I use USB dfor FSK, simply because I want the low side of the signals to show
up on the left side of the waterfall, and the high frequencies to show up to
the right. Because that puts me opposite than the "normal" signals, I run both
send and receive with the reverse button clicked.'

A minor but annoying problem I'm having is that in Windows XP
it keeps maximizing the window without being told to. I haven't
found for sure what triggers it, but just now I am monitoring
and a ROS signal came on and a second or two after the initial
tone the window maximized itself.
Yup, just ha
of a sudden, when i click on any of the buttons, i see no text show up

Of course.

My "experiments" (many receptions and 2 transmissions) today with
ROS 1 and ROS 16 shows that it is quite an effective mode.
Congratulations Jose. Of particular interest to me were the several
occasions where I decoded a signal that was not visible in the
waterfall or audible to my ears. It w
IMO, ROS is not *true* SS in the legal sense. Other posts I've read cite an
FCC reference that SS involves spreading the signal EVENLY over the
bandwidth. ROS is using 16 DISCRETE tones to modulate, with a lot more
empty space than actual signal. I'm curious how much of spread spectrum's

still having problems, still no text showing up in rx or tx.
where is the station info stored ? i deleted all the program, and still when i
reinstall, the info comes backmaybe i need to delete that whereever it is
to get the text bug out.

pse email me personal if you got the
interesting problems with new ROS, but is to be expected
since i lost the text displays in the program, i did system restore and got the
problem solved. however the personal info is still stored somewhere i dont
know. it did not show the station info however this time.
is fun.

There in Europe, you have dozens of "local" governments to satisify, in the way
of modes and power, bands, etc. Im always supprised to find two governments
over there, who agree with anything another two may want to do on the bands.

the program author mentioned that when he tested on 40m, that he used LSB.
this is not really a problem, but i think the digital community has pretty much
setteled on USB for all sound card digital modes. even some of the AFSK/RTTY
people use USB.
before too long, got to get it setteled in.

I have seen this too and at times wonder why.
I think maybe because the other modes are USB.
I got into RTTY in 1976. Still use a machine for RTTY.
The answer is in Wikipedia for Spread Spectrum.

Andy,
I'd be more than happy to run ROS through the path simulator if I could get the
program running w

So the plan would be to get rid of the loud European & US stations, and
just leave the ( presumably not-loud?) UK ones on the air? :-)
Sounds workable to me, we could all dig out

Is ROS actually a spread spectrum frequency hopping mode or more like CHIP?
I have not seen any published modulation scheme/protocol specificaions so
guessing.
I certainly doubt the -35dB claim without even anecdotal evidence...otherwise
for EME I now have a 10dB path margin :)

All,
The latest version of ROS seems to work fine with Vista.

Yo only have to download the sound archive: "The Man Of the Vara at 1 bauds

I made the experiment over AWGN and ROS is 2 dBs better than OLIVIA 32/1000.
But we are comparing two modes at differents character rate. As you know ROS is
two times faster than OLIVIA 32/1000.
You should compare ROS 16 with OLIVIA 8/1000. Then the different is about 5-6
dBs for the same char
Very impressive Jose, again...congratulations.
