Re: RFM12 with picbasic_pro
The datasheet for the RFM22 reads sensitivity of -121dBm. So line of sight range of 3000ft should be possible. Similar modules from Linx has a typical receiver sensitivity of -112 dBm. Baud rate also can effect range. Higher baud rates normally decrease range.

Re: RFM12 with picbasic_pro
The choice of antenna makes a huge difference as well. My RFM22s are 916MHz and I'm using a tiny little antenna (here). I've only tested to about 30 meters but under awful conditions (through trees and several walls). That was also after setting the transmit power low enough to comply with the U.S. FCC requirements.
