Nope, no varying the pulse width on the TX.
I figure it would have to be VERY SLOW serial data because the update rate of the TX/RX RF combo is around 50hz, so therefore, the serial data rate has to be AT LEAST 1/2 of that, if not less to keep the error rate down. The PIC at the RX end would be sampling the pulse width, changing the output bit according to the pulse width. I can't change the output bit any faster than the RF will send the new pulse width, hence the name of the thread.

And since that 50hz might not always be 100% constant and might shift around somewhat, that's why I figure I have to go with, like I said, at the very most 25hz. Something probably more like 12hz would probably work just fine. There would still be a lot of edge slewing, but it might still work.
Again, I don't know how accurate that 50hz update rate actually is. Won't know until I actually try it out on an actual R/C system.
