KS,

Take the 'portable' AM/FM Shortwave Radio out-side the
House or Building during the late night or early mornings.

Use only the 'portable' AM/FM Shortwave Radio's built-in
Whip Antenna.

Tune around the Longwave (LW) Band and try to hear any
of these Longwave (LW) Radio Stations on this List :

IMHO - Since you are in Europe - You should be able
to Hear a few of these Longwave (LW) Radio Stations
by simply using the Radio's built-in Whip Antenna.

Next try using the Reel {Roll-Up} Antenna out-side
1 - Plug the Antenna Plug Half-Way-In and Tune around
the Longwave (LW) Band to see what you can hear.
2 - Plug the Antenna Plug Fully-In and Tune around
the Longwave (LW) Band to see what you can hear.

Once you have found that you can "Hear" Longwave (LW)
Radio Stations 'out-side' the House. Next try the same
in-side the House with the Radio next to a Window using
the Whip Antenna. Then Hang the Reel {Roll-Up} Antenna
out a Window connected to the Radio as in #1 & #2 above.
