Hi folks -
This reflector has never failed me in 6 years! What a great group. Anyway -
I did get a reply with just what I needed and bought it - so thanks again for
the help everyone.

After many months, this thread rears its ugly head again :-)
At the time, I said that I would take a crack at updating "Your Novice Accent"
and collecting resources for the new ham who is trying to get proficient at CW.
I decided, after a while, that updating YNA was something I didn't want to

I have been trying to seek information about the relative merits of using
the T1 vs the KAT2 antenna tuners with the K2. For some reason, my request

Same exact problem here too. I tried, gently, this and that, and then
everything. Eventually, in spite of careful efforts, I had kind of
stripped the first few threads. I finally just wound it on there,
making some "new " threads. Wish I had tried a different nut, but I
didn't think of it.
Hi, Steve!
It's very important that you set the scan memory Start/Stop boundaries
as described in the manual. Operating without having done this is
pretty unpredictable, and can cause some of the problems you are
experiencing.

Bill,
If you look at the schematic, you should discover that the LPF area will
indicate DC continuity to ground. The secondary winding of T4 connects the
input of the LPF to ground for DC.
Since the K2 was working before, you have only a single failure point -
keeping that in mind while troubles
Gordon,
During operation of the K2, the reference oscillator is not used except as
the oscillator for the microprocessor - so there will be no observed effect
from changing the C22 setting.
During the calibration steps (for an accurate CAL FCTR reading, and before
running CAL PLL or CAL FIL), the
Michael,
Others have given you good suggestions, but ...
In most cases, you can simply leave the nut off - the BNC is securely
soldered to the RF Board and the rear panel is securely fastened with its
screws. The only thing the nut accomplishes is to cover the gap between the
rear panel and the
I had exactly the same problem. I tried for a long time and gave
up. I got a nut from another BNC connector in the junk box and it
went on right away. Something is not right with those nuts.
A recommendation for all new builders: try it before you install the
antenna jack. It is probab
Mike,
Mine went on first time..here is a tip you might wish to
try(having first checked that you have not, by accident got the right
nut confused with another on your bench). Offer up the nut to the threads on
the antenna connector. Then turn it anti clockwise until you feel
At first I thought the post was about me. :-)
I recall the nut going on mine just fine. The nut is small and easy to
get cross threaded and with plastic threads, it's easy to get things
fouled up.
My *guess* is that the nut itself has messed up threads. If so, the
more you try, the more likely
next clue : i pulled the outputs, which are not shorted and the set acts ok ,
that leads me to believe that I got a lowpass filter issue
especially since I get almost dead short at the output of the
finals/ input to the LP filters,,

Gee--I don't remember it as being particularly difficult. Is there some
flaw in the threads of either the nut or the connector? Is it the
correct size nut?

Hi Elecrafter's
When I built my K2 #2746 4 years back now I set C22 near enough using an
external frequency counter, then last year I added the SSB board, I noted
that I was about 200 Hz high as I do not work near band edges I left it at
that, but recently decided I would get it a bit nearer h

I answered David and apparently did not click on "Reply All." A long time
ago using the Elecraft Keying Circuit, I simply replaced the 2N keying
transistor with a MPSA42 which can handle max 300V (Vce) at 100 mA. It
worked fine with my SB-220 which has ~110V on the key line.

David,
Best solution: Change the output transistor to a mosfet device which will be
capable of handling the higher voltage. See the .pdf from Tom Hammond's
website - http://www.n0ss.net/k2_basic_8r_line_t-r_adapter.pdf for the
re-designed output device (HEXFET). It will require changing one of th
Congratulations!!!
I know the feeling. I went in to re-establish my ham roots of 30 y
ago and decided to take tech thru extra exams. Didn't expect pass
the Extra but studied very hard and passed.
Nothing better, eh?
You've done a great thing. I'm sure everyone on the group wishes you
Maybe you can key a TIP31 or 32 Power transistor from output of K2 circuit.
These worked pretty well for me back in VIC20/RTTY days for keying FT101E.
