[Discuss-gnuradio] Success (kinda)

[Alan Gray]

All,

I've been working on putting together a circuit to use the
microtune 4702 tuners I have and I think I've almost got it
nailed. At the moment I'm sampling the 36MHz IF at
20MSample/sec which aliases the centre to 4MHz (reversed). I'm
just trying to demodulate and listen to FM signals currently,
however they're not sounding incredibly great.

I had a quick search through the archives here and found a
thread on "Why FM doesn't sound good" so before I go nuts
trying to figure out just why I'm not getting a good sounding
audio stream I thought I'd ask just now "not good" FM sounds
using the other hardware. 

Basically what I'm hearing sounds like a radio which is tuned
to about 50KHz away from the actual carried frequency. I can
make out beats and baselines but it sounds as if I'm missing
the high end frequencies. I can make out when words occur, but
again they're very distorted and it's hard to determine what
is being said.

Is this consistent with the results obtained by others or do
you get a clearer output? If others do get a clearer signal,
can anyone suggest a possible fix?

Thanks
Alan
