we meet there. 20m skip is OK between us
but day is short, 5 days ago 0 hours here.
So, skip time is between 08-15.

I have polar- and auroral attenuation.

I followed the suggestion to align the K2-filters (my K2 is CW only) using
Spectrogram (website N0SS). A real nice advice, going from filter to filter I
now don't need to retune. Thanks a lot.
As for the suggestion to use Spectrogran for adjusting L34 too, I tried it but
I still prefer using an
Hello all,
Check out the Legend of the Pulpit Rock Polar Bear.
I'm sure you'll enjoy the legend and learn something too.
So look up into the nighttime sky on January 14th at the full moon
and hit the transmit key! We bears will be waiting to hear from you.
Look for WA3WSJ, WB3AAL and N7UN/2
Hi Don,
I removed, checked, cleaned and reinserted T6 and T7. I also did a visual
check for bad joints around Q21.
I also did a side by side comparison with my FT-897 while listening in to a
LSB QSO on 40m. The same antenna was used and I switched between radios
using a BW switch. Without

The K2 does not need the preamp on 40 meters.
Ron D'Eau Claire wrote ion the list in Nov of 2004 how to determine when
the preamp is used on the K2. I quote from his post:
The purpose of the preamp is to improve the noise figure on the
higher-frequency bands, not to make the

I just had my first opportunity to use the K2/100 on a
fairly large antenna for 80m (inverted L with total
wire length around 150 ft., through a low-pass type of
antenna tuner). I noticed a few fairly strong
intermodulation products from AM (medium wave)
broadcast stations on and around 80m.
Steve,
Since these are likely products of the K2 mixing scheme rather than 'real
signals', comparison with another receiver that does not use the same mixing
scheme as the K2 will not necessarily produce the same results - but your
comparison with the Drake should confirm that they are indeed
This circuit may help you evaluate your KNB2.

I used 1.8 megohm fixed for the base resistance. With 5V input, output
is about 4V.
Varying C1 from 470pf thru .047uf varies the pulse width from approx. 10
uS to 500 uS.

If you really can't hear them on a different receiver, check the bias
voltage on the t/r switch. It should be between 90 and 150v.

If you really can't hear them on a different receiver, check
the bias voltage on the t/r switch. It should be between 90
and 150v. Low voltage here can cause this problem. The t/r
switch is used whether or not the KPA100 is activated.

It certainly sounds as if your more recent plans represent a rather
