Why
Using balanced audio in a broadcast environment, I have on rare occasions
experienced issues with cross-talk between long runs of un-shielded balanced
audio lines. (inductive pickup??) I always wondered if the wires were truly
balanced when that happened.
I prefer to used shielded balanced
At the multi-FM broadcast transmitter site I work at ALL my network wiring is
shielded cat5 or shielded cat6. I have never experienced some of the strange
networking problems related to interference that I occasionally hear others
complain about.
At my studio I had a problem a couple years ago
I think when I made the original post it was late I was tired!!
I work in broadcasting and use the 111C coils often in long analog audio runs
for remote broadcasts. I do agree that transformers would be better than
active balanced devices.
The active devices are easier to deal with for short

What frequency was channel 7 digital and frequency channel 7
as
Channel 15-1.
The nice map also shows where the transmitter is located and a engineering
SWAG as to the signal level to expect.

You're partially correct. It certainly is true to two different PL tones each
deviating at 300Hz are going to generate a combined deviation of about 700-750
hz (because there will be some third order/mixing entered into it also).
In my situation, I used 2 Comm-Spec TS-32 boards. One board was

Most of the new ham radios support at least encode CTCSS.
Anyone still using an old radio that does not have CTCSS encode needs
to upgrade or get it installed.

On my two meter repeater we used to require one PL tone for repeater access
and a different PL tone for DTMF commands (including autopatch access).
The repeater generated the normal PL tone for repeater access.

Don't analog TV receivers us an IF of 45 MHz?
About 15 years ago I lived in an apartment where I had a 29.6 Mhz Mocom 70
remote base and a LPB series 330watt Motrac base on 52.525 MHz operating from
a Utility room about 200 feet away. Both were connected by DC remotes to
myself and another ham
That's not right, TV channel 14 is 470-476 Mhz.

Digital Channel 7 may NOT be the same as Analog Channel 7. It is the
frequency they are using that can be different.
