Audio muting / pilot tone issue with Lectrosonic LR


Actual visual sound

Recommended Posts

There are a few operational reasons why the receiver doesn't recognize pilot tone:

1. The compat mode has changed. Make sure the same compat mode is selected in the transmitter and receiver. The default for standard US product would be "NU Hybrid". 

2. If your system is in the A1 frequency band, there may be a mismatch of pilot tone frequencies if you are operating on a frequency between 486.400 and 495.600 MHz. This frequency range is common to both Block 470 and Block 19, so both the transmitter and receiver have to be on the same frequency AND the same block. 

3. If your transmitter audio gain is set far too low, the receiver can squelch (mute audio) even at normal distances. Your audio gain should be set on the transmitter so that peaks in the audio trigger the -20 modulation LED to blink red briefly.
