That is interesting as I was told you could assign up to 20 scan lists to one TSYS but you could not assign a scan list to more than one TSYS. I just wrote a V File for northern Nevada with all the counties except for Lincoln and Clark. Because I wrote it under the assumption that I could not assign a single scan list to more than one TSYS or trunking system, I had to duplicate a lot of talkgroups. When I first tried to load the program I got a warning message that I had exceeded the memory capacity of of a single V File. I had to do some serious weeding out in the talkgroups. So I didn't' put any Las Vegas talkgroups in the site I chose for White Pine County where I would think some Las Vegas units could occasionally travel and use those talkgroups. I chose one EDACS site per county, the one that I guessed would provide the widest coverage for that county if I was traveling there.
With Motorola systems you can duplicate scan lists and assign multiple scan lists to one site, but you can't assign one scan list to multiple sites in a SmartZone system. But armed with scan lists duplicated for each site, the radio will switch to the site it is receiving best, just like the SmartZone trunking operates. I haven't traveled with the PSR-600 mobile yet to try it out.
By the way, it was Don Starr of Starrsoft Software, who told everyone on the thread for his Win500 software about not being able to assign one scan list to multiple sites, those being EDACS or Motorola. He did indicate, as I said, that you can assign multiple scan lists to one EDACS or Motorola site or system as some call it.
I have programmed my PSR-600 mobile with quite a few of the sites in the Southern California Edison SmartZone system. In the V Files for different portions of southern California I've programmed a TSYS for the most prominent or wide coverage site. I have a scan list for every talk group I know of in the system and another scan list for the talkgroups that are used for the local area my V File covers.
When I write a V File I can't start writing talkgroups for a TSYS that has the same scan list. I can duplicate another scan list and perhaps give it the same scan list number as I did for another TSYS but this creates a duplicate set of objects and reduces the memory of the radio by the number of talkgroups in the duplicated list. I'm not sure this works as the scan list would not be able to distinguish which TSYS to use in the trunking. If it somehow works by pooling all the TSYS system frequencies at once how does it keep track of the LCN? If you program two sites that have duplicate frequencies and the sites are not part of a simulcast group of sites, how does that work?
I'm confused and what you have said contradicts what I've been told about this radio. I need to grab some dinner and read the manual again!
