How many bands of frequencies are hams allocated?

The FCC has granted hams secondary access on USB only to five discrete 2.8-kHz-wide channels.

What is the best HF band?

In general, the lower bands, 80 and 160 meters are best at night because of daytime D layer absorption. 30 and 40 meters typically work both night and day but daytime distances are limited because greater distances require lower propagation angles, which, in turn, mean longer paths through the D layer.

Which ham bands are USB or LSB?

When operating an amateur radio station using SSB, there are choices for upper and lower sideband. It is generally accepted that Upper Sideband, USB is used on frequencies above 10 MHz and that Lower Sideband, LSB is used in frequencies below 10 MHz.
