Hi, I am curious. How can you tune in to 1720 kHz? My AM radio only tunes up to 1710 kHz.

Nearly all modern shortwave receivers will tune to 1720.

If you have a synthesized radio, you can warp the reference oscillator just enough to reach 1720.  In a conventional superhet radio, you can adjust the padding caps on the main tuning capacitor to reach up one channel.

..Or you can use a general coverage receiver :)

Or I can just punch in 1.720 Mhz, right?
