[Milsurplus] Wilcox CW3 BFO problem

[Ian Wilson]

Why does that ALWAYS happen? There are coarse and fine frequency adjustments
accessible from the top of the BFO coil. Breathed on the coarse adjust and
got vicious heterodyne squeals. I was looking at the voltage on the BFO
cathode, was too small to see with hum on top of it.

So it's all working now. I notice that although it's a "CW" receiver, the
6dB bandwidth is about 4kHz.
