I found this thing in above radio(PC-833) and couldn't figure out who made it. It doesn't have any trimmer caps, which i thought was goofy.

It also looks like it was modded at some point but idk.

I thought it was an expo N board but it doesn't look like the others I have seen and again, no trimmers.

The letters "J" and "T" on each crystal are what the Expo crystals are marked. Maybe some early prototype?

Not one I have ever seen.
