My solution to this has been to get the HF (and VHF) antennas as far
away from the house as I can.
Back in the late 80's I was chasing satellites for the first time. One
day I ended up with the antennas pointing downward and as I was rotating
the antenna, the array looked through the house.
Since my computer is now the radio I also ground the chassis of the computer
to my single point grounding system.
I've also learned some cheap computer power supplies do the minimum
filtering.

I have just added a section to the FlexRadioWiki where people can enter the
information about computer systems that are known to run PowerSDR. The idea
is to give people who are thinking about getting a machine to run PowerSDR a
place to look for suitable systems.

Can you say 'MIDI'? It was designed exactly to capture fairly complex
gestural information from multiple sources, in quasi-parallel.
There are skillions of control surfaces that will emit programmable
sequences of MIDI messages.

What is the value of a successful tune in the ATU form? The default is 2.1:1
so 2.0:1 would be a successful tune.
What the ATU will match is based on the complex impedance presented to it and
not a particular SWR value. If you are suddenly having problems, then I would

Tim,
I did some more looking and tried the tune on other bands.All the
bands, from 6 to 160 tune the first time, and to low SWR, except
suddenly 80 m fails most of the time.

Based on the user manual (occasionally RTFMing can be productive)
It is going to take a minimum of 5 watts for it to work. That is at the max
end of the 1500's RF output so you may not have enough RF output to tune the
ATU. I have this problem with a CG-5000 ATU

This reminds me of a strange problem I had at one time where the Flex tuner

Turned out the antenna system was highly reactive at certain frequencies.
