2 Python APPs, a raspberry pi TCP server, OP's laptop, for low latency REMOTE RIG AUDIO over TCP/ip

[Chuck aa0hw]

using a modified PYTHON SCRIPT from: https://brettviren.github.io/pygst-tutorial-org/pygst-tutorial.html this video shows a send & receive CW to and from the RIG PI INTERFACE example... by RiG/Pi TCP SERVER(pi2b) & REMOTE LAPTOP tcp/ip clients

NOTE: this demo is using an ancient Pi2b -even better performance would be experienced by using a pi4 for this setup REMOTE OP's CW KEYER apps for Straight Key, paddles, & CW Keyboard are from RECRI KEYER - https://github.com/recri/keyer + the Recri embed code for operating the TEENSY USB MIDI BOARD that the Straight Key and paddles are hooked up to....paddles/key presses produce midi notes from the TEENSY USB MIDI BOARD that go into the RECRI KEYER software and key's the software CW KEYER's and CPO's NOTE: the PTT tone goes ahead of the CW tone to activate the RIG's vox circuit to turn on the TRANSMIT for LSB before the CW note arrives... the CW notes is delayed just enough to allow the PTT tone(5555 hz) to get the RIG into transmit 1st...then the CW note arrives and is transmitted without getting chopped up...

NOTE... the RIG has a brick wall low pass filter at 4000 hz NONE of the 5555 hz gets through to the antenna ...but the RIG's own TX audio line input monitor passes the 5555 hz tone back to the OP over the audio feed....and needs to be BANDrejected by the filter shown in the CATIA CONNECTION BAY...
