IDAS multizone scan

[SAFFA]

HI Guys.

I have a situation where I have two single site IDAS trunking systems. I need a Icom IDAS mobile that can scan both sites and be able to talk back.

1. is this possible on a IDAS radio
2. If so, which models will be able to do this.


Thanks

Likely not.
I don't use an IDAS trunked system, but I do run a NexEdge trunked system. While they have similarities, there are some differences. Mainly the dedicated control channel of NexEdge vs. the decentralized nature of IDAS. The trouble with trying to scan two trunked systems at the same time is that it would need to monitor both control channels simultaneously. With only one receiver in the radio, this would be impossible to do and not miss something. The packets sent out by the control channel are very sort, and the scan time of the radio is going to miss something.

Maybe there is some variation in the IDAS system that I'm overlooking.

I know that scanning a trunked system and a conventional system at the same time is not possible with the Kenwood NexEdge radios.

I'd love to hear if Icom mobiles/portables have some way of doing this.

The IDAS single site system is based on NXDN type D trunking which doesn't use a control channel. Kenwood have released there type D trunking compatible radios ( NX-220). I've managed to do it on the Kenwood by selecting "multi" under the scan settings and having each trunk system in separate zones.

I need to be able to do the same with Icom's though. If the icom can scan between zones in conventional then I'm sure it will work with trunk system too.

That's good to hear. I know the system will scan fine if you turn on a radio in the middle of a conversation, so that makes sense. I'd be concerned about depending on it hearing traffic between two systems. On the public safety side we try to limit scanning due to how easily important traffic can be missed. Good to hear it'll scan between systems. I guess in a way that's kind of like roaming...
