[Elecraft] K3 and N4PY Software

[John Huffman]

Computer control can really add to the enjoyment to using a K3.   I 
thought I'd pass along my experience.

I've been using computer control with my radios for years.  The newest 
version of the N4PY rig control program is a good match to the 
capabilities of the K3.

Using N4PY I can perform most of the radio functions from the keyboard 
and the mouse.  Easy QSY is a good example.  There are separate buttons 
for two or three modes per band.  The Band/Mode buttons return you to 
your last frequency for that mode on that band.  It's much better than a 
memory that will only go to a preset frequency.

The program allows you to use the mouse wheel for up to ten different 
functions.  I usually use it to change frequency.  But, if I hit a key 
on the keypad the wheel can be a volume control.  Hit another keypad 
number and the wheel is RF gain or RIT or pass band tuning or filter 
width.  There are lots of possibilities.

The program controls the K3's functions and extends that control to 
external equipment.  It interfaces directly with PowerSDR-IQ when using 
a LP-Pan panadapter to allow clicking on the panadapter screen for 
changing frequency.  It interfaces with the K1EL Winkeyer, LP100A 
wattmeter, LDG tuners and coax switches, and some Tokyo High Power or 
Acom amps.

The program has all the bells and whistles but has a clean and simple 
user interface.  The learning curve is relatively short.  If a K3 button 
is not part of the standard N4PY program interface, there are six 
user-defined buttons to control any tap or hold button on the radio.

If you are interested in a different way to operate your K3, the N4PY 
program is worth a try.  It's not a free program, but a time-limited 
trial version is available.

I have no financial interest in this software, or any other for that 
matter.  Just a very satisfied customer.
