QRQ CW test - send CW at 96 Khz on the LF band at 96 wpm and send it to another OP over IP

[Chuck aa0hw]

brief experiment to see if by using the maximum sample rate of a sound card, 192Khz, would allow sending QRQ CW at 96 Khz(the highest frequency possible at 192Khz sample rate) at 96 wpm

Gstreamer scripts are used by the TRANSMITTER and RECEIVER
- TCP CW LF RF over IP -

TRANSMITTER:
****************
gst-launch-1.0 -v jackaudiosrc ! "audio/x-raw,channels=1" ! audioconvert ! tcpserversink host=192.168.1.137 port=7007

RECEIVER:
***********
gst-launch-1.0 jackaudiosrc ! queue ! "audio/x-raw,channels=1" ! audioconvert ! audiowsincband mode=band-pass lower-frequency=650 upper-frequency=850 length=700 window=hamming ! audioconvert ! audioamplify amplification=1.025 ! audiorate ! queue ! jackaudiosink

for the TRANSMITTER - the CW is sent at 96 Khz directly by the AD5DZ CW KEYBOARD

for the RECEIVER - the 96Khz CW is demodulated and filtered into a typical cw note pitch by the AD5DZ SDR APPs
