Sorry I don't have one, but my Elmer W1LHY did in 1955. I wondered, how did it come to be? Aha, an engineer designed it! I will be an?engineer! And I did! First job out of school was National.? 73 Richard N1AA

... but I have a NC-125 and I am having trouble getting the Pitch Control (BFO) to work.

If anyone has one (NC125)? I'd ask you to pull the plastic knob & measure the resistance from chassis ground to the brass shaft and report here or email me at w8rmv at arrl dot net.
As I look at the construction, it looks like the brass shaft should be at or near ground level.

Coil L18 is supposed to be center tapped, but my 125's also has significantly more resistance on one side than the other.? Maybe I have a bad L18.

Still searching for an answer, as the rest of the NC125 works great!
