Any thoughts will be appreciated. Thanks for the help.
A while back, I reported this on the KSB2. Allthough some reactions
suggested I must have put in the resistor packs tilted, I'm certain they
are straight. Also, some other people reported the chokes *are* a tight

Geoff and all,
The real problem is that the insulation on the wire can be scraped during
the process of winding RFC1 and 2 (not during the process of mounting them
between the smooth surface of the R-Pak and the crystal body) - so just
being careful and re-wind if the wire is scraped is the
Having never used a wrist strap or anti-static mat before. I'm at a loss
as to the proper hook up these items. Does the wrist strap attach to the

Don and all,
Forgive me, I am guilty of thinking out aloud on the Reflector! My chokes
went in with care, and had snug windings. I did rewind one after visual
inspection and before installation, because I was a little suspicious of the
wire's enamel in one area and did not want to be faced with

lack of drive, making the 100w PA less efficient. Are these measurements
made on a dummy load or the antenna? Is a tuner involved? Were the PA

For ESD prevention, it is sufficient that everything in the vicinity of your

grounded is best). Hence, the Elecraft manual instructions 'Touch a large

K2 Serial number 4768 has arrived in VP8 (Falkland Islands). Inventory
completed and building to start shortly. I've got the K2 KPA, SSB, NB,

I want to publicly thank Lisa Jones at Elecraft for her efforts in

Fraser,
Not a mod, but an alignment may have been overlooked.
The K2 bandpass filter is shared between 160 and 80 meters, so it often must
be adjusted to a compromise setting to balance between the two bands.
Adjust the bandpass filter for a peak on 160 meters, and then adjust it for
a peak on 80
G'day,
And it lives about 60 metres east of #1400.
Now about this strong signal handling business.!

Fraser,
Just checked my K2/100 setup. For 100w it draws 20Amps, so something is wrong.
I would check the KPA100 160m low pass filter components. If you have access to
an antenna analyser such as a MFJ then use that with the dummy load.
If not use a signal generator along with your scope.

Going through the bands my own K2/100 (#4368) draws between approx. 15-19A
at full power setting, (circa 100W o/p). The club rig draws between approx.
16-20A in the same test, but on topband the current consumption is 27A !!
When typing same test do you mean with same antennas and other
Sorry I should have said that the tests were into a 50R dummy load. Thanks

Stewart - thanks - worth shecking the LPF components.

Thanks Philip, I will check the current of the base K2. The PA is in the
same box. No tuner involved. I would expect lack of drive would result in
low output and hence current? I don't understand your point re the pa
screws, surely that would cause overheating of the transistors on all
Oops, I should have said thanks to Gary too - his reply somehow ended up in
the wrong folder here.
The LPF and components around T1 T2 seem to be the place to look.

I was going to buy the LDZ's microtuner. However the ad and reviews indicate
that that tuner would stop at a 1;1.5 SWR OR EVEN 2:1.
The new external elekraft did promise true 1:1 SWR.

I use my K2 on CW and SSB. I was wondering how K2 Hams would feel about

For $89 the SSB board certainly gives you the most bang for the buck.

I am working on a true RF proc. I may have to buy a second SSB

Not quite. It will find the best match that it can, instead of stopping
when it gets close enough. That doesn't mean it will always give you
1:1.

Never heard of Oxy-batt electrolite
I thaught POLYmerized Lithium ion had the highest Watt-Hr/mass ratio.
I have seen laptop batts that are 72watt-hour @14V. The individual cells
are 1.5X the thickness of an AA batt.
I was able to fit a 60watt-Hr 14V batt inside a K2.
I had a few idea's for adding some circuits/other filters on a k2 SSB board.
Old or not 100% functional ok. I do not want to mess around with my original

It is adjusted just right...for my taste anyway.
