Does anyone have a recomendation for a quality AM receiver? I have a
cabin in the low Sierras and have trouble receiving AM. I would prefer
one that would not require an outside antenna.

I live in a rural area, but it sounds like your cabin is even more
rural. No matter what kind of radio you get, you will not get many
stations without an outdoor antenna. The good news, for AM, all you
really need is a piece of wire strung outside. 20 or more feet of wire
between a few sturdy trees works fine, then run it into the house by
drilling a 1/4" hole and caulk around it once it's inside. Pretty much
any sort of wire will work outdoors, insulated or bare. Use some
insulators on the ends. I'd use insulated wire coming in thru the wall.

If your AM radio has no antenna connector, but has a telescoping
antenna, just coil the wire around the telescoping ant numerous times. I
do this in my barns, because they are metal buildings. Without the
outdoor wire, I'd get no stations. That wire works for FM too, but not
quite as good.

If you use trees, be sure to leave some slack in the wire. Trees sway in
winds, and if the wire is tight, it may break.

**Assuming you have no internet capability (the best way to receive AM),
then your next best option is to find an old, 1960s vintage, solid

AM qualities were excellent. If you have lots of cash, then one of these
will provide superb AM performance:

I had one on the bench last year. Surprisingly impressive and quite

I agree with the vintage part Trevor, but I'd go with a typical house radio.. I have a bunch of early 60s AM transistor radios and many of them feature an RF amplifier. An Emerson 911 for instance picks up as good as any radio I've ever had, and they're pretty cheap if you catch one just right.

Also, a Select-A-Tenna supposedly works wonders for DXing although I've never tried one:

Hello, and you want a radio of requisite sensitivity so you can enjoy
the "quality' of AM radio? Can you parse languages other than English?
Just kidding. In addition to the advice already provided by others, you
might want to check with a seller like C.C. Crane. I assumed by "AM"
you meant the medium wave (535-1700 kHz) band. A multi-band
"communications" type receiver (with an RF gain control) might be a
solution but likely isn't the least expensive one if bought new. In any
event, reception using a simple, old-fashioned long wire antenna will
most often provide better performance than a built-in telescoping whip
antenna. Another possibility is to use a passive (no batteries
required) variable capacitor tuned loop antenna. These can be built or
bought, can be used indoors, and I've seen them dramatically improve the
MW band performance of inexpensive transistor portables. The radio is
simply positioned at the base of the loop (radio's internal ferrite loop
becomes inductively coupled to the antenna so no wire connection to the
radio is required), the radio is tuned in the vicinity of the AM station
of interest, and the loop capacitor is adjusted for maximum signal.
Sometimes the radio needs to be slightly repositioned to optimize the
radio-to-loop coupling. And finally you can rotate the radio and tuned
loop together for the strongest reception. Please let us known what
works for you. And one last thing: Don't rule out the use of FM
(assuming you like whatever program content is being offered) as I've
seen situations where AM reception is lousy but FM works. Sincerely,

Mpffff... This is an easy one. If you are looking, primarily, for good reception over top-notch sound (mostly wasted on AM anyway), and this is to be a single-purpose device, look for something like a solid-state GE "Super Radio" or similar. They are fair-enough sounding and far better than average at AM DXing capabilities. Low in cost for very good results.

http://www.ebay.com/itm/VINTAGE-GE-S...AOSwbRJZvvX 8 I keep one of these at our summer house that is no slouch at all. The AM band is pretty busy, especially at night.

A step up from there would be a multi-band radio such as a Zenith TransOceanic. Of those, the ne-plus-ultra would be the RD7000Y - and why that one? All silicon, has the tunable weather band, and will give you some amusing shortwave capacity.

https://www.ebay.com/dsc/i.html?_sac...x_kw=&_in_kw=1 One of these has lived at my work desk for over 20 years.

Hard-Core would be a Communications Receiver, something in the Hallicrafters, Collins or National lines - which are a whole different can of worms, do want an outside antenna, and likely will contain tubes rather than transistors.

And, one of these will truly separate fly-poop from pepper. Give it an 80' longwire and you will be getting AM from Hawaii - or thereabouts.

The old Vega/Ocean radios are very cheap dx sets. Some mericans might not like their origins. But don't worry, they don't run Kaspersky.

I keep one of these as well - a small hand-held - and, yes, it does very well. Competitive, but not better than my Siemens RK747. They are not easy to find in good condition, nor do they wear well. I paid $2 + about 4 hours of very persnickety work fixing the battery compartment and re-securing the guts on mine. Pure blind luck that it worked at all - but it does, and well..

https://www.doctsf.com/grandlivre/fiche.php?ref=40940 (not mine).

But if we are going into Euro-Exotics, the very best consumer-grade DX radio I have in all bands is this one:

http://www.ebay.com/itm/Grundig-Sate...UAAOSwls5Y6-Vk

The second best is the Zenith RD7000Y (and the best for sound overall). Followed by the Grundig YB500.

http://www.ebay.com/itm/GRUNDIG-YATC...AOSwdKZZ2tb Y

Point being that the smaller radios have smaller sound - if that is a consideration.

Repeat: Communications Receivers are a whole different thing. If the OP wants to pull stations from the moon or Mars, that should definitely be a consideration.

Thanks all.

first depends what you mean by quality,
able to hear weak stations?
or high fidelity?

in either case, the big problem with AM is electrical interference which will sound like buzz noise usually.

if you are out in the woods, your own stuff will be the only source so you have a chance to control it

light dimmer, wall warts, fluorescent lights computers, all these are potential sources of electrical interference.

use a battery operated radio and turn off the electricity and you will be surprised what you can hear especially at night.

Quite a radio!

But as to the car radio, aren't they so good because of the metal body
of the car that surrounds them? A ground plain? Or is that only for
FM. I know for FM every car radio I had worked better than every table
radio except 1, but I didn't have a chance to compare AM

I had one on the bench last year. Surprisingly impressive and quite
sophisticated (even has a synchronised detector!) AM section. A bit much
for a cabin radio though.

OK - here is "the deal" about car radios. Keep a few things in mind:

a) Moving cars are noisy, very noisy. Noisier than any listening room in your house by a very large margin.
b) Cars, in general, are tiny as compared to about any room in your house other than, perhaps, the bathroom.
c) Cars move, by their very nature. So they are pretty much always in motion relative to the transmitter by both angle and distance.

So, car radio manufacturers worry very, very little about s/n ratios, stereo separation, muting capacity, stereo/mono switching or any of the niceties found on even a relatively simple home tuner. They DO focus on sensitivity and AFC, some even do AVC based on ambient noise within the car. And, the bandwidth of the typical car radio after filtering is pretty wretched in many cases.

Meaning: a car radio will *receive* acceptably (for a car) under conditions that would have a decent tuner on full mute - or if the mute is disabled, making so much noise as to be intolerable.

Of course, what with HD radio and the concurrent 'cliff effect' of HD listening, how this works is even more obvious.

I've used lengths of plastic twine at the ends as insulators. Effective, always to hand, easy, cheap.

who has a junked car, offer them a few bucks for the radio. I'd get the
antenna too. Then all you need is a 12V power supply. Those can easily
be found. In the 70's nearly everyone had one of them, so they could use
an auto CB radio in their house.

If your cabin has no electricity, any car battery can be used to power
this radio, as long as you can charge it. (Use your car to charge it, if
need be).

You can mount the car antenna on the roof, but you'll need an extension
cable for it. The cords on those car antennas have always been a special
cord, and I am not sure what to use to extend it. Maybe someone knows
this.....

However, a long wire outside is still superior for an antenna.

Right, the AM band, which, regarding radio, is an abbreviation for 'Amplitude Modulation' as opposed to FM (Frequency Modulation). Unless you confuse AM (Ante Meridian) here in this thread to mean morning-time only radio use.

**Almost ANY radio that has an FM section has a really crappy AM section
(excepting the Sansui I referenced earlier). Since the early 1970s,
manufacturers have pretty much ignored AM radios. There are exceptions,
of course, but they are very rare. Here in Australia, for instance, FM
transmissions did not begin until the mid 1970s. Hence, there was a
thriving business for manufacturers building high quality AM tuners. And
trust me: They were very good indeed. Back then, it was possible to
deliver sound quality that rivaled FM (mono) under ideal reception
conditions. In fact, I have such an AM tuner in my workshop. I never use
it, of course. For good AM, you need to find an AM only tuner that was
built before FM was really popular.

FWIW: The best AM radio I ever heard was my very own, valved, 4 stage
TRF, radio, which used an infinite impedance detector. The design was
taken from a long-departed New Zealand electronics magazine. I built it
as a teenager and the thing sounded glorious. So good, in fact, that I
called my local radio station to complain about their 'B' turntable,
because I could clearly hear that the stylus was worn/chipped. They
thought I was nuts, but swapped out the faulty stylus anyway.

Quite so, I had a Kenwood "system" with separate components.
The AM/FM tuner was absolute **** on AM.
Single IC "AM subsystem" both sensitivity and selectivity were marginal.

When I was "gifted" a Technics home entertainment system, I threw the
Kenwood in the trash where it belonged.

**Assuming you have no internet capability (the best way to receive AM),

I had one on the bench last year. Surprisingly impressive and quite
sophisticated (even has a synchronised detector!) AM section. A bit much
for a cabin radio though.

I was thinking about using a car radio too. But why limit yourself to
AM. Get an AM-FM. AM radios these days are mostly talk shows and
religious programming. You;ll get more music on FM. If you know someone
who has a junked car, offer them a few bucks for the radio. I'd get the
antenna too. Then all you need is a 12V power supply. Those can easily
be found. In the 70's nearly everyone had one of them, so they could use
an auto CB radio in their house.

If your cabin has no electricity, any car battery can be used to power
this radio, as long as you can charge it. (Use your car to charge it, if
need be).

You can mount the car antenna on the roof, but you'll need an extension
cable for it. The cords on those car antennas have always been a special
cord, and I am not sure what to use to extend it. Maybe someone knows
this.....

**Almost ANY radio that has an FM section has a really crappy AM section
(excepting the Sansui I referenced earlier). Since the early 1970s,
manufacturers have pretty much ignored AM radios. There are exceptions,
of course, but they are very rare. Here in Australia, for instance, FM
transmissions did not begin until the mid 1970s. Hence, there was a
thriving business for manufacturers building high quality AM tuners. And
trust me: They were very good indeed. Back then, it was possible to
deliver sound quality that rivaled FM (mono) under ideal reception
conditions. In fact, I have such an AM tuner in my workshop. I never use
it, of course. For good AM, you need to find an AM only tuner that was
built before FM was really popular.

FWIW: The best AM radio I ever heard was my very own, valved, 4 stage
TRF, radio, which used an infinite impedance detector. The design was
taken from a long-departed New Zealand electronics magazine. I built it
as a teenager and the thing sounded glorious. So good, in fact, that I
called my local radio station to complain about their 'B' turntable,
because I could clearly hear that the stylus was worn/chipped. They
thought I was nuts, but swapped out the faulty stylus anyway.


I can understand what you're saying, but to enjoy it, you first need
radio stations worth listening to. You may have it completely different
in Australia, but where I live, AM is just talk radio (mostly
politics), or religious stuff. For that, who needs quality sound?

I do have to compliment a local station though. For years there were
about a dozen FM stations that all played country music. (It seems that
when you live in a rural area, they think everyone listens to country
music). That station recently started an AM station that plays oldies
rock, pop, and some country too. All from the 50s thru the 90s. Thats
the first time I listened to AM in many years.

Since wer are talking AM radio. I recall back in the 90s or was it the
early 2000s, they were working on AM Stereo. What ever happened to that?
I have not heard anything about it in years.

Ok, now i have to ask..... What kind of music do the kangaroos prefer to
listen to in Australia?

They claim that cattle prefer country music in America, but when I was
working for a dairy farm, I changed the radio to a rock station and the
cows seemed happier..... (However, the owner of the farm was not real
pleased).

There is some music still and the government broadcaster (the ABC) keeps the signal pretty clean and wide band - up to 12kHz at most.

LOL! They must have hated getting phone calls like that. Is there a schematic anywhere on line for that circuit?

GE Super Radios, they're really good, but the one I have is not quite as sensitive as some of the vintage 8 transistor AM battery radios that I have squirreled away. The Emerson 911 I cited is basically an 8 transistor with a push pull output section. For a small radio it has decent tone. It has an RF amplifier and a separate oscillator and mixer. Since most people don't DX AM for music, it's clear and toney enough. They were also made in large enough numbers that they can be had fairly cheaply, but most vintage domestic radios of the time that were an honest 8 transistor design are very sensitive. Pretty much any leather cased Zenith, Motorola, Admiral and RCA radios of the early 60s are excellent performers, and the larger of them have really nice tone.

BTW, I remember repairing a 60s Japanese transistor radio that had the transistor count proudly printed on the front of the radio (either 6 or 8 - can't remember), but two of the transistors had a leg cut off and used as diodes. Technically they were transistors but sheesh.

Just a few things in general from questions asked:

a) GE Super Radios are very good general consumer radios with excellent AM and FM capacities.
b) I am a bit of a collector of radios, with one foot pretty deep into Audio as well. So, I have a large number of comparison points from the 1920s through the 1990s. Of all of those, the best AM reception I get (without an external antenna) is on my Zenith RD7000Y TransOceanic. With an external antenna, it would be the Hallicrafters SX16. The Halli is a beast in weight, takes an external speaker, lots-O-real estate and will heat a small room in the winter. It is also my only communications receiver - chosen because I tripped over it (no kidding) at a flea-market, the seller was an old friend, and the price was right.

Tied for second place: Grundig Satellit 700 and my B600L TransOceanic.

Tied for third place: The GE, YB500 and H500 TransOceanic.

All of the above are very good radios, all but the GE designed specifically with DXing in mind, and really with very little to choose between them. The GE is a happy accident of good design and good execution resulting in a pretty hot radio.

On the audio side, I own two component tuners with AM sections. The Soundcraftsmen T100 AM section is an unhappy joke. I can get the local torches reasonably well (KYW being one). But no real distance. On the other hand, the Dynaco AF6 is not half-bad for AM. I have never tried it with other than the ferrite antenna on board, but I suspect it may have hidden depths with a very good antenna. It also helped that I aligned it for AM when I got it. Being able to do AM and SW alignments is a side benefit of the hobby, but does give me a good base for judgment.

But, if an inexpensive, reasonably well sounding stand-alone portable radio is desired - the GE Super Radio is a fine option with not a half-bad FM section as well.

So true. And the politics are, fwiw, mostly conservative.

I do have to compliment a local station though. For years there were
about a dozen FM stations that all played country music. (It seems that

the first time I listened to AM in many years.

If someone has a shortage of radio but plenty of bytes, I recommend
RadioMaximus**. It has a free version that does everything the paid
version does except you can't schedule a recording in advance. You can
still record, but I wanted to record The Big Broadcast on WAMU on Sunday
nights when I wasn't here, so I bought it, maybe $40.

He has a list of hundreds of online stations from all over the world,
categorized by location, type of radio, talk, oldies, classical, and I'm
pretty sure you can find religious too.

It doesn't depend on a webbrowser, so when you open too many tabs in FF
and it freezes or crashes, it doesn't interfere with listening.

Then you can get wireless speakers for the rest of the house and even
outside. 20 years ago I got 2 1/2 pairs of RCA wireless for very
cheap, but now they are harder to get and they are pushing bluetooth,
which is more expensive and afaik, the range is less. I listen mostly
to talk and even when it's music, it doesn't have to be stereo, so I put
one speaker in my bedroom, one in the bathroom, one in the basement, the
kitchen, and there's a spare for outside though I never use that. But I
can have the same station no matter where I go. Both RCA and bluetooth
run on batteries too.

**He has a second product too, RadaralTuner or something like that. They
seem very similar, and the biggest problem with radiomax is that some
stations are not available all the time -- one oldies station .977 the
Oldies Channel** will play for 30 minutes or 2 hours and then stop, but
181FM Good Time Oldies will play for days in a row with no problem --
and I figure he provides the same list of stations to both programs (you
can add them yourself also) so changing programs won't affect that.

**They give some of them numbers although I think the numbers don't mean
anything.

These station urls are not widely available. I think volunteers have
collected the list for him, although last I looked, WYPR was not on his
list and when I went to its website and clicked Listen Live and got that
url and copied it to RadioMaximus, it didn't work. I wonder why. So
when I want that I listen on the radio. It's competitor 40 miles away,
WAMU, I can only get on car radios and my expensive table radio and
sometimes on a very cheap radio but that one seemed to break (not even
on some fancy tuner), but I listen to it on Radiomax for hours on end.
Listening to it now.

Yes, it was a competitive advantage for advertising purposes. And,
the manufacturers could use "bad" transistors for this - ones which
had failed the test for one reason or another, had an open emitter or
open collector, etc. They could get these cheaply, or use the bad
ones out of a large lot they'd bought in bulk.

Another thing about crappy AM is bandwidth. Normally it is narrow and will not reproduce the highs well. I guess they were going for selectivity and lower noise. With FM the frequency response remains but a narrow bandwidth IF will increase distortion. Some high end FM tuners had switchable bandwidth which allowed for the lower distortion (especially in stereo) when set to wide and better selectivity when set to narrow. I remember seeing an AM with that feature but for the life of me can't remember what make or model. I think it had shortwave.

If you want talk radio shortwave is the way to go, especially the forbidden band. I don't know exactly what frequencies are forbidden but all you have to do is look at the in the stores or read the specs, you will find frequency ranges missing. The politically incorrect go there, like American Dissident Voices. Those bands are omitted ostensibly because the programming is US based and intended for non-domestic audiences.

The same FCC are the ones that mandated tuners must have both AM and FM. This is one reason, people with separate tuners want high fidelity and are not concerned with AM.

girlfriend and we would snuggle (well, **** our brains out, actually) in
her parents lounge room, with the light off, listening to 2CH. 2CH was
this station that played 'easy listening' music. Nothing too serious,
but great to snuggle by. I have my bedside radio (a DAB+ one) tuned to
them. DAB+ is, for all intents, on a portable radio, as good as FM.

http://www.2ch.com.au/

Most of the other AM stations are occupied by right wing 'shock-jocks',
whose combined IQ doesn't reach room temperature.

I think they might still be talking about watch jewels if digital hadn't

It seems to me only the balance wheel (is that it?) and two or three
gears beyone it turn enough to need jewels. ????

BTW, both my and my friend's Philips DVDR with HDD have clocks that keep

wwhen I went away for 3 months, I had to record 1 minute after it should

have that too.

Not nearly as difficult, but somewhere I got a console record player
from the 30's or 40' and I removed the ~10" woofer and hte small speaker
(not sure what it takes to qualify as a tweeter) and mounted them on a
board in a corner of the bathroom ceiling. Got great sound, maybe partly
becuase of the tile walls. That was 1975. I've moved once and I'm
using it in the new place but the TV might have a week audio. Sound is
not loud enough. I have to change tvs.

I take showers in another bathroom and never take steamy baths, but
still after 42 years the tan burlap that I used as grill cloth has
discolored.

If you want talk radio shortwave is the way to go, especially the
forbidden band. I don't know exactly what frequencies are forbidden but
all you have to do is look at the in the stores or read the specs, you
will find frequency ranges missing. The politically incorrect go there,
like American Dissident Voices. Those bands are omitted ostensibly
because the programming is US based and intended for non-domestic
audiences.

The only "forbidden" frequencies (as far as radio receiption goes)
I've ever heard of, are the UHF frequencies used by the
older-generation (analog) cellular phone systems. The FCC prohibited
(and still prohibits) making general-purpose radio receivers that can
tune to them, reportedly due to influence from the cellphone companies
who could then claim that these phone systems were "secure".

As far as shortwave goes... I have never heard of the FCC, or anyone
in this country somehow "forbidding" radios from receiving any of
these frequencies. Just doing a quick look at multi-band receivers on
the market today (a quick web search), most of those which offer
shortwave at all have continuous coverage from below 2 MHz up to 22
MHz or more (many to 30 MHz which is the nominal end of the "high
frequency" radio range and hence where "short wave" is usually
considered to end).

Above 30 MHz, long-distance (e.g. international) signal transmission
is difficult and unpredictable... it depends a lot on the state of the
ionosphere, which depends on the solar cycle and time of day.

The same FCC are the ones that mandated tuners must have both AM and
FM.

Can you cite the regulation in which they actually mandated this?
I've never heard of it.

Ditto for the "forbidden frequencies" - where are the laws or
regulations which "forbid" them?

"where are the laws or
regulations which "forbid" them? "

Poor choice of words, there probably is no actual law or regulation, but for some reason manufacturers omit those frequencies.

There is something though because years ago the FCC was considering pulling a station's license because their programming "appeared to be intended for domestic audiences". Need I mention that the station was full of dissidents who were very critical of the US government ?

"Can you cite the regulation in which they actually mandated this?

The both AM and FM thing I remember distinctly due to my exposure to high fidelity. I'm pretty sure it was in the 1970s. A quick Google does not turn up anything on it though, but that is not uncommon. Much of this older stuff was simply never archived. Suffice it to say I didn't make it up. I didn't imagine it.

I wonder if I could at least get the date from archives of High Fidelity magazine, to which I subscribed for a time. They used Hirsch-Houck (sp) labs to test everything and though AM was no big deal they tested it anyway to see if the manufacturer was lying in the manual. Of course the consistently found poor performance, but then they didn't lie about it. The AM section was there, I bet some people never ever used it.

These old laws and regulations can be hard to find. We've heard about the crazy laws like against French kissing in public, that you can only beat your Wife on Sunday and all that, but that info is from specialty sites. To find them on an actual government site can be nerve wracking.
