The alignment tone is strong enough to pierce whatever roadblock there is, not so real radio signals.
Andrea,
But I was thinking if the radio was 30dB down then 30dB lower tones might be noticed. But I have never tried.. Some form of signal tracing might help, a scope or diode probe. I think troubleshooting suggests a lower value for R43 for the early stages.
Late 2017, but it developed this issue only very recently.
