I found that the Plate detector performs very good with a low modulation source. Using my AM transmitter with the audio input low, there was no distortion with music or speech using the Plate detector.
Possibly when these radios were new, the transmitted modulation level was lower than what it is today?

The resistor is a 2.2 Meg, it was the last one I hadn't replaced. The broadcast is coming in after replacing it.osanders0311 — 09:09 PM |

What does the resistor measure? I think it should be 3.3 Meg.
