[digitalradio] Olivia Signal?

[Rui Manuel]

Just curiosity

Can anybody identify what mode is using a signal on 3.733 (80m).
I am trying to decode digital sstv on that frequency, however most of
the time I hear a clicking multitone sound like Olivia sending
beacons, maybe trying to establish  a connection, it keeps
transmitting multitones for a while, sometimes more than 2 minutes,
making my decoding a mess.
The beacon of the signal usually starts with several digital carriers
sweeping in frequency  on the waterfall, large bandwidth and when
transmitting the multitones make a characteristic picture of small
squares like a chess board, I don't see any pilot carriers.

Well, what I meant (I don't remember the exact quote right now) is that 
the steering wheel and the pedals remain in the same place and react in 
a similar way, you don't have to learn anything basically new. Highways 
don't need to be modified, either...

[digitalradio] odd signal on 80M?

[Andrew O'Brien]

Several of us in a regional et o 80M heard an odd sound  every few
mniutes .  Sounded like a space ship taking off.   check the sound via
http://www.obriensweb/com/odd.wav


You can hear it changing in pitch, I re-tune  evrry few seconds.  I
followed it from 3832 LSB to 3825, it keeps o going and then returns
to 3832 for a re-do.

Military?  It was heard by some hams 175 miles away from me.

That's interesting, because I think it was GM that is generally
credited with inventing "planned obsolescence" and the annual
model change.

That's interesting, because I think it was GM that is generally
credited with inventing "planned obsolescence" and the annual
model change.

John,

It is the ongoing fashion, nothing else. Life cycles are shorter 
nowadays. There are many old american cars from the fifties running in 
Havana streets, and even a few Model T Fords too, that tourists love to 
see. They were built to last.

Modern operating systems are short cycle mutants. Quite often, the 
change is introduced seeking for profits, and nothing else.

I am not against changes for better, but there was a GM - Microsoft 
controversy that ended with a caustic reply from the GM's President
that explained it too well.

One very important reason is (I)nter (S)ymbol (I)nterference, or ISI, 
when one delayed (by multipath) symbol steps on the following one, 
confusing the demodulator and creating lots of garbage. A long symbol 
may allow reflections to die and the demodulator to output some 
meaningful data, but a shorter one also has smaller probabilities of
"hitting the nail on the head". The idea of longer symbols crafted for 
multipath environments is exploited in OFDM systems, together with some 
measure of FEC, if not using also ARQ, to assure the correct reception 
of "data", whatever the message content may be.

Services Software, Inc. (CSS) today announced the availability of EmComm
Ops™, a new software solution for packet radio operations. Designed
primarily for emergency radio communications, EmComm Ops helps amateur
(Ham), commercial and MARS radio operators connect to, access, integrate
and operate packet radio stations with a Windows PC or laptop from a
fixed station or in the field. EmComm Ops is the first addition to CSS’
recently-rebranded Radio Operations Center™ (ROC) product line.

response to the recent re-introduction of TNC solutions by MFJ Enterprises.

> At an introductory price of $29.95, EmComm Ops offers radio operators
an efficient and affordable entry into advanced software-enhanced packet
and radio control. For operators who require support beyond packet

the classic HF digital modes, as well as support for soundcard-based
radio modes including PSK-31 and MT-63.

Operators can control radio transmissions while simultaneously running
logging programs, call book programs or any Windows application

conditions limit reliable radio operation, messages can be noted in a

re-transmitted at a later time when conditions improve. Operators can
also export messages to a file to document communications. Of course,
