This is the very first Patric's post:
>>......I can inject an RF signal at various frequencies down to 500Hz (with var. cap fully meshed), and tune to that frequency, at which point I can adjust both the 1st and 2nd IF cans. But I get nothing when I try to inject the 460 Hz IF.
To me that implies the signal (he uses the same generator, just changing the frequency) is modulated. Else he would not hear either 460kHz or 500kHz and up.
Of course I could've misunderstood that too.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
