Well said, Bill. I used to sign /QRP but stopped doing that routinely and
increased my CQ return rate. Nowadays I do not mention my attic doublet unless
the subject comes up. Why shoot myself in the foot...
I have nothing against small loops. I built a simple 40 meter STL from about 8
feet
I used to have a mag loop too. It is ideal when it can be transported in
nearly original condition, when no tuner is available, and when tall
structures are unavailable. With a loop, one can be in the air in seconds.
However, the loop weighs a couple of pounds and it needs to be adjusted very
often
batteryspace.com has a 20A LiFEPO3 battery for $120 and weighs 7lb, half of
what lead acid does. Good for a couple of hrs at 100W level. This battery
charges real fast.

Folks - We are exceeding the single list posting topic limit for the subjects on

OK, OK My only intent was to suggest that attic antennas are
sometimes surprisingly good and not to forget your VHF/UHF bands as
in typical wood-frame houses work pretty good.
Yes there is absorption by the roof and walls but so it there in a
forest or in the downtown urban concrete "jungle".

Hello,
I have built a 21' loop for 30 and 40m, which I use inside the house on
the second floor. No problem reaching Russia on 40m with 5W, CW...

When I built my present (brick and frame) home in 1996 I was fortunate enough
to work with my builder and architect and had them design the attic to be void
of all HVAC ductwork, AC wiring, low voltage wiring (alarm and telephone) and
stereo speaker leads. The builder thought I was a kook (not
A poor antenna has infinite gain over no antenna.

Hi all,
A recent thread on the KX3 list helped me identify a bug that was causing the
ATU to retune from scratch unnecessarily at times. It now correctly tries
existing band-segment data first. It also now updates LC data (if required)
when you use A/B swap, REV, SPLIT, and FREQ ENT. This saves
Brandon gave me about an hour on the phone, and we got all the settings just
right. I can now operate remotely using RemoteRig and the K3/0 to my K3/100.
It works --- with a couple of quirks.

I ran my club's FD GOTA station off battery/solar power this year. The
GOTA station was in heavy use for about half the 24 hour period, and
lighter use for the rest.
Over that contest and several others, I've developed the following
guidelines for my K3:

I am not an authority on Remote Rig, but it would seem to be that JMP1
controls the microphone bias.
The Heil Proset-K2/K3 sold by Elecraft is essentially the same as the
Proset-iC in that it needs bias to operate.
There are so many versions of Heil microphones that one needs to be

whomever had suggested it to me here on the list. Turning IQ on will draw
around 10ma more power by my reading, but it's worth it not to hear that
godawful squeal, IMHO.
