The P400 operates on 40 AMchannels, 40 Upper Side Band channels and 40 Lower
Side Band channels.

When transmitting on SSB, there is no carrier and only one sideband is on the air either

upper or lower. Your receiver can hear this sideband signal but can't change it into us-

able information in the AM mode. You can recognize a side band signal being received in
the AM mode by its fluttering unintelligible sound. A signal transmitted on upper side-
band can only be properly received with the mode selector of your transceiver in the up-
per side band position.

When you receive the SSB signal inthe proper mode, audio sound may be either too high
pitched, or Iow pitched, indicating that your receiver may not be tuned to the exact same
frequency as the transmitter it is listening to. The P400 is equipped with a Clarifier. By
tuning the Clarifier, you can slightly change the frequency of the receiver. So, you can
get a normal tone.
