SWL tuning an MFJ loop?
 

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!

Without going through their catalog, the only loop I am familiar with is
their amateur magnetic loop- whose response from memory goes down to
perhaps 30M- but not below. Is this the loop you are considering, or do
they now make a SW receiving loop?

Tune it for maximum noise or signal on the frequency. You should hear
the motor noise on your receiver as the capacitor turns. Then fine
tune it back and forth.

Hello

Tune it for maximum noise or signal on the frequency. You should hear
the motor noise on your receiver as the capacitor turns. Then fine
tune it back and forth.

Right, just tune for max. noise or signal, please notice that some loop,s
are
very sharp and have a very small bandwidth. And if you can hear the motor
turning the capacitor, then return the antenna to the manufacture and tell
him to design his products properly.
