It was good to get back on the net. As many of you know, my K2 has been
inoperable for about a year. I had worked with Gary and determined the
final transistors were shot. That is where things went terribly wrong.
Let me say now, building the Elecraft K2 was my first major build. I had

Joe,
The first thing I can say is that you should check your soldering - it
sounds like the entire receive chain has lower than normal gain, and things
before the Mixer are likely OK since you can peak the tuned circuits. Check
the DDS and BFO injection levels to the Product Detector and the Mixe
Wow is all I can say.
What a great way to spend a Sunday evening. The NCS hat got bounced
around and there were check ins from all over. Then there was Carter,
N3AO. Eastern Pennsylvania better watch out! There are buttons popping
off this guy's vest. Congratulations to Kay and Carter,
I wonder if someone, who has experienced and had the
operating success with this BEAD-WIRE ANTENNA -
could consider documenting it, with an Adobe
article, photos perhaps, and diagrams, and what
the heck - dimensions?
It sounds like a good antenna - for us antenna

HI! I am building my KX1, and have gotten to the receiver alignment stage.
I am using an XG1 for my signal source on 40M and the 50uv S9 signal is
audible and I can get a good peak on the 40m trimmer, but it isn't as strong
as an S9 should be. When the XG1 is in the 1uv position, I don't hear it
I do likewise. If the QRM is close in frequency and strong enough to
pump the AGC. I typically disable AGC by turning the AF gain to max
and using RF gain as a volume control (just like I did in the old
days of simple detectors and fixed AGC).

I have units listed below and the # 35 SN with most all upgrades does not
have the problem. Buying a new one and building it will not resolve the
issue with the old. The techs on this list can help you or you can send it
in for a complete checkup and fix if you are ready to through in the towel.
FWIW: I use fast AGC on CW, and either med or slow on the rare times
I'm on SSB. In a QRM-free situation with either slow or no QSB, med or
slow AGC is probably a bit easier on the ears. However, in rapid QSB,
the AGC doesn't recover fast enough and the signal falls below the
threshold of my
UG-1185's are ... in my opinion ... very easy to assemble.

The K2 is the first rig I've had that has adjustable AGC. Under what
conditions would one benefit from using fast AGC? It seems that slow
AGC is easier on the ears on CW.
When receiving very weak, fading cw signal you could benefit by
switching AGC fast.

I do use "fast AGC" at times but I'm basically a "non-AGC" CW operator
unless I'm just casually tuning around and chewing the rag with stations
with good strength. I don't appreciate listening to band noise that is
greatly amplified above its real level. If a signal is 20 dB above the
background no

FAST (or OFF) AGC is the only setting is EVER use on CW!
If you only work the 'strong ones', then using SLOW A
Hi All,
I've recently completed my KPA100, and have noted that I have low pwr output
on 30m (into a dummy load)
I am getting about 75w out on this band with Hi-Cur message
I've checked the low pass filters on this band using an Antenna analyzer
connected to the SO-239 jack of the KPA100

True, it is also much easier to weatherproof N connectors than 'UHF'

Hi Jeff,
Putting aside not using AGC at all, whether you use fast or slow AGC for
either CW or SSB depends on how quickly you want the receiver to recover its
full sensitivity after being smacked by a strong signal. The 'fast' and
'slow' refer to recovery time. In a DX pile-up situation when u
