Re: [LPFM] Interference

It's not the Japanese radios that are at fault.  I have one and it's one of the best receivers I've come across.

It's more likely the band expanders that people use that kill all sense of reception accuracy.

Is it possible you are tuning in on Japanese import Car Radio and the
interference is caused by another station multiplexing onto your
frequency via a 10 12 0r 14 mHz split on a car radio... perhaps it's
only Jap import radios having grief with receiving you?

Cheers
