4. Reconnaissance and Surveillance Leader Course LOS Fixed Frequency Operation Up to 100 nets can be programmed into the radio. Net names consist of 12 alphanumeric characters. –Spaces not allowed. –Default names for each net is NET##, where ## represents a number 00 to 99. Each net can be enabled or disabled during programming at the ACTIVATE IN LIST? Prompt. –Choosing NO makes net inaccessible with PRE+/- button. It is callable by entering the channel number. Type of net must be selected before the net is programmed: –LOS Fixed Frequency Net –Dedicated UHF SATCOM Net –Frequency Hopping Net, SINCGARS or HAVE QUICK AN/PRC-117F Net Programming Considerations
