Greg,
Try the wide range first. If it turns out to tune too fast for you, it
is a relatively easy matter to swap the capacitor and the crystal for
the 30 meter band for the narrow range later.
Think of it as a 2 component change (only one if you do not have 30
meter coverage).
You may have

I set mine up for the narrow tuning range, but sometimes I wish I had the

I went with 80 khz, and the actual value ended up being 108 khz. Also being
a general class, when I was done with the K1 I changed the VFO range so that
the available frequencies were a closer match to what I am allowed to use.
For me it is working out well.

Great opinions. I have also been reading some stuff online about it. I
think the wide tuning into novice is beneficial, and if anything, I can do
what Don suggests and just switch out the cap if I can't seem to get along
with it.

Did you also replace Q11 and Q13?
The demise of the finals can be caused by excess bias voltage, so when
new finals are put in with no other checks or actions, the new finals
can be damaged quickly.
Make a quick check - measure the base voltage on Q7 or Q8 while doing a
quick TUNE - be

Does this gain control occur before or after the compressor if it

Might be more appropriate for a long decay gain control loop to

The Macos K3 utility works perfectly for me also on both my Macbook and
Macbook Pro (intel). The only thing you have to actually install on more
than one machine is the Prolific 2303 driver/kext for the USB-RS232

Sounds sweet to me, even if it is just number soup. As some have said,

Before anyone gets confused, you only need to install the Prolific
driver if you happen to be using a USB-Serial adapter with one of
their chips. I've had way too much trouble with them, so I don't. The
FTDI -based adapters work incredibly well...
The K3 Utility works very well for me also.

Kieth,
If you want to move only 40 meters, you must change the 40 meter crystal
on the 4 band board- you will have to find a fundamental mode crystal
that is 25 kHz higher than the one you have currently installed - most
likely a special order from a crystal manufacturer.
It is easier to move
One of the issues found in QSK operation is that TX-RX state changes
MUST modulated the received envelope. It is a fact that the RX stream
must be turned off, and then turned on, to support transmitting and
that is a modulation. The RX is ON after the latter state change and
will hear the

It is easier to move all 4 bands upward. Just spread the turns on L1 to

You will likely loose 30 meter coverage unless you change the crystal to

This is what I did.

In Logger32, I have configured the Setup bands modes CW options to read

You would connect the radiator to terminal A and the radials to terminal
B. If you want to connect to a ground (it is not necessary), then it
will connect to the GND terminal.
The NorCal doublet is a complete antenna for parallel transmission line,
and that has nothing to do with
