[PVR-350] : AM Radio Tuning
Hi all,

I'm trying to make an AM / FM recording system, based on MythTV and, of
course, ivtv drivers :)

I have a Hauppauge WinTV PVR-350 dedicated to this task.
FM radio works like a charm, sound is great, and device is really stable.

But, I can't manage to make AM tuning work, and that's a pity, because I
know the tuner can handle it : I can listen to AM radios using MediaPortal,
on Windows XP (I simply have to tune to 0.585, for example)

When I try to set ivtv-radio to 0.585, it truncates frequency to 0.58, and
more important, it doesn't work...

Would it be possible to patch the ivtv-radio program, or/and the ivtv driver
in order to support larger frequencies range ?

Thanks in advance for your help,

Best regards,
Guillaume.

I'm pretty sure the PVR-350 (and all ivtv-based cards for that matter)
does not support AM. The radio tuner is FM only to the best of my
knowledge. So I'm afraid this isn't going to work.

Hans

Thanks for your answer Hans!

Sure, this card is pure FM natively, but curiously, it can tune to AM
frequencies, with Windows XP driver, at least.
So, I'm confused : if I set an AM frequency for ivtv-radio, let's say 0.58,
will the tuner try to tune, or will it skip because it's out of FM range ?

It is desperate try though, I'll sure get another hardware to support AM :)

Best regards,
Guillaume.
