Combine a pasta strainer with a Software Defined Radio and you get a SDRainer. It separates all the tasty CW signals from the ether:
- decode a CW signal from a Pulseaudio source
- find and decode CW signals in an IQ stream coming in through the TCI protocol
- show the spotted callsigns as spots on the TCI device's spectrum display
- provide access to spotted callsigns through a telnet connection, like a local DX cluster
This is work in progress, the CW decoder is still a bit inaccurate for weak signals.
Decode a CW signal from a Pulseaudio source:
sdrainer decode pulse
Decode a CW signal at the VFO A frequency of a TCI device:
sdrainer decode tci
Detect and collect callsigns from a TCI device's IQ stream:
sdrainer strain tci
Use sdrainer --help or sdrainer <cmd> <sub-cmd> --help to find out more information about the supported parameters for each command and sub-command.
- send spotted callsigns to a dx cluster
- add support for other SDR devices (KiwiSDR, HDSDR, SDRplay, RTL-SDR, IC-7610, FlexRadio)
- add support for other digital modes (PSK31, RTTY)
I started this just to scratch the itch of learning how a CW skimmer might work. If you like what I'm doing here and want to support the further development, please consider becoming a sponsor of this project.
