Please consider this a newbie question. Am an SWL, not a HAM, and am
considering an MFJ loop as the primary indoor SWL antenna, along with
an active antenna as a less potent secondary, the two connected via an
antenna switch.

So lets say I read in a schedule that a certain frequency in the 49
meter band right now should have an interesting broadcast station on
the air, so I set my receiver digital readout to that freq, then
what's the procedure to tune the loop to that same exact frequency,
having no transmiter?

Thanks for any help!
