Captain, if you have a solid state short-wave radio with a digital frequency display you can use that as one way to check the accuracy of your new generators.

The RCP generator looks like a pretty nice vintage piece and with the existing RF lead might be the easiest to start with since the other leads are just banana Jack's.  Also, I'm not positive, but the modern banana plugs from China might be a tad smaller than the vintage ones, but I might be wrong about that.  Good luck.
