Youre confusing levels and deviation! I always strive for the deviation
limiter at 5khz,use a 1khz tone at 3khz deviation in and out and CTCSS at
.5khz out.They dont add up together like you think they would,so 3.6 is not
what to shoot for,do them separately!You can get fancy and plot the response
at 100hz increments all the way to 5khz to see any non-linearity in your
audio path. The results may surprise you!
DONT transmit into your service monitor's antenna port! I use a couple of
rubber duckies on the monitor and dont connect it to anything.
For folks who dont have duplex service monitors,take a handheld,send touch
tone 5,measure what the deviation is,switch to the repeater output and
adjust it to the same level. Good luck...
