Frequency discriminator and all-electronic receiver

[Mike(Mont)]

I found it a while back but my printer was running out of ink so most pages are illegible. Basically you take the AM radio station in kHz and multiply by the frequency factor. The answer is in kHz and this is what you tune the receiver to. AS I recall fist-sized targets and larger from maximum 100 meters. He said it was a super-het receiver. Also said if you don't have a good AM station you can use the naval VLF station and tune directly to that frequency. He gives no details on receiver construction.
