I suspect this is local, but I'm receiving a weird signal on 422 to 422.4 MHz. It consists of 15 carriers spaced 24 kHz apart. The content is indecipherable, but in wide FM I can hear a ticking sound rather like DAB. I thought it may be a receiver sprog, but it's there on my other two RX's as well. It might be some kind of extended TETRA, but it sounds completely different to the stuff on 390 MHz.
Might be worth a listen.

Re: Weirdness in east Mancs.
Different Tetra systems I guess use different frequency ranges depending on which service use them?. We use Tetra in our work and it's a relatively wide range on our handsets. Always mean to note down what's printed under the battery cover on them but remember thinking it's quite a wide range.
