Default FM portable radio

I, new here and sorry for my poor english, I, was wondering if a High quality portable FM radio does exist! I'm actually using my HD Zune FM radio (with cMoy v2.03 & Atrio M5) at work, but must often listen to music unstead because of bad frequency & high distortion. I'm a cMoy v2.03 portable amp user and read a lot about portable amp, so wonder if FM portable exist?

Thanks,
E-Audio

Yes, search for a single chip TDA1083, it includes from FM if to audio output, only need two BJT´s for FM mixer. I did some of it 10+years ago, and great performance.

Can you explain more, I'm mostly using pre-built, as I've no electrical formation and tools.

Good sound quality FM receiver are not easy DIY items..

Best would be to use a cheap cell phone with integrated FM radio
as the NOKIA ExpressMusic models , get a used one, it s enough for
the purpose.

See : FM/AM Tuner

5V power, simple enough (datsheet schematics), sounds fantastic.
Most modern-day single-chip FM receivers that I came across sound terribly in comparison.

If you are trying to listen in an electrically noisy environment, there's probably no practical solution to improving the radio reception.

Since almost all these portables use the headphone cable for the antenna, have you tried different interconnects between your Zune and cMoy? The reception of my Cowon J3 's FM tuner depends on headphone model for example. Before buying something different you might want to try experimenting with an unshielded interconnect made from lightly twisted wire first.
