So hang time is not available for a digital channel? I thought it was, as well as SIT, especially since the help file for SIT says to make sure SIT is set at least as long as hang time, but preferably longer. I'll have to look at this more closely.
Thanks.

SIT vs Hang Time
When a Trbo repeater is operating in digital mode, what exactly is the difference between traditional hang time and SIT (Subscriber Inactivity Timer)? Based on the description in the CPS, SIT sounds merely like a second hang timer.

Two considerations from years of experience deploying temporary systems on a weekly basis: 1) Larger diameter coax (RG213, RG214, 9913, 9913F7, LMR400[-UF]) tends to hold up better, if for no other reason than it tends to command a greater psychological respect from users. 2) Coax of any type in thi...

If height is at a premium (two 7dB fiberglass antennas will be about 14' before separation), a half wavelength should be fine, a little more than 1 foot in the low 450's, but...
