For a K3 used during Field Day, the power, compression, and mic gain can
be locked by pressing 1 from the PWR SET menu. I was wondering if there
is a way to lock the antenna selection on radios which have the KAT2
installed? If not maybe this could be added to a future firmware update
by
Mike,
I always put a dummy load on the unused antenna connector for that very
reason. Adds a margin of safety for FD and demo events.

The K3 is a proven performer at Field Day, whether running QRP or QRO. While
the K3 doesn't have the ultra-low current drain of the K2 or KX3, its current
requirements are still quite low compared to other high-performance desktop
rigs. At QRP levels, it can typically operate for the entire
To add to this: In the case where you have a horizontally-polarized antenna and
a vertical, it might feel like the vertical should be placed off the end of the
dipole, but in fact that's where vertically-polarized response of the dipole is
maximum, so the vertical should actually be placed
Just my $0.02.
On one of the two K3's we had at FD (NR3X), we used an 80M dipole fed
with 450 ohm ladder line.
Operators could not believe that I terminated the ladder line into a
4:1 balun, then directly into the K3 (KAT3). Using the internal tuner,
the antenna became a multi-bander without

All,
See you on the bands from northwest Missouri camped at Lewis and Clark State
Park running solar power with a full gallon QRP. Have a safe and wonderful
2009 Field Day.

If you worked K3MAD on 40 meters, than it was a K3 on the other end.
Wow this rig is great! Its biggest problem is that there were some
weak stations out there that we could copy no problem, but they
couldn't hear us, sort of reverse alligator syndrome!
The CW decoder worked OK, fortunately, I
Don't underestimate the voltage drop in your battery cables.
My old ICOM 735 shipped with a ten-foot #12 battery cable, which I used on
Field Day without thinking. Later I realized that I was losing more than
half a volt in the cable. That's a lot when you're running from batteries
with a rig
The K3 can be used at QRO power levels (13-120 W) when powered from a
car battery or a large gel cell. Here are a few things to keep in mind:
- A battery that's significantly discharged will have higher internal
resistance, which will cause the voltage to drop when high current is
drawn.
