I recieved the vacuum relays from HA1AG the other day and decided that it was time to start building the 20M stack box with out of phase function on two of the three ports. I didn't find any good boxes for decent prices so I took an old box I found at work that had been used for an old research project, I just had to make a bottom, mid section and lid for it. It will not be water proofed but I will still have it inside a big cabinet up in the tower that supports other boxes as well.
Here are some pictures of the status of the project. I have done a bit more after these pictures were taken and I plan to do more work on it tomorrow and during the weekend.
To be continued...
