Dennis,
Are you certain your KAF2 is tuned to your sidetone pitch? If it is not it
will severely attenuate your signal.
There is no need for the AC voltages at the headers pin 1 to match the
voltages at pin 2. The filter and the input to the audio amplifier are
differential inputs and the
Terry,
WARNING - Do not do a hard reset without first writing down all your menu
and filter settings - they will be set back to factory defaults with a hard
reset.
I have trouble believing that a hard reset will correct any problem of that
nature - it seems analog in nature and the reset will
Terry -
I had this problem. The cause was in the KPA100 T-R switch. Don W3FPR came up
with the solution. He increased C31 to 0.2 uf.
Don may chime in with better words of wisdom, but it's a place to start.

I have just installed a recently constructed KPA100 (including the latest
upgrades)
and appear to have run into the erratic power control problem.
Using Tune + Display and an external LP100 meter, if I request 5w I get 5w out.
Increasing power to 11w so as to engage the pa I also get 11w out -
It is encouraging to see Elecraft prosper and
expand, in manufacturing and engineering. Expansion
usually means new products, new features, new
kits.
I put on my read between the lines glasses, when
I read Eric's message about Elecraft's future goals.

Trevor,
That behavior may be indicitive of a BIG oscillation in the KPA100, and the
KPA100 throttles the power back to protect itself. In other words, it may
not be a power control problem after all - check carefully to determine the
real cause. OTOH, it COULD be a power control problem, but

I think you are seeing the attack spike of the ALC, Trevor. The LP-100
responds to very short peaks, apparently faster than the ALC in the rig
can respond. If you go to www.telepostinc.com/K2_ALC.html you can see
examples of this. There is a picture I took of CW keying and one Jack,

Ahmen Sam!
From reading the reflector I get a sense there are
some who want/expect Elecraft to become something
they aren't. I use they in the true meaning of the word.
Elecraft is people. If they get big they will become

Few of us know someone at TenTec or MFJ (Yuk!)

As one of the founders of Elecraft, I consider us very lucky to have
such a dedicated customer support staff. We get raves about Gary,
Scott, and Don, all of whom go to exceptional lengths to help with
assembly, alignment, or other issues.
Then there's Tom Hammond, who has been a super
6. Don't expect very good performance on 80M. The antenna is short
and you are unlikely to be able to put in a good enough ground system
to make it very efficient. Still, it is better than no antenna.

Fellow Elecrafters:
The discussion of verticals has inspired me to do a bit of EZNEC
modeling. I plotted the azimuthal pattern at an 8 degree takeoff
angle for several different 80 meter configurations. In all 3 cases,
I've assumed average ground.
The first case is the classical full size

Everything, to this point, is working perfectly! What a cool radio. I'm
rarely impressed with any new gear I purchase. But I must say that this

Remember there are two sources of ground losses in verticals, near field and
far field losses.
Near field currents are those produced at the base of the antenna. Even

Mike,
What is the possibility that you forgot to install RFC8 (with the 80 meter 2
band board) or forgot to install the jumper if you did not order an 80 meter
board? That would do it.
If that is not the problem, do you have voltage on the IN pin of U5 - should
be almost your power supply

I didn't mean to mislead you: I don't own a 5BTV myself, but there seems to
be a lot of them around. If it is common practice to put them on a pole,
then the pole ought to be useful on the lower bands using the 5BTV and its
radials as at least partial loading for 80 and 160.
