Ok, guys,
it is one, when you changing the search frequency. Your oscillator maybe fine working, and after long-long time you retuning correctly the receiver coil.
It is good, but what is it the R-C filters, and (for examle) what is the parts of about opamps? Anybody recalculate its according to new freq?
I think, if you not changing these parts correctly, the result is worse, no better.
