with 40s of RA tuning signal (Waltzing Matilda) at the start of each session.

Extremely poor reception here this morning of 11695. I could barely detect that there was a station there and only a few words were decoded.


The tests have been a success and reports are coming in from around the globe. The Voice of America's Dr Kim Elliot, reports on his reception in Northern Virginia where despite poor audio reception, the digital text message was perfect.
