The sBitx is an open source, high performance Hybrid SDR for the 21st century radio amateurs. Powered by an internal Raspberry Pi 4, it has CW/RTTY/PSK31/SSB and FT8 with logging software, macros, spotting in-built.

 

 

sBitxV2 - First Look
  • The big compact : Although compact, it has the largest display shipped with a transceiver, a capacitive, touch screen of 7 inch.
  • All software to run modes like FT8, RTTY, PSK31 is integrated into the radio, without any messy configurations, setup, etc. to deal with.
  • It switches soundlessly from transmit to receive and between bands due to its electronic of filters and T/R,
  • Band-stacking VFOs with 4 memories on each of the 8 bands, 9 convolution digital filters for the best audio experience.
  • High performance electronics with a passive-FET front end, 8 crystals’ filter and a low phase noise, temperature compensated crystal oscillator.
  • The built-in, editable macros that make it a breeze to work DX or compete in contests.
  • Add an HDMI monitor or use the browser from your PC/tablet to have a large screen experience of all the features of this amazing radio.
  • The sBItx will neatly slip into your backpack with its compact, slim size of 10 inch x 6 inches x 2 inches and weight of under 4 pounds (less than 2 KGs) with room to spare. With its 40 watt transmit output, it is the most powerful radio you can put into your backpack.
  • It is armed with an XT60 power connector that you can use with lightweight 3S LiPo batteries to provide hours of field operation (The receive current is 600 mA, the transmit current can go up to 8 A depending upon the drive settings).
  • The built-in mic and the onscreen keyboard, macros makes it easy to operate all modes, voice/digital or CW without a key, mic or an extra computer in the field.
  • It has an accurate real-time clock to time FT8 transmissions and log the contacts made.
  • The built-in logger eliminates the need to carry the logbook too.
  • Bulletproof hybrid superhet with passive-FET KISS mixer
  • Brickwall crystal filter with  8 crystals
  • 80 db close-in dynamic range, 90 db wide dynamic range
  • Low phase noise, temperature compensated reference oscillator
  • 30-40 watts output on all bands from 80 M to 10 M
  • transmit IMDR of30 dB (from PEP levels)
  • Silent, fanless operation
  • Noiseless electronic T/R and band switching.
  • In-built 2-tone transmitter to tune the antenna and measure IMD
