This unit is licensed as a radio control system.  The transmitter must be
type accepted and hacking on it voids this.  R/C systems may not be used to
transmit any message other than for the operation of devices at remote
locations.  In this case, the receiver turns on a tone generator.  No voice,
telegraphy, etc. may be used.  FCC Part 95.212 also prohibits transmitting
data:
       "Tone or other signal encoding, however, is not considered to be data
	when only used either for the purpose of identifying the specific
	device among multiple devices that the operator intends to turn on/off,
	or the specific sensor among multiple sensors intended to turn on/off
	indicating device for the operator."

Your alphanumeric paging application is definitely illegal under R/C rules.
It would also be illegal under CB rules since the only no-voice transmission
permitted under CB rules is limited to selective calling of tone-operated
squelch tones to establish of continue voice communications.
