SDR-IQ is running, with a 20Hz wide waterfall looking in 0.03Hz FFT= bin size.
It took 5 minutes for a calibration signal to show up on the scr= een.
The paint is drying - slowly :-)0

LF,

I shall be transmitting VLF today starting at 09.00 Z

Freq:    8.971 855 kHz (nominal but close)
Mode : Continuous carrier with occasional QRSS identifier
Aerial:  Initially:  40m inverted 'L' at 10m 
           Later: &= nbsp;   balloon supported aerial at 50m

Hopefully the system will keep going as the loading coil re-wind
seems to have done the trick now that the varnish has dried.
