This will give you an idea how used the box was at the start of the project.

Almost there, this is the hole for power plug that broke.

And yet another idea how used the box was.

Did not bother to make a parts list BUT did get a picture of the parts.

The inside  was not any better than the outside.

Finished product.

About a week before Christmas 2016 I bought a SDRPLAY RSP2, yea Merry Christmas to me.
It is pretty nice but I was not sure I wanted to modify the TS590S to tie it in as pan adapter but knew I could not transmit with the SDR on.  So I would stop the SDR every time I wanted to transmit and start it after that and you guessed it, what a pain.  In talking with some others I decided to build a relay box to disconnect the antenna and ground the SDR when I keyed the 590.  I found I could use the amplifier keying relay accessible with 7 pin din on the back of 590 to key the relay.   I started digging and found in my reliable junk box picture #1 and a re-used (many times) project box to put all the parts in.  As you can see in #2,#3,#4 the box was pretty messy.  So when all the holes were drilled & cut & checked, I sanded and painted it, #5.  I had a power receptacle picked out for the end to re-use the existing hole.  Well Murphy knocked at my door and the connection broke.  Dennis KCØYKN just happened to stop by that day and said, well look what I ran across on Amazon.  It is the two little plates in #6 and with those ($5) and 2 regular power pole connectors you now have a chassis mounted power plug.  Great I said but where the screws had to go were in the open space of the old one so had to cut a piece out of yet another re-used project box that had been re-used beyond its time and made a cover and it works great.  I added a small fuse inline just in case and now I can put the test leads away for another day.
