I just built a KX-1 and it works FB, I installed the 30-meter module
today and when I went to test it, there are no peaks on 40, 30, or 20m,
and the rig recieves no signals at all. Pin 15 on the CPU which goes to
+5V to turn the 30m module on, stays at 0V. I finally removed the 30m

Hello' Elecraft community...
I have just received my XG1 Kit...
I'm wondering if I have any chance to use a different XTAL to make it work
somewhere on 14.XXX MHz...
What should I do for this?
Any hint *VERY* appreciated!
Happy Easter everybody!!!

Yay! My K1 (4 band) #1870 is alive and well...
I built it last summer, after buying it at Dayton. Everything worked
great, and then 20 meters suddenly failed. Stone deaf and no output.
All other bands were fine including 15 meters, which shares circuitry
with 20 meters.

Check out the KIO2 programmers reference guide (www.elecraft.com) to see
what the output really is. It is easy to try out the commands using

Hi Everybody! I have in mind a killer app for the k2 but it would
require that the K2 send an ACSII output every time a parameter was
changed from the K2 by the operator. Is the case or do my creative
juices go down in flames.

Let me offer the advice you didn't ask for,
Yes, they share the same parameters.
Thank you for explaining that. Is that because the DSP can't find out
the mode? So you can optimize the DSP for CW or SSB? Or am I confused?
You are not confused -- at least not on this point :-)
The denoiser is common to both the CW and SSB audio path

I am not too savvy on this DSP stuff. The denoiser seems a bit
strong for SSB. When I turn it on it seems that it takes a pretty strong

George,
Do 2 things before rewinding T5:
1) check T5 visually and count the turns - the direction of the turns should
look like the illustration in the manual - and you did wind it on the yellow
core did you not?
2) Measure the frequency that is being produced on the low end of each band

I just measured the resistance from the 1-2 side of T5 to the 3-4 side and

You should be able to tell if you have wound T5 correctly without removing

Now unless I misunderstand an EFLWA (end fed long wire antenna ) can
be used as long as it is a 1/4 wave length of the lowest operating
frequency and has a counter poise? 80m would be 66' as would be the

Hi folks,
I'd like to again point Your attention to an old problem with my K2 setup.
My setup includes: K2 s/n 2360 with all official mods and newest firmware,
KPA100/KAT100 in EC2 enclosure with KPA100 F/W V1.10 and the newest shield
upgrade.
After making the last F/W updates the problem seem
Hi
I checked all you said and the voltage still wont move
I ohmed the t5 out and its about 350ohm across from 1-2 to 3-4
all else looks good. 80&40 are the same voltage
20/17 are under 4.5v 15 is the same as 80/40 abt 7.95v
12/10 under 5.5v I think t5 will have to be rewound?
What do you think?

Jim,
Those components will not be needed on your K2 (or any other K2 above
SN3000) - it already has the components installed for KPA100 support.
Elecraft does provide those parts in support of those folks having an older
K2 and adding the KPA100.

Once you have the unit set to your liking -- and the defaults may be

It sounds like rather than regulating, you would only need to drop the
maximum available voltage to about 14 volts. 3 or 4 series diodes should do
the job nicely - and you could easily use a switch to short the diodes after
the battery voltage falls below 14 volts. If you limit the maximu

Tony,
The Info 201 message tells me that the K2 'thought' that everything had to

was/is misbehaving.
I would first drag out the schematic and look at everywhere the AUXBUS
