gmham, what radio did you use to receive the taxi on as its a bit of an odd frequency to my eyes? Could it have been 173.0625 and maybe it was 'rounded off' by the 'steps'/bandplan in the radio/scanner?

That frequency is a single one, no pairing. It's "Simple UK Light" - one of about 15 channels you can use on the cheap (small fee) as an alternative to PMR446

Yes that is where my mind was going:

http://ofcom.org.uk/static/businessradi ... mpleUK.pdf

There is a taxi firm in my street that has one of these channels programmed into their radios in addition to the usual technically assigned 'taxi business' frequency so that they can talk car to car 'CB' stylee.

As you correctly state, no split.

Strange but true.

Yes thats correct, the OFCOM doc states:

Technical conditions
The maximum permitted ERP for mobile stations is 5 Watts;
The frequencies listed in this schedule shall be used in single frequency mode only;
The use of base stations is not permitted.

But like I stated a taxi firm near me has used one of these frequencies for general chit chat, car to car and base to car for ages without any problems.

Okay thanks so at 5 watts at 173 mhz in mostly built up areas they are not going to achive much in the way off distance then ?! do you get to choose your spot light licence freq or is it allocated ? I know there used to be one on low vhf poss around 86 mhz just wonder if this would have been a better freq to have choosen for car to car use ?

The frequencies are below (as given in the OFCOM doc I posted a link to):

77.6875
86.3375
86.3500
86.3625
86.3750

164.0500
164.0625
169.0875
169.3125

173.0500
173.0625
173.0875

449.3125
449.4000

You choose the frequency or frequencies, which are suitable for a given application is open to a great deal of debate!!

Hardly anybody uses the five VHF low frequencies, not heard a peep out of any of them in 6 years!
