Andy,
That appears to be a TS-590/HDSDR problem and not a KPA500 problem.
You can likely get more support from th TS-590 and HDSDR forums than
from us on the Elecraft reflector.

First, check all power connections. And if your radio is powered
through a DC distribution strip, my suggestion is to not use the strip
for the radio power. In other words, connect the radio power cable
direct to the power supply. Also shorten the power cable to be more
convenient and
Does this happen without the amp?

The squealing PSU fan issue was so bad, I didn't turn the KPA1500 on for many
months. When I finally did, the squeal was gone. Since it did not turn up on
burn-in, I can only guess that some jostling in shipping did something. After
hours of running it has not come back. Better yet, with

That issue went away for me when I switched to a shorter heavier power
cord. How long/what gauge is your present power cable?
Running 10 watts shouldn't present a problem, not much current draw so
not much loss in the cable/connector.

And don't forget that he modified the Baudot code (he called it upper

Those were fun days.

The P3 SVGA USB connector is intended for a keyboard or memory stick,
which are low-power devices. For that reason, the current is limited to
a single unit load = 100 mA (x 5V = 1/2 watt).

Yes, I believe that is true. Wayne and Eric are long-time supporters of

I've found that all USB cables are not created equal. Some are
apparently better shielded than others. I tried and replaced 3 or 4
different ones / brands / lengths, in the same location and
configuration {between my K3S and my laptop} before I found one that did
not cause the WSJT-X
Pretty cool. Might have to look into this...

Looking for the specified current that can be supplied through the keyboard USB
connector. USB2.0 spec says 500ma. What current (ma) is available from P3?
Is it limited to a lower value through a current monitor / switch?

The new software release V1.27 (6/21/19) will now allow WAN connections to your
KPA 1500 for true remote operations. You can now get rid of the extra devices
and or computer to control you KPA1500 remotely outside your LAN.

In my experience, radio amateurs behave like the general public with
respect to intellectual property; they generally only respect property
rights in physical objects. They'll copy magazine articles without
paying royalties to publisher, play videos at clubs in spite of the home
