Its that time of year again. The weather is getting cold and it's time to
build another kit.
I have K2/100, serial number 5439 for sale. I built this rig in late spring
and summer of this year. It is in new condition. I have been building kits
for 30+ years including several from Elecraft.
Thanks so much Don and Ron for the quick fix!

I think Don's observations sound like the problem I
and a few others have had. See, for example the
symptoms described here:

I've come across some braided Dacron line for raising wire antennas at a
very good price. It's really kite line. Kitebuilders.com has 1640 ft roll
of 200 pound test for only $25.00. that's less than .02 per foot, not bad
!!. A bought a roll, this much line will probably last me forever. It
Have you any thoughts about what might be causing Don's K2/100 to behave
when he switches the display from RF to ALC? I can see how the ALC might
'hunt' on SSB, but switching the display should not make any difference to
ALC action I would have thought.

Steve,
Thanks Steve.. I was hoping there was something I could do.
Do you (or anyone) have the details of the necessary resistor changes?

It's even better than Rich indicated. Just visited the site, and the price is
now $23. Not really shown on the web page, but apparently the second spool is
only $15. I ordered two 1640 foot spools in different colors for total of $38.
Should last me till I die and then some!- Thanks
While tracking down a low power output after installing the KXB3080
into the
KX1, I was checking the voltages at Q1, Q4, Q5, Q6, and Q7 during transmit into
a dummy load. Page E-6 of the KX1 manual states there should be 0.7VDC at the
base of Q7 during transmit with a KXB30 (not KXB3080)
I have been using a Kenwood MC80 with my K2. I use batteries, but I have
been told that the mic. will power with 5 volts. The mic. does have a
gain/level control that can be used to dial in the right level.

I'm wondering how many other Elecrafters will be in the CW SS contest this

Elecraft rig, power level, antennas, and your section.
I'm planning on the entire 24 hours here from Colorado using my K2 at 5W in
QRP division.

There is no change in the base circuit of Q7 - that is true whether the
KXB30 or the KXB3080 is installed. You should be tracking down the source
of the negative voltage at Q7 during transmit.
Yes, the voltage at the base of Q7 should be about 0.7 volts during transmit

Hi Craig:
I've NEVER (in 45+ years of SSing) been able to make it thru the
entire SS without rest... and I'm sure this year'll be no exception.
That having been said, I do intend to operate QRP single op and will
try to work as many folks as I can... I've found that, when using
QRP, it's

We've finally posted the results for the 2006 Elecraft QSO Party (EQP)
on our web page. :-)

See you all in EQP 2007!

Realizing certain pitfalls, can someone tell me what typle of bulb I can put in
series between a dc source and a 7 ah gell cell to maintain a charge on it...I
have more gell cells than proper chargers, and my thought was to get them up to
full charge with a real charger and then use the series
Hi
Maybe I can help. Gel cells should not be allowed to discharge below 10
volts and charged above 14.5 volts or damage may result. If you want to
maintain a float charge on the battery you should set the power supply to
13.8 volts and limit the current to about 1/3 of the rated amp hour of
Well, I will be in the contest, but not with the K2 and not running QRP.
Sorry, but the OLD Flatland Amateur Radio Transmitting Society will be running
all out at W0NO's QTH. Now, I would take the K2 but when you are invited to
play...you play with his toys. Lots of fun with a good antenna
After years of putting up with a touchy K1 tuning pot, I finally put in a
metal-shaft replacement. The new one felt great, but was tuning backwards
(duh) so I switched the leads, put the cabinet together, and now the VFO
doesn't tune at all.
The LCD indicates I'm at the bottom end of the band
I get consistent power measurement results using a Fluke DMM and Elecraft DL
1 and an o'scope connected to the DL 1. I triple check with a calibrated HP
signal generator checked against my KX 1 attenuated to match the HP
generator. I am pretty confident in my measurements.
I have received many
Ever since I hard reset my K2, it doesn't behave the same way in CW.
Thanks to Don, Ron and Dave, I have fixed a few things.
I use an iMac so I bought iSpectrum from Dog Park Software in order
to more accurately set XFIL, etc. I find documentation of this
program particularly lacking.
Sorry to hear it's such a tedious procedure, John. And (sitting here at my
windoz machine) I can't help with iSpectrum.
However, your plight underscores something you can do to protect yourself in
the future - something few have probably done (or kept current).
That is to write down all your
Folks,
For those who do wish to record the menu settings (everyone should), I
recommend that you download the K2ATOBKT manual from the Elecraft website
www.elecraft.com and print pages 3 and 4.
Those sheets provide a convenient list of all the menu settings you would
need if some disaster (like
John,
Condolances on your misfortune.
I do Windows here, so I can't help much, but I did look at the screenshot
for iSpectrum on the web and it looks like it could do the job for you. The
waterfall display seems to include a spectrum display, so what you need to
do is determine the frequency
Someone recently posted a problem similar to this. Of course I didn't
pay attention to the answer!
I recently changed the configuration of my station to connect an antenna
directly to the ANT 2 output of the KAT100. Previously, it was
connected through an automatic switching system,
So now I am about to put the KI02 RS-232 I/O Option into my K2.
Now I want to work CW from the computer using serial port
control line keying. That should be simple, but what
circuit/components are you guys using to do that?
Any links were I can read about it?
Please tell me so I don't mess
You can look at the pinout for LPT1 at

Don,
Yes, you are correct. Lifting one end of R28, Q7 still had a negative
voltage at its base during transmit. I'll change out Q7.
I'd like confirmation weather the KX1 circuit diagram on page 18 of the
KBX3080 manual is correct or not. It shows Q7's base connecting to R2, a
1Kohm resistor.
Thanks Joe!
That's simple enough. Just about right for my level! :-)
Is there any reason in practice to use optic coupling versus direct keying?
I'm going to use it for a K2 and never ever going to upgrade to K2/100
or using an amplifier.
