The high solar wind speed tonight did not work in favour of AIR...

92% decoded audio despite high solar wind for a second day. The log is short because it was not much to listen to in the hum and noise.

This is absolutely not worth logging, not mentioning listening too! Unfortunately I had to zip the mp3, as the Forum does not accept mp3 files...

I was reluctant to report this result but finally I did it.
An hour log at ~98% CDA.
I wonder if anybody is monitoring the audio signal...
Listen to the mp3 inside the zip file accompanied by an another plot.

Hm, I don't understand why they don't add any hum to the 7.55 MHz DRM TX? It just does not produce the AIR feeling without noise and hum !!

:rolleyes:

For some reason unknown, the audio on the test transmissions on 7.550 MHz are completely free from hum and noise!

Hi,

I gave 9950 kHz a try, since I did not get any sound on the 7550 kHz transmission.
Russian Service is the label, but despite the awful sound it sounds English to me. ;)
Quite good reception 19:11 and 19:42 UTC with a CDA of 50 %.


All times are GMT. The time now is 21:16.
