Windows bug, verslechtering van ontvangst van digitale modi

Interessant artikel + video met uitleg.

There's a bug with the USB audio chipset used in many ham radio sound interfaces that occurs in windows vista and later. The affected chipset is the TI PCM2900 series, pre-C revisions. A non conclusive list of devices using this chip line are all Icoms with built in USB sound interfaces (7100/7200), all Kenwoods with built in usb sound interfaces (590), and all Signalinks. If you have one of these devices, and are on windows vista or later, your performance is reduced due to this bug even if you think it's working fine. Wait until you see your performance afterwards :) This is confirmed by Texas Instruments, who never recommended this chipset for use on windows Vista and later in the first place, and also tested with more than 15 hams who gained massive receive performance after the fix.

Super info!,

Ik heb het gelijk toegepast.

Ik heb destijds zelf audio interfaces ontworpen met inderdaad ook een PCM2904 er in.
Ik voor elke radio zo'n interface, en inderdaad het werkt nu nog veel beter :)
