Heard in Farnborough

[MelMartin2]

I heard the transmission yesterday using a e-field probe at about 20ft high with earth spike and Spectrum lab software on a laptop.
Difficult to make an exact measure of the signal to noise but probably of order of 3dB or more.
I noticed some instability in transmission frequency towards the end.
At start it was very stable.
Difficult to give exact figure but looks like + or – 25Hz on Spectrum lab waterfall display.
A distinct slow wiggle as your system brings it back to the centre frequency.
I have a photo but not sure how to add it.

24th October 2023 I recorded the SAQ message of peace transmission using the Twente SDR and played it back with Windows Media Player boost 1kHz +12dB and at times ½ speed. On a previous occasion Norman, G8ATO of Verulam ARC suggested that the operator may be using commercial Morse that includes characters I’m not familiar with. BT = break.
