<DIV><SPAN class=796451320-01052007><FONT face=Arial size=2>I have a few
questions concerning packet radio.</FONT></SPAN></DIV>

<DIV><SPAN class=796451320-01052007><FONT face=Arial size=2>+ I think from
memory that packet does not simply use 1200 = high or 2200 =
low.</FONT></SPAN></DIV>

<DIV><SPAN class=796451320-01052007><FONT face=Arial size=2>+ Does it keep
flicking between tones to "keep the energy up" in the detector
?</FONT></SPAN></DIV>
<DIV><SPAN class=796451320-01052007><FONT face=Arial

<DIV><SPAN class=796451320-01052007><FONT face=Arial size=2>+ And a non flick is
a state change ?</FONT></SPAN></DIV>

<DIV><SPAN class=796451320-01052007><FONT face=Arial size=2>+ From what I have
been reading 0x7e or 011111110 is the start or txdelay ?</FONT></SPAN></DIV>

<DIV><SPAN class=796451320-01052007><FONT face=Arial size=2>+ What is the bit
stuffing i hear about ? why is that so ?</FONT></SPAN></DIV>

<DIV><SPAN class=796451320-01052007><FONT face=Arial size=2>+ I have noticed an
MX614 does tone changes at the zero point, what are the distanvantages then of
using xr2206 xr2211 that do not do this ?</FONT></SPAN></DIV>

<DIV><SPAN class=796451320-01052007><FONT face=Arial size=2>+ Does packet use a
CRC method ? is that what the passall command is in a tnc ? show now crc
chucksum valid packets ?</FONT></SPAN></DIV>

<DIV><SPAN class=796451320-01052007><FONT face=Arial size=2>+ From what I can
see on my bench testing, one cycle of 1200 Hz and two cycles of 2200 Hz fits
nicley into 1200 baud ? coincidence ? </FONT></SPAN></DIV>
