[R-390] FW: BFO Question on Newly Acquired R-390A

Hi Chuck,

Do yourself a favor and buy the set of Bristol wrenches made by Xcelite.
(Xcelite 99PS60 Series 99 Compact Bristol Multiple-Spline Socket Type
Screwdriver Set: 9 blades, extension, and handle- Amazon $44 bux!)

Long time ago I bought the Max-Gain set of "standard L keys" before I met up
with the nasty, tight, corroded,  hard to reach Bristol set screws. I found
that for most of my needs, I couldn't get the L keys where I wanted them
(too small for clumsy fingers), I couldn't apply the amount of torque needed
to loosen/tighten the set screw (too difficult and/or tiny to grip for the
"twist" needed), or the shaft was too short to be free of obstructions.

With the Xcelite set, you can pretty well eliminate all these issues.  Plus,
if you need a new or special Bristol (or allen, or Phillips or...) "blade",
you just buy the blade you need cause you already have the handle.  

To be fair, Max-Gain now carries handles for Bristol spline blades, but the
available lengths do not look to be as long as Xcelite blades based on what
I could find on the M-G site; and the handles...well, that's probably a push
but Xcelite does have that extension for when you need a really long reach
to a very stubborn set screw. ;-)

YMMV.

Happy twisting and 73,
Chris

No Amazon stock owned, no interest in Xcelite, and nothing but love for
Max-Gain

Craig, Foster, Charles, Phil, Don and Roger,

WOW, what a group, thank you!  I searched the Y2K doc but didn't find any
reference to adjusting the BFO frequency other than the standard +/- 3 KC.

Max-Gain Systems, just a couple of miles down the road has Bristol wrench
sets, so I'm off to see Alan Bond the owner to get a set.  I too would like
to know the specific Bristol size to make sure I get the right one.
