Neil,
When you see an antenna element folded back on itself like that, think
linear loading (look it up in the ARRL Handbook or similar). There is
no magic, but it is one way of shortening an antenna. It is not as
efficient as a full length antenna, but is more efficient than using
loading
Don,
Yes, you should be concerned for the health of your K1. If you have the
KAT1 installed, the wattmeter diodes can be zapped by a charge like
that. Use a resistor between the antenna and the counterpoise and if
you can find a way to ground the K1 case, that would be good too. It

Everyone,
I have had my KPA500 linear for some time now and have been really happy
with it. I use it with my K3 and they communicate with each other via the
DB15 AUX cable that I built ( the one furnished by Elecraft was too short).
The only issue I have encountered is the finals in the linear
A note on folded back antennae. I have a 3 element SteppIR with the 30/40 kit.
The antenna is mounted at about 67 feet above the ground. I have compared the
folded antenna at 67 feet to a full sized inverted V at 40 feet and find
it noticeably stronger. Even though it is only a dipole which

Great. Some of my antennas are in the woods. Dark colored wire and
relatively small wire can be pretty stealthy. The black rope sold by Ham

Indeed! The purpose of the inverted V was for local NVIS coverage and was
mentioned anecdotally to illustrate that folded back elements can be very
effective if needed. They reduce the mechanical problems of erecting and
turning a rotating dipole with minimal degradation. I can see a

My question is whether you actually increased the no-fan heat dissipation
of the heat sink complex that significantly, or whether what you did is
faking out the heat sensor and causing the fan to NOT come on when it
actually should.
It bothers me also that the increased dissipation is

Before I contact service, I thought I might post my problem here in case
it is something fairly simple.

I wasn't able to reproduce the intermittent small voltage drop in encoder
pins 3 and 4 today, when they are disconnected from the board. Not sure why.
I reconnected them and they both show nearly identical resting voltages
(4.4-4.6V) and both vary in unison by a very small voltage (~0.05V)

I would not use a supply that was not designed/marketed specifically for radio
