I had an AOR AR5000 that I bought used and sold for what I bought it for.
They are a great receiver for scanning. I bought the optional CTCSS board.
I can't really speak to the performance below 30 mHz. If you want a high
end scanner, don't care about the lack of DPL decoder, buy the AR5000 and
the optional CTCSS decoder. If you need trunk-tracking and some of the
other high end features, buy a Uniden Bearcat BC796 and then a separate
shortwave radio. Needless to say, one of the shortcomings of an all-in-one
receiver is you can only monitor one signal at a time. Do you plan on
scanning below 30 mHz or tuning in shortwave broadcasts? The Icom IC-8500
may be an okay job, but it cannot be fitted with a CTCSS board. I also know
of some people that just go out and buy an amateur transceiver, but just use
the receiver portion. I don't know if any of those have all the features
you need, but there are some sound to light transceivers that do pretty
well.
