Anyone know a simple 100kHz crystal calibrator emulator?

There are lots of old fashioned ham radios with xtal calibrators, like the Kenwood 520 and Yaesu 101 Hybrids
You could look at their schematics and come up with one of your own pretty easily.
All these things are is an oscillator with a lot of harmonics that feeds into you antenna input.

The one AZ showed you is quite typical.
There is one in the ARRL question book for HAM exams.
