Welcome to Tropical band
To most people the phrase "tropical bands" bring a pretty clear picture to mind - a bunch of shirtless guys playing calypso music. But to experienced shortwave DXers those two little words express the most challenging and enjoyable part of the radio hobby. The phrase kindles memories of a DXer's best catches and favorite QSLs, of exotic stations, music and of early morning listening sessions. (Don Moore)
I like the "Tropical band" name for new 60m allocation. (OK1RP)

60m - Tropical band in USA
The FCC has granted hams secondary access on USB only to five discrete 2.8-kHz-wide channels. Amateurs can not cause inference to and must accept interference from the Primary Government users. The NTIA says that hams planning to operate on 60 meters "must assure that their signal is transmitted on the channel center frequency." This means that amateurs should set their carrier frequency 1.5 kHz lower than the channel center frequency.
General, Advanced and Amateur Extra classes:
Channel Center / Amateur Tuning Frequency
5332 kHz / 5330.5 kHz
5348 kHz / 5346.5 kHz
5368 kHz / 5366.5 kHz
5373 kHz / 5371.5 kHz
5405 kHz (common US/UK) / 5403.5 kHz
Amateurs may use USB *only* with a maximum effective radiated power (ERP) of 50 W. Radiated power must not exceed the equivalent of 50 W PEP transmitter output power into an antenna with a gain of 0 dBd.
For details, see the 60 Meter FAQ page.
