Perhaps a switch that responds to commands spoken in Morse code.

Supposedly capable of switching 15A and it sounds like they can handle
moderately inductive loads. Problem solved. Although I did have to
think about what to use the other two in the three-pack for. There was
nothing in the shack that I "need" to turn on and off wirelessly but I
found something to use the second one for. They have been working well
for several months. We'll see if they survive our thunderstorm season.
Ironically, I did put the third one in the shack last week so I could
remotely reboot my LAN connected SDR receiver when it drops off the
network. I suppose you could use one to turn the PS7 and a FA7 on the
rig on at the same time, saving having to rig up a DC fan. It would
take just a short extension cord from the FA7 to the 2nd receptacle on
the box.

I never liked the fact that there was the AC for the PS7 routed
through the TR7. I have used a good power strip for years and tried to
not switch the volume control to OFF since I read about them being
unobtainable, and failing both electrically and mechanically.
Working on a project TR7 and PS7 with a younger ham, I decided that I
should finally figure out how to keep the AC out of his and my TR7s.
As we were checking out the PS7 I looked at the circuit board that has
the voltage switching and all that (mounted by the switches being
pop-riveted in place, seriously???) and decided there had to be a
better way that to mess with that wiring.
And then an idea came to me that should have 40+ yrs ago when I got
the rig. Surplus Sales has the Jones connectors (for a cable, but we
did not connect any cable) that are the same configuration as on the
back of the rig. Part Number: (CNE) P310CCT
With it we just jumpered pins 1-2 and 3-4 inside the connector (check
your PS7 and TR7 manuals to see) and then plugged it on to the cable
from the PS7 and it works just like the PS7 was plugged into a
turned-on radio. If you need ALC or VOX, you'll need to get another
connector to plug-in to the back of the TR7, but we have not needed
either yet.
Then we leave the PS7 cable that has the AC and wires for the ALC and
VOX coiled up behind the PS7 and turn things on with the power strip.
Now only the 12V cable is plugged into the TR7. Of course the fan will
need to be changed to 12 VDC on the radio. That will be our next
upgrade.
Before recommending the Jones connector from Surplus Sales to the
group, I called them to make sure there were more available. They
checked stock and said that they should have at least several hundred.
Thought I'd share this idea with the group. I am sure others may have
done something similar, but it is nice to know where we can still get
Jones connectors at a reasonable price.
