In the wav file is that white noise or data bursts before and after

Sounds like very weak packet bursts to me.

I looked at the sample with a waveform editor (Audacity) - there's
definitely data riding on the 100Hz tone, at around 5-10% of the 100Hz
deviation. It looks like it continues during the DTMF bursts also

Kevin,
Sorry to bother you again but where do you get these Toshiba S-AV15 modules?
I did a Google search and did not really find anything.
$49.95 at RF Parts.

to 100 at the other end, two
of those in parallel at the T gets you back to 50 to match the feedline.
Any number of receivers other than 'powers of 2' is more complicated. This
does nothing for the loss of course.

between the receiver and the duplexer? A 3db pad should reduce the
sensitivity by that amount, but if there's a severe mismatch the
sensitivity might stay the same or actually improve with the pad.

not sure, but my guess would be to use the same spacing as between the
elements on the individual antennas. With your varying dipole orientation
and distance from the tower you'll probably get an interesting pattern.

other length and anything other than an open or short requires calculation
for the exact length, frequency, and coax impedance to determine the

will transform the 50 ohms to 100 ohms. These 2 100 ohm points are T'd,
giving 50 ohms for the main feed.
The above seems easier than using the hard-to-find 35 ohm coax but there
must be other factors I haven't thought of that caused Decibel Products to
use it.

when I was and during the test, the alert lights were not illuminated. I
assume all radios would work the same but I can't say for sure. My radio is
a Radio Shack (Tech America brand), SAME capable.
