howdy,
after 20days works,i built my k2(4513#)and ksb2,knb2 and dsp option. it
works as a whole,but it clicks and pops while i tune the VFO,every 5khz.
I know it is because of the constrution of PLL/VFO, move VFO over 5khz,the
division ratio of PLL change and the reference osc and the varicap
While I'm usually in my office on Sunday afternoon/evening and miss the
nets, I'd like to point out that cdx are great on 80 for the western US
virtually every day this time of the year. With just a short (45 ft) doublet
fed with open wire line, I consistently work all the states west of the

Good Evening,
Conditions are conspiring against us but let's see what happens once
the RF hits the aether. First there is an X class flare zooming toward us
due to smack the ionosphere sometime tomorrow afternoon. The initial
effects allowed some interesting DX contacts to be made on 10 me
Hi Marinos,
Methinks that the Ostrich at 28.266 ( 28.276 in my K2/100 - and a BIG one)
could be one of the mixing products of the LO (PLL) and the BFO. Am thinking
about major surgery in an attempt to get rid of some or all of the many
internal spurii in K2, which can be a problem in single convers
Well I made it to the second alignment stage. I found that plugging the
headphones into the headphone jack and not the key jack works much better
for testing ;)
All tests passed with flying colors and the receiver perked right up using
my K2 on a dummy load for a signal source. I'm listening to
Paul,
Yes I have used Spectrum Lab with good success - it has many fine qualities.
I still prefer Spectrogram over Spectrum Lab for fiilter alignment, only
because Spectrogram's markers are vertical lines while Spectrum Lab uses
pointers on the baseline which I find harder to see at a glance.
hello, the sidetone is perfect.

Hi to all,
I know there was a recent discussion in the forum about this birdie singing
at the low end of the 10m band, but did not recall seeing any definitive way
to kill it.
In my case, I want to think of the birdie living in my K2/100 as a
substantially bigger one, a turkey (with the K2100 e

hello,
Using a general coverage receiver to listen to bfo and
vco, the bfo is stable. The VCO is stable on ssb but
the VCO clicks chirps and fm on cw.
Any suggestions?

I found that powering the K2 and the KPA100 separately causes the resistor
R13 in the KPA100 to get hot to the touch. When the power is removed from the
K2 and using power only to the KPA100, R13 runs cool. Maybe R13 was put
behind the fan for a reason. I believe it it best to run the K2/

There was a another suggestion made, that I've done. Cut a

solder a bit of wire for a key onto the shell of the female connector.

That was my suggestion, and it was only a post on the reflector, I did not

The details are as you recall - Pin 4 is not used, so that is the one to

piece of toothpick for example. I used

I seem to recall that somebody somewhere reported adding a safety measure
to the IO connector and the matching cable. It involved plugging one hole
