Griffin RadioShark Ships - USB AM! and FM - Offer to develop software
Well folks, it seems that after a year and a half of waiting, Griffin is finally shipping their RadioShark usb tuners. This is AFAIK the first pc-based raido tuner that I have seen supporting AM. It's also probably one of the first with a decent internal antenna. It's also unique in that the audio itself comes in via USB instead of hogging up a line-input on your soundcard.
Anyway, I'm posting it here in the software section because there are no non-mac drivers for it as of yet. Due to the audio issue, this may be more complicated than just finding an appropriate usb->serial driver and decoding the protocol. Hopefully the device identifies itself as a standard USB audio device AND a serial port.
I would be willing to do the legwork on reverse engineering this device and publiclly publishing the protocol; however, I do not have the desire to spend $70 on AM/FM radio at this time. :) If anyone wants to volunteer to order one and loan it to me for a few days to try to get it working, I'll be happy to do this and send it back to you when I'm done. I have a mac that I can use to analyze the protocol, so it should hopefully be very straightforward. Please PM me if anyone's interested.
