<DIV><FONT face=Arial>I don't know about the synth module compatibility.
That is probably a frequency shift direction issue. I have a six meter 9Z
and long ago I bought a DAD PPM receiver made by FMA and they had to do a major
mod to it to make it work with the 9Z. As I recall, if you look at the
output of the discriminator you get the familiar series of control pulses going
from zero to some voltage for about 300 microseconds with spacing of 1 to two
milliseconds depending on stick position. But then there is a long period,
like seven milliseconds used to sync the decoder. On most systems the
voltage would be low, like the period between the pulses but with the 9Z
transmitter the signal would be high like the peaks of the pulses.</FONT></DIV>
<DIV><FONT face=Arial>My Berg, that came directly from Peter, worked and I don't
recall telling him anything about the 9Z other than what channel it was
on. I assumed it figured out all the polarities and did what it needed to
do. I can't say why it wouldn't work with the synthesizer.</FONT></DIV>

<DIV><FONT face=Arial>I'm pretty sure it won't work. The sync pulse is
the wrong polarity with respect to the servo position pulses in the
9Z. Just inverting it won't work. I can't imagine why they did
that. Interestingly enough, the Berg receiver figured it
out.</FONT></DIV>

Expert Electronics' F650 (Horizon part number EXRR6501) with Futaba or
Hitec transmitter(s)?</SPAN></DIV>
<DIV dir=ltr align=left><SPAN class=640104020-31012007>This is JR
