Hi Joe,

we are constantly LURKING around 8270.0075 Hz! QRN will calm down in the weeks to come.

The DL0AO grabber is now running a 21 uHz (13.2 h) spectrogram on the cardioid but nothing significant has yet appeared. The tree in Heidelberg is currently "busy" at night with Stefan's EbNaut experiments to RC4HAA but clear in the daytime. I hope that the Cumiana.spectrogram will soon be shifted slightly to also include your frequency.

If your carrier has been continuously on air with constant phase, we could try to stack the carrier from multiple nights, using FFT export data which are regularly being saved by our grabber instances. But I haven't attempted this yet.

To be successful, we'll need each and every available microwatt from the transmitter - think you mentioned a while ago that your ERP has been increased?

All the best,
Markus (DF6NM)

Hi Roelof and Graham,

The 'big RL' (100 long 20m h) was feeling neglected so it was fed 40 watts
of 630m Opera. The show continues tonight. Thanks for the reports.

Meanwhile on VLF, the TX has been on since the last EbNaut TA and the
phase should be quite stable with the pickup antenna feeding SL.
If the carrier is good, another (longer) message will be attempted.
A character or 2 to Germany will be next goal.

Paul Niclolson's UBX code for the NEO7 is remarkabke. Thanks Paul.
