My fau paux! It is setting the Modulator bias. The manual says 40ma. I usually have to dial it down a bit, or REALLY run the audio gain down a good bit.
Both my BC-610 and my T-213 put 400W out on pure carrier. So I have to keep from "letting the horse run!". I didn't know what the "actual" PEP out was until I bought the peak reading Bird. It was a Holy Sh** moment! I was a pumping 2500W PEP! I *knew* without question that it was going to draw attention, no matter how clean the signal was! So like those that run Commercial Broadcast Transmitters, I have to run herd over both of them. This Fall makes 30 yrs of being licensed. I got the AM bug when I bid on the Club's HT-37/SX-101A/with a Shure-737A. I kept that setup until the late '80s. I let it go to a school for their science class. It took tears before I found another Shure-737A. I didn't give a big hunk for it. Now I see that these 1954 animals are going for around $350! They are interesting on the inside. There is an actual large crystal that has gold plating on both sides, anchored on one end, while the diaphragm is attached to a lever that flexes the crystal. I sure hope the school got its use out of the old station!
