I'll get 'em!Thanks for those. Can you submit to the DB?
The mandate for 800 MHZ was to REband....not NARROWband. Although they are being somewhat narrowbanded to make some room, there is not mandate from the FCC, only to shift down 15MHz to make room for Nextel.I don't believe there is a narrow band mandate for 800, it's for VHF high and UHF only. Rebanding of 800 Mhz trunk systems refers to the deal made with Nextel (now Sprint) to swap frequencies to deal with Nextel repeaters causing interference with 800 Mhz public safety systems.
Both the pre- and post-rebanding trunked system control channels are programmed into the user radios (the actual voice channels in use are assigned from a table in the radio memory by the control data when a call is established).How does one of the cut overs work? The portable and mobile radios have been reprogrammed. Does that mean the portables and mobile radios are now operating on the new frequencies? I understand that the switchover will be later this month.
On a newer scanner, once the new control channels have been programmed, yes.Thank you for your reply.
On trunked systems, when it comes to the scanner, it will continue to operate with the old frequencies until the switchover? Once the switch is done, I will stop hearing anything from the old.
Yes; the user equipment transmitter tracks the same way as the receiver.On the user radios, if they have been reprogramed, are they transmitting on the new frequencies?
