Multiple MDC codes in one radio

[Firemedic449]

Hello, I have an issue when programming my radios for the departments I am with,
So I have a HT1250 UHF radio and I have programmed 2 zones in it, one for my volunteer dept. and one for my job. I have 2 different unit numbers and I am trying to program the radio to where depending on what zone im in it will transmit the proper MDC, Thus far MDC-1 seems to work fine, but when I switch to zone 2 and transmit I hear the noise MDC makes but on the receiving radio it wont display the MDC nor will the radio im transmitting from display a MDC when I transmit from a separate radio that works fine. Anyone have any ideas?

Is it actually transmitting MDC, or are you just hearing the sidetone?

I guess I'm just hearing the side tone, but I haven't been able to find any information on if a 1250 can support multiple MDC, as in encode and decode.

Did you create a second MDC system and a new personality to go with it?

You can't use the same personalty with multiple MDC IDs, but you can have multiple personalities, each with a different MDC ID.

It also works better if you don't try to assign the same personality to multiple zones. And it's easier to manage multiple scan lists, too.

They are the same channel but listed as like so...
Ops 1 z1
Ops 2 z1
Ops 3 z1
Ops 1 z2
Ops 2 z2
Ops 3 z2
So the channels have the same frequency and pl , MDC 1 is assigned to zone 1 and MDC 2 is assigned to zone 2, but only MDC 1 will display the ID on the receiving radio [cdm1250] and only MDC 1 will display a ID on the ht1250 when it receives a transmission

You can not assign multiple MDC IDs to a single personality.

Do this:

Ops 1a z1 MDC1
Ops 2a z1 MDC1
Ops 3a z1 MDC1
Ops 1b z2 MDC2
Ops 2b z2 MDC2
Ops 3b z2 MDC2

Ops 1a and 1b are identical personalities except they have different MDC IDs assigned to each and each personality is assigned to a different zone.

On the receive side of the personalities, unless you have separate Call Lists for each zone, you can just assign MDC1 to everything since that simply makes the personality display received MDC IDs. If you have separate Call lists, then assign the MDC systems separately based on zone.

Ive tried making duplicate personalities with separate MDC , dont know what else it could be, but is it possible for radio to handle this task?
