RFI 3965 kHz reception near Atlanta, Georgia, USA

Interesting week with boosted propagation on the lower frequencies. This early morning transmission still providing a strong enough signal to generate a few SNR results in the log.

RFI 3965 kHz reception near Atlanta, Georgia, USA

Coditions good overnight with the low power RFI transmission showing some SNR spikes on the log (attachment 1) and a weak signal on the waterfall display (attachment 2).

RFI 3965 kHz reception near Atlanta, Georgia, USA

The signal suddenly rose to 10.93 dB SNR at approximately 0416z, lasted for about 5 minutes, and then disappeared!

Some SNR spikes (max SNR about 6dB) showing up in the overnight log (attachement 1) and the signal clearly seen on the Dream software System Evaluation screen (attachment 2).

RFI 3965 kHz reception Newton, New Hampshire, USA

Some 1500 km closer to the transmitter site, in the North East of the USA, the signal was strong enough for audio decoding!

Their signal has been a bit poor here all week, but is back up to a decent 15.4db SNR this evening.

RFI 3965 kHz reception near Atlanta, Georgia, USA

The late evening transmission shows a much stronger, than usual, SNR for this low power transmission.

I happened to notice that the Dream software synched on another DRM signal 10 kHz below, i.e. 3955 kHz as shown in the 2nd attachment.

Was this an unscheduled test transmission from the Woofferton transmitter?
