Dave,
NYCOMCO is still in the process of updating all the mobiles from the MDX to the M7100 first due to the NEXTEL agreement. Then they are going to reband Graham and Arden. Then they are linking Beacon, Arden and Graham as part of the interop agreement with Orange County. Certain talkgroups (Sheriff, 911 Polling, Intersyste,, etc.) will be broadcasted off all three sites.
I was told this was going to happen months ago as well, but nothing has changed other than the switch to the M7100's.
They are suppossedly linking the sites through the OC microwave backbone up on Schunnemunk, but their being hush-hush about it. According to one of their salesmen, he said if an agency (other than the county) wants their talkgroup off multiple sites, they will have to request it and obviously pay for it, which I find strange since they are using the county's microwave to do it. I asked if radios were going to affiliate between sites, if the end user had to manually select sites, if the sites were going to be voted and simulcasted and he looked at me like I had two heads. Salesmen aren't technicians, so he couldn't answer alot of questions.
But as far as the reband...still status quo.
