I would be interested in knowing if anyone out there with an AOR
receiver and a RS232 port has had the chance to use the "Scanner
Control System" by Gesmundo Computing & Design.  This is the 
RS232 Control Package that ACE Communications sells as an option.
I have been using a program called SCANCAT for about a year now
with good results however I feel that it was not designed to take
full advantage of the AOR receiver.  ACE is sending out _FREE_
demos of this software and it doesn't look to bad.  Just wanted to
know if anyone has had direct experiance with it.

While we are on the subject of the software, the help screens also
mention additional hardware that can be added to the back of the 
3000.  This being a Radio Direction Finder and a Tone Decoder for
CTCSS/DCS/DTMF!  This has sparked an interest in where I may be 
able to find such a thing for my receiver other than ACE.  The RDF
just plugs into the speaker output and the Tone Decoder plugs into
something that I don't recall and the printer port on the computer.

For that matter, if anyone can comment on anything of interest here, 
please do so!  Thanks

This is an interesting phenomena that I believe I have explained sucessfully
in QST, the monthly journal of the American Radio Relay League, which caters
to amateur radio operators.

To summarize, there are two ways of matching FETs (or other active devices).

1.  Maximum power transfer.  Good old conjugate matching taught in
engineering schools.

2.  Best signal to noise ratio.  What good is a lot of power out of
an amplifier if most of it is noise?  

It turns out that these objectives can't be achieved simultaneously
in most cases--most notably with FETs at HF.

So, assuming that the radio is properly designed, you hear #2 with
an antenna of the right impedance and #1 when you hear that unusually
loud output signal while hooking up the antenna.

I've never heard RHC on mediumwave; then again, I've never looked for
it there.  I'll try to look for it tonight, although my location (urban
area with lots of RF noise, far from Cuba) makes it pretty iffy that
I'll hear anything.

Regarding audio quality, RHC often has poor audio on SW (under/over
modulated signal, distortion, hum, etc.)  They are also not very
precise about starting their transmissions -- sometimes they'll run an
interval signal for ten minutes or more, the transmissions often start
a few minutes later than they should, sometimes there'll be no interval
signal at all, just a blank carrier for five or ten minutes, then they
start broadcasting audio.  One time, I heard their interval signal get
"stuck" on one of the notes -- the transmitter then broadcast a
constant tone for several minutes!

Signal quality seems to be the worst at the beginning of transmissions
and usually improves after the initial five or ten minutes; one can
easily hear the signal change as technicians make adjustments to the
transmitter.

The OZ4 is(was) a gas-filled full wave rectifier commonly used with vibrator
power supplies. It required a minimum of 300 volts DC (1000 volts max) and
at least a 30 ma load.

It has two anodes and a cathode but no filament. Each anode was connected to
one end of the center-tapped secondary.

What you heard was MIDNITE RADIO and commentary from the Pirate Peanut
Gallery following their broadcast.  The voice mail number announced during
the program is a real working number, but if you'd prefer to write them a
letter, they use PO Box 109, Blue Ridge Summit, PA  17214.  Be sure to
include 3 units of mint postage with your reception report.

The Peanut Gallery has become one of the most interesting phenomena ever
to hit the pirate bands, in my opinion.  Instant audience feedback - and
it's brutally honest.

Your receiver must be receiving harmonics.  Most cordless phones operate on
10 descrete "channels" between 46 and 47 MHz.  Older ones operate just above
the medium wave band at about 1620 kHz as I recall.  Some brand new ones 
are at about 900 MHz.  I'm not personally aware of any that have encryption
of the voice data (unless they cost a small fortune, I would imagine).

The frequencies I posted are correct; the encryption issue I could be wrong
on.  I've certainly not seen any.

My thought is would it be possible to install one of those

Yeah.. that's what I was told by someone else too.  So, what kind of 
broadcasting equipment do these pirates use?  Where do they put their 
antennas?  If the antenna is in full view of everyone, then it would
be easy to get caught.  No?  Is there some way of hiding it?  Hmm..

What is the best source of information for whether or not an FM broadcast

from FM-Atlas, but would like to know, first, if there is anything near me
to listen to.  If you can pick up the FM station itself, is it safe to say
you can generally decode the SCA? Or must the FM reception be above average
to recover the subcarrier signals?

The biggest problem with the HQ-100 is that it is single conversion
(subject to images, especially above 20 MHz) and doesn't have fantastic
selectivity.  It is not a problem, but its specifications aren't as 
good as Hammarlunds better double/triple conversion receivers like the
Hq-160 and Hq-180.

I've owned the HQ-100 (a few years back) and was pretty happy with it.

     I think one of the programs might have been R Australia's special
service to Papua New Guinea (which is in English and Pidgin) but the
transmitter is surely within Australia itself ?

      Many of the big international broadcasters do have specialized
programming directed towards different parts of the world in addition
to a mainstream "world service", if any. These  usually have more
in depth coverage of regional news or in the case of R Australia,
sports. In fact during the weekends last month, one could have heard 
four different programs from R Australia. They usually have sports on
some frequencies on Saturdays but because of the the world cup cricket
they even had two different sports channels; one carrying the usual
mixture of sports and another devoted exclusively to cricket.

     Come to think of it, N America is perhaps the only continent not a target
of specialized programming from any of the international broadcasters.
