using a variable PULSE GENERATOR Gstreamer script - to help adjust in realtime, a CW Bandpass Filter

[Chuck aa0hw]

Gstreamer Script used in this demo:

gst-launch-1.0 -v audiotestsrc wave=ticks apply-tick-ramp=false tick-interval=100000000 freq=2000 volume=0.5 sine-periods-per-tick=40 ! audioconvert ! autoaudiosink

also being shown in this demo is CW REGENERATION, using ZAMGATE in sidechain mode

NOTE: the recording laptop's Gstreamer version was too outdated, and does not contain the full array of Gstreamer elements that are needed to adjust the pulse generator frequency and timing...so a PI2 with the latest pi-os was used instead as the source of the pulse generator Gstreamer setup...
