Another odd thing about the use of the name "Tropic" on the radio is that the bands that were designated back in the day for domestic broadcasting in the tropics (with fairly wide coverage at night) are not all covered by this radio.
The Tropic bands were/are:
2300-2495 kc (125 meter)
3200-3400 kc (90 meter)
4750-5060 kc (60 meter)
Instead, this radio seems to be designed to receive the most popular worldwide shortwave broadcast bands.
