Question:
Why am I seeing a signal strength value of -99 on my 36M/72M module?

Answer:
A signal value of -99 on your 36M or 72M module indicates that the module is not receiving any valid signal from the 18R or 18R2 controller. This typically happens for one of the following reasons:

  1. The module is not synced to the 18R2:
    If the 36M or 72M module has not been properly synced with the 18R2 controller, it will be unable to communicate, leading to the display of the -99 signal value. Ensure that the module is successfully synced to the 18R2 by following the syncing procedure.

  2. The 18R2 is powered off:
    When the 18R2 controller is powered off, the module cannot receive any signal, and as a result, the module will display -99. Ensure that the 18R2 is powered on and in range to avoid this signal error.

Additional Troubleshooting Steps:

  • Check Distance: Ensure that the 36M/72M module is within the effective range of the 18R2 (1500ft line of sight). Being too far apart may lead to a loss of signal.
  • Verify Antenna Connection: Ensure that the antenna on both the 18R2 and the module is securely connected and not obstructed.
  • Environmental Interference: Large metal objects, concrete walls, or other devices operating in the same frequency range could interfere with signal transmission. Try moving to a different location or reducing interference.

If the issue persists after checking these factors, consider re-syncing the module or contacting our support team for further assistance.
