Thank you!
I need to group, organize and digitalize the schematics of all stages of circuitry, because I have it write down in drafts (paper) and some parts are on my mind.
Sure, I will publish and share the as built schematic of this radio as soon as I have finished this work.

Most excellent. Could you publish details so that others can duplicate this receiver?

It is possible. First you need the schematic of radio an locate the local oscillator. Then you may pick up the signal of local oscillator coupled via 1pF capacitor to a RCA or BNC connector. Eventually, you will need to install a transistor buffer inside the radio, to amplify this RF signal.

Would there be a way of connecting a frequency counter to an earlier model of shortwave radio? Such as, the Realistic Dx-200 or a Knight Star Roamer?

Nice workmanship.
