Oh yes, I remember now yesterday I got a soft fault on the KPA500. I turned
on the K3, the KAT500 went to the pretuned setting on 40M and then I turned
on the KPA500 and clicked it into operate.
I said one word and the KPA500 went to standby. No red lights. I returned
it to operate and everything
Chuck,
I seem to remember reading that the order of turning on the K-line is
important. I always turn on the KAT500, then the KPA500 followed by the
K3/P3. I have not had any issues doing things in that order. Maybe this
is why you had the 'problem'?

Yep.

(BTW: The KXV3 is very useful, also when you have no intention to add a P3)

Dear K2 users,
there is a revised version of the K2 operating manual in German available.
You may find the text at http://qrpproject-blog.de/?p=64 .
The manual is a compilation of operating instructions and tips from a wide
range of sources (mainly Elecraft's manuals, of course).

I'm hoping the sheet metal issues have been cleared up regarding the K3/0

Any news on ship date?

Greetings Everyone,
I have to say I'm a bit overwhelmed with the number of responses I've received
to my question about what options to get with a new K3/100. I expected a few
replies, but nothing like what I've seen! Thank you to those that have
responded both on-list and off. I very much
The KAT500 needs to be powered on whenever the K3 is on in order to avoid
loading the Auxbus. It can be powered up at the same time, but must be on
before the K3 completes its initialization.
The KPA500 has no restriction, and can be powered on any time before or after
the K3 is turned on.
I know I am late to this game but I recently got my K3 back and I missed or
need these features the most.
1) KXV3 - for my receive antennas.
2) Fully filled up filters in your receiver - still want to get either 700 kHz
or 1k filter for it. I have 13k, 2.8k,1.8k, and .25k.
3) and I like the

Unfortunately there is no mod solution like this for the KPA500. The
feedback circuit could be changed but I wouldn't mess with it unless you
know exactly what you are doing.
Actually there are mods from EU and according to their users they work very
well. One forgoes

Is there a more favorable order to get them? Amp first or tuner first? I

Hi Dennis
The is a another consideration for digital modes if you are planning to
work RTTY as well as other digital modes. In setting up my K2 a long
time ago, I found much better results with narrow filtering could be
achieved by using an audio frequency pair (mark and space tones) lower
John,
There are no real issues with installing either the KPA3 or the KAT3. There is
a shield that is included with the KPA3 kit (I don’t believe it comes with the
base radio, but it has been 4 years since I built my kit) that might be easier
to put in before the KAT3. Personally, I’d get them
Thanks, Chuck.
Apologies to the group for omitting a subject.
I was thinking amp first simply because I do have a tuner, although manual, but
I do not have 100 watts. Doesn't sound like either way would be significantly
harder than the other.
Thanks 73,

Well, if you need the KAT3 to operate 100W with your antenna(s), then
I'd think you want it first. If your antenna(s) present a suitable
load, you really don't need the KAT at all, so I'd go with the KPA. You
might want the tuner for operation away from your station, add it second.
The KPA
Arlen, I have a P3. I bought it as a toy, my wife does needlepoint

to use it, and far
So then it's all up to you, John: Do you want to
eliminate manual tuning or have 100 W output more?

You might want to say how you have the KAT powered. In my station I have a
