Bob, while I have not done it with a PIC processor, I am sending data
between two processors.  I started with an inexpensive transceiver from Hope
Electronics (www.hoperf.com) and used their HM-TR.  It was easy to use, but
what they did not tell me was that it could only send 32 bytes every 20ms or
so.  I had previously tried the Linx TRM-916-ES and RXM-916-ES which is a
transmitter and receiver pair without any luck.  I just got another set this
week and milled the proper PCB as they describe in the data sheet for each
unit and it works like a charm.  No data limit, no delay time.  They quote a
max rate of 56kbs. Range is quoted at 1000ft outside, 500' inside.  I have
yet to verify that with the flat grounded line planar antenna I am using.

Bottom line - the HM-TR is easy to use - it comes on its own PCB that you
just plug in - as long as you can live with the 32 bytes every 20 ms.  The
Linx is faster, no string length, but takes PCB magic to make it work,
Hope this helps.

Subject: [PIC] UART and Wireless TX

Is it possible to use the UART on a 16F88 for wireless transmission to
another PIC? I am currently using a transmission routine from the Pic IN
Practice book. It works OK but I would like to simplify the process. I am
sending the result of an 8 bit ADC conversion to another PIC to control an
SPI Digi Pot.                        
                                            Thank
                                            Bob
