i did a lot of measurements due to low sensitivity on 20meter with
trackinggenerator and spectrumanalyser the real max peak of the 20meter
bandpass filter is at lower frequency (abt 13 MHz) if you align the
filter for max gain on 14 Mhz the peak ist abt 6db lower as on 13MHz i

Hello everybody,
Kevin, KD5ONS , posted a note saying that I had copied K1EV during the 0200Z
40m ECN last Sunday / Monday. Yes I had under S9 PIGGISH propagation
conditions - also W4STK. What Kevin did NOT say , as I think that he is too
modest , was that he too was making it over here again -
Most fishing tackle stores sell fishing rod blanks for those who build
their own rods...Long blanks can be a challenge to transport...Fishing
rod ferrules in a wide variety of sizes, and ferrule cement can be bought
at these tackle stores and the blank can be cut and ferruled...They also
sell surf
Take a look at the Moxon Antenna page for sources of cheap rods.

So I am going to try to pick up a capacitor locally. I am confused by the
value.
If I understand it correctly, the manual says caps marked with two digits
are the value in pf. Three digits markings use the third as a mutliplier.
The manual says its either 27 or 271. In this case wouldnt 27 be
Hi Everyone,
I am trying to repair an Autek WM-1 meter that was hit by lighting. The
lighting came through the ground return of the coax. It seemed to damage the
power supply to the board that does all the work. Nothing else seems damaged
except the soot and a few traces were burned off.
Would think the marking for a 27pF capacitor of 271 in the K2 manual may be
an error when compared to the markings for similar values. For example: C43
on the RF board, 33pF is marked 330. The usual notation of this type of
capacitors is the first two digits are the first part of the value
There is a mistake on the parts list page of Appendix A, RF Section for
C198. You will notice that the caps above and below list 20 (or 200) and 33
(or 330) but somehow C198 is 27 (or 271) - WRONG! Should be 27 (or 270).
As I remember, when I built mine it was marked with a 27.
Rich,

While tuning up my K2 filters with spectrogram and tuning the bandpass
filters, I decided to see how the transmitted CW sounded on my K2 Rev B
with keying mod, temperature compensated oscillator mod, and KAT1 tuner,
so I drug out my 75S-3B receiver to listen as I tuned up into my dummy
load.
But, I need to find an LM7805 in the small wee package the
comes with the K2s. I have been to Mouse and all they have
is the TO-220 at 1A.
Search for 78L05 and you'll find plenty of them at Mouser and Digikey.

Lee,
Mouser has them - the designation is '78L05' for the low power package and
'7805' for the 1 amp version. Similar numbering is used for the low
power/high power versions of most all the 78xx 3 terminal voltage
regulators.
With that generalization out of the way, Mouser's part number is
Hi Carl, ( everybody else)
I too love my K1. (#1337) It has a funny story behind it too. I had just
moved into my (Oops, our.) new QTH and to battle the needs of my newfound CW

Thanks a million for setting me straight on the lm78l05 in the TO-92 case.
I've had so many wonderfull people contact me. Thanks a million. I'll try
Radio Shack...and the I will see where to go from there.

Hi All,
These are both assembled, aligned and tested Elecraft KFL1-2 two band filter
boards for use with the Elecraft K1 QRP CW transceiver. One has been built
for 15m and 30m use and the other for 20m and 40m use.
Either can be easily modified for use on 80m, 40m, 30m, 20m, 15m or 17m by

Hello,
My K-2 audio sometimes fades completely away. It can happen whether I'm in RX or
TX mode. (Yes, the sidetone can fade to faint or no signal.)
Sometimes the audio comes back up almost to the original level, sometimes even
all the way back. But it fades again before too long. And it happens

of a KX1 look like. Note: I always do a complete inventory before stating any
