[R-390] BFO Bellows

[Tisha Hayes]

Usually a cracked bellows does not bode well for the BFO in general. They
do not like being over rotated and if someone was cranking away on it they
likely damaged it internally.

You could put a frequency counter on the BFO output and see if it is
anywhere near 455 KHz. I bet it is not.

Generally they show up on auction sites and probably most people on the
list have a few extras. I would think that you could get a replacement in
that $20 US range (not that I have one to sell).

The front panel knob has a keyway that should prevent you from just
spinning away at the BFO. If the knob was not put on to be nearly flush
with the front panel or the keyway is missing you can end up with a BFO
adjustment that just turns and turns. (bad thing).

When pulling the IF deck this is one of those things that you should set to
the zero position and use a dab of paint or fingernail polish on the IF
deck so you know where to put things back together at.

that success or failure in competitive activities exhibits no tendency to
be commensurate with innate capacity, but that a considerable element of
the unpredictable must invariably be taken into account." -- George Orwell
