LIVE HF RECORDING of a QRQ CW QSO between W5UXH & K6KX

Original audio file provided by W5UXH... what you are hearing on this video is the re-recorded audio file, using an AGC APP called VLeveL and an LV2 PLUGIN called "simple scope" to provide a comparison of the orignal(green) and the VLeveL'ed (RED) audio wave forms...

SCOPE - green on top is original audio from the w5uxh file,
SCOPE - RED on bottom is AFTER it is processed with VLeveL

FROM: W5UXH
"FYI: This recording was originally recorded by W5UXH as heard on the K3, in qso with K6KX, I forget if we were on 30M or 40M. It is possible we began on 30M and moved to 40M during the qso. The first signal heard is K6KX over the air, the second one is my sidetone from the K3. At some point we both went up to 75 WPM and it is obvious from our keying that we are not able to keep the fingers running that fast and we do not type ahead in the buffer at any speed, so lots if .. .. (double I) for errors with backup to fix the typo after the fact, and lots of words that do not flow easily from the fingers, so long spacing between characters in those words."

Here is a LIVE  'off the air'  recording, of a QRQ CW NET on 80 meters(10-29-2017)

audio recording of an HF 80 METER CW NET that took place on October 29, 2017... (audio was recorded from the LINE OUTPUT of an Elecraft K3S connected to the LINE INPUT of a USB SOUND CARD on a Linux computer)

QSB was up and down quite a bit, and the HF background static was high, - the K3S 250 hertz cw filter was in use...

Here is a LIVE 'off the air' recording of a QRQ CW NET on 40 meters (4-14-2018)

audio recording of an HF 40 METER CW NET that took place on April 14, 2018... (audio was recorded from the USB LINE OUTPUT of an Elecraft K3S's own sound card, and connecting to the LINE INPUT of another USB SOUND CARD via "audio OVER ip" on the local wired area network, to a remote Linux computer)

NOTE: the HF Receive audio was transferred over an "audio OVER ip" APP called Zita-njBRIDGE to a REMOTE RIG AUDIO Linux laptop receiver, where this recording took place(Lubuntu 16.04 64 bit)
A raspberry PI was used as the "audio OVER ip" transmitter, by connecting a USB CABLE from the PI to the ELECRAFT K3S USB PORT
