I wonder what you would nominate as the best-ever receiver for the U.S. AM broadcast band (vintage or modern). If there's any sort of consensus on this, I'm going to try to buy one (or two <IMG SRC="http://antiqueradios.com/forums/smile.gif">. Thanks in advance for any comments.<P>Mr. Transistor <P>------------------<BR>

When I was a youngster in the early to middle Sixties I had a transistorized portable radio that was able to pick-up on many occasions a bilingual Mexican broadcast station in the lower portion of the AM radio dial just before the sun came up at my location near the eastern shore of Lake Erie.<P>I have long had a mild curiosity about the claims made by some of the performance of the GE Super Radio III...For those unfamiliar with it, here is a link to its description:<BR> <A HREF="http://www.universal-radio.com/catalog/spcialty/0547.html" TARGET=_blank>http://www.universal-radio.com/catalog/spcialty/0547.html</A> <P>Anyone have experience with this particular radio and willing to share their impressions, observations and experience?<P>Bruce<BR>WC5CW<P>------------------<BR>

I have two of the GE super radios. One in the garage and one in the shower. Great audio, but all I listen to is my SSTRAN transmitter. I have not found either of these radios to be anything but ordinary for long distance reception. <P>Just my thoughts... <P>BTW I paid 3 bucks each at thrift shops. <P>bob in phx. <P>------------------<BR>

Since we're supposed to be talking about communications receivers here, I'll nominate my National HRO-7.<P> <IMG SRC="http://antiqueradios.com/albums/national/HRO_7_1.jpg"> <P>While it has enough selectivity to separate closely spaced MW stations, it's IF is not so narrow that it distorts the audio like some other receivers do. I would vote for the Hammarlund SP-600 but it's audio output stage leaves something to be desired.<P>Dave<P>------------------<BR>

I agree with Bob in PHX. I've had a GESR3 for about 3 years now. Nothing special.<P>------------------<BR>Steve, KK7UV

My Sony ICF-7600D is my favorite "Traveller"...<BR>It's vintage is 1982,I believe, and other than a crappy FM band, the SW is great!<P>...Jim<P>------------------<BR>I try to take one day at a time....<BR>but lately several days have attacked me at once.

The best user reviews of short-wave radios were in annual issues of the World Radio TV Handbook. I believe they started publishing reviews in the mid-1980s. At one time or another they covered low-cost models, portables, serious hobbyist models, and sometimes professional ones. <P>------------------<BR>

For MW DX [my specialty!]:<P>Vintage:<P>Collins designed - multiple manufacturer - R-390A [I have a genuine Collins R-390A]<BR>Collins/Motorola R-390<BR>Collins designed multiple manufacturer R-392<BR>Hammarlund HQ-180 and HQ-180A [I have an HQ-180]<BR>Hammarlund HQ-129-X [I have an HQ-129-X][and the HQ-120, HQ-140, HQ-150] - these single conversion, 3 stages of IF Hammarlunds offer an awful lot of MW "firepower" at a good price, even sometimes on ebay.<P>Semi-modern:<P>Kenwood R-1000 [use an outboard preamp for MW or better yet, one of the Quantum antennas referred to below, as the R-1000 doesn't have the greatest MW sensitivity - otherwise it is good, with a noise blanker to dream about! I had one, but gave it to my brother for Christmas a few years back.<P>Yaesu FRG-7 - wonderful on MW - just remember to tweak the preselector. Loves Quantum antennas see below. May go snaky with a random wire if too near strong locals. Have one and it is a dandy DXpedition rig.<P>Modern:<P>Drake R8/R8A/R8B [ I have an R8]<BR>ICOM R-75 - especially with KIWA mods<BR>Ten Tec RX-321 - got one and LOVE it - [the RX-320 is pretty decent for a PC receiver, but it is the rare, custom RX-321 that is truly outstanding - mine is running right now]<BR>Palstar R-30 series - especially with optional Collins filters<P>Semi-Modern Portable:<P>Sony ICF-2010 - got one<P>Modern Transportable/Portatop:<P>Tecsun [manufacturer and part designer]/Drake [part designer/repairer][under the "Grundig" label - keep in mind the only thing Grundig about these is the name!] Satellite 800 - if you can get a good one, they are superb - but don't expect much from the tiny built in ferrite bar - needs an external antenna for MW. Refurbs can be a good bet, as a real refurb has been "fixed" by Drake. Be cautious about refurbs on ebay etc. Best purchased with return privilidges - you might have to return one or two before getting a good one. May need some "o rings" added to fix tuning knob - can get the o rings at you local plumbing store! Mine works well except for some quirks.<P>External loop antennas:<P>Quantum QX Pro - outstanding active loop antenna with 15 inch ferrite bar - works great with modern and old rigs alike - for the latter, order the custom impedance matcher box. Have one and love it.<P>Quantum QX - similar to above but with a 7.5 inch ferrite bar. Also very good. had one but sold it to trade up to the "pro".<P>There are others, but these rigs are great.<P>Really tight budget? Grundig/Eton/Tecsun S350 - once again, you will need return privelidges as Chines radios leave quality control to you the buyer. Lots of turkeys leave the factory and its your job as buyer to sort this out by returning until you get a good one. With the Chinese rigs, its not a case of the customer is king, rather, the customer is the QC dept! But, when they get it right, these Chinese contraptions can be good. I have two S350s, one at the office, one at home. Great grab and go portable for MW DX. SW not that great. FM is good in remote areas, but prone to "downtown overload", so to speak.<P>Phil Rafuse<BR>PEI Canada<P><P>------------------<BR>

Since I've been experimenting with home-brew loops and preselectors--both regenerative and multistage, on the AM BCB, I find the receiver itself much less critical than what's on the front end. <P> <IMG SRC="http://antiqueradios.com/albums/Misc/LoopAmp.sized.jpg"> <P>------------------<BR>OZ

OZ, et al...<P>I don't want to divert the discussion away from Mr. Transistor's original question, but insofar as Phil's posting caught my attention with regard to his mention of the Quantum loop antennas and now your posting with regard to your nicely (!) constructed homebrew loop, why not a new thread devoted to the subject of loops and their performance at MW, both commercial offerings and homebrew designs...It's a fascinating topic many of us could learn from...You could begin by a brief description of yours with regard to its circuit and construction details.<P>FWIW<P>Bruce<BR>WC5CW<P>------------------<BR>

I agree with Bruce. I would see the topic covered also, as I don't know much about them, other than the basic theory behind how they operate. But comparisons of different types, construction plans and such would make an interesting topic. However it probably should be in the Discussions forum rather than here.<BR>Curt<P>------------------<BR>Curt, N7AH<BR>(Connoisseur of the cold 807)<BR>QCWA# 25085 AMI# 242<BR>CW forever

For further discussion of loops, Go to the "Antique Radio Discussions" section "AM Loop Antenna". I put it up to the top of the list again. Great subject. Very interesting...<P>------------------<BR>OZ

Thanks to eveyone for these great posts. I've taken many notes. I'll continue to check the thread for additional comments. I certainly appreciate everyone's input!<P>Mr. Transistor<P>------------------<BR>

I'd have to nominate my Hammarlund SP-600 JX-17. Audio seems fine to me. Can you explain what audio problems the SS-600 has?<P>------------------<BR>

Back on your original subject, the military R-392 has to be right up there. With 2 TRF and 5 or 6 IF stages, plus triple conversion on BCB, it's hard to beat. The noise limiter on this set also works as well or better than any I've used.<BR>Feeding it with a hoola hoop loop has gotten me some great DX--in the basement!<P>------------------<BR>OZ

<P>I also have a JX-17. The audio output stage seems to have restricted bass. This may have been done on purpose to achieve better intelligibility. These sets were designed to drive a 600 ohm line. Even with the proper matching transformer set-up, it doesn't seem to have as much power output as the National.<P>The National, on the other hand, seems to have more power and a richer, more "robust" sound.<P>Dave<P>------------------<BR>

I use my Collins R-390A with the Quantum QX Pro with great results. The Collins is my personal MW favourite amoung my receivers for two reasons - first, it is a superb performer and second, because I spent many hours taking it from incomplete to working poorly to working really well. I learned an awful lot in the process. And, my Collins "asked" me to get an URM-25D for companionship and alignment. I love using the URM-25D!<P>My Hammarlund HQ-129-X also works very well with the Quantum. Strangely, my HQ-180 does not like it quite as well - but the "180" works gangbusters with a 70 foot wire and a ground isolation 10:1 balun, or more correctly, unun {I keep wanting to type onion LOL}. My 180 was modified quite a bit, and the antenna input modified quite a bit from the schematic, so that may be it.<P>As for this balun/unun, if anyone is interested, email me and I'll forward a link to his website. He sells them on ebay as buy-it-nows. I have bought several baluns/ununs and they are good - very good for MW & SW receive and QRP transmit. The prices seem reasonable too, although they have crept up. <P>Of course, its possible to make your own too! I have Jerry Sevick's book on baluns and I hope to become balun knowledgable someday <IMG SRC="http://antiqueradios.com/forums/smile.gif"><P>Phil Rafuse<BR>PEI Canada<P>------------------<BR>

The bass is not there on the SP-600. My JX-37 which is a 1960s military model doesn`t have it either.<BR>Bass was not a concern for reception.<P>------------------<BR>Rodney

What I did on my SP-600 is I replaced the audio coupling capacitors with higher values. <P>------------------<BR>
