If you are close enough you will hear both input and output, if you look at the RRUK frequencies they have an R or a T beside them, R for Receive (output) and T for Transmit (input). what you put has 2 R's and 2 T's

Thanks. As I was in the station, that explains why I got hits on both side's frequencies.
As I said, I need more time to get back up to London and do some "experimenting" at other stations :-)

An easy mistake. I travel around a bit but mainly in the north west, I collect rail frequencies...

So.... Sorry for what may seem an silly question.
If I'm going to be at the station/location, would I only need to have entered the "R" frequency??

Thanks for all your help and advice.

Yes, It only has R and T if it's duplex. I have about 30 known rail frequencies in a zone in my radio.

Brilliant. Thanks for your advice. I'll now concentrate on the R side frequencies.

I'm off up to London next weekend on a Scanner trip and aiming to spend some time at the main terminals to see what I get

Happy hunting. I'm rarely that far south these days.
