Default SW Radio question

Hi ppl,

I am new to radio hamming although I have some experience
with electronics and I work in computing so I'm not afraid of
technical stuff Basically I am looking at buying a radio that
can recieve short wave and possibly setting up some sort of
aerial for it (have access to the roof where I live and I have friends
tha can help put something reasonably simple up there). The main
reason I'm doing it is to recieve Voice of Korea ( DPRK - North
Korea), I'm also interested in recieving signal from Moscow
I know they have a very powerful transmitter there so it shouldn't
be a problem but I've heard that the DPRK signal is weak. The
problem I have is mainly what sort of radio I should get
that would give me the best reception. I can maybe afford
to shell-out about a hundred pounds, maybe a bit more if I'm
really convinced. What would you recommend to a beginning radio
ham who would like a reasonably decent radio set and trying
to recieve signals from Korea ? Has anyone experience with
recieving Voice of Korea from England, or Western Europe ?
(Until recently VOK was called Radio Pyongyang)

Regards from
laura

Just consider the advice from the shortwave old timers in this room.I am
sure they will be more than happy to help you.I am not a shortwave
expert,I suppose I can be considered a casual listerner of shortwave
radio.

Have a look around this site:

http://www2.rnw.nl/rnw/en/features/m..._choosing.html

http://www2.rnw.nl/rnw/en/features/m.../rx_sort1.html

If you can stretch to 115 quid then the Sangean ATS 909 is probably the best
value decent receiver if you can get one.

http://www2.rnw.nl/rnw/en/features/m...rs/ats909.html

There are loads on ebay from a German dealer brand new at the buy it now
price of 115 UKP.

Dear Ms. Laura,

May I recommend a Sony ICF-SW7600GR, which I regard as the finest of
all small portable short wave radios currently available new? Along
with that receiver I should recommend you purchase a Sony AN-LP1 Active
Loop Antenna, which is a perfect (indoor, window-mount) match for the
radio.

Alone among small, relatively inexpensive short wave radios, it feature
a synchronous selectable-sideband circuit (which sounds complicated but
actually is not) which allows for superb reception of somewhat
difficult signals. It can eliminate adjacent-channel interference and
also eliminate selective-fading distortion (where an announcer sounds
as though he/she has a very bad cold which renders them
unintelligible).

I live in the USA but with the Sony combination I have received North
Korea and the VOR (which is one of my favorite stations; I particularly
enjoy their show "Musical Tales" which features fine Russian classical
music; I also like their "Jazz Show").

I hope you will consider the above as it affords you a superb
receiver/antenna combination which you will never "outgrow" even if
eventually you buy a table-model short wave receiver. (It is a great
combination to take on a vacation.)

Should you wish to erect an outdoor antenna, you can attach it to the
Sony without fear of "overloading" as long as the antenna is not too
"elaborate." In high-signal-strength Europe, however, the need for an
outdoor antenna is not critical, at least at first.

Your own experience will tell you, after a while, whether you wish for
something "better" or if what you already have is satisfactory.

I own quite a number of receivers (these things do tend to accumulate)
but, even though my table-models are "better" radios and have "better"
antennas, I use my Sony ICF-7600GR (I have three of them as well as two
of its predecessor model the '7600G) every day. (I use NiMH
rechargeable batteries in the radio and the antenna; this allows
running costs to be very low in the long run.)

Should you decide to buy my recommended combination, look into buying
from a US-based company as the pound-dollar ratio is so favorable to
you. Even with shipping it might cost you less than buying in the UK.
Of course, check with your local shops as well to compare their prices.
Two US companies I can recommend are Universal Radio and AES. Both can
be found on the web, though Sony prohibits web purchases (I have
absolutely no idea why!).

Should you like what you see, you can e-mail those US-based companies
for more information about purchase.

I wish you all the very best of luck.

Hi again,

Thankyou everyone for your advice it has been most helpful

I think I am going to go for the Sony SW7600GR ; a few people have
recommended it to me now and I have spent some amount of time reading-up
on it and it sounds very good. What is more the actually hearing
tales of people receiving VOK on it who are about the same distance
away from Korea is just exactly what I want to hear before shelling-out
cash becasue this is the primary reason I want an SW Radio.

I have a slight worry that if I leave the radio to come on at a
certain time (I'm trying to automate recording a program) with
the aerial plugged in that the batteries in the aerial will run
out .... I don't know, I haven't read enough about it all to
understand but I'm a bit confused because it says the AN-LP1
draws power from the radio itself via the mini-jack but on the
other hand it has batteries inside the aerial too - I don't
understand that at all %/

Anyway now I'm trying to find a shop, hopefully local, where I
can obtain it because I can't get deliveries to my home (a real
pain !! ). Maybe I'll be lucky and get it by the weekend, if/when
I do I'll post again and tell u how it went

Check around in the stores over there and see if they sell some sort of
adapters thingys you can use for your shortwave radio so you won't have
to be buying batteries all the time.By the way,I know a married Irish
woman whom is married to an Irish guy (she is from Caherconlish,Ireland
[near Limerick] and he is from Fethard,Ireland www.fethard.com
Caherconlish doesn't have a website,,, yet,according to her,Maggie) and
she works in the social services department at West Sussex County
Council in Bognor Regis,England.I have known them via the internet for
over five years.

Dear Ms. Laura,

Universal Radio sells an AC adapter for the Sony ICF-SW7600GR which
they claim is satisfactory. Sony's adapter is of the new "switching"
kind which, though much more efficient than the older linear adapters,
introduces a lot of noise; this makes it unsuitable for SW reception.

In any case, the adapters sold here are for 110V, not 220. I do not
know anything about the AC adapters sold in England. You must make sure
that any AC adapter you purchase for the radio is a linear one as
opposed to a "switching" adapter.

I don't recommend the AC adapter because, even if it injects just a
small amount of noise, this may impact your reception of Korea. (You
should check on that with people who live in the UK; Korea's signal
strength may be well stronger in the UK than the US.)

Of course, if you wish to use a timer to turn on the radio, then, of
course, you will need an AC adapter which would plug into the timer.

However, if you use rechargeable NiMH batteries (which is what I
strongly recommend for both the radio and the antenna), these can be
charged at any time (they have little or no "memory effect" like NiCad
batteries) so you could charge them every day if you wished. There are
chargers which will recharge those batteries in one hour or less.

The radio runs a very long time on rechargeable NiMH batteries and the
antenna lasts even longer on those batteries. You need have no fear of
the batteries going flat if you maintain them properly in accordance
with your listening habits.

The myth that "the radio powers the antenna" began, I'm afraid, with an
error in PASSPORT TO WORLD BAND RADIO which is maintained even in its
latest edition. It may be an error in interpretation. The radio will
power on (and off) the antenna (in other words, when using the antenna
with the '7600, one does not need to use the power switch on the
antenna; it is turned on or off with the radio), but batteries are
required in the antenna. It will not work if there are no batteries
installed. PASSPORT's terminology is unfortunate and has led to a great
deal of confusion.

The antenna has no input for an AC adapter, but, as it turns on and off
with the radio, there would be no problem with leaving the antenna
powered unnecessarily. (The Sony AN-LP1 has the "automatic" operation
only with the '7600 radio. It, of course, works with other SW radios,
but the power switch must be turned on and off manually. Note also that
the AN-LP1 is strictly for SW. It must be physically disconnected from
the radio when listening to MW or LW.)

I hope the above is of some use to you and, again, I wish you the very
best of luck.

Hi Joe,

I was an impatient child in the end and went and bought a Roberts R861.
They actually retail for quite a bit more than the Sony but I'm not
sure I did the right thing :O Its difficult for me because I can't
get deliveries where I live so I checked the local stores and to my
surprise the local electronics shop he had a Roberts R861 (2nd hand but
VGC) and was only asking £120 for everything including mains adapter.
I'm happy because the Sony was going to cost more than that and
the Xmas squeeze is on - I think I'm going to get so much into this
I will end up getting the Sony soon AS WELL anyway First thing we realised
is reception is rubbish here (right next door to a huge apartment block
and lots of buildings on all sides we think are blocking the signals)

The funny thing is that having the mains adapter plugged in seesm to
improve the signal rather than degrade it (maybe it uses it as an aerial?)
I understand that the telescopic aerial is for FM ? I plugged in the 'whip'
(long wire thing) and put it as high as I could (not very much!) but
we think it will be much better if we put an aerial up on the roof.
Should I just put a long length of wire up there ? Is it alright to
just dangle that down the side of the house to connect it or do we
need to use a special shielded cable to do that? I want to have the
computer running at the same time and it seems to interfer, maybe
it would interfer with the aerial lead coming in ? (I don't know
being inexperienced but that is what my hunch is...)

Anyway I have been glued to the thing all night and wonder if I'll ever
get to bed :-)) My first exciting discovery (I have been scanning and
writing down the channels or a description) was "All Indian Radio"
on 7.409Mhz. Also I think I got something from Nigeria on 7.382Mhz.
I couldn't get Voice of Korea at all, not one iota. Do you think the
Sony would fend better at that? Or is it just my aerial I need to set-up?
What frequency did you get VOK on?

Thanxs again, your post was very informative

Hi Laura.

You got a good radio in the 861. It's the same as the Sangean ATS-505
Good sound from the speaker, very sensitive off the whip, and acceptable SSB.
You'll hear plenty with it.

I'd be interested in knowing what Longwave stations you can hear. I'm pretty
sure there are still some LW broadcast stations in Europe.
