72Mhz is back


Lets get one thing perfectly clear. If we had any money, this would be a stock 9 channel transmitter & stock 9 channel receiver, with 9 servo wires going into the ground station where they would be converted to autopilot functions & resent by a 2.4Ghz full duplex XBee. No soldering. No PPM decoding. That would be a truly untethered plug N play system.

Google searches for 9 channel radios R ugly. Ubama's RC stimulus bill looks better every day.

The binary to PPM modulation from last year works again & the link is sending binary from the transmitter directly to the laptop for the first time.

To use a 72Mhz transmitter, U can't capture any analog signals. Previously got good results by moving the antenna away from the transmitter, but analog readings drifted slightly & we now need very stable analog readings for autopilot commands. Decoding PPM is much easier, but not as accurate & fast as direct analog readings were.
