Why are you trying to make this so complicated? It's a straightforward
calculation. A half-wave dipole is assumed to have 0 dBd gain (what a
surprise) or a multiplier of 1. (There is no mention of ground, takeoff angle,
blah, blah, it's zero dBd, period.)
You model the antenna you want to us
Hi Manuel,
Have you tried swapping synthesizers? Perhaps the one used for the sub
receiver may be bad.

Absolutely! So let's read the reg and see what it says. Most arguments about
the rules can be resolved quickly by doing this. When reading regulations,
contracts, or other legalese, it's important not to read between the lines
or "interpret." Read exactly what the words say
ARRL ain't the FCC. And the ARRL's opinion is no mitigation whatsoever if I
get an FCC pink slip. The reg is the reg, and it's a strange brew for the FCC,
where ERP normally has nothing to do with dBd.

One of the open questions regarding the continued development of the K3 that
has come up, has been the maximum width of the DSP. The K3 appears to be
effectively limited to about 4.3 khz, as opposed to +6khz in some of the other
radios that many of us have access to. Some have express concern t

I also gave my K3 a pretty good workout in the 7QP. 1370 QSOs and
about 220,000 for a claimed score.

Hello All,
Now I am having the power creep up problem,
It seems like there is always something.
Is there a fix ???
I'm using the latest firmware.

Sounds like a typo in the manual. There is no "MIC SRC" (that I know
of).

However the menu listing on page 52 doesn't list this entry. It does

you have to change MIC SEL each time

Do you have the Rework Eliminators installed in that K2? If so, follow
the instructions in the RE manual about the additions for the K60XV
option. C71 is changed to 120 pF with the RE change or the installation
of the K60XV and requires that you set the secondary menu to D19 = Y.

I set the VCO voltage at 4.0Mhz to 6.0v with L30. On 40M, the voltage
is 8.31v and does not change as the VCO frequency is varied. All other
bands are within range and behave normally. I don't know which
relay(s) (K13-K15) or capacitor(s) (C70-C75) may be at fault. Any help
appreciated.

I don't find the K3 complex. As a matter of fact, I rather enjoy
playing with the new features.
One doesn't have to upgrade the firmware if he is happy with the radio as is.

Wayne,
Your email response to John's honest concerns is one of the many reasons I
love owning a Elecraft K3. There are multi layers of intellect within our
community and you try honestly to address all of us. I personally am in the
lower tier and wish I had more experience to get full benefits
To me the K3 is pretty simple. I turn it on and use it. If I want to
change things I can but I pretty much don't. I just turn it on and
operate. It's like a modern HW-101 for me, just as simple as can be.
Now, as to "promised features vs. fixes", this is a tough call. If the
features had not
