Here is mine: (from this morning's QSO with w4dbv)
the FLrig APP controls the rig from my remote position in the living room...
the lowpass filter shown - also acts as a CW PEAKing filter operating at 680hz... i have found it to really help out and perform very well as an audio cw bandpass filter
from CALF STUDIO GEAR - https://calf-studio-gear.org/
this remote system operates at low latency, no delay is noticed from typing on the cw keyboard and hearing the sidetone from the rig this remote system also operates in full QSK mode...
this system is using Gstreamer pipelines to get the RIG AUDIO back to the remote laptop over ip via an rtsp server on a pi 4 that is connected to the K3S... the k3s has its own usb sound card, and the pi4 is using the k3s usb sound card as its own sound card....the pi4 initiates an audio over ip LAN/ETHERNET setup and sends the audio to the laptop
the cw keyboard shown is actually on the PI4 and the pi4's CW KEYBOARD sends its CW AUDIO to the RIG's LINE INPUT(same usb sound card) and keys the rig via AFCW MODE on LSB.... to get the cw keyboard to show up on the remote laptop, "ssh -X" is used to get the PI cw keyboard on my laptop desktop so i can type on it... the cw keyboard is from Recri Keyer https://github.com/recri/keyer
the OS of the remote laptop is Lubuntu 18.04
the laptop is an i7 quad core
the audio engine is JACK AUDIO CONNECTION KIT
