Looking for a stock assembled Elecraft KX1 (without the tuner, 30 meter
module or paddles, just the plain KX1). Anyone have one for sale please let
me now the particulars such as condition, age, serial number and most of all
your price to include Priority Mail shipping to zip 45324.
Thanks

Martin,
On paper it would not be too difficult to build an IF crystal ladder
filter for the K2 whose stopband attenuation is an honest 100db or better,
with a passband ripple of something less than 0.5db - probably less than
0.25db. But the filter would require good quality high Q crystals,
Martin,
Bad mistake! The mixer that is mentioned in my last paragraph is a TUF-1 of
course, not a TUF-3. Sorry about that, cannot type!

There are some blue resistors that sometimes need an ohmmeter
check to verify their values. Seems the color bands on a
blue background can sometimes be hard to read. I checked every
one as I went to be sure I had the correct value.
It is most useful during debug, as you guessed.
Good
Hello,
I am a fairly new builder. I have been doing some soldering on
and off for about a year. I managed my way through a NorCal

Right now I am working on a T1 ATU kit. I am at the
Hi Guys,
Just wondering if this is normal behavior: I have my K2 set up with my DL1
dummy load. With output set to 5 watts, when I hold tune I sometimes get
about 4.6 and sometimes 5 - 5.something and sometimes 6 to 6. something.
This happens on all bands and at various power settings. Is it

That is normal. The power control ALC is not active during TUNE in order to
allow you to tune a manual antenna transmatch without causing the power to
fluctuate wildly with changes in the load impedance as you tune.
If you check the keydown level you will see more consistent power levels.
Have a rat shack mike with only 2 wires , an audio and ground wire.
According to mic schematic the on / off switch is parallel to the audio and
the on / off is a slide switch inside the mic.
Currently have the mic audio to pin 1 and mic ground to pins 7 and 8 at the
mic connector. I know in

Glenn,
I would suggest wiring the mic configuration header straight across for all
pins to be used - use the little computer type jumpers.
Wire the mic plug with your PTT switch between pin 2 and ground (use pin
7) - AF to pin 1 and AF Return to pin 7.

You should see 100 watts on ALL bands so, yes, those are down. Are you
making a minimum of 10 watts out on all bands with the KPA100 disabled?
I don't have a KAT100 myself, so I won't speculate on what might have caused
your original issue beyond the obvious observation that, apparently, it

John,
I've seen those symptoms when the XV power out was adjusted to 20
watts at the high end of the band. The K2 28MHz band has a bandwidth
of 800KHz. If the XV 20 watt power is adjusted at a frequency much
over that 800KHz bandwidth, the K2 isn't really putting out the full
1mw so the XVpower

I received mine today in USPS.
I finished the mods to the KX1 board and they are easy straight forward. I
have begun the KXB3080 board, but not installed.
Hope to be done tomorrow.
Stay tuned for further developmentsBurl, AJ9Q

Well as it turns out, my current draw is high. About 2.48 according to the
K2 display. This was at around 8 watts (2:00 position) on the band I
checked. But all bands appear to be around that 2.45-2.5 range.
I checked the finals to make sure there is no short to ground and they did
not.
Also, just noticed the book says the CAL CUR should be set for 3.5A. Mine
was down to 2.5. I am guessing some software I am testing did this. But now
that I have that bumped up, my current is much higher. Like 3.25.

The CAL CUR made a big difference. And after I powered it off and back on,

Although I follow your thinking, I speculate that the MC1350 IF amplifier
and NE602 Product Detector in the K2, and possibly Q25, could be generating
much of the nuisance audio hiss, even when the RF Gain is turned off.
Unfortunately I cannot power up my K2 at the moment to check this

The basic KX1 covers 40 and 20 meters. The KXB3080 adds 30 meters and 80
meters, making it a 80/40/30/20 meter rig.
If you aren't interested in 80 meters but want 30 meters, there is also the
KXB30 which only adds the 30 meter band.
