BITX40

Technicals

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 16×2 frequency display, free and open source code, 6 analog ports, three oscillators and six digital lines.

Receiver The 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! 

Box Contents

We have tried to include connector/hardware you might possibly need to build a full radio. However, we also had to balance the shipping weight to keep the overall cost down. You will have to supply your own box, power supply and earphones/headphones/speaker.
