Thread: Need an AM radio with excellent reception

  1. #1

    Default Need an AM radio with excellent reception

    I know there are several older threads related to this, but none of them have solved my problem.

    I am in need of an AM radio that has excellent reception. I currently have the 350DL, but that does not seem to be enough for my needs. I have also tried the GE Super Radio II, but that did not work either. I looked into some radios under $150, and found the Sangean PR-D5 and PR-D7, which are supposed to have excellent AM reception. Does anyone know how they stack up compared to the 350DL? Or do you know of any other radio which would offer reception better than the 350DL under $150, if that is even possible? Or do you know of any good external AM antenna's that are of any use?

    And can anyone tell me how Grundig/Sangean/Kaito compare when it comes to quality/reliability?

    Thank you for any help or ideas you can give me.

    In another thread, member StarHalo recommended the "Sangean DT-400: http://universal-radio.com/catalog/spcialty/4400.html, which has a tuner that rivals many car stereos.. "

    Well, you tried the best two currently produced portables. I'd say that if you are not getting the Dx results you want, that your location is a problem or you have Elec interference. Outside of that, the quick fix is a loop antannae like below:

    http://www.google.com/products/catal...CA0Q8wIwATgA#p


    If that does not cut it, go to vintage radios. The ones with the tuneable, huge, ferrite rod inside of them.

    If you like to experiment, contact an auto junkyard or vintage car sales board and find an old Delco AM car radio from the late 1960s. Probably some of the best tuners out there.

    The DT-400 probably would not be able to edge out a 350DL, though the PR-D5 might be able to by a tiny margin. But for the leap in performance you're looking for, you'll need an antenna - CCrane's Twin Coil model is the bang-for-the-buck performer; $80 might sound like a lot, but it performs nearly on par with the ~$300 indoor antennas (and well above the ~$30 loop antennas). I've owned one for a few years now, and it's worth the money for that particular station that almost comes in audibly/regularly, or if you're interested in DXing and hearing what's really out there.

    As a ham I would suggest searching ameteur radio forums.I don't do AM myself but many of them specialize is AM comunications. Receiving AM is a cakewalk for them.

    Thanks for the advice, I will look into this antenna. I have tried one of the cheap loop antennas branded under Grundig. It failed to make much of a difference. Can this CCrane antenna be used passively as well as connected directly? While I can use either method on my 350DL, it would be nice to use the antenna on other radios if I am going to make the investment.

    I have some older small tube-radios I have had restored, though they don't have a ferrite antenna. They have the traditional long wire in the oval shape attached to the back of the unit.


    Thank you everyone who has responded. Your help is very appreciated.

    Yes, and each method has it's own unique advantage; using it directly, you're essentially "turning off" your radio's internal antenna, and the CCrane now becomes your receiving element; this is fantastic since the Twin Coil is modular and connected by long cables, as you can set the CC someplace far away from the radio, even outdoors, and completely eliminate sources of noise near the radio. Using this method, I can set a laptop computer right next to my radio, and there's no interference to speak of.

    Using it passively, by setting the CC's ferrite stick atop your radio, you get maximum gain - both the CC and your radio's antenna work together for serious DXing.

    I frequently use the CC for a radio station I like to listen to up on San Francisco; it's 350 miles away and slowly fades in and out of silence about once every ten minutes. With the CC, it only fades once or twice an hour.

    Sounds like it will work well for my DXing needs. How well does it work for picking up more local stations?

    For example there is a station during the day that I can pick up during the day with my 350DL, but there is significant static since I am beyond the fringe coverage area. The station is a small station with I believe a 250 watt transmitter. I would like to be able to tune it in more clearly.

    There is also a station with the transmitter about 15 miles away. During the day I can tune it in on any radio, but at night they turn their power down extremely low, so I can only get it weakly at night with significant interference. I would like to cut down the static and fading. Would this antenna work well with either of these cases, or is it mainly designed for DXing the clear channels?

    I've had excellent results with small transmitters and the CC - When I was just starting DXing, before I had an antenna, I could very rarely almost sort of hear a station on 530 AM, just occasionally make out that there was a voice. Once I tried it with the CC, it came in like a local channel; the voice was giving directions on parking zones and terminals - it was the LAX "Tune to 530 AM for information" transmitter, 70 miles away.

    The CC will help amplify the station's signal; it performs best on stations you can hear present but aren't strong enough to be reliably legible (as opposed to stations you can't hear at all, for which there is no guarantee. An antenna can't receive something that isn't there.)

    Before you spend more money, what have you done to improve the reception? Sometimes just moving a radio across the room or placing it high on a book shelf will decrease the interference if it's local. Have you tried rotating the radio to peak the signal and/or null the interference? Once you've peaked the signal try lifting each end of the radio while listening to the program. To listen to a talk station more than 50 miles away from me I sometimes need to have my SRIII on a 45 degree incline to null local interference on that frequency.

    It's only 15 miles away, you easily receive it during the day, and then at night you can't hear it because of interference? They might not be powering down, they might have to change from omnidirectional to directional or vice-versa. Most likely you're getting another station on the same frequency skipping in and causing interference. Rotating the radio to null and/or peak the signal is your best bet. A passive loop antenna might help, but then again it might not. I'd try rotation to null/peak reception.

    With all due respect to StarHalo, I've read mixed reviews of the antenna he's suggesting. Most of the time a passive loop antenna like a Select-A-Tenna, Terk AM Advantage, or the Grundig sold at Rat Shack will work just as well. The main advantage of the C Crane antenna is that you can place it in a window or somewhere away from local interference and run a cable to your radio. That's not worth the $50 extra money to me. Select-A-Tenna also makes a model that you can place away from your radio, usually sells for less money, and doesn't need batteries.

    There are also plans on the internet to bulid your own passive loop antenna that you can do for next to nothing. All you need is some wire, something to wrap it around, and a variable capacitor you can salvage from an old AM radio.

    Thanks for the advice, but I have tried everything I can to get better reception. I have tried numerous radios, and none have gotten very good reception. I have rotated the radios and moved them around. There is not very much interference in my house, or around my house. My SRII, and S350DL both get reception that close to the Westinghouse, but none of my radios get the reception I am hoping to receive.

    It is possible that they change the direction they are broadcasting, but I know they power down as well. They drop from 1000 daytime watts down to below 150 watts at night. I tried the Grundig loop antenna, and it did not help much at all.

    I have looked into the antenna he suggested, and it looks like one of the best solutions I have. Even if it does not work as well as I would like, it should help my old Philco, which is not able to be moved around, and therefore currently has poor reception.

    However, I understand what you are saying, which is why I am at this point still researching my options. I am open to all ideas, and thank you for all the ideas you have suggested.

    Here's an antenna that has always interested me, but because of my luck with passive loop antennas I've never spent the money to try it out:

    http://www.ramseyelectronics.com/cgi...tion&key=SM100

    It's tough to beat a good tube radio on AM. That's why GE and Conrad Juston decided to make the P780 which is often called GE's first Superadio. Maybe consider an upgrade to an R-390A? I know a broadcast engineer on the left coast who considers them the ultimate AM BCB DX radio. He uses an inverted L antenna with his, but then he's got the real estate for a +200' antenna.

    Interestingly, his back-up receiver is a Kenwood TS-440SAT. Triple conversion, selectable filters, and great sensitivity once the built in attenuation is bypassed. I was pleased to learn this as my primary receiver is a Kenwood TS-450SAT.

    Passive loop antennas of that size really won't help much with a Superadio or radios close in performance, but they do amazing things with less sensitive radios. Although I've used them successfully to block strong stations on adjacent frequencies with a Superadio.

    Larger passive loop antennas will help. If you like to build stuff look around for plans to build a 2'x2' passive loop, and I think you'll be pleased with the results. I can't guarantee it'll help with the station you're chasing, but it should make a big difference even with a Superadio.

    Also, it's not a bad idea to get your Superadio aligned. Although it seems to be less of a problem with the Superadio II, it can't hurt. I touched up my Superadio III and it made a big difference. The selectivity modification I made to it also helped to make it more sensitive and more selective than my Superadio II or any of my Superadio boomboxes. I also managed to get the dial to track a lot better. It's still off on the higher end of the dial, but it's much better than stock.

    From that review:

    "I do own two radios which don’t improve noticeably with the Twin Coil, a GE SR II and a Panasonic RF-2200. (Note that it DOES improve my GE SR III). It would appear that these radios’s extreme sensitivity is the reason, but I am only guessing."

    I've read that other places as well. With a sensitive and selective radio the Twin Coil Antenna doesn't do much. It's utility then is mostly for lesser radios or for people who need a remote antenna because of local noise interference.

    To me this suggests that the antenna only performs similarly to small passive loop antennas, because I get similar performance with them. I can then assume that larger passive loop antennas would have superior performance.

    As of right now, I have decided to not make the purchase. Specifically because I want to see what happens with the radio royalty battle. The local stations I am hoping to get, do not stand a chance if they have to pay a royalty Therefore the antenna would not benefit me if the radio stations disappear.

    But thanks for the help, and I may purchase it in the future.

    That antenna looks like a good antenna, I hope someone reviews it because it looks worthwhile.

    I agree, it is hard to beat good old tube radios. The sound is excellent on tube radios.

    Surprisingly, I found that my superadio is the original superadio, not the second version like I thought it was. I had not used it much until recently, although I still think that the reception is better on the 350DL or even my old Realistic DX-60. I will have to build a passive loop antenna once I get the spare time, to see if it makes much of a difference.

    Do you know if Terk makes large loop antennas?

    As I said earlier, I have decided not to buy any AM antennas until I see what happens with the royalty battle. However, I will consider making my own in the mean time. Thank you everyone for all your help.

    Now I just need to figure out how to improve my FM reception significantly. I have been wanting to tune in a station (100kw 96.9) that is a little over 100 miles away, and I can rarely manage to tune in. Whenever I do manage to tune it in, usually another station (97.3) overpowers it, and it is actually about the same distance away, although it has a slightly more powerful transmitter. Any idea on how I am significantly improve my reception? I can't get 96.9 at all with my 350DL, only with radios such as my old Yorx, and I can rarely tune it in on that.

    Unfortunately no. Their passive loop is about the size of the Grundig. The only larger loop antennas I know of were made out of wood by a shop in the Baltimore area. They looked like a slightly larger and wooden Select-A-Tenna. Probably not large enough to make a noticeable difference.

    If you have a rooftop TV antenna then you already have your answer. Just point it in that direction and connect the radio to the coax via a TV balun. If not, you may want to consider getting an FM directional antenna from Rat Shack. Put it on the roof or in your attic and point it in the right direction. While both TV and Rat Shack's directional FM antenna are only log periodic in design, they do offer some gain and should help. If you want more gain then look around the internet for some simple yagi antenna designs.

    The big name in big loops is Wellbrook, but the price tag is big too. Their home page shows a pro tower installation of one of their 1-meter (diameter) loops: http://www.wellbrook.uk.com/

    Looking around the internet I found a kit that makes an 18"x18" passive loop which according to the review is better than the Terk or Select-A-Tenna:

    http://www.mtmscientific.com/loop.html

    Review:

    http://www.radiointel.com/review-amloop.htm

    The kit is pricey at $79, but they sell the plans, a template, and the hard to find capacitor for $25 which isn't bad, and then you can choose the materials yourself.

    This is a little more money than you mentioned but you might want to try a Internet radio if you have a high speed connection. As long as the station has a streaming broadcast you can listen. You can even listen to broadcasts from around the country - even other countries as well. Here's a link to one I've been looking at on Amazon.

    I apologize that I have not come back for so long, I have been rather busy. You have all been very helpful.

    I have not yet bought the C-Crane antenna. Do you know if the C-Crane is capable of helping old tube-radios? None of them have ferrite rods. My table-top Westinghouse has the inch-wide coil of wire on the back of the case. My Philco is capable of connecting an antenna directly, the Westinghouse is not. Both radios suffer from poor reception. They both have good sound, with the Philco having unparalleled sound on AM.

    I am still considering the C-Crane for my S350DL, but if I could use it on tube-radios, that would give me another reason to buy it.

    As far as expanding FM reception, which I mentioned a long time ago, I can not connect a rooftop antenna, so I am stuck with little antennas, amplifiers, etc.

    Agreed, but for casual listening on a station that wouldn't be challenging anyway, it's a handy convenience. I still DX with my radios..

    Yes, I don't own any tube units, but one of the reviews of the CCrane used it on an older tube Zenith Trans-oceanic, which helped it greatly.

    They still have some method of receiving a signal, which can receive the amplified signal from the Twin Coil. Again, connect directly to minimize interference, connect by loop for maximum gain.

    The CCrane will help your tube radios more than it will the S350, as the Grundig/Eton already has a large 8" ferrite antenna.

    I don't have a lot of experience with FM DXing, but the old-school wisdom is that the best indoor FM antenna is a whip mounted vertically inside a windowsill; CCrane sells a whip under the name "Fanfare", but it costs more than the Twin Coil..

    From time to time, I still do some AM Dxing.
    The best radio for the purpose proved to be the ETON and the SONY; both uses the CXA1238 chip, which is excellent for the purpose.
    There is a mod for the S350 DL which improves the IF stage, by replacing the two ceramic IF filters; check here for the mod kit:

    http://www.kiwa.us/GrundigS350.html

    It makes the S350 DL a real performer, you will not regret of the upgrade.

    I have found the Sony ICF-SW11 to provide acceptable performance for DXing, but you need to find a way to couple an external antenna.

    Six month ago I bought a Eton G3 which has a AM syncronous detector; since then I retired the Eton 350DL and the K-PO.

    The synchronous detector doesn't get enough credit or attention; any radio that has one of these will receive many more AM/SW stations that one without it. Stations that are physically impossible to receive become plainly audible just by flipping the sync switch.

    After I got my Sony 7600GR (which has a sync), I'm not interested in a radio that doesn't have the feature..

    How do the radios with a synchronous detector, specifically the Grundig G3 and Sony 7600Gr, stack up against the S350DL?

    The S350DL relies on its large 8" ferrite antenna alone to pull a signal, so a weak signal by itself on the dial, with no other stations infringing on it, will come in a bit more strongly on the S350. The catch is if the weak station is being drowned out by a strong signal - say you're trying to tune a distant station on 870AM, but there's a local station on 880AM completely mowing down the weaker signal, you can kind-of sort-of hear it weakly in the background, but it's not legible. If you can't null out the stronger station by rotating your antenna/radio, then there's nothing the S350 can do in this situation, you will never be able to receive the weaker signal.

    The 7600GR and G3 have modestly smaller antennas, so an in-the-open weak station won't come in quite as strongly as on the S350. However when you have the drowned-out signal problem, it's just a matter of turning on the synchronous detector - it's essentially a signal blocker that closes off any signals above or below the specific frequency you're trying to tune; so with the 870/880AM problem, you just turn on the Sync, set it for Lower Sideband (you want to hear the lower frequency and block what is coming in above it on the dial), and presto, the strong signal on 880AM completely vanishes. The weak station that was previously in the background suddenly sounds as though it's completely on its own on the dial, right out in the open. It works on AM and SW, and every time you "pull out" a station using sync, that's one more station you would have never gotten on a radio without the feature.

    As for the G3 vs 7600GR, I really like the G3's feature set, but it has had some quality control problems, and isn't as solid or powerful a unit as the radio it replaced, the G5. The 7600GR is a classic, and despite entering its ninth year of production, Sony still has no plans on changing it. The Sony is my recommendation for the ~$150 price range.

    A passive loop antenna will usually help with this situation by rotating to null the interfering station while peaking the desired station's signal. If both signals are in the same direction or exactly opposite each other from your position then you can't null, but you can still peak the desired signal. If you like to tinker you can make your own passive loop using varying gauges of wire which will limit the signal and audio bandwidth as the wire gets thinner.

    Wow! You love synchronous detection! Have you ever manually selected the opposite sideband? That's pretty much what synchronous detection does automagially, and you can do it with any radio that receives sideband as long as it doesn't use a BFO.

    I'd hesitate to call synchronous detection a signal blocker because what it's doing is using the radio's sideband filter to slice the RF for best reception. It's less blocking and more filtering - like I do with my communications transceiver. I select the opposite sideband and the filter options for best reception.

    The 7600GR uses a BFO.

    I knew even as I was typing that simplified layman's definition that one of the technical folk would jump on it..

    The OP mentions that he owns a "GE Super Radio II." Wow. I'd find a ham to align it and try again. Cool rig.

    OK, here's the counterintuitive part -- that's where some flame me for being a jerk (not totally uncalled for) and where some scratch their heads and thank me.

    All of the antenna suggestions are fine except that they all share one problem -- adding an external antenna to most (if not all) of the radios mentioned does nothing to supress the noise coming into them from their original antennas. This is important because about 98% of what a good antenna does for MW DXing is blank out interference with deep nulls. In my experience when you hook up a fancy antenna to any MW radio with another antenna attached to it it doesn't matter how deep the nulls are in the new antenna if you're still picking up the noise from the original antenna....duh.

    If you want to go with a great aftermarket antenna like a Kiwa Pocket Loop or the Ramsey SM-100 kit it's a bust to hook them up to radios that already have antennas that cannot be disconnected. Remember a good medium wave (AM) antenna actually picks up less, not more.

    To set up a MW DX rig around a custom antenna you must first find a sensitive AM radio that has no antenna. Having gone through this myself decades ago I can save you some trouble. Buy a lab quality 12V dc power supply. Then buy a lower mid-range priced car radio. Car radios rock for MW DX because they are sensitive and yet very resistant to the electrical interference always present in mobile environs. It is also key that they have no antenna. Aside from their sensitive performance and their robust build quality, the fact that they have no antenna is a MW DXers dream come true.

    With that gear you will be able to kick ass with whatever bleeding edge add-on MW antenna you can afford and the deep nulls you paid for in those snazzi new antennas won't have noise injected into the system as it would be if they were attached to any radio that still had it's own antenna.

    The key here is to go away from this discussion remembering that a top quality add on MW antenna is valuable not because it picks up more but because it picks up less and you'll likely hose the whole effect by hooking up that pricey antenna to any rig that has it's own inferior antenna still permanantly attached.
