The problem with searching for a dx station of known frequency with
the Superradio is its analog tuning dial is so inexact. A digital
tuning dial that shows exactly the frequency of the station will at
least tell him he is on frequency.

I've had pretty good luck with the Select-a-tenna loop -- it works
well on weak AM stations IF their frequency is in the clear.

Beyond the Ready-Made AM/MW Loop Antennas like the :
Select-A-Tenna, Terk AM Advantage, and the former
RadioShack AM Loop Antennas. Building you own AM/MW
Loop Antenna is another Option to consider. But If - You
are considering IT; then consider Building IT Big. Takes very
little more work than a smaller size Loop Antenna and
provides much better Results. The minimum Size that I
would recommend for a Home Made AM/MW Loop Antenna
is 18 to 20 Inches. IMHO One Yard (36 Inches) to One Metre
is the Right Size for a Home-Brewed AM/MW Loop Antenna.

BUILDING - One of the Bigger Box AM/MW Loop Antennas :
The One Metre AM/MW Loop Antenna
-aka The Square Yard AM/MW Loop Antenna
These are about as big as you want to get when . . .
considering an AM/MW Loop Antenna for In-Doors Use.

of the Switch Box.
3 - Thread the Hook-Up Wire into the Switch Box
and around the inside of the Hula Hoop 9 times.
4 - Trim off the Extra Wire.
5 - Solder the Wire ends to the Variable Capacitor's
Frame and Rotor.
6 - Drill a 3/8" Hole in the PVC Cover Plate for the
Switch Box and Mount the Variable Capacitor.
7 - Place the Cover on the Switch Box
8 - Tune, Postion and Enjoy your home made
