London Bus change over to DMR

Post by Metradio » 04 Nov 2018, 14:02

Testing of the London Bus DMR Network has started. From where I live I am receiving DMR in the clear from them on 139.66875MHz, this has been receivable for the last 3 weeks or so. Eventualy the system will be encrypted.
Their current MPT1327 and the new DMR Tier III system use the frequencies between 139.500 and 140.500MHz..

Does this testing and upcoming change explain why I can now hear drivers on the 1to1 calls? In the past I could only hear the controller during 1to1 calls but on on group calls I could hear all drivers on the route. Now I can hear both sides all the time.

I'm rather disappointed, I can't hear the new DMR system still

From Slough I can only pick up the one frequency, but a listener East of London has reported three live DMR frequencies from his location..
Might be worth a search of their band looking for the DMR beacon..
