The PRO-92 is not like the PRO-93, PRO-95 or PRO-97. While the latest version (firmware ver 3.28) reads control channel data, you must still program in all frequencies of a trunked radio system. Actually the PRO-92 provides a means that none of the CC only scanners provide - you can lock out a FREQUENCY of a TRS.
So regardless of the firmware version, all frequencies should be programmed. The difference between the firmware versions has to do with how the scanner gets some of the data of a TRS.
