A Small Loop Antenna for Receive Only (ver. 2)
Changed the shape and the coupling method.
I intend to use the antenna on 30m band, but perhaps more fine tuning is required.
Comparing my reports and my neighbour’s for the last 12 hours.
UDP audio stream from Gqrx (4)
A Python program to receive UDP packets and to play sound.
UDP audio stream from Gqrx (3)
A Python program to display the audio signal waveform in realtime.
UDP audio stream from Gqrx (2)
Suppose you are listening to a CW station, and at the same time streaming the audio signal.
You can get the waveform of the signal in the following manner.
The UDP packet size differs a lot.
UDP audio stream from Gqrx
Gqrx has an option to stream the audio over UDP with the following specifications:
- Channels: 1 (left)
- Sample rate: 48 kHz
- Sample format: 16 bit signed, little endian (S16LE)
The audio stream can be received, for example, with the following Python program.
Report interval from WSJT-X to PSKreporter
The Display Reception Report of PSKreporter is automatically updated evert five minutes, but you may wonder how often your WSJT-X program is sending report to the site.
It may help to ask Google, but reading the source code could always be a better way.
O.K. It says it’s every five minutes.
The timer is set to 300sec.
The port 4379 is used as is mentioned in the following document from PSKreporter.
Finally, you will check with Wireshark.
Yes, it’s every 300sec.
