Effective 05 March 2012, US amateurs have new privileges on the 60 meter band. In addition to an increase in effective radiated power from 50 to 100 W, hams can now transmit CW and PSK31 on the following channel-center frequencies:
Channel 2: 5348.0 kHz
Channel 3: 5358.5 kHz
Channel 4: 5373.0 kHz
Channel 5: 5405.0 kHz
Channel 1: 5330.5 kHz
Amateurs can also transmit Upper Sideband voice and PACTOR III on the following suppressed carrier frequencies (the frequencies typically shown on transceiver displays):
Channel 2: 5346.5 kHz
Channel 3: 5357.0 kHz
Channel 4: 5371.5 kHz
Channel 5: 5403.5 kHz

The FCC has granted hams secondary access on USB only to five discrete 2.8-kHz-wide channels. Amateurs cannot cause inference to and must accept interference from the Primary Government users.
Also, 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 (see above transmit frequencies).
