only one in use is 82.025, i have received nothing at all on 68.525, not yet anyway.
I can pick up stuff in Glasgow no problem it seems, im not sure how far i can pick things up from tho.
J.O taxi signal is a bit fuzzy from when i was listening before, i guess the weather had something to do with it like scottyboy said.


What area are you listening from scottyboy ?? sometimes you can get nothing on this freq for a while and then next thing it lights up with conversation, especially at night time it seems.
I can hear them talking right now actually but it was dead for a while.

I was also thinking about what you said about duplex, that the taxis only hear the base and the base can only hear the taxis but what happens when more than one mobile unit is trying to speak at once!? i can see that getting confusing at times because some of these people dont bother with callsigns all the time.

A quick search with google found Boulevard and Drumry Taxis listed at that address.

I suspect it is a registered office rarther than the transmitter site because I can only see a mast that looks like a cellular base on google streetview.

OFCOM uses an unusuall coordinate system for the transmitter location.
I cant remember how to convert NS 520 713 into something usable with google maps right now, I have a note somewhere.

Nothing unusual about it - it's standard OS grid references.

NS 520 713 = 55°54′44.75″N 004°22′07.04″W
