It's a VHF FM transceiver. Channel 16 is the calling channel and it's simplex on 156.800MHz. It has the most used channels fitted unless someone's removed the crystals! Crystals these days are rather expensive now that synthesisers are so cheap!
You might be able to hear Humber Radio on channel 16 but I don't know what your local band plan is. It should all be on here.....
