Hi John,
I was looking for a tuner that could be adapted for use at the
antenna end. Recently I purchased an LDG Z-11ProII, but I haven't tried
it yet. There is information on the LDG website on a modification to
install an internal battery pack for remote use. After it arrived I
opened
feedpoint, then the LDG or other similar tuners are the best choice.

Rapid cooling of the screw may also help. You don't need to go out and
buy some freeze spray if you have a can of dry air aerosol dust remover.
Turn the can upside down, using an extender tip that often comes with
contact cleaner or aerosol lubricants, and try to limit the spray to the
screw.
While I'm at it, here are a couple of tricks used by aviation mechanics.
Using a good screwdriver tip, dip it spark plug cleaner abrasive, then
try it on the screwhead.
OK, so you don't keep a stock of spark plug cleaner abrasive, another

It works fine would be a matter of opinion, not the result of bench

I'm just finishing my KSB2 board, and I did encounter this problem at
only one hole, the cathode for D1. Otherwise it all went together as
per the instruction, and a bonus, somehow I ended up with a few
unexpected spare parts, such as a 2N3906, two extra 2.2mfd caps, and a
couple of resistors.
Thanks for all the replies,
that settles it for me, as I haven't enjoyed my own experiences
with DSP, I'll order the KAF2. And I'll consider the anti-ringing

My K2 is near completion, minus the options, which haven't been ordered

much appreciate some help with them.
The big one would be whether to add on the traditional audio filter or
the DSP instead. I'd like to keep current draw

That's good therapy all by itself.

for whatever spacing tool you

from the board, then the LCD will not fit correctly, and you may have

I spent almost 2 hours looking for the missing pieces, without

While assembling my new K2, I've lost some of the LED backlight

I don't see where the LED backlight spacers are used, are they? If
so I should order a replacement.
