The µBITX ‘s Raduino plugs into the main µBITX board. It is an Arduino Nano powered, small, hackable board based on the rock steady Si5351 synthesizer with a bright 2.8 inch, 320×240 TFT display, 6 analog ports, three oscillators and six digital lines. It comes preloaded with µBITX’s free and open source software , so you can add all the features you want to!Listen to the sensitive, low distortion, all analog receiver. The front-end diode mixer followed by a Hayward/Kopski TIA makes this a crisp receiver that doesn’t overload easily. The 45 MHz roofing filter at the first IF and the 8 crystals SSB filter will please your ears with natural sound.

Transmitter 10 watts of low distortion SSB provides you with enough juice to have thousands of contacts on all HF bands. Chase DX on CW, ragchew on PSK31 or work the nets on SSB. Any common 3 ampere 12 linear volts supply or a set of eight AA batteries will provide enough power for this transceiver.

Hackable

To be hackable, it has to be understandable. The µBITX circuit design is simple enough to fit a single page. It’s simplicity encourages you to modify, change and experiment. The µBITX is easily programmable in Arduino’s simple C language. The rig can be uploaded with your own software with just a USB cable. If you made a mistake, just load back the original version from the web! The main board uses discrete, large-sized SMD components laid out in an easy-to-understand manner on a double-sided board with broad tracks. This can be your main module around which you can start experimenting. The kit comes in two flavours:has parts can be installed inside any box that you like. Make your own station rigs, man-packs, SOTA rigs, trail radio or mount it in a cigar box and leave it on your bedside table.comes with a laser cut, powder coated aluminium box, a large 3-1/2 inch speaker to assemble a complete, working transceiver. You only need an antenna and a 12v, 3A power supply to work the world!
