	I just bought the DX-390 radio and I have two questions.

1.) Does anyone post a list of SW band radio station frequencies?

2.) I live in an apartment on the lower floor, (NO yard). What kind
    of antenna should I rig together to improve reception?

 One of the most popular subcarrier is the Mainstream FM subcarrier
  service carried by many cities.  This service is an amplitude modulated
  high speed (approximately 25Kbps) system which time multiplexes MOST
  news and stock services.  This includes AP, Reuters, etc. sent via
  a packet scheme through synchronous data.

  Anyone demodulate this signal or have more info?

Radiofax has been mentioned on this list several times, so I the
following may be of interest.  This is information direct from the
station as appearing in Contact, the World DX Club's bulletin.

"The Department of Communication in Dublin has told Radiofax that we are
causing some embarrassment to the Republic.  They now wish unlicenced
activity to cease and we believe the long term interests of Radiofax are
best served by closing down.  We have contemplated ignoring the request
but there is hope that independent shortwave licensing will be considered
in the future.  Unfortunately we can think of no other place to go that
would allow Radiofax to operate in a professional way.  All the 44 people
involved in Radiofax would like to thank our listeners for the 3000
letters of support for the project that you have sent us each year.  If
that number of letters went to Members of Parliament then perhaps
independent shortwave radio would happen sooner rather than later.
The other person you might write a nice letter to, saying how you value
what Radiofax did and requesting a licence is: The Minister of
Communications, Dublin 2, Ireland. ... We have a special telephone number
where listeners can record their opinions and reactions: 0483 272 888."

It's not AM vs FM, it's VHF vs HF.... The higher the frequency, the less
sky wave, and the move ground wave, in terms of how the signal is propogated

Though, there may be related reasons why AM is used in the HF broadcasting
bands, and FM is used in VHF, I've no experience with, say 10M FM, though
it's notable that there is none below a tiny sub-band there ... Perhaps
it's bandwidth related. There being less at lower frequencies to go around, 
and thus the need for conservation of band allocations vs high fidelity.

At any rate, the problem you're having is not AM vs FM, it's HF vs VHF.

Enjoy....

Any Elmers out there want to take this on? I'd like to see where I'm right,
and where I'm wrong... :)

It was very surprisingly event for me. Please read it.

Maybe u know, i have a SONY ICF-PRO-70. Last Friday, my daughter (3)
has exerted a pressure on the receiver by her feet. When i went to
home at evening and turned on my receiver, it was receiving 30 MHz.
I begun to scan other frequencies and i saw that it can receive
all other frequencies between 26100 and 87500.
I could see other mode indicators displayed by the receiver on screen.
It was VHF for the range of 30000-50000 kHz, and SW for the frequencies
less than 30000 kHz and beyond 50000 kHz it was FM. Also i saw another
mode indicator ( N.FM ).
Eventually, i removed its power jack, all these scene was over...B-<(*

I have contacted several contributors to this net and the following
picture has emerged so far:

1. The "old" Sony ICF-SW77 has NINE segment whip antenna and
   a serial number in the order of 30 000.
2. The "new" unit has ELEVEN segment whip and a serial number
   in the order of 900 000.
The antenna is 34 and 44 inches long, respectively. In the US
and in Germany the local Sony distributors put a dot on the
labels (those on the box) to mark the "new"model.
The type and colour of the Sony sticker placed on the speaker
appears to be unimportant, although gold stickers apparently
indicate the "new" model.

In places like Far East, Australia and New Zealand (and perhaps
others as well, please advise) SONY is dumping the "old" model
even making a fuss by "introducing" or "releasing" it to the
markets. The local dealers, even the local Sony offices, are
completely unaware of the problem, never heard about the model
being withdrawn from marketing a long time ago and consequently
are unable to advise customers.

If you have more information about this unpleasanat affair

   What signals there are are like the SAP, mostly narrowband FM
   audio or FSK or PSK modulated data signals in the 57 to 95 KHz
   range.  They are called SCA subcarriers (Subsidiary Communications 
   Authorization.)
   Not all stations have them.  As they can decrease the quality or
   range of the station, some stations don't bother.  Classical
   music stations that are picky about their signal are a bad bet.

Boston WCRB, a commercial nominally classical station has two awful
SCA channels, making the station almost unlistenable on a large
fraction of the cheaper receivers.  You'd think they would figure it
out.  Here's a rundown of the local SCA activity in Boston (now about
a year old).

Boston area FM SCA broadcasts

Freq.	Call	SCA channels/programming
88.1	WMBR	encrypted AP news data subcarrier
88.9	WERS	67KHz FM carrier (voice) 92KHz (5KHz dev) data

Some days ago I posted this question, but seems that it
didn't make it to the list. Here it goes again:

I will be going back to Europe in december 1992. A friend of
mine has a Uniden Bearcat ??-100 scanner (don't remember the
model) for sale, and I wonder if the frequencies this
scanner covers will be any good in Europe. I seem to
remember that police in Spain used the 84-88 MHz band, which
is not covered by the scanner because it corresponds to TV
here in the US (I could receive these frequencies by
shifting down the frequency range an old FM receiver).

Does anyone have a list of the VHF and UHF band distribution
in Europe? Would you please e-mail it to me?

Thanks!

This might be related.  The BBC on 5975 is prone to strange interference.
One day the audio sounded a bit off, until the BBC signed off.  And then
the RTTY signal that was straddleing the BBC carrier became evident.  
( I wonder what sort of Terminal Unit they were using that could pick up 
that signal.)  It happened more than once.  The next time, I turned on the 
BFO and tuned the carrier (and RTTY) signal for an reasonable (500 - 
1000 Hz) beat tone.  That brought the RTTY signal out from just being a 
strange distortion to an audible FSK signal.

I couldn't tell you about the FM CB, but as for the AM/SSB CB, I
heard one Sunday some time ago on RNI, a caller to Al Weiner's show
stated that he had made contact with Australia on channel 38 USB, no
linear on either end, i.e. 12W PEP both ends.  This would tell me
that the same channels are probably in use down there.

I would be interested to see how FM CB sounds in comparison to
AM/SSB.  I think I would still opt for AM/SSB due to price and the
fact that the capture effect on FM would make it easier for one
CB'er to completely block out another.

I've had sort of the same thought.  My idea would be for the manufacturers
of these hand-held counters to have some type of switch that would cut in 
a low-pass/high-pass filter of some type.  Most of these counters cover
the 1 Mhz - 2000 Mhz range.  It would be nifty to be able to filter out,
say, the FM Broadcast band (88-108 Mhz), and the TV bands (54 Mhz-88 Mhz
& 174 Mhz - 218 Mhz).  Or maybe have a series of filters, in 100 Mhz
increments.

I am in the market for a hand-held freq counter.  It'll be used 
primarily in conjunction with a scanner to determine the frequency 
of nearby hand-helds.   
 
I think I've narrowed it down to 2 choices.  Either the Startek 15 BG
(around $199) or one of the Optoelectronics models.  
Basically, it needs to cover 1 Mhz - 1200 Mhz and have relatively 
high sensitivity.  A signal strength meter would be nice but not
essential.  I also have a preference to LCD displays vs. LEDs.

Suggestions ?

There is no way to get the S-meter on the Drake R8 to report through the
serial port. However, there is a kind of clooge which allows spectrum
building of a sort.

The carrier detect line reports the presence of RF above the squelch. Now
you cannot have the computer adjust the squelch level, so we assume it fixed.
(I.e. let's not require the human to twiddle anything). The computer _can_ 
tune the R8 and adjust the filter width, and adjust the pre-amp, which is
in front of the squelch. Taking the power spectrum to be a random variable
with a certain variance, we can have the computer arrive at an estimate of
this by estimating the probability of observing carrier at various frequencies.

You have the computer generate frequencies, filter widths, and gain settings
by using a Baysian model, based on the fact that the power spectrum is well
modeled by rational functions, which cuts down on redundant queries. (I.e.
you query the radio with settings which are the most uncertain according to
your model).

This trick works OK if you have a slowly changing spectrum composed of resolved
stations. It isn't useless, since it can "discover" a weakly resolved station
but it ain't like you can talk to the S-meter. Not hardly.

The roofing nails I've used are a little over an inch long. Those were
for asphalt shingles, not cedar shake like we have in the Northwest, but
that's probably what Chaim has over his attic in Philly.

Roofing nails spaced at intervals on the order of those at which roofing
nails are usually spaced (16 inches laterally, and 6 or 8 vertically)
could have a significant shielding effect at the frequencies of interest;
however, by the same token, scattering from the nails could also interfere
with the pattern of an antenna mounted *outside* the attic but near the roof.

Probably best to try it and see if you're happy.
