The  HB-1A MK2 covers the 20 and 40 meter amateur bands.  (30 meters with modification.)  It can 
receive between 5 and 16 MHz.  The IF bandwidth can be adjusted from 400 Hz to 3 kHz, allowing 
reception of CW, SSB, and AM signals.  It can be powered either by an internal Lithium-Ion battery or 
an external power source.

The LCD display shows the following:

Frequency

The 20 frequency storage memories can be used to change frequency and band.  The tuning steps can 
be set to 10 Hz, 100 Hz, 1 kHz, and 100 kHz for the amateur bands.  Outside the amateur bands, tuning
steps can be set to  10 Hz, 100 Hz, 5 kHz, and 100 kHz.  RIT tuning steps can be set to 10 Hz and 100
