Anyone have one of these and do you recommend. It looks like one of the
old Lowes to me.They were pretty good.Are the C or CC models worth it?

Beats me. I have the R30CC and haven't tried the bare R30. The Collins
filters are very sharp, to the point where there are varying degrees of a
"whoosh" sound like on a good CW filter. However, the AM-mode Collins filter
is supposed to be narrower than the AM-mode Murata filter to begin with--that
is, at -6dB as opposed to -60dB--and I'll say that the AM-mode Collins filter
is very good at keeping adjacent stations at bay. I find myself tuning +/- 600
Hz to improve the fidelity of a station, which in the end beats not having that
wiggle room.

The sad thing is that you have to get both Collins filters in order to get the
AM-mode filter. The SSB filters are said to be a lot alike in performance. I
simply concluded that I had enough radios with broad filters, and it was time
for a change. I didn't expect the filters to be this tight, and it took some
time to get fully used to it.

Otherwise, I agree with most of what the other posters have stated. A
departure from one post, though: You can get the R30 to overload with a good
enough ground and a short enough antenna plugged into the high-impedance jack.
That said, the longwire that I used on vacation was something like 330 feet
long, and I had no overload problems and excellent mediumwave AM reception.
[Shortwave was great, too, but it was my luck that President Reagan died on the
first day of my vacation, so I felt the need to do daytime AM DX.] In an area
where my Sony ICF-SW7600GR--not a bad AM receiver by any means--could hear only
four or five AM stations without a Select-a-Tenna and maybe 70 stations with
it, the band was pretty much full on the Palstar.

If there was anything that surprised me about the radio, it was the SP30
speaker that I bought with it, well worth the sixty bucks or so. If I had to
do it over again and had to choose between tighter filters and having that
speaker, I'm not sure what I would do.
