Buck,
Which transceiver and which microphone?
If the K3, are you using the front panel mic jack or the jack in the
back?
How do you have MIC SEL set?

Dan,
In my opinion, that fuse block will be difficult for an amateur without
at least some limited sight.
First you have to use a screwdriver to pry out the block. Inserting the
fuses might possibly be done using only tactile sensation, but inserting
the fuse block the right way up so the

Gary,
Have you considered that there may be something in your antenna system
that is heating up or otherwise changing with the 1500 watts power?
The first thing I would suspect is a balun that is heating, or a
connector that is not quite tight enough.
Those kind of problems will not show up
Ray,
Any important mods would have been installed when it was returned to the
distributor.
Yes, there may be some other mods, but they should be of minor consequence.

Don't forget about the POWER slider in WSJT-X. It is not a power
control at all, it is just another audio level control.

Tony,
Check your audio level settings - there are at least 3, the KX3 mic
gain, the soundcard level in your OS and any "Power" slider in your
software application, and if you are using a SignaLink, there is a 4th,
the knob on the SignaLink box. They should all be near a mid-range
setting.
That is the antenna I use on 80 meters. It has a double-humped SWR
response and stays below 2:1 between 3500 and 3900kHz. Up at 4000kHz it
is a little higher than 3:1. The 1/4 wave 75 ohm section is a
transmission line transformer. The 1/2 wave 50 ohm line repeats the
impedance at the
I agree that Tom Hammond N0SS (SK) created a valuable website with a lot
of information related to Elecraft products (particularly the K1 and K2)
and ham radio in general.
I am thankful that the Mid-Misouri Amateur Radio Club chose to preserve
the contents of his website within their website
Henning,
There is no need to *program* the K-Pod itself.
You do write Macros for the K3 (use K3 Utility to enter them) see the K3
Programmer's Reference for Macro command structure.
Then the K-Pod buttons can initiate up to 16 K3 Macros - a tap initiates
macros 9 through 16 while a hold
Richard,
You may have better luck with Noise Reduction than the Noise Blanker.
The noise blanker works best on impulse type noise.
