You fail to describe what "cannot perfrom as well" really means. So
"obviously defective" doesn't really say anything.

as my old Sony ICF6500.

I have two questions.

1. Is a working srii that much better than this sony?

How do you define better? What capability do you need to be better for the
radio to meet your needs?



I have no idea. "SUperradios" often seem to be a kneejerk reaction,
something to mention when someone asks about a "good" AM receiver. But
there is a limit on what can happen, and then sometimes it turns out
people are talking about the quality of the sound, which the SUperradio
likely is better at than many radios, because it has a large speaker
and/or multiple speakers (I think depending on the specific model
number). They are fairly generic radios, no cutting edge design, I
thought they
didn't even use ceramic filters in the AM section. But they have a
longer loopstick antenna than many radios, which may be more important
than a lot of things, and I thought a stage of amplification before the
mixer in the AM section, which many radios won't have (but that's an
incomplete comparison because any decent portable shortwave receiver
will have a decent receiver, and whatever the shortwave design, that
will apply to the AM broadcast band.

2. Is there a technician/company of known repute that repairs these
srii and what would it cost?

There is a page or two somewhere (I don't have a URL) that offers a
schematic and service manual, and tips about repairing and modifying the
radios.

and then...

I see new radios pretty much all have digital tuners. When tuning
these,
do they all quiet as you tune?

No, not all of them mute as you tune.

I had a digital tuning radio - now at
the bottom of a lake - which did so. I found it very hard to scan for
new stations as I had to stop at each new freq. to allow the thing to
produce audio. Do all digital radios act this way?

YOu're looking at it wrong. The radios lock and unlock as you turn
them,
so tuning fast, you'd not hear anything good anyway. The muting is so
you
don't have that junk. SOme radios people have found ways to disable the
mute, but you aren't going to get the same tuning as with an analog
radio, you still have to wait for the receiver to lock up again on the
new
frequency. I suppose some are better than others, though if they use
common ICs there won't be much variation. IMproving lockup time can be
done, but at a cost.

Michael

Thanks for the info Michael but I disagree about scanning the dial. I
can find a local station on an old analog am tuner in 1 second. I just
whip the dial round and "hear". I didn't think am analog tuners even had
phase locks. Thanks again.

Analog tuned AM radios generally do not have phase lock loops. However, it
is interesting you use the word 'local' as spinning the dial would be harder
to find wealer stations as AGC effects would hide a weaker signal.


My point is that the muting on digitally tuned receivers is there for a
purpose. You can get rid of the mute feature in some cases by modifying
it, but you still get some effect because the receiver has to lock up to
the new frequeny. Most people don't hear what it sounds like becaus the
muting is there.

You're argument seems to be that you want a receiver to always be tuning
what it's tuned to, which means only an analog receiver (or some digitally
tuned receiver with a lot of effort spent on fast lockup) will provide.

There are lots of receivers that don't mute as they are tuned. Finding one
under $100 may be a challenge.



I'd much rather have the ability to get back to the same frequency without
any fussing, so digital tuning doesn't bother me.

WHen I had a Hammarlund SP-600 decades ago, I could spin the dial hard and
it would traverse most of the band. I couldn't hear what was going on, it
wsa too fast too. But in that case, it was simply that it all went by too
fast.

Michael

The SRII is top rated for sensitivity and to some degree selectivity. It is
highly rated for DXing. Of course, you need to have a working one, not one
that may be broken.

If you are looking for a radio where you can turn the tuning know without
muting, look at the Icon R-75 or Sony ICF-EX5MK2. Even the Grundig 750 has
minimal, if any muting while tuning the AM band.

If you are looking for something else in a radio, you haven't made that
clear, so it is hard for anyone to help you.

The following radios in this room don't mute:

Kenwood TS-850SAT
Japan Radio NRD-525
Kenwood R-1000
Yaesu FRG-7700

And the oldies..

Hammarlund HQ-100
Allied SX-190
Yaesu FRG-7

And a few others that have problems don't mute either.

Good old style analog radios, you can pick up stations between stronger stations. Nowadays though with all those new fangled electronic gadgets that create ''hash'', it is harder to pick up the weaker stations.

And you can do exactly the same thing with any of the radios above.
Analog or digital, it doesn't matter.

You're talking out your ass, as usual.

I own a G.E. (first version) Super radio, it works OK. I also own a Panasonic model RF 2200 radio, AM/FM/Shortwave Radio, it has both digital numbers/frequency read thingy and analog tuning, knob on it. One of the over three hundred radios I own is a shirt pocket size AM transistor radio made in the Philipines. It is amazing, simply Amazing how Good it is for DXing AM radio stations. Google,,, Panasonic AM FM Shortwave Radios
