I think this RR.com user above is asking about the Channel ID's for a standard BEE00 Motorola 800 mhz Phase II TDMA system. Usually by default for any Motorola 800 mhz Phase I and Phase II systems is Channel ID's 1 thru 4 only. If I am wrong please let me know. Maybe Union City Channel ID's are in-correct possibly. Here are the Channel ID's by default.
ID SLOT SPACING TX OFFSET BASE
1 1 6.25 - 45.0 851.00625
2 1 6.25 + 30.0 762.00625
3 2 12.5 - 45.0 851.01250
4 2 12.5 + 30.0 762.00625
------------------------------------------------------------------------------------------------------------------------------------------------------------
When I was looking at Union City the Channel ID's seem a bit off. Not sure if this is typo or if this is actually really correct.
