No, I can't explain it. 16665 is the magic number used in the PX-777
to indicate no tone. Here's an example:

struct {
          rx_freq: 4:[(15390000)]
          tx_freq: 4:[(15390000)]
          rx_tone: 2:[(16665)]
          tx_tone: 2:[(16665)]
     _3_unknown_1: 0x02
     _2_unknown_1: 0x03 (......11b)
       power_high: 0x01 (.......1b)
           iswide: 0x01 (.......1b)
             skip: 0x01 (.......1b)
             bclo: 0x00 (......00b)
     _2_unknown_2: 0x01 (.......1b)
      _4_unknown1: 0x7F (.1111111b)
            pttid: 0x01 (.......1b)
          unknown: 0xFF
} memory (16 bytes at 0x0590)

struct {
             name: 6:[0x19,0x0C,0x0F,0x12,0x1B,0x0E]
              pad: 2:[0xFF,0x00]
} names (8 bytes at 0x0B18)
