The rise of internet radio has made it pretty difficult to obtain a really good FM tuner these days regardless of the price.
In fact, I'm not aware of anything with real diversity reception-- at most they're limited to crossfading two tuners, and even that is mostly a car radio feature.
I wonder if anyone has been working on an open source state of the art SDR broadcast FM receiver.
A good receiver would have denoising of the stereo signal, filters to eliminate HD radio interference, PLL/matched demod of the stereo signal, and support diversity reception using constant modulus algorithm or similar.
- xxpor 7y agoIt's a damn shame the Icom IC-9700 doesn't support out of band RX
- nullc 7y agoOr WFM :) IC-9700 is an impressive looking radio. I think amateur VHF/UHF/SHF SDR are really a long way from what state of the art should be in those bands, but are most just porting HF SDR to a new set of bands. VHF+ SDR should be all about beam forming, broad band modes (spread spectrum), digital, etc. There is so much more spectrum available (esp in 23cm), and its so much easier to put up multiple antennas.
