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 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. -- BDK: Head Government Shill, Psychotronic World Dominator. Master of Remote Viewing.

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. |

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.
