I doubt seriously that the AM or FM guys are very concerned about us. I
really think it's a measure the FCC uses to keep their organization
reasonable. They have various services, domestic and international, with
specific rules, and they don't want too much mixing so they don't wind up

That's strictly to keep the riff-raff out from what I understand. I could
be wrong, though. I've never thought to ask them about it.

The basic difference between synchronous detection and Exalted carrier
(using a product detector) is the synchronous detector has a phase lock
loop which locks to the incoming carrier. The sound quality is much better
than exalted carrier because the phase of the oscillator used in the
product detector is of propper phase with the original transmitted signal.
Exalted carrier detection the Beat frequency oscillator is not lock,
it is free running, and gives a kinda of donald duck sound to the audio.

Many synchronous detectors also incorporate an audio phase shift network
which will provide upper and lower sideband selection. This is a
different method than recievers with standard product detectors. Here
upper and lower sideband selection is actually achieved before detection,
at the I.F. Level. The synchronous detctor does it at audio level. The
ultimate in interference rejection is achieved when both are used at
the same time.


I have designed and built a synchronous detector to be used with
recievers with a 455 khz I.F. output. It provides about 30-40 db
of unwanted sideband rejection. If you are electronically inclined,
and want a copy of the circuit, send SASE to Chuck Hanavin, PO Box

Jack, I answered this over a week ago. Maybe two.
Only the HF-150 has a double sideband synchronous mode.
In fact, it has TWO of them, one with extended treble response.

The HF-150 OUTCLASSES the Sony 2010 in performance. A comparison
between the two is not valid, in my opinion.

Dunno.

        I got the same message about the IRC's.  Since the message came with
the latest schedule, which in turn arrived a month after I had received the
same schedule on this list, their letter went in the same garbage can that
I had tossed the latest edition of BBC Worldwide.  The comparison between these

Yes, at the beginning of a transmission they go thru a handshaking
routine that establishes a number of parameters, including speed.

You're not simply going to be able to read a G3 Fax signal with a 
scanner and send the audio to another fax for display, although I think 
you could with the old FM G2 faxes.

Your best bet would probably be with some of the software methods of 
converting various formats as used with some of the computer based fax 
receive systems.

Subject: Antennas: general question
Followup-To: rec.radio.shortwave
Organization: pubs
Date: 11 Jan 93 16:55:34 CST


To sum up my question, what's the best antenna to get?  I hear lots of
discussion of antenna types, but significant voices (such as Harry
Helms) keep saying "none of those things will do any more than a
long-wire".

[I've been away from shortwave for a long time.  I bought a used Icom
R-71A, but I'm not getting the results I think I should get--only the
really powerful mainstream services, whereas the things I want to hear
are at least a little hard to get, such as Iraq.  There's some chance
that the Icom isn't up to spec, but it *looks* immaculate.]

I'm using the Eavesdropper antenna, which uses traps to resonate at the
broadcast bands.  I've heard that traps and coax lead-ins both entail
some loss, so I'm going to change, but to what?

Page 44 of Passport advertises Alpha Delta's DX-SWL antenna:  "Efficient
multiband frequency selection by means of special RF choke-resonators".
Is this any better than a tuned long-wire?  How important is tuning?

One more question: I wonder if it would make sense, even with a simple
antenna, to use a coax lead, and mount a preamp outside at the beginning
of the lead-in.  I was thinking this would be a way to prevent noise
originating in one's house.

Advice appreciated...

Maybe it's time to start cray.radio.shortwave.

On most radios, strong signals sound nice, and weak ones don't. In other
words, if the signal you want to hear is sufficiently far above the noise
floor of your receiver, you'll be able to "read" it. In order to predict
this, you need to know the field strength of the signal of interest at
your antenna, the gain of the antenna, and the sensitivity of the
receiver. If the voltage delivered to the antenna port of your rcvr is
below the spec sensitivity level, the signal will be swamped by receiver
noise.

If you're trying to listen to a relatively weak signal which is in a
channel adjacent to your non-favorite stateside religious broadcaster,
you will care about the adjacent channel rejection spec of your receiver;
in other words, how steep the skirts of your IF filter are.

And, finally, if you're listening to a signal which doesn't exactly
qualify as "strong" because it's competing for audio energy with
broadband noise, receiver distortion, EM phenomena, adjacent signals,
image frequency signals, or strong out-of-band signals causing spurious
responses, it'll be really nice if your receiver has audio stages with
bandpass which closely approximates the spectral characteristics of the
human voice you're listening to. In fact, some radios have such lousy
audio that you get tired of listening to even VOA real quick.

It sounds to me like what Johnny really cares about is this last issue.
In the price range he's talking about, he really doesn't have to worry
about sensitivity, and probably not adjacent-channel interference very
much. I think he wants nice-sounding, well-designed audio stages, which
Sony is not known for, and Grundig is.

DISCLAIMER: I have neither of the radios Johnny is considering, and have
not actually used either of them. This post is based on totally
unsubstatiated rumor and irresponsible innuendo.
