The second point is not necessarily true. The Lowe receivers, for instance,
have two DOUBLE SIDEBAND synchronous modes which do not remove interference
from adjacent carriers on one side. Their single sideband synchronous modes
do as you state.

You will probably get quite a few answers to this question, ....

Andy Sennitt, the editor of the WRTVH was in Philadelphia in Nov. finishing
the editing for the 1993 edition, so yes, the deadline for inforation is
usually listed as October -- however, he manages to get even later info
included since he's tied into several different computer networks and he
receives schedules by FAX upto the last minute.

The book went to the publisher, and should be out of the bindery by about
the 28th of Dec..... it was never expected to be out in mid-December.
Since it is now the 31st, I would expect that most folks that have
pre-publication orders should be getting them sometime soon (depending on
how folks like Grove, etc... handle the shipping).  For commercial bookstores,
it's hard to say when they might get them, but they should be able to get
delivery soon if they had orders placed.

Kirk Baxter,
Happy New Year to all!

This is the very hard way of doing it.  You can use an AM station to do
it and why not use WWV on 10 or 15 MHz as you know they are on freq?!

It really depends on where you are. In the US it is true that it is not legal.
The original poster requesting the information was in Australia. I don't know

Fellow SWL's:

I have been enjoying my Sangean ATS-803A for some months now, and I think
it's time to try something more.
I heard you can get RTTY signals and decode them with some hardware/software
and your PC and have all those news dispatches from wire services on RTTY
being displayed/saved.
I need some help on what to look to achieve those tasks:
* What kind of decoder should I look for?
* Will that decoder work somehow with my present portable (eg the ATS)?
* Will that decoder come with appropiate software (DOS or Win) to decode,
  capture, save and search for the right stuff?

*Given that all of the above are somehow fulfilled, what models/makes are
the best recommended under a very low budget (perhaps an used one could
be good enough)?

 I saw an ad from MFJ, the MFJ-1214, is this a good choice? Will it do the
 job?  Will it work with a portable?

 I will be calling MFJ but I will really appreciate some input from you
 on this matter.

YES!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
This is why when someone reports a strong signal, he is *rarely* close to
the transmitter site.  Even if you were 225 miles from the transmitter
site, the signal would not be impressive--HF groundwave attenuates quite
a bit faster than that of the broadcast band is is usually transmitted
by more directional antennas.

When I lived in Ohio, I heard signals that originate here in VA much
better.  Before anyone makes a comment on how a signal is so strong that
it must be close, I wish they would drive to an HF facility with a
HF reciever,  Take it from someone who has done this many times that
it is a real eye-opener.  If it is strong, it is almost certainly not
close.  If it is close, it is close enough that if you know the area,
you know the antennas.

What a load of horse manure.  Radio Amateurs have been calle hams since
the early 1910's.  NO one knows the real origin of the term but it was
widely used by ship to shore telegraph operators who would complain about
the damn hams messing up the comm links with their spark gap transmitters.

Nope. I think VOR is "Vector Over Radio" for pilots

Legend has it that it is a slang from the Brits: "Allo! Didja 'ear

> What is "BFO to hear SSB voice and CW (code)"?

Radio uses the heterodyne difference between a carrier frequency 
and another frequency to make the sound.  It takes two frequencies
to make it work.  Both SSB and CW have only one frequency (CW only
carrier, SSB only the second frequency)  In order to hear either,
a second frequency needs to be inserted.  That's what the BFO does.
Its full name is "Beat Frequency Occillator"  It inserts a frequency
for the signal to "beat" against, hence, making it audible.
 
> Why are some frequencies called 'meter', as in 10meter band?

This is the distance between the "humps" in the wavelength.  10 meters=
10 meters between "humps".  This is the "old" way of referring to
frequency and is a holdover from the "old days". The 10 meter band
is from 28.0 mHz to 29.9 mHz

No problem.  A good resource for this kind of thing is the ARRl Handbook
and the ARRL Operator's Manual.  One or the other of these books should
be available at a public library.  The World Radio and TV Handbook
(WRTH) would be handy for this kind of info (and other info also)
and any good bookstore can order it if it doesn't have it in stock.

A very nice review of PR-100 appeared in this group a couple of weeks
ago. Based on that I bought the radio ($39.95 + $4.95 shipping) from J&R
1-800-221-8180.

It seems to pull powerful stations (BBC, radio Australia, Netherlands,
NZ, Canada etc) quite easily. I live in Los Angeles (Western US) which
is quite bad for SW listening so I expect in other areas, it does even
better than here. I also had bought DAK's $69.95 radio which has more
bells and whistles but PR-100 beats it hands down in performance.

To add to the very thourough previous review, I will add the following:
-- digital screen has no lights ..tough to operate in dark.
-- Channel selector is mechanical, very hard to change ..I have a
   feeling that it would be the first one to break.
-- It will help a lot to get a spool wire antenna. 
-- 5 memory presets for each channel (am,fm,sw1,sw2) is not enough,
   atleast for SW frequencies.

Still, a great value and reasonable performance. If you, like me, are
interested in only the major broadcasters then you can not go wrong with
this radio.

The 7 MHz I mentioned is a terestrial microwave link.  Microwave towers
along a route from DC to NC support this circuit.  Sorry I was not
clear on that.  But unrelated but since you asked, the military DSCS II
and III satellites use uplinks and downlinks in the 7 GHz range.
