It is equipped with a 2.4 kHz filter for SSB and a 6 kHz filter for AM operation. It has the RF speech processor built in ex factory.

  Frequency ranges 2200 - 2700 kHz marine band, 80 - 10 meter HAM bands plus 27000 - 27500 kHz CB range and reception of time stations in the 10 MHz range. No 160 meter HAM band. For the marine band - unlike all other versions - the frequency display has a third range drawn on it. This is the rarest version of this model series.
