Thanks for the advice Johnny.
This seems to be the best way to go for a first time builder like myself.

I know other experts will give you more advice. From my past experience, I
would build the basic K2 first. Since you have KSB2, there are some components
for KSB2 to be installed on the front panel, you can do that as well.
Once your basic K2 is ready and fine, you can start with the others.
I used to have a short birdie on my K3 on 28.004.00 after keyup, but now

Does anyone know how to get rid of this annoying birdie on 10 meters?

There is a huge amount of noise in our apartment building largely, I
believe, from the DSL Internet/Cable TV distribution network to 300+
apartments. 80 and 40 are completely useless, 20 is only slightly better.

The other big issue with operating from an apartment (or with neighbors
in general) is noise. You may be able to get your own apartment
relatively free of noise-makers, but don't count on the rest of the

Change the first occurrance of "on" in the paragraph below to "off" and

Your concern for getting the K-Line as good as it can be for cusotmers, and as
quickly as possible, is setting the standard>>> actually raising the standard
for all other manufacturers.

Ed,
You will have to make up your own mind on that question.
If you normally use the bands that usually have the preamp on, you would
probably want to set it with the preamp on.
However if most of your activity is on bands where you do not run the
preamp, set it with the preamp off.
Keep in
The calibration is a pseudo-standard or convention, i.e 50 uV at the
antenna input equals S9 on the meter. So it doesn't make much sense to
have the preamp on for the measurement. If you did, the only way to
compare two rigs would be to specify whether the preamp is on or off on
each rig. Not t
Hi Ed, I calibrate the S meter with the preamp off... that allows the gain of

find plenty of gain, that overpowers the filters with the
Hello K2 receiver wizards, what makes more sense when using the XG1 to set the

difference on 40mtr..I suppose most K2 owners turn pre-amp on from 20mtrs
and up, while turning it off 160-40 for better selectivity.

Jeremy,
From those resistance readings, I would say you are OK.
If you have all except Q7 and Q8 installed, do a TUNE and re-check the
voltage on the base solder pads of Q7 or Q8. If you do not see a
voltage between 6.2 and 6.4 volts, replace Q11 and Q13 and retest before
you install Q7 and Q
It depends on which side of Chicago you are talking. NW of Chicago there is a
big lode of iron which makes verticals work very well with few radials as they
do here on the Gulf Coast for DX. A 43 ft vertical is 5/8 wave on 20 meters
which will give it about 3 db gain over a 1/4 wave vertical w

Take a look at the web information about construction of "true Magnetic loop

I have one made from 1" (1.125" OD) copper pluming pipe and 45 degree elbows

Gary,
Have you tried Fixed Tune Mode? While Fixed Tune does not move MKR-A or
MKR-B, it does move the VFO-A marker (center) through the displayed spectrum
as you adjust the K3 VFO. This way the spectrum appears to stay stationary
while the VFO marker moves through it. You can also configure
So after reassembling everything minus Q7/8, resistance from ground to
collector pad for Q7/8 starts at 600k ohm then gradually drops down to 54k
ohm before reseting and spiking back up to 600k and dropping again. I
believe this would be a capacitor charging up and then biasing a transistor?

There is no indication on the cheap meter for an out of scale reading.
I've borrowed a Fluke meter from work, and after watching the capacitors
charge up, the resistance reading is 2.7k ohm. This is will all of the
resistors still connected as above. I'll reconnect them one by one and

Hi Gary,
It sounds like you're happy with just tuning with the VFO-A dial. Why bother
with the marker at all. Use of markers is really not all that convenient.
You can also use VFO-B as a pseudo marker. Pushing the K3 A/B button will
jump you to the VFO-B frequency. And VFO-B "can" be made to trac
Hi Wayne,
I'm not at home now so I won't be installing the beta firmware until later
this month. I use a vertical for 80 meter CW work and a loop for 75 meter

of selecting a different antenna within the same band by track

I have made good contacts with my homebrew Magnetic Loop Antenna on 10 and

In the most of the case indoor and QRP.

and my Youtube channel (look for PU23CLR and magnetic loop antenna).
