Talkgroups can be strapped to phase 2 exclusively, or dynamically switch, depending on what radios are affiliated and registered on that TG. It's all in how the fleet mapping is done.I'm pretty upset about this fast upgrade path as a Cobb Taxpayer as well. Just seems too soon. My question is which users are going to go TDMA exclusive and which might stay FDMA for the foreseeable future. I believe you can run both on what they are moving to. I'm also curious if anybody is hearing encryption rumblings, Cobb has traditionally been pretty open listening except for MCS/SWAT.
Does that sound like the best use of that money to you?The $13.3 million is only going to be used to replace the infrastructure at existing tower sites and some equipment in the 911 Center. This money will not be used to replace existing subscriber radios used by the County, cities, private ambulance services and other users of the radio system, nor does it pay for any additional tower sites needed to improve portable coverage throughout the county.
Actually, RobertsRadio's (who's always right on the money) comment would seem to indicate that our current Phase I P25 scanners should be fine for most of the comms we listen to as portables/mobiles aren't being replaced en masse...the hundreds of XTS/XTL radios installed that work perfectly well don't do TDMA anyways, those who monitor the large county fleets should be ok for the the foreseeable future.Means you have to upgrade to the PSR 800!
and the source of this speculation of yours is from where?yes it is expected to happen with the 3rd or 4th Quarter of 2014...according to some sources i have..why the push for TDMA PII...and MCS/SWAT are open most of the time...they only encrypt if its a very bad situation...but thats all the info i have right now at this time..but i guess they want to keep the listeners out like our public utility going to TETRA...that was a good move..Could have went P25 or NXDN or TRBO like Sawnee EMC did...but no control over anything..they have the money they will spend it in some way...
the Harris Unity is more expensive than an APX anyday of the week. And good luck getting a demo of one.To respond about other vendors' radios, the Johnson is still only DUAL BAND. I'd want to push for the Harris Unity, or the seldom-mentioned Datron Guardian II - both of which "get all the channels", and would probably be cheaper than the APX's which, at best, are only dual band. UHF should not be left out in the cold just because some schmuck thinks it's "the security guard band". They want interoperability, they need to "be about it", not just talk about it.
