Which tuner to get and getting the most from it. Thank God, for the radio!

RE: Quiet MPX decoder

Hi All,

The hiss on KBAQ-FM really was driving me crazy. So, I built up a multiplex demodulator based on the LM-4500A and installed it into my aging Realistic STA-2000 receiver. This indeed takes care of much of the hiss problem. Next will be the installation of a better antenna system. I live in an apartment, so it can't be too large. But it really needs to be outside to work well.

I couldn't afford the nice board that Bob Fitz makes available (www.FMMPX.com) so I built it on a clad perf board from Radio Shack following the basic information on the National Semiconductor datasheet. It looks really home-brew but works and sounds great.

I hope that this helps someone get cleaner sound from their tuner or receiver.

Best regards,
Bruce Sherman
