Скачать или смотреть VLF TRF receiver using HI-FI AM detector - picking up an RF over IP 12 Khz CW transmission

using Gstreamer scripts to send & receive, RF over IP, AM MODULATED CW, at 12Khz, to a TRF RECEIVER that is interfaced with the RECEIVER PC's headphone output jack....this is what the CW sounds like from the TRF circuit using this HI - FI AM detector - http://g3ynh.info/circuits/hi-fi_am.html

this is the first test in setting up 2 raspberry PI transmitter/receivers for a 2 way, full duplex, RF over IP(using gstreamer scripts), CW QSO...being able to use PADDLES, STRAIGHT KEY and CW KEYBOARD(via ad5dz's "RECRI KEYER" GitHub software suite)
(HERE IS THE FOLLOW UP TEST using 2 piez -    • 2 RASPBERRY PI transmitters/receivers to Q...   )
