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
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!
