  F [minRSSI] : Scan and report RSSI for full set of channels
  L [list]    : List of freqs of interest (LH for help)
  R           : Read RSSI for current channel (RL for 'L' freqs)
  O           : Continuous RSSI display (OL for 'L' freqs)
  U / D       : Change tuned frequency up/down by one MHz
  B / C       : Increment band/channel on tuned-frequency code

  =           : Set or show button mode value
  V           : Show program-version information
  I           : Show frequency-table information
  H or ?      : Show help information

 Extra commands:
  XJ [min,max] : Set or show RSSI-scaling values
  XJ default   : Set RSSI-scaling values to defaults
  XA [0|1|R]   : Disable/enable/restart auto RSSI calib
  XM [minRSSI] : Set or show minimum RSSI for scans
  XI [seconds] : Set or show monitor-mode interval
  XU [text]    : Set or show Unit-ID string
  XR or ~      : Read and show RSSI (with channel info)
  XB / XC      : Decrement band/channel on tuned-freq code
  XP           : Show all frequency-list presets
  XL [name]    : Show frequency list for preset name
  XZ           : Perform soft program reboot
  X, XH or X?  : Show extra help information

 Frequency-list command:
  L [list]    : Set list of freq (MHz) values of interest
  L           : Show list of freq (MHz) values of interest
  L 0         : Clear list of freq values of interest
  L +values   : Add values to current list
  L -values   : Remove values from current list
  L S         : Load list of freqs via RSSI scan
  L H         : Show help information for 'L' command
     When a list is entered, the frequencies in the list will be the only ones scanned and selected by the 'A', 'S', 'N', 'P' and 'M' commands.  The 'RL' and 'OL' commands will scan and display RSSI values for the frequencies in the list.  Entering 'L 0' will clear the list.  The '+' and '-' operators may be used to add and remove frequencies, and may be mixed together (i.e., 'L +5740 -5905').
     The 'L S' command will load the list with the frequency set returned by the last scan ('S' command), or will perform a scan and load the detected values.
     Frequency-list-preset names may also be used as parameters to the 'L' command (i.e., 'L IMD5').  Available presets may be displayed via the 'XP' command.

Automatic RSSI Calibration
     By default, the acquired raw-RSSI values are automatically calibrated so the reported RSSI values are in the range 0 (no signal) to 100 (maximum-strength signal).  Once the receiver has been tuned for the first time to a strong signal, the calibration should be in place.  The calibration-scaling values may be viewed via the 'XJ' command.  Fixed calibration values may be set manually by disabling the automatic calibration ("XA 0") and entering min/max values using the 'XJ' command.  Entering the command "XA R" will reset the calibration-scaling values (same as "XJ defaults"), restart the automatic calibration, and display calibration-status messages during the rest of session.  (The "XA S" command will also enable the display of calibration-status messages.)

Debug/Test Commands:
  G           : Show raw debug inputs values
  E [0|1|txt] : Serial echo on|off or echo text (to slave receiver)
  XD [chars]  : Show given chars on display
  XX [list]   : Show index values for frequencies (devel)
  XK          : Show frequency table values (devel)


Keyboard Shortcuts:

  Cursor Up/Down    : Change tuned frequency up/down by one MHz
  Cursor Right/Left : Auto-scan and tune to next/previous channel
  Home              : Scan and report channels with highest RSSI
  End               : Auto-scan and monitor channels
  <Enter>           : Repeat last command (if R, N, P, B, C or G)
