Biggest signal yet and audio!

A good night for me on this one! 22.2 SNR high. 10 minutes of audio over the broadcast. Journaline loaded with some data error however. I could see the broadcast on the waterfall up until it went off air.

Very poor here. I could see the signal on the water fall at 0530, but the signal was so poor it did not even record on my logging program.

Nothing here last night. Propagation is certainly very irregular, but then I'm asking for something that is nearly impossible.

Just for a casual listening trial. Because I've moved to new place, not all the equipments are properly aligned yet.

This is the channel profile. Quite long IR, despite of strong signal. Maybe this is due to the window facing direction(north facing)?

I don't know the test result for the target zone. Here is no quite good:when signal is strong, long IR. Otherwise constant flat fading esp. on 21640kHz.



Maybe the solution is to use SFN or MFN to improve stability,if they don't want to sacrifice service quality.I can make some changes to the Dream source code algorithm to combine bit informations from different channels in order to improve service quality.
