Each radio has a number of channels, each of which cover the same frequency bandwidth. If you set the channel number on each radio to be the same they should work fine.
Be aware, however, that if they are different models, the channel numbers may not start at the same number. Some will start at channel 0 while others may start at channel 1. Since the bandwidths for each frequency range are set the same, just need to set the channel on the radio with the higher number to one lower than on the other radio.
Hope that helps.

We no longer support the RFM radios. Once it dies then you will have to purchase a new radio.
BUT TRY THIS: OPEN PDLCONF.EXE WITH RADIO PACIFIC CREST CONNECT, SAVE TABLE FREQUENY (UPG),
AND, DESCONNECT, CONNECT OTHER RADIO, AND TRY IMPORT THIS UPG
