    Specs from the guys making the kit:

    The Raduino The new BITX40's Raduino is an Arduino Nano powered, small, hackable board based on the rock steady Si5351 synthesizer with a clean 16x2 frequency display, free and open source code, 6 analog ports, three oscillators and six digital lines.

    Receiver Listen to the very clean, crisp and quite receiver. The front-end has a triple tuned circuit that cuts out-of-band signals. The diode ring mixer front-end makes this a crisp receiver that doesn't overload easily. The all analog signal path to your ear provides outstanding signal clarity that is to be heard to be believed.

    Transmitter 7 watts of low distortion SSB provides you with enough juice to have thousands of contacts on 40 meters, daily rag chew and occasional DX chasing. Any common 2 ampere 12 linear volts supply will provide enough juice for this transceiver. Or you could simply run it from a battery!

    I have built this into an aluminum xpc mini tower computer case. The power supply is rated for 14 amps @ 12 volts ( I did internally adjust the output power to 12.8 volts) and I removed the excess power and ground lead so there are one 12v output, 2 ground and one 5v output, the 5volt output is unused but figured it might come on handy for some sort of mod. I have added a large heatsink to the final transistor. The mic is a Radio Shack power mic. Although I never used the mic's built in amplifier. I have done a few mods that include an amplifier keying output, I did the ptt pop mod also. I added a push buton (black) for tuning the antenna. You hold it in the push the ptt and it outputs a cw tone. When doing this the rig puts out 10 watts on my meter thats built into my tuner. The raduino code has been updated to include RIT, Split, LSB,USB,CWU,CWL ,also has a scanning feature and you can set the scan edges.The rig is set up to use an external speaker and has a 1/8" headphone jack. There is also a 1/8" jack on the rear for mic input as I had it setup with a homebrew soundcard interface that has vox keying. I have worked FT8 with this rig.( I would be willing to sell the soundcard interface as well if you are interested I can get pics of it. ($30 additional)
    All you need to get this rig on the air is an antenna setup and an ac outlet.
