Malcolm,
The system is currently 4 channel system. With 18 talk groups and probably 200 users. Our users range from taxi companies to ambulance service (the taxi services are very heavy users). Reciever antenna height is 700’. I have used IDA, Zetron, Trident and your controller Idylltek.
We were using IDA’s but trunk times were slow some times taking 2 or three tries. Goto or Trunk off of home channel was even slower, it would fail once out of 5 tries. We fought this problem for years. The weird thing about the IDA’s was that we had problems with certain ID’s that would not work even if you opened all the ID’s on the system.
Tech support was not very helpful, heck I had to explain to them how their alarm circuit worked and why it was a pointless feature, if it keeps the repeater keyed up permanently and [you] have to drive to the site to physically turn the controller off and back on.
The Zetron and Trident are good controllers but software to program them is not very user friendly and trunk time is slow. Our new controller, your LT8R has been working great. I could not believe how fast it trunked, and you can’t tell any more when you are trunk off your home channel. The audio is super, sounds like your talking simplex.
Our system is loaded pretty heavy during peak hours. Just because we need to add in the other channels, but it won’t be a problem with the controller, just pop in another board.
