Ed,
No manufacturer has ever claimed that PCM would work alongside FM on
the same channel. I wouldn't jump to that conclusion based on one
test. In fact I wouldn't even entertain the notion that it might be
remotely possible.
The only reason I ever saw for using PCM receivers was the ability to
change out the transmitter battery while the airplane was in
flight. The PCM receiver - if no fail save settings have been
implemented - will hold the last settings when signal is lost. So if
the plane is trimmed for level flight you can shut down the
transmitter for a while without the plane going nuts.
Hope this helps
Rick

Jim Laurel,
I read your informal test of PCM vs. PPM on your JR radio. I have never heard
that you could avoid channel conflict by using a PCM receiver. Failsafe and,
perhaps faster or more solid signal handling were what I heard. Can anyone
confirm this ability of a PCM receiver to ignore a PPM signal on the same
channel? Could be a good reason for me to consider using PCM. I never had a
good reason before.
