I'll have to rerun the test to see.. I don't think real numbers were
put in as I was expecting to get an option for "MASTER"
I've since disabled that in the other software to use CORRECTLY as the
device provides gain versus some pseudo control which I don't know
what its doing..
I didn't get any movement at all in the signal on any of those gain
settings, but I also don't think I limited to 1-15 either..
I will retry since I've play'd with the other software to see what
settings seem to give the best SNR...
Of course, in the real world you'd tune the
gain(s) to find the best
SNR, which is typically the point just before the noise floor starts
rising appreciably.
Thats what is done, on the production unit. I admit to upping it a
little for rain fade, stray pine needles etc. for some fade margin.
Which does resolve those... I also use dedicated and professional LMR
antenna and cables, ie:LMR400, yagi at site etc.. I try to make up
with things at the antenna not at the other end.
I also use the constellation to get a good pattern and go from there.
With a good pattern there 99% of the time the rest will take of
itself. Mostly.
Now that I know the other is creating a fake setup, and what really
should be done I can test again.
Thanks.
