It's not the program. Most radios have a high-pass filter in the

No, most radios have a three-inch speaker that can't reproduce the
CTCSS tone. If you plug a hi-fi speaker into most radios, you'll hear
the CTCSS just fine.

No, don't think so. The CTCSS tones are 'sub-audible', that is, they are below
the range that humans can hear.

No, just on most radios, the low end is cut off by
filters and the crappy speaker. The tone on the Ohio
Turnpike troopers on 155.790 and 155.685 is one af about
a half dozen that can be easily heard around the Toledo
area. It's the "whine" in the background...

If you can't hear from 50-200hz, you have serious
problems...

No problem here, my ears are quite good. My point was that with most radios, whether
one uses a good speaker system or not, the tones won't be heard.

That being due to the high pass filter. If you are hearing them, then perhaps your
system is not really up to par, or there are other issues with the transmitting
system which you have no control over.
