Frankly, signal strength means little to me. The "copy-ability" of a

Hello all,

Jerry,
You will still want to remove the front panel to check the wiring of the
microphone configuration header.
It must be wired to match your chosen microphone.
Since you did not build that K2, you may not know how to get to the
Front Panel.
There are disassembly instructions at
Just for yuks, I opened it up to seewhat if the SSB adapter had been
installed,
and somebody pulled it out?
Sure enough, C167 was tacked messily to the top of the board.
According to the
schematic, you remove that when you install the SSB adapter.
That's good news. It means I just
Hi Don,
I do have the original manual. I also found a quick reference card.
Printed it out in color, double sided, cut it down to size, and
laminated
it.

Many filters constructed using the newer crystals do not have that tilt,
especially at narrow filter widths.
Wide filter widths do have both tilt and passband ripple.
Having aligned almost 2000 K2s, I can say this with certainty.

Jerry,
Look at the crystals again - if they are marked 4.9136-S they are the
new ones.

Yes, those are the older crystals. The new ones have a "-S" suffix on
the label.

The passband of the filter has a tilt (the SSB module's filter is much better)
When you switch between CW and CWR, the slope of the filter reverses with
respect to the base band, so it sounds different. It's not that unusual for
other rigs to do this to a lesser degree. Of course where the

You will quickly get used to the UI. If you do not have a manual,
download one from Elecraft.
As another 'helper' one of my friends who was just getting used to the
K2 created a chart of all buttons with their functions as well as the
menu. You can download that chart from my website

Hello all,
My new ( to me ) K2 arrived yesterday, far in advance of when Ebay
said it would. Color me happy :). I just ordered the SSB adapter.
My first impressions: The UI is a little cryptic - a general weakness
of things with small displays and few knobs/switches/buttons, but
12 matches
