FMode,
i totally understand the essence of your work with HQCT. I was thinking this for some time, as why people were trying to write seperate interfaces for each card as there is a directshow interface Microsoft has. By using AMCAP, you can easily use any radio card that have a WDM driver. But does this rule applies radios that are HID compliant, i don't know. I'm a programmer but don't have enough knowledge with C#. If you or David can help me to make a quickstart to write an interface for Silabs using FMRadioHAL, i'll try to make my time.
I can use Silabs with Radiator right now, but with echoes. To silence the second instance of the same channel, i'm pressing the pause button every time i change a channel.
And i'm bored of it. This is the motivation behind the native Silabs driver i'm planning to write with the help of you. And for the first phase i only plan to make the radio work, RDS is later.
