Windows 10 laptop, transmitting @ 8 Khz on VLF band, QRQ CW @80 wpm - Received on Linux Laptop using SAQrx SDR RCVR

this is a follow up video to the first one:
https://youtu.be/ON-tZWiCCPQ...

everything is the same in this video, except, this time we send QRQ CW at 80 wpm to test how it will sound over VLF and using SAQrx by itself - using its 300 hz wide bandpass filter - centered at 700 hz
and with both laptop's wire antennas, arranged & positioned better for optimum signal TX::RX

both laptops are using simple WIRE ANTENNAs connected to...
- WIN 10 TX - headphone audio output jack
- LINUX Lubuntu 18.04 RX - USB LINE INPUT
