AIR Bangalore India 7550 kHz reception near Atlanta, Georgia, USA

This evening's reception (last 33 minutes) - no audio decoded, 9.03 dB max SNR.

Meanwhile in New Hampshire, 1419 Km closer to the transmitter, the signal was being received by the KiwiSDR web receiver in Newton at S9+20dB with 100% audio decoding (see attachment 2)!

The decoded audio bandwidth on both channels was just 3 kHz, providing a poor audio quality.

AIR Bangalore India 7550 kHz reception near Atlanta, Georgia, USA

This evening's reception (last 32 minutes) - relatively strong and steady signal - no audio decoded, 12.20 dB max SNR.

Monitoring various KiwiSDR web receivers along the East Coast of the USA showed a uniform strong S9 to S9+ received signal level. The only decoding took place in Massachussets and NE from there.

AIR on 7550 KHz

Hi all,
after a few years break again a DRM log from my side.

Constant strong signal from AIR here in southern Germany
Sound on Channel 2 was mostly usable but still a bit too loud.

Good reception tonight.

Correction to the DREAM log.
The correct start time was 1911 UTC.
Unfortunately, the time in W10 was overlooked to be set correctly to local.
