[R-390] OT: Other Radios You Like

[Masters Andy]

Tim raises a good point about his WJ.  I have
thoroughly enjoyed this discussion because I always
wondered about a lot of the radios mentioned. 

Where I live, near Memphis, TN, I have an acid test
that I use to evaluate selectivity.  We have a local
high power AM station on 640 Khz (WCRV), I take the
radio and then tune it to 650 Khz (WSM in Nashville,
TN).  If I can hear WSM and NOT hear WCRV, the radio
is good.  WCRV watches its modulation and is a good
test.  My R390A did not pass the test but a 651S-1 and
the new Flex-Radio I have tried did so with flying
colors.  Others to fail were the IC-75A with the Kiwa
mods, a 51S-1, IC-756PRO II/III and my old
Sparton-although the Sparton with its loop antenna
built in was able to reject 640KHZ by simply turning
it to null the local station.  When flying WSM used to
be a clear channel station and we could use them as a
NDB from hundreds of miles out to thousands of miles
depending on time of day.

My other test is purely subjective and that is the
sound of the audio.  My R390A  has the Kleronomos
audio mod and the audio sounds fantastic out of it. 
The Sparton has been modified to a single ended 6V6
biased in class A and it has the edge on sound.

I figure you guys have collectively saved me $1000's
on what I always wondered about.  THANKS!
