Hi,

MUCH better today! The SNR almost topped at 34 dB! But there were several interruptions, sometimes for longer periods. Something's going on .... but what??

Hi,

Here is a log from this afternoon. The usual interruptions are still there
Otherwise the reception is very good here, although I'm not in the target area.

Not worth listening for a prolonged period here. I guess, I'm too close to the TX and too far off the beam as well.

Hi,

Almost three hours of quite good reception except for some minor interruptions in the audio around 11 UTC for some reason. On-channel carrier or AM QRM? Difficult to say without a second receiver.

For a while I thought the irritating dropouts had noe at last disappeared, but around 1215 UTC there were three large dropouts. (If someone proves the opposite, then it might have been my PC running a programme in a DOS window - don't ask why!)

Thumbs up MOBILE RECEPTION

Driving home from near Herford to 48712 Gescher via A30, A31.
Easy listening with 160 on the meter and over 30 on the dB scale.
Suddenly the conditions were gone and the strongest signal left was a carrier 5kHz higher.

Hi,

Switched on Luxy for some time in the afternoon. The reception was mostly OK, except for the usual drop-outs, but not so many today.

Hi,

One hour of solid reception from Luxy. Despite the too low frequency, should have been around 12 MHz, I got > 98% CDA. Time: 12 - 13 UTC.
