After setting L30 for 6v at R30 at 4 MHz, I am reading 1.53V at 3.5 MHz.
While this is above the 1.5V limit, is it a little bit too close for comfort
or is it OK? The voltages for the other band edges are all well within the
specified range.
Also, when adjusting the filter BFO values I found
To supplement Lee's email, I would say that ALC is a way to protect the PA
from overdrive.
For example, if I set proper ALC level at my ICPW-1 to get only 500 watts
(the full output of PW-1 is 1 kw), even when I turn the RF power control on
my IC756pro2 to full scale, the ALC feedback voltage
The VCO voltage reading is within the tolerances quoted by Elecraft so is
normal.
However this is not the whole story as you have to look at the results for
all bands rather than just this one and ensure that they also fall within the
stated limits. On my K2 on 40m with 80m set as advised

Hi Mike:
I happened to find the K2 amplifier keying circuit
partial mod kit on Elecraft's site. The write up

together a small PCB for this circuit. Do you have
any of the PCB's available for sale? If so, can you
email me the details?

Hi David:
They're for ANYONE, but primarily for Elecraft Owners, QRP or OTHERWISE! At
least the US-based Elecraft CW Nets are, and I'd suspect that the Eurasian

Use whatever you have... QRP or otherwise... just QNI (check in)...!

Hi
The K60XV option has the external amplifier keying circuit built in although it
uses a 2N7000 as the output transistor so it will not handle a large current. I
would guess the 2N7000 could be replaced with a IRF830 or IRL620 like in the
KPA100 if you needed up to one amp and 200 volts. The

i read all the posts about how well capacity hats work so i decided to
build one for my 8 foot whip.
i used a SO-239 (UHF Female) back shell (UG-106/U) to attach it.
i took a 9 inch pie pan and drilled a hole in the center and used the UG-106
to make the vertical to horizontal attachment.

I had the same problem as you. However, the K2 was GREAT on the air. I
finally traced the problem to the fact that both were using the same power
supply (cured most of it) and to much transmit power - used a dummy load for
both the K2 and the 706 with the K2 at about 1 watt. As my XYL is a ham I
Hi all: I am just nearing completion of the 100W upgrade to my K2. I am
unable to get the 1/4 4-40 pan head screws to reach far enough through the
board to catch the threads in the heat sink UNLESS I leave off the lock
washers. Without the lockwashers, everything seems to fit perfectly.
I'd
Hisashi,
It sounds like the K2 may be too close to the power supply. Try putting
the PS 1-2 feet from the K2 and see if that takes care of the problem.

Brian,
Something is wrong - 1/4 inch screws should be plenty long - dumb question,
are you really using the 1/4 inch screws? - they are NOT the black ones.
The only thing the screw should pass through is the lockwasher and the
transistor (yes the thermal pad too) before it hits the heatsink.

I don't know if I have a problem or not. I have made several CW
contacts with my newly built K2 during the past week. Most of them, the

Hello,
Just worked Ed, WA3WSJ, on 7040.1 MHz @ 20:47 UTC.
He is at Eagles Nest Shelter on the AT near Hamburg, PA in Berks County.
He will be here for a while until he goes to 20 meters.

You may have better results with a dipole antenna, or at least you will be
able to tell if it is the band.
A very low antenna as you describe, 12 ft., radiates mostly straight up and
is only good within your state except for exceptional propagation
conditions.

Hi,
I recently sold my Yaesu FT-897 because my K2 replace it for sure... :-)
