OT: CTCSS tones for repeaters

[Ken G Kopp]

GM guys!  Thanks for the "reality check" on the current situation as it
relates to the use of -output- CTCSS tones on amateur repeaters.  I can
certainly understand the advantages,
especially in intermod crud impacted areas.

One additional note. When repeaters send CTCSS tones, many
radios depend on the poor low frequency performance of small
speakers to suppress the audio tone. This approach fails when
using a car audio system to get enough volume to overcome wind
noise etc. Having a fairly steep rolloff below 300 Hz available
would help with this situation.

This should be easy with RXEQ. It's also good practice to roll off the
lows on FM TX for the same reason it's good on the HF bands. While the
lows don't burn more power with FM, they do use up deviation that would
better served by voice range, so the practical effect is the same.
