My wife unfortunately broke her arm a few weeks ago and can't drive so I've been away from home looking after her. Normally on a Sunday morning I would conduct a FreeDV RADE V1 net on 7.177.
I tuned in this morning via the excellent Ironstone Range WebSDR and was pleased to hear that stations can chat without my help ;-).
This screen recording was made by using Loopback to pipe audio from the Safari Web browser into my home brew FreeDV app for macOS called FreeDVneo.
Hi Peter
ReplyDeleteVery interesting video clip!
VK5AG was transmitting with AM modulation. There was a carrier not sure if full or reduced. I decoded him on both USB and LSB. Didn't think at the time to to try AM or record for future analysis.
His USB was slightly lower level but still significant and easily decoded.
I don't think Steve was aware of his AM Transmission.
Note the LSB, carrier and part of the USB is clearly visible on main screen behind your decoding screen
The other station in your video clip I believe is VK5ADE not VK5DE
Keep up the good work.

Ah yes, that explains the very wide signal: AM, or perhaps double sideband?
