[TheList] Fire UHF incident ground communications

Simple. By being programmed to tx and rx on the same frequency. Its not just the mobile tx but the base tx being used as simplex too.

RSM work in mysterious ways. You'll notice they don't list any Police frequencies at all. I wonder if this falls under the same sort of category - that its RSM approved (lets face it, Fire wouldn't go rogue on frequencies), and its just not published for privacy and security of communications?

Hi all,

I'm a bit confused as well.!

On the RSM website the frequencies assigned to Fire and Emergency New Zealand between 492.21875MHz and 497.19375MHz are shown as "Land Mobile - mobile transmit" and the repeater frequencies don't start until 498.800MHz. So how are the lower frequencies being used as "portable frequencies" for incident ground communications?

Cheers.

Grunter1.
