Good Evening,
QSB was very slow and not very deep; a little faster on forty
meters. Both bands were quiet, so quiet it wasn't easy to find anyone.
The smoke and fires are creating lots of problems in California.
Hopefully the recent cold front will reach them and slow the winds.

Most hams cut their antenna length for lowest VSWR which is often NOT the
resonant point. Resonance occurs when XsubL equals XsubC. That means there
is no reactance at one frequency. Impedance varies greatly with height
above ground. The greatest radiation occurs at resonance which, again, is

I had a KPA500 at my remote station and I know that I have managed to leave
it on in Operate for weeks at a time by accident.
I don't think you need to worry about it.
Besides, it is a great watt meter even if you are in standby!

I agree with your assessment. When developing new firmware, I use a standard
cable for testing. But in my station, I use custom-build cables that use only
10 or 11 wires plus shield.
I believe the the very first cable we tested with used only 10 lines between

Jack,
Don't use a 15 pin straight through - not all pins are to be connected. My
recollection is that 1 or 2 pins Must Not be connected to the K3!
Use the manual if not using the Elecraft Aux cable sets.
Because not all VGA cables are the same - you can use a VGA cable if you
positively confirm

Yes indeed. In the PA module PA voltage and current are measured before K4
which is controlled by "60V ENABLE".

My kpa shows HV 76 both in standby AND operate. Drops to 61V, key down, 500W
output. AC line input drops from 124 to 122V at same time.

Hi David! Great to hear form you...
To expand a little on Don’s excellent info, The PC connection for both the

you can send data to them from a transceiver (usually Kenwood) to control
things, for your situation, th
The specific answer to your question isn’t in the hardware, but rather the
firmware. With that in mind,
going to STBY does the following:
1) Bypasses the TR switch, so that the signal path goes direct between the
input and output RF ports.
2) Turns off the 60V power to lessen the load.
3) It also

I have a Kill A Watt meter. Plugging the kpa 500 in with front switch off draws
7 watts. Standby draws 12 watts and operate draws 13 watts. 500 watts out on

Hope that helps.

Antennas are my passion. In 50 years of hamming, I have probably experimented
with virtually all variations of wire antennas. My current antenna is far and
away the best I have ever built.
Without going into all the details of my design considerations (location,
regulations, budget, etc.) let
If you have a pet larger than a goldfish, you should probably put it
