Small town centre in the middle of Sussex.
Swan Walk shopping centre are licensed for 2 sets of freqs.
TX: 456.35 MHz
RX: 461.85 MHz
With a downfire antenna, so not too far reception from the centre itself. they are on DMR, using mototrbo handsets. Colour code 1, group 100. both slots used, slot 1 security, slot 2 cleaners / maintenance.
Their second licensed frequency is:
TX: 453.5 MHz
RX: 460 MHz
This used to be their 'tenant channel' - a sort of internal shopwatch, but mainly used by the tenants to request bin empties, first aid calls to the centre, etc. There was a time when the centre extended membership of this channel to stores outside, as a sort of shopwatch, but it got too much for most of the stores outside listening to mundane yacking away about bins and spills inside the centre - so a lot of people dumped it.
Forward a couple of years, to now, and the repeater is still on, but nothing heard on the channel - its analogue, and uses 5 tone to identify handsets.
The new shopwatch & pubwatch has appeared on:
TX: 453.025 MHz
RX: 459.525 MHz
Bandwidth: 12.5 kHz
Colour Code: 2;5
(above info from Ofcom wtr). It is in fact colour code 5. Group 1. Slot 1 only used at this time. DMR, and hytera handhelds used. I think they use psudo trunk on the handsets, so in theory the conversation could jump onto slot 2 - in reality, I have yet to see this happen.
