  • Perfect Radio Australia logo despite marginal shortwave reception (updated)

    As this audio of the Radio Australia digital text test on 8 June 2013, 0850 UTC, on 7410 kHz demonstrates, reception in northern Virginia was marginal.

    Nevertheless, I had 100% copy of the MFSK16 and MFSK32 text. And, using Flmsg with Fldigi, this Radio Australia logo was received:

    That’s actually a replica of the Radio Australia logo created by way of html. (Not very many organizations’ logos can be replicated in such a way.)

    The ABC logo, which had to be sent as an MFSK32 image, was less crisp:

    The slant probably means that I have to calibrate my sound card.

    Update

    Reception of Radio Australia was fair-to-good 8 June at 2150 UTC on 21740 kHz. Amazingly good for 16400 km.

    Reception on 9 June at 0850 UTC was poor on 7410 kHz, thus excellent for testing the text modes. MFSK16 and 32 were received 100%, as was the html Radio Australia logo. The ABC logo as an MFSK32 image was French Impressionist:

    Much better reception and crispness at 1230 UTC on 12065 kHz:
