The intent of this project is to turn a HackRF (or other SDR board) into a multi-band transceiver for use in amateur radio contests such as the ARRL June VHF contest. At present it only supports CW.
At the moment, it depends on patches to hackrf and gr-osmosdr to add support for transmit/receive switching:
- https://github.com/argilo/hackrf/tree/allow-tr-switching
- https://github.com/argilo/gr-osmosdr/tree/allow-tr-switching
Usage
Install GNU Radio, and build hackrf and gr-osmosdr using the "allow-tr-switching" branches indicated above. This can be accomplished most easily using PyBOMBS.
The main transceiver application is vhf_transceiver.py, which can be run from the command line. It ties together the receive and transmit flow graphs (vhf_rx, vhf_tx) which are built with GNU Radio Companion. The GUI is part of the receive flow graph.
To transmit CW, type your message into the "CW to send" box and press enter. Once transmission is complete, the box will empty and the waterfalls will start running again.
