Arduino and RF from kHz to 1 GHz

Arduino and RF from kHz to 1 GHz

RFZero have announced the RFzero - a multipurpose Arduino RF and GPS controlled platform, that can generate frequencies from 2605 Hz and beyond 200 MHz.

At the same time 28 I/O pins are available and eight of those are via an ULN2803A power driver.

The typical use of the RFzero is as a beacon (IBP, SPB, CW, FT8, JT9, PI4 and WSPR), Qatari Oscar 100 dual LO or as low cost 10 MHz GPSDO. A dozen example programs (sketches) are integrated into the Arduino IDE.

The RFzero has been developed for radio amateurs, RF enthusiasts and everyone else who wants to extend the Arduino skills in combination with RF. The RFzero board is largely compatible with the Arduino Zero and Arduino M0 boards, however, it has been carefully designed for flexible use in RF applications and with attention to the frequency spectrum and stability performance.

Wolfwave Advanced Audio Processor

WOLFWAVE is an audio processing system designed to improve reception on SSB, CW and data modes. It includes sophisticated digital band-pass filtering, noise reduction and even age-related hearing correction! All these facilities have been designed to help users increase the performance of their radio systems.

WOLFWAVE also includes a useful low-distortion audio test generator that can generate one or two tones for transmitter testing. Another novel feature is an experimental "CW Regenerator" that gives noise-free CW reception.

WOLFWAVE features a bright OLED spectrum display and on-screen help, all powered by the latest ARM low-power processor with a 20-bit CODEC. There are separate audio outputs for headphones and a loudspeaker.

WOLFWAVE firmware is upgradeable so users will always benefit from the latest developments. Such is the flexibility of the WOLFWAVE hardware that other enhancements are sure to follow!
