Finished K3 build.
Using 100 W amp option
CW mode, set power to 50 W
Hitting the Tune button seems to draw right amount of current, but when I
exit Tune and start transmitting, only a fraction of that current is drawn
(no wattmeter here so I have to watch the current meter on the power
supply).

Andrew,
The XG2 is controlled for its output *level*, but the frequency is
dependent on the specific crystal.
Much better to use WWV as the reference for calibration than the XG2
(unless you have previously measured the XG2 frequency with a precise
instrument).

Perfect! The higher the frequency you use the better!

I ended up using WWV at 20.0 MHz.
Works great.
Problem was that the freq must really be known -- i.e. the XG2 won't cut it,
unless I know its exact frequency...
Thanks all

No you're just able to have the dummy load on either port when you do
so.

Arnie,
Try the recommended lengths first. While they are not optimum for any
one band, they certainly are known to work. Just throw the *insulated*
wire over whatever support is available and connect it to the BNC center
conductor - the 16 foot "counterpoise" wire connects to the BNC shell.
IMHO, For those starting out who do not realize there is such a thing as
performance differences and want everything in the cheapest package they can
buy, there are the small box 100w mobiles availabe for 699 I think. That
creates a lot of sales to first timers. They are looking at 699 vs 2149
I like the "near end fed" which uses a small 1:4 turns ratio (1:16 Z ratio)
toroid at 10% from the end of a half wave dipole (for whatever band). Put
the transformer (and tuning cap if needed) into a film canister. This makes
the coax length shorter/lighter for a lot of situations. Being sho

This topic greatly interests me, because I have never found saturation or
non-linearity in typical cores an issue.
This might be an opportunity to explore something new that I have never
seen.

They are the same, although for a washer or lockwasher, the 4-40 is a

Hi David,
If of any interest to you I can send you "off List" some results of my most

I didn't know that about small cores, but, if I were to take on this idea, I
would use the biggest I could get in there, which is around 45mm.
There's a local radio station on medium wave which has given me grief in the

A Low Pass filter cutting off above 6m is useful here, because our not so
