I am feeling frustrated due to the lack of response to my
order of IBS's white paper.  I gave the answering machine
all info and even urged them once by talking to the machine.
But no response.  Does anybody know what is happening to them?

Subject:      BBC Callin

        Another subject which might be worth mentioning is the new  BBC
Worldwide or whatever it is they call it.  I have been listening to the
BBC since around 1960 (I think it was still called the General Overseas
Service then), and have during that time subscribed to London Calling.
I just received my latest copy of the new magazine in the mail along with
a notice saying that since I had not yet sent in my new subscription this
would be my last issue.  I promptly threw it and the magazine in the
garbage.

        Three copies have convinced me that if I want to read this sort of
magazine I can do so by buying an airline ticket.  That's the sort of
magazine it is.  Somebody decided to fill up a certain amount of pages
with articles, and so they went out to find articles to fill them up with.
Articles about programs on the World Service.  Articles with little or
no journalistic merit at all.  In short, articles of the sort dreamed up
by a second-rate public-relations man.  From what I hear, the BBC used to
have a fairly decent magazine called The Listener.  When I heard of the new
magazine, I thought it was going to be a World Service version of The Listener
(which, I believe was discontinued, along with Punch not deemed to be
sufficiently up-to-date).

        Many of us remember the think-tank that recommended that the World
Service in English and all other services other than those to Eastern
Europe be discontinued and that the BBC overseas sedrvices be turned into
something they thought was more useful:  an organ for a propaganda ministry.
Not too long ago an editorial in The Economist recommended shutting down the
BBC completely in line with the availability of satellite radio and television
(they did not even mention overseas broadcasting).  The government has just
cut World Service's budget again.  Now maybe they think that anybody who
can't afford $60 an hour for NewsNet or Dialog doesn't count, or maybe they
would just prefer the sort of news that the BBC broadcasts is better off not
heard, and maybe they think that cultural, scientific, and entertainment
programs are a useless frivolity.  If they do, let them just say so honestly,
like they did in Canada, Israel, and Norway.

I bought an ATS-800 for a gift, and tried it out a bit.  It seems about
as good as my old ATS-803a was (I've loaned it out so I couldn't test
it side-by-side) in open air.  However, when I brought it inside my
mobile home almost no signal came through (my 803a had an external
antenna jack that I hooked up to an external antenna).  I don't know
if an apartment without so much metal like my mobile home would
have problems or not.  And it worked great in my car.  Overall,
it seemed to be a good quality radio.

And Universal (800-431-3939 or 614-866-4267) sells it for $90 plus
$5 shipping (at least shipping to the states).  They also sometimes
have used or returned models in for a discount.  I was able to get my
gift radio for $79.95 since someone had previously returned it.  I
couldn't tell it from new.

    I've connected a longwire directly to my "50 Ohm" terminal and
    nothing noticeably good or bad has happened.  It's possible that
    using the 600 Ohm terminal may give you better reception, but it
    certainly is not obvious to me that it does.

    I have a Lowe HF150; your radio may be different.

    Again, this may depend on your radio.  I'm currently running a
    groundwire, but I'm not sure it makes a difference.  Running a
    true "ground wire" is complex, because the wire needs to be thick
    (like 6 guage), short, as straight as possible, and it needs to
    go to a good ground, which can be difficult to find around your
    apartment.

    IMHO, the best advice I've seen came with a record player I
    bought.  It said "Connect the ground wire.  If there is more
    hum or noise than with the groundwire plugged in, disconnect it.
    If there is less noise, leave it plugged in."  If it's the same,
    I guess I'd probably leave it there too.

- In mobile applications, I prefer digital frequency readout to analog
because I can "read" it faster.

- For home AM and FM listening and DXing, I prefer an analog dial with
a digital supplement.

- For general shortwave and VHF/UHF listening at home, I prefer a
digital readout although a supplemental analog dial is appreciated.

In any event, I prefer smooth, gear driven tuning over use of
a dial string, and analog dials should have linear graduations.

A large, weighted tuning knob of 2-1/2" or larger is preferable
in fixed station applications.  I appreciate adjustable torque, too.

UP/DOWN tuning pushbuttons not welcome.

This freq. is a Air Traffic Control frequency for a specific area in
Africa. I don't know the name exactly, but it is something like AFR-1.
It is used by several ATC-stations in Africa, also Nairobi and Khartoum.

The HF-freq's replaces the usual VHF-freq's, when the distances between
aircrafts and ATC-stations are to far, like the African continent or
the Atlantic Ocean.

Most of the time you hear position-reports from flights flying in that 
area. A position-report gives the actual point the flight is passing
and an expected time for the next points on the route:

	KLM563:		Nairobi, KLM563 position.
	Nairobi:	KLM563, go ahead.
	KLM563		563, reportingpoint-A at 11.45
			     reportingpoint-B at 12.30
			     reportingpoint-C next
			     FL370.	
	Nairobi:	<repeating the message>

The first point is the actual position with the time (in zulu-time), the
second is the next reportingpoint + the expected approach-time for this point
and the third is the next after the second.

Sometimes wheater-information is added to the position-report:

	KLM563		At 370, wind 070,blabla knots and tempature -51

You can also hear request's for changing the Flight Level:

	KLM563:		563 request to climb to FL (Flight Level) 390

On these freq's you can hear the flights to Somalia. I'm for 99 %
sure they use the call-sign "United Nations" with a number.

I tend to agree with Dennis Gibbs when he says that digital display radios
don't have a great feel to their tuning knobs.  I have used the KENWOOD R-2000
and the JRC NRD-525 extensively, and neither compares with the old tube sets.

I have to throw my two cents in for the Hammerlund SP-600 (in its various
incarnations).  It has THE smooooothest tuning feel of any radio I have used.
(I also have an R388 and an R390A)  Dennis Gibbs also says that the R390A
knobs are hard to turn; by this I assume he means the Megacycle
change knob is hard to turn.  There is no reason why the Kilocycle change knob
should be anything but smooth.  If the latter is difficult to turn, it probably
indicates mechanical alignment and/or uneven torque of one or more sub-
assemblies.  I will grant that the R390A Kilocycle change knob will never be
as smooth as the SP-600's, but it should not be "hard" to turn.

Another tube set that has very smooth tuning is the AR-88/CR91-A.  It is an old
WWII set which also has fantastic audio quality, which makes for genuinely
enjoyable program listening.

     There's been quite a lot said about EEB; most of it not very nice. I live
nearby, and have never had any of the experiences that others have mentioned.
The staff has always been courteous, and very knowledgeable, without sounding
snobby at all; even to my most basic questions. I purchased my R8 from them
and love it. I don't usually spend that kind of money, so I spent literally
hours in their demo room, playing around. I even brought in my own
computer equipment and cables to play around with interfacing. All they
ever said to me was something like, "just don't blow it up." In sum, they're
knowledgeable and friendly and willing to spend as much time with you as
you need.
     Someone recently mentioned something about them being "rich"
hams. For the record, if they're rich, it's not from working there, since
most of them work for FREE; they feel like it's a civic duty to the radio
community. The benefit they get is that they can buy equipment for themselves
at wholesale prices.
     Everyone should be lucky enough to have an EEB nearby. Where else can
you look at so much equipment in one place, and talk to people who know what
they're doing? Let's stop the lynch-mob.

Well yes, no, and maybe. You can slope detect FM if you use very loose
coupling so that there's enough slope to detect. Now the crystal is
still responding to AM, but it's AM *you* generated in your high Q
tank. So is that receiving other than AM? Well, like I said, yes, no,
and maybe. It depends on how you define it.

I suppose that you could carefully design the filters on two crystal
sets to function as a slope detector for FSK or FM....  8-)

Generally, though, other modes require injecting the signal from a
local oscillator, and we're no longer dealing with a crystal set.

I have a Kenwood R-2000 with which I am extremely pleased. I was using an
"Evesdropper Multi-trap dipole" which worked quite well. Having recently moved,
and not having the space I once had, I find it necessary to use a different
type of antenna. Any suggestions out there? I am currently looking into the
"Active" type of antenna, particularly the McKay Dymek DA-100D and the Dressler
ARA-60. How do these two antennas compare with each other, and to the Multi-
trap evesdropper I was once using? I would greatly appreciate any response
inasmuch as I'm "chomping at the bit" to get started SWL'ing again. Of course,
any other antenna suggestions would be most welcomed.

Hi,

	I just found this newsgroup; so, please don't flame me if this is
a FAQ....

	I'd like to get into SW listening and would like recommendations on
what receivers would enable me to do the following -

 - Limiting price of 150
 - Pick up signals < 30 MHz
 - AM and SSB i.e pick up both broadcast and HAM transmissions
 - Be easy to tune, preferably digital tuning

	Optional stuff would be

 - Have higher frequency capability(VHF etc.) 
 - programmability etc...
 - possibility of later using it for HAM radio

	Any suggestions in this regard would be very helpful, particularly
info. about where to get such radios, whether used ones should be considered,
etc.

	If there is a FAQ for this group, do email it to me

	Thanks in advance,
