I know that the Turtle Beach Santa Cruz sound card has been popular among RTTYers. Has anybody tried Voyetra Turtle Beach's new Riviera and Catalia sound cards? Has anybody run the Writelog sound board check program? I would appreciate comments like the ones at http://www.qsl.net/wa9als/sound_results.htm. 73, Masa Miura, AJ3M Bethesda, MD
