<font face="Comic Sans MS">It used to be that in radio control you
picked a frequency for your transmitter and for your receiver.
There were channels on 6 meters and at 72 and 75 MHz. You depended
on being the sole user of a frequency to guarantee that you were
in control. Back then you would tie a ribbon to your antenna
which told every one which channel you were on so no one would
accidentally jam your signal and cause you to lose control</font>.<br>
<br>
These days the frequency used has has changed to 2.4 gig. You turn
on your receiver and your transmitter and Bind them. The
Transmitter handshakes with the receiver and they create a unique
link. Everyone using the field can use the same band and the radios
don't interfere with each other.<br>
<br>
There has been some threads on this reflector about spread spectrum
(ha, an understatement for sure!) and recently been some talk on
syncing signals. I wonder if folks here have looked at what is
happening with modern RC radios? BTW as I understand it these new
transmitters have flash-able bios and considerable programing
capability so there is a possibility of re purposing the gizmo.<br>
