I read in another post that LTR is "dead". I find that interesting, as there is several LTR systems in the Knoxville, TN area.

I've never fully understood why people will make blanket statements like that. LTR is alive and well. You can still purchase LTR equipment.
Many companies will run it until there is no possible way to get parts/support/radios, etc. That's just the way things go for many.
Sure, it's been "replaced" by newer technologies.
By the way, I'm still waiting for the flying car that many predicted we'd all have by the year 2000.
Yepper, LTR is very much alive and well for at least another few years. Though the issue with LTR SMR's is this: Most LTR SMR's are owned and run by an service provider that is also an radio dealer. This means they are "powered" by the primary corporate entity that they sell. If they run Motorola, then they are going to be pressured to move onto the newest tech, that makes it an easy upgrade from the LTR to digital. In Motorola's case, that is MotoTRBO. Hence the quickly accelerating upgrades to having at first, an LTR, and TRBO system side by side. Then the eventual offline of the LTR as they push the subscribers over to upgrade. With iCOM shops, the push is to NexEDGE, and same as with TRBO/LTR, side by side, then full NXDN. Both formats are very, very much similar to LTR, but with the advantages of digital. Though in my book, DMR (TRBO), is the real winner as it offers TDMA upscalable expansions as that tech improves. I mean, you win with 2 Chan's/TG's as compared to one with each freq. (2 Slot TDMA DMR)
And in the future, that will expand to 4, and eventually 6. But for the sole user LTR's,... They will be around far longer than the SMR ones as they are not pushed hard on an daily basis to "step up to the future".
when you have a wide and high area to cover like the Pocono Mountains its most active area for LTR easy to switch from tower to tower and its more of a money maker for the radio shops..My service we have two repeater sites we utilize and have decent service.
To be honest not sure why other dont use LTR more and the only other problem is when radios need to be upgraded everyone is pushing DMR..
NXDN has had an attempt to do that type of "pair gain" for two talk-paths within a 12.5 kHz channelspace. I've seen a few 3.125 kHz offset from center frequency license applications, and it was a big enough deal several years ago for the FCC to issue a Report and Order on it. And then, that seemed to die down. Seems to me, though, that the R&O was biased, in that they required NXDN implementers to be FB8 on certain frequencies - only - for the two talk-paths (actually two separate repeaters with isolators and combiners), and DMR has no such restrictions (yet seems to be more problematic, especially since it's been allowed on non-paired VHF).
I never thought about it that way, looking at the vendor sales angle, but I would suppose that if you have a captive audience, you might want to change-out the platform so they would buy the latest and greatest. It's done with other products all the time. The advantage LTR has is that it was released into the public domain by E.F. Johnson. Otherwise it really would have been dead a long time ago, and it's versatile enough to be band agnostic. I suppose it's the Linux of two-way.
