Have anybody got the KX3 Companion App for Android to work?

Also, the App has a 4 seconds delay after the last text is sent, and there
doesn't seem to be possible to adjust this delay.

Martin,
I cannot make any comments about the app locking up after TX, but I can
comment on the 4 second delay - I assume you are using data modes.
When sending data modes that originate as ASCII text, the KX3 (and K3)
have a 4 second hang time to allow for interruptions in typing.

stretch, is fairly slippery and only a
This is an interesting discussion about antennas for forest regions where you
have very tall trees. I have a lot of trees, but getting an antenna to 45 or
50 feet would involve very small branches. I have mostly Chinese Tallow Trees
with some Ash and Beech, so stringing a wire from trees is
I'd very much like to see a response from Elecraft on this one; perhaps they
are running some tests of their own? If proven, maybe some sort of hardware
solution is needed.
It would be a pity for the technical problem to be lost beneath a debate on
slang terms.

Do not think the lock up is due to the app, but rather to interference on the
connection between the KX3 and the tablet/ phone. An opto isolator should
eliminate this. I had a similar problem with both HC and other Amateur
software.

One of my Elmers showed me another way.
Purposley choose the twig ends of the branch of a huge tree. Use this as
your center of the dipole, or whatever. Blow a line all the way over the
tree, and attach it to something other than the tree. Pull up the antenna,
and leave rope line going down
The lock up happens even with 0 watt out to a dummy load, so I don't think that
interference is an issue here.

Yes, I think KX3 Companion does work. Shortly after it was first released,
I downloaded it onto my Motorola Droid Maxx. Once I obtained the OTG

work very well. I haven't really had a chance to use

Hi all,
I've added an experimental fast-play mode to the KX3 to allow play/repeat of
message buffers 1, 2, and 3 with a single switch press (1 and 2 in the case of
voice modes, which use the built-in digital voice recorder). In this mode, you
don't have to tap MSG first. The K2 has a similar

For pre-built antennas, HyPower is a good choice. He has lots of options, fan
dipoles, loaded dipoles, even combinations. I have a fan dipole made from a
full-size 40m element and an element that is full-size for 80 and loaded for
80. He also sells the loading coils if you would rather DIY.
That's a good and useful presentation. Although they don't affect Jim's

Johnny I too am using one of John's KB8UHN heatsinks.
My first impression is the quality and price. I opted for the unpainted version
and I like the way it matches the KX3 lettering and contrasts the black.
I have not used it in heavy digital transmitting but this weekend.
It fits well with my

The K3 uses up-conversion 6 m, which inverts the sidebands. It should stay in

My only method of raising wire into the air to act as dipoles (actually fan

Jim's presentation is excellent, covering lots of trade-offs that most

I have a theory about this.
Compare a vertical to a dipole. One reason for additional noise is that
a vertical is omnidirectional, and noise comes from all directions. The
signal is coming from one direction, and if it is the right direction,
then the 2.2 dB gain from directivity of a dipole

Hmmm. Interesting theory Vic. I agree that ambient noise probably
doesn't have any particular polarization. My dipoles clearly have less

Thanks in advance.
Short wave listeners use kites and baloons to hold up long wire antennas
all the time. I did this long before becoming a ham.

I remember that Benjamin Franklin was a short wave listener -- his radio used a
rusty key as the detector. His resonant circuit included a Leyden Jar
capacitor. He quit this hobby though when, during an electrical storm, his
lightning protection failed and destroyed his rig. Embarrassed
The SPE Expert Amp needs a separate connector to the port. It does not do CAT
control, but rather connects to a separate program to duplicate the control
functions on the front of the amp. For CAT control it connects to the DB-15
Acc connector.
