HB-1B MK3 2015 is the upgrade version of our HB-1B QRP transceiver. It is a small in size, light weight, lithium battery pack , particularly suitable for travel, picnics and other outdoor activities. HB-1B MK3 covered 40m,30m,20m,17m and 15m amateur bands.With the DDS circuit to generate VFO signal, it can also work outside of the 5 amateur bands.
It can cover between 5.9-22MHz band short wave radio bands. Additional IF bandwidth switching adjustable 400-3Khz continued, you can receive a good SSB, AM and CW signals. HB-1B MK3 LCD display: frequency, operating mode, supply voltage, S meter, receive fine-tuning (RIT) and forward and reflected power level, It is very convenient to use. HB-1B MK3 have 30 frequency storage memories can be convenient to change the operating frequency and band.
Frequency step Can be easily to change, amateur bands: 10Hz, 100Hz, 1KHz, 100KHz. Radio frequency bands: 10Hz, 100Hz, 5KHz, 100KHz. Receive fine-tuning (RIT) has the step 10Hz and 100Hz. Specifications Size: 132*85*35mm (not including knob, etc.) Weight: about 380g (not including battery pack)
