[Elecraft] Confused

[Don Wilhelm]

Eric,

If you wound that yellow toroid, you updated the BFO.

The mod with the yellow toroid is no longer the current one (that is why you
can't find it) - the new BFO upgrade has a prewound toroid pre-wound with
very fine wire.  If you are considering the PLL stability mod, you should
also install this more stable BFO.  (The newest BFO design is included in
the post 3000 serial number kits - but the PLL stability mod is not).

If all you need is the documentation, I'm certain someone on the list can
find a file with the document - sorry, but I don't have one available.

73,

| OK, I lost it, I modified the BFO or PLL , somewhere in November 2002,

for
| L33.

site
