Mike, could you compare the Lowe recievers to the Sony 2010, etc.  What
models have this DOUBLE SIDEBAND synchronous mode?

I've been seeing the Solar Geophysical Data posts in this area for quite 
some time and was wondering how to read them?!? What things should I be 
looking at to see how my hearing of various stations is going to be 
affected? Is there any info someone could post here to make this 
information make more sense to me?!? ;-)

I just bought a Grundig Satellit 500.  Presently, I am using about a 15
foot long wire strung aroung a room -- I live in a high rise building.  I
am able to receive all of the usual strong stations; but I wonder if any
of the active indoor antenna's being marketed could improve my reception.
 I would appreciate comments on the utility of these active devices.

WHRI is an entirely legit station that has been around for some time.
They have two 100 KW transmitters in South Bemd, IN and do ID as World
Harvest Radio International.  Address is PO Box 12, South Bend, IN
46624.

Keywords: mods
Organization: AT&T
Date: Fri, 1 Jan 1993 03:39:55 GMT


Tweak AM rcvr 4 1700KHz
The AM broadcast band is expanding up to 1700KHz soon, and some AM 
radios can be adjusted to accomodate this new spectrum.  The 
radio should have vague calibrations, as the calibration 
would otherwise need to be changed.  We're talking about analog tuned 
radios, like cheap portables or clock radios.  
Practice on a radio you don't care about before you attempt a good radio!
Step 1:  You'll need a 1700KHz signal source, perferrably AM 
modulated with a tone.  Also tunable to the range 530 to 
1710KHZ.
Step 2: See how far the radio will tune before you touch any 
adjustments.  Maybe it already is capable of getting 1700KHz.
If not...
Step 3:  You need to identify the purpose of all trimmers and 
adjustments in the radio.  Assuming no RF stage, look for: antenna 
trimmer cap, oscillator trimmer cap, oscillator tank coil, Antenna 
loopstick (hopefully, the wire is wound on a slidable paper 
coilform), and the IF coils.
Step 4:  Mark, with a fine point magic marker, the orginal positions 
of all cap and coil adjustments, so you can return them to their 
orginal setting if this procedure doesn't work out.  Look to see if 
the osc and ant trimmer caps are currently set at about their 
midpoints, not at or near minimum capacitance.  If they are near or 
at minimum, stop.  This procedure then won't work with that radio.  
Step 5: Set the signal source to 530 KHz, and check that the radio 
can tune that in, and then see how far the radio can tune the upper 
end.  Also tune in radio stations of known frequency and zerobeat the 
generator, as a check on the generator's accuracy.  Now find a 
station at or near the top end of the band and "walk" it doun your 
dial a little bit  by making small adjustments of the oscillator 
trimmer (turn for less capacitance on the trimmer).  
Tune to the bottom of the dial, and adjust the osc coil to bring back
the bottom of the band (530).  Repeate this process a few 
times, as you walk the station at the top of the band down.  Check to 
see if you can receive your generator set to 1710KHz yet (Gives 
the radio a little leeway for temperature and whatnot drift over 
time).  
Step 6:  Now that the radio can tune 530 to 1710KHz, you'll need to 
tweak the antenna LC circuit.  Tune a station near 620KHz, and slide 
the antenna loopstick coil (avoid putting your fingers on the coil 
itself, touch the ends of the coilform with fingernails or such) 
for max signal strength.  Now tune a station near 1480KHz, and tweak 
the antenna trimmer cap.  repeat process a few times.  

You shouldn't need to touch the IF strip.

That should do it.  Enjoy the new stations when they sign on.
Proceed at your own risk

Hmmm that would explain why I haven't been able to tune them in lately!

A good source in the states is Bruce Elving's FM Atlas.  He's at PO Box 336,
Esko MN 55733-0336.  You can request a free catalog, which includes already-
modified radios as well as modification kits...or Bruce will do it himself

The sony 2010 is generally considered an excellent portable world
band radio. I dont think there are any major problems with it except
for one: The wide filter. Its about 12 khz wide. This results in
a 5 khz heterodyne alot of the time. (very irritating). Replacement
filters are available, exact fits, just under 10 khz wide. The replacement
filters are from a third party and you solder them in yourself or pay
someone else to do it for you.

The sw55 is also an excellent reciever. It shouldnt have the filter problem
as they say the wide filter is 8 khz wide. The sw55 does not have synchro
detection like the 2010 although the sw55 is more expensive.


the sw77 is the most expensive of the 3. I dont know very much about it
except for it has synchro detect and a text-readout (alpha numeric)
of whatever station you are set on. (e.g. R.JAPAN) Presumably it comes
programed with the more popular stations and you can put your own in
too.

For sale - a Sony ICF-2010 shortwave radio in excellent condition.  This radio
is considered the top of the line in portable shortwave radios. It's about
2 years old, only used for the 1st 6 months (after which I bought a PC, now
my primary hobby, haven't used radio since).  Coverage is from 150 KHZ-30 MHZ
AM, 76-108 MHZ (FM), and 116-136 MHZ (Air Band, i.e. airline traffic, control
towers, etc.). Also includes upper and lower sideband (can listen to ham radio
on upper sideband), 32 memory channels, synchronous detection for
interference-free reception (I've picked up over 30 countries so far from here
in West Central Florida), digital tuning, many other options which make this
an excellent choice for shortwave listening.

Asking $200 (goes for $350 new), I'll pick up shipping to you.  Contact me
through this conference or at (813)786-8944.

This talk about WFLA brings a thought to mind.  Just a few years ago, in what
was called the Iron Curtain countries, some poor soul could become a
criminal by just tuning his radio dial to the "wrong" station.  Well,
Communism fell.  The jamming stopped, for the most part, and now, citizines
of those countries can tune their radios to almost anything they please.
	The U.S. Congress, (best politicians money can buy), thought that
it would be really neat to eradicate the problem of electronic snooping
on mobile telephones by spreading ink on paper rather than providing for
encoding of the signal.  The broadcasters bought a few drinks or Lord knows
what for the right folks and broadcast remote pickups were also included
in the Electronic Communications Privacy act.
	The bottom line, here, is to be careful.  If you don't want to be
carted off to jail and become a real live criminal, you will have to
report any remote broadcast DX from one of the freeer countries in the
world.  The ECPA, in its present form represents a truly dark chapter in
American law since it unknowingly makes criminals out of almost anybody with
a general coverage receiver.  So what if it hasn't really been inforced;
it is there just waiting to trip somebody up.  It is the legal equivalent of
a fraid electrical cord or missing stop sign.

Could someone post a current Schedule/FREQ/TIME list for Radio HCJB 
please? Tried tuning in the english broadcast at the time stated on my 
old schedule but it's changed to the South Pacific (japanese) broadcast 
at that time. Would sure like to get back on track by Saturday. (DX 
partyline broadcast)....
