Perhaps it would be interesting to compile the inputs for the whole system?
On Mowat, the input for channel 597 (152.0) is channel 212 (149.2 if my math is right)in Zone 2, the input to 152.000 is 148.795; is it the same for Zone 1 (Mowat)?
Check.My head is starting to spin.
Range 1 starts at 138.015mhz/Channel 0 and stops at 139.995Mhz/Channel 132.
I get 149.995 for channel 265.Range 2 starts at 148.0150Mhz/Channel 133 and stops at 150.040Mhz/Channel 265.
I get 151.760 for channel 379.Range 3 starts at 150.065Mhz/Channel 266 and stops at 151.715Mhz/Channel 379.
I get 150.275 for channel 280.Excel shows 150.2300Mhz/Channel 280.
