No need to do, Bart,
They have forgotten to put the errata into the kit. This happened first time
and I got an alarm message immediate from Elecraft to add it to my stock
kits. Normaly the erratas are in the kit.
'Normally' being the key word here. Apparently they can't keep up at the

I experienced the 50Hz warble on received signals when I used the 25A power
supply on my newly-built K2. I constructed a 3A-supply using the Linear
Technology LT1085 and, most importantly, a toriod transformer. The supply
can
be stood on top of the K2 without any problems. I've since
Thanks to Don and Ron or their responses and everyone else also.
I used my scope with the 10x probes and measured the peak to peak
reading from a tee connection going to the dummy load. Squared that and
divided by 400 to get the power out, can't get too more accurate than
that. Now the K2

Many thanks to Randy N4TVC for his help in getting my second-hand
K2 on the air. Last night I was able to get the K2 and a K1EL K40

for me to have my first call a QRP contact with Norfolk Island!

Tim,
That certainly sounds like a bad solder connection or an unsoldered one to me.
Look in the BFO area first if it effects the filter passband, otherwise the VCO
area is another possible candidate for suspicion. Yes, even in something that
has been working for almost 6 years, an unsoldered
Earlier I had stated my KAT100-1 was displaying random SWR LEDs on 30 meters.
My antenna is a Carolina Windom 80 with approximately 70 feet of RG8X coming
off the bottom of the lower balun to the shack. (There is an additional 22
feet from lower balun to the off-set center conductor.) A
Ken,
Congratulations!
I always enjoy the first QSO with a rig just built as one of the finest.
I hope you will continue to enjoy your KX1 as much as I enjoy mine.

Roy,
That goes to prove once again that my feedline tunes may antenna due to
the transformer effects of the feedline length.
The major problem with a multi-band antenna is finding a feedline length
that provides an adequate match for the tuner on all bands - but I wonder
just how high the SWR is
Can someone suggest a kit using SMT components that would be a good
learning experience for someone wanting to learn SMT techniques? I
would prefer something useful like test equipment rather than YACQR (Yet

make some nice high performance Microwave kits, these
Don makes an excellent point. RG8X is supposed to be very low loss cable,
but it's still 50 ohm transmission line and all low-impedance lines have
relatively high losses at high SWRs.
My data shows that RG8X has a loss of 1.0 dB/100 feet at 10 MHz when
properly matched. That's quite good, and

Similar and probably more affordable are kits from Down East Microwave.
Don't let the microwave part fool you as he has kits that start as low
as 50 MHz. I've built several of the transverters from DEM which all
had SMT components.
I'm pretty sure that some of the kits from Kanga USA are

Hey gang:
I'm just finishing the build of a KAT2 for a friend.
Manual says it takes 1.05 or better to gain all features
of the tuner. My friend tells me he has 1.04D in his rig.
My question:
What feature will he not have using 1.04D ??
Thanks a bunch:

Hi Vic, I'm with Joe on this one! I've just built two of these, one for the
K2 and the other for the K1, First time I've attemped a SMT Kit Very pleased
with the results, If you do go with the K1 CW ind' order the replacment
button works great! check it here
If all you want to do at this point is practice sending, you can
download the program CWCom from http://www.mrx.com.au/d_cwcom.htm.
You connect the paddle to the computer via two pins on a serial port.

Hi Chas
Thank you for your interesting info.
I was surprised that you mention using 400w on PSK31
I've never seen anyone mention using more than about 70w on PSK31 as
high powers are not supposed to be necessary?
Just my comment as when I experimentally tuned up my Acom 1010 amp
for 400w
I've finally gotten around to updating my batteries page to reflect my
experiences with my new-found love, Lithium-Polymer batteries:

Comments, suggestions experiences of other outdoor QRP ops are most
welcome.

The KA7EXM Digital Power meter will go a long way to getting you fully baptized
in SMT. Plus you
will get a very useful piece of test equipment. It is available from Kanga.

While I was at Ozarkcon 2006 in April, I saw a demo of SMT soldering

I have done both the N0SS Version of the K6XX CW tuning indicator as well as
the KD1JV Digital Dial/Frequency Counter. Both are good starting projects for
SMT as they don't have a large parts count. The N0SS instructions for the CW

The drop will still be quite low... lower than a single silicon diode,

There appears to be very little power on the high bands (less than a watt

Bob,
The output should not fall off that drastically on the higher bands. Expect
a minimum of 10 watts on 10 meters.
I suggest that you check the value of each and every component in the
transmitter amplifier chain (those components on sheet 4 of the K2
schematic). Check all of them for proper
There is also a capacitor in the 10dB amplifier after the driver, and it
is on the bottom of the RF board and sometimes overlooked. If you leave
it off, the ALC will be able to pump up gain in later stages but output
on the higher bands will fall off. Just check to make sure it is

Truth be told, one can work the world using 5 watts (or less) on CW too,
Actually it is not difficult to measure the SWR (or impedance) of an antenna
at its feedpoint.
Remember that an electrical half wave transmission line repeats the
impedance at the far end, so I keep a half wave of RG-8x for many bands
especially for this purpose (the number of bands grows as I add
