First thing and foremost - switches are mostly not relevant to protection.
Energy that can travel 1000' through the sky is likely to continue across
most switches. So, the utmost of safety is what you indicated you did -

Do not use the KX3 tuner when using a mag loop. Set the tuner to bypass.
A mag loop is the tuner. In order to gain resonance, adjust the mag loop's
capacitor to hear maximum noise at the frequency you want to start working.
Mag loops are high Q, resonant in a very narrow range of frequencies.
Correction - could be 3R3 - that's an inductor.

If your antenna is a magloop - DO NOT USE the tune button. In fact, clear

These is nothing unique about the Elecraft serial cable except possibly the

I made a confirmed contact 1:52Z April 15 with LZ2A0 in northeastern
Bulgaria 4607 miles from my QTH using my KX3, a Bioenno battery, and an
Alexloop antenna. All this inside my house in Lowell MA USA, not even by a
window. The contact was so good we had a brief conversation about my rig

The really short answer is "all of them" and even more so if you are buying

find something to do with every option. I got mine fully loaded except for
the 2M transverter. The reason I didn't was that I already had an HT at

What is even better is the obvious lack of issues with Elecraft products
I almost hesitate to weigh in since so many others have. The HP41 app is
actually an emulator which runs the actual firmware from the original
calculator. If you have HP41 programs you like and don't feel like porting
them, this is the best going. However, I like "Free42" which is a complete

Nothing wrong with the switcher or with the Pro Audio.
What I am happy with is the BioEnno is the BioEnno 123AH battery. It's small
enough to fit into the "shack in the pack" or something similar in size.
LiFePo batteries such as this one can

With regard to the charging the Eneloop's, they come fully charged and thus
setting up to charge them might deliver an error.
One other possibility, what is the minimum operating voltage (Bat min) in

Hi Walter,
In response to your comments on my post, the terminology you use and that I
used both appear in various texts to describe the same thing. Not
surprising, we both know what one another mean. I prefer incident because
quadrature is in relationship to that. An AM signal would appear on
My career has been in software/hardware systems including some with signal
processing. Digital filters ultimately embody mathematical equations which
operate on a matrix of samples represented as complex numbers. IQ stands
for incident and quadrature, sine and cosine, real and imaginary or x and
My rule of thumb is that if you can keep your finger on it for a second or
so without pain, it's not too hot.
The ambient temperature is really not the issue as much as whether heat is
carried off. I know it's hot in the pacific northwest but I think you can
still enjoy your gear. The

No - the KXBC2 is not suitable for the Bioenno BLF-1203W, you should use the
charger sold by Bioenno for this purpose. Bioenno products are LiFePo, a
different kind of LiOn Chemistry than the Elecraft ones. The Bioenno
charger will work for all the higher AH batteries they sell that have the DC

The reason to keep smoke detectors from Amateur Radios is that they detect
smoke by ionization from a radioactive source. A strong near field will set
them off. The good news is that this is your indication that all is not
