*1 MAIN BAND: Spec. guaranteed in amateur band 160m through 6m
*2 In 160m/80m/40m/20m/15m Amateur band, IF band width 2.7 kHz or less (SSB, CW, FSK, PSK)
*3 Except in above *2

Internal beat may occur during amateur radio band reception depending on combination of main band and sub band frequencies of a main unit.
Spurious signal other than reception signal may appear on band scope (waterfall view) too.
