RITTY 4.0


RITTY 4.0 is now available. This release updates nearly
every aspect of signal processing. You'll find technical
details below.

RITTY 4.0 costs $100. You can upgrade from RITTY 3.0
for $60, or from RITTY 2.0 for $80. I no longer take credit
cards, but if you send a check, money order, or cash to the
address below, I'll e-mail the program when payment arrives.
For postal delivery on 3.5" diskette, add $5.


Signal Detection

RITTY 4.0 features updated detectors. The narrow
detector now has sharp bandpass filters for all baud rates, each
carefully compensated for intersymbol interference. This
compensation keeps a data pulse from interfering with its
neighbors, a form of self-QRM too often overlooked in casual
filter designs.

The polar detector has been completely revised. The new
detector uses channel filters that capture more power smeared by
ionospheric modulation. Though wider, the filters have steeper
skirts to better reject QRM. The filters have zero intersymbol
interference to permit recovery of signals that flutter right
down to the noise floor. Detection is no longer implicitly
hard-limited. This prevents noise capture of weak signals. The
new polar detector permits copy of RTTY signals so distorted
during magnetic storms that they sound raspy or hissy.

RITTY 4.0 provides a new detector for signals corrupted
by backscatter and other multipath effects. These difficult
signals, which ordinary detectors may completely garble, can
occur when the MUF is too low for direct propagation. In
addition to special channel filters with narrow impulse response
and zero intersymbol interference, the multipath detector uses
dynamic sampling to help reject power smeared by propagation
from one bit to the next. While the new detector won't
perfectly ungarble every multipath signal, it can help with
many.

Each detector has its own waveform color so you can tell
at a glance which is active. You can cycle through the four
detectors with a single keystroke. The polar and multipath
detectors are both available in WF1B.


Synchronization

RITTY 4.0 uses a new method to synchronize characters.
The method improves bit-sampling accuracy, especially for the
rounded waveforms emitted by the new detectors. It also speeds
character sync and makes false sync less likely. When you
return to receive, RITTY sequentially restarts signal
acquisition in a way that minimizes resynchronization time and
yields clean print more quickly.


Numerical Flywheel

The Numerical Flywheel now locks more reliably. It
better rejects odd signals with unstable character timing and
more accurately locks to noisy ones. A special feature enables
early lock by dynamically adjusting bit sampling while still
extracting accurate timing from a noisy signal. In RITTY 4.0
the Numerical Flywheel always remains locked when you switch
detectors. This makes it easier to determine the best detector
for a questionable signal by experiment.


Autotune

The Autotune algorithm has been completely rewritten.
The new algorithm is designed for multiple signals and works
especially well in pileups. A stronger signal that suddenly
appears in the Autotune passband no longer captures the filters
(unless the new signal obliterates the old). A faster Autotune
speed option allows RITTY to quickly tune the next valid signal.
The new Autotune algorithm was used at TX0DX and 4W6/N5KO.


Repetition Integration

Repetition Integration has been extensively revised to
more reliably detect and correct repeated text. It now has a
special mode optimized for repeated callsigns. This mode almost
entirely eliminates spurious detection. It's especially useful
for contests and chasing DX.


Transmit

When calling a station with AFSK Autotune enabled,
another station that calls first may capture Autotune and force
your call off frequency. To prevent this, RITTY 4.0 provides
AFSK Autotune Lag. This option delays transmit tone-frequency
change for one second after receive Autotune jumps to a new
signal.

RITTY 4.0 provides transmit word wrap. This lets you
type past the end of a line without splitting a word. RITTY
will automatically transmit a carriage return after the last
space and move the partial word to the next line.

You can transmit a canned message from receive mode by
pressing Alt-Fn. You no longer need to press Pause first to go
to transmit mode.


Clock Calibration

RITTY 4.0 lets you calibrate your sound-card clock to
WWV time ticks. Although RTTY mode is relatively insensitive to
signal timing, some sound cards are so far off that both receive
and transmit signals may be degraded. RITTY 4.0 can quickly
calibrate your sound-card clock frequency to an accuracy of a
few parts per million.


Miscellaneous Changes

RITTY 4.0 has a revamped squelch algorithm, gobbles
redundant carriage returns for WF1B, displays WF1B tuning pips
with greater stability and accuracy, consolidates narrow shifts,
can generate a TEXT file of unlimited length, uses faster and
more efficient code, has minor cosmetic enhancements, and
corrects several obscure bugs.

Re: Fw: RITTY 4.0

Andrew J. O'Brien <obrienaj@...>
 

I would arguer with Mike that this is VERY GOOD RTTY software, perhaps the
best copying performance of them all. I used a version that came out a year
or so ago, and had a bit of a dispute with the author (he was kind enough to
send me a copy prior to payment but it did not work fully, probably my
system not his software , we fell out over whether payment was still due).
Despite this I would certainly say that old version was great and the new
version sounds even greater. $100 seems steep in the days of free soundcard
RTTY software, but the version of RITTY that I tried last year was leaps and
bounds ahead of them all in the copy department.

If you are serious about RTTY DXING/Contesting this might be for you.

Have just spoken (if thats the right word) via ICQ to Andy O'Brien. Think
this makes a lot of sense. My only concerns were, that the Technical Hams
might have reservations to Amateur SWL combining in Andy's Group. However as
most licensed Hams started as SWL we do not think this will be a problem. I
have been in Andy's group from the start and have been recieved well.
After all both Groups are focused on Digital Radio Transmissions. Please we
would both like you to send in your comments, (even if we don't like them)

I noticed that since Andrew Nicholson and I set up two different digital
related "reflectors" around the same time, that several of us are posting
jointly to digitalradio@egroups.com and RadioDataRecording@egroups.com .
The former was mainly ham related and the latter SWL.

Since we do frequently cross-post I wonder if we should consider a merger
of
the two groups? Any comments

Hi All.
Recieved Throb on 3602khz, Loud and clear. Jose EA3VFE, Gerry E19FV sorry
about WX Gerry. Bernard G3JYF. Recieved and decoded 99%. Although print box
changed twice. Gerry and Jose was actualy stronger, Sorry Bernard. Good copy
all round though, AFC seemed to work this time to, only little red line
needed tweeking.

Re: [RadioDataDecoding] Two digital lists ?

Tony Chedester <abc@...>
 

Hi,
Name here is Tony. New to group but old to ham radio and swling. I also came to ham radio
through swling. As a newbie I should sit on the side lines and read the mail for a while, but I need to
respond to the suggestion to combine e-groups.
The appeal of digital modes to each of these two groups is diverse enough to require separate
groups; decoding various utility stations is quite different than attempting two-way contact using an
experimental digital mode.
If one is interested in both subjects, all they need to do is subscribe to both e-groups. For
someone else interested in only one of these subjects, the extra email from the other group adds to
information overload.
Thanks for the soap box, Tony

Paulus <paulstra@...>
 

Hello all,

Here are all the published programs of Lionel G3PPT.
Have an look at Slowfeldhell ( when you are used to Throb, I am sure you are
patient enough to try this mode which is very very senistive but an bit
slower then Throb (max 2 char/minute)).
Throb can be found on page3.html.
Best is to go to page2.html, and then change the webadress bij hand to
page3.html.
In due time I am sure, we can reach from page2 also page3


http://www.lsear.freeserve.co.uk/ or page2.html or
page3.html


Yes that was an good question, where is the Freezebutton? : There is none hi

Another thing is the Reflector: Suppose this one is ok ?


Cheerio now,

Re: throb

Paulus <paulstra@...>
 

Congrats Andy receiving Jose (EA3VF), Gerry (EI9FV) and Bernard(G3JYF) on 80
mtrs.

Do you know the QRG and Sideband they were using ?
Like Coherent-BPSK we could agree upon an QRG on 80 as well.

Re: [Hellschreiber] Re: Throb,Hell

DL2RR <dl2rr@...>
 

Hello,
the problem with the bad tuning seems to be a problem of installation or
kind of computer.
At one Computer, it works perfectly with the test signal, but there I have
no ham radio. It works rarely on the computer at the transceiver. Both uses
WINDOWS98. The one I'm using with hamradio is older amd slowlier (266 MHz
shout be fast enough). A click onto the waterfall causes a totally wrong
attitude of the red line. Sometimes it comes to the signal in small steps
(in the case of every click, a small piece). In the other window, I can
sometimes find no reflex at all.
Only if THROB works well with the testsignal, an online signal gives
positive results. Mostly temporary only for a short time. Few days before I
received a group (Fred(OH/DK4ZC), Chris(HB9BDM) and Pesi(G3NDO) after 'hard
tuning working' partial very good. Unfortunately, I received no answer at
my calls.

I have found, that it sometimes works after again pushing the SETUP button
without any changings. All is to some mysterious, and I am very much
dependent on trying out the use of the program. I expect, I find the cause
of the erroneous operation soon.

Hi
I to have problems reading Throb, someone was on 14062 (on my dial).
Realy
strong signal, Tried LSB and USB but no luck on either. Time 16.40utc
onward.
AFC does not seem to hold on signal either. Another annoying thing is,
when
listening there is no way of stopping the copy when there is no signal.
Does
anyone apart from DL2RR and myself have these problems?.
Regards and 73
Andy N.

Hi Paul.
Now you have realy lost me, I am a real amateur when it comes to Radio. QRG
(frequency) 3.602 mhz And they were using USB. Coherent-BPSK? Sorry over my
head that one hi hi. (Binary Phase Shift Keying), just looked it up, non the
wiser though. If there are any other SWL out there like me, the attached web
page is very handy for decoding The Radio Ham Jargon. True hams you can have
a look to, give you a bit of a laugh hi hi.
Seriously Paul, I am sorry that I can't give you a fuller answer, Maybe soon
as I am on a very steep learning curve.
Regards and Best 73s
Andy N.

Hello Andy,


Here are programs concerning Coherent BPSK.
But you will have to build an Reciever (A/D) converter and for TX and D/A
converter.
At the moment no RX soundcard program available.
There was some time ago an TX soundcard program for Coherent BPSK for Bill
Ve2iq, but no longer available.

I will send over the link to the Website of the Long Wave Club of America.
There is much more info, also about the Coherent-BPSK.

BTW: Sunday , starting at 2000 UTC (In the summer) on 3.586.000 we have an
Coherent BPSK roundtable.
Also during the week you can her on this QRG Coherent bpsk signals.

Cheerio now,
73 de Paul, pa0ocd

Hello.
I am running 500 mhz PC, Windows 98, Someone did not understand my comment
Re: Stopping copy on idle.
I meant that when a Signal stops or you are waiting for someone to return a
Call to another Throbber, that the decode boxes fill with unwanted copy. I
do not know if this is a problem for transmitters or just SWL like myself. I
was thinking along the lines of Hellscrieber where the copy can be halted.
Although I personaly find it annoying that the waterfall display also halts
on Hell. I tried on Throb selecting RX although then you can't hear the
radio signal over that of the RX wave. I copied several Throbbers last night
and am glad to say the AFC worked fine. I have no further problems and have
no difficulty with the red line on Waterfall.
Regards and 73
Andy N

Hello all,
Have an look here, there are more waves then shortwaves hi.

Somewhere you will find also info about Coherent-BPSK.
Will try to find more

Hello all,

On this website of K0LR, you will find more info about C-BPSK basics and
many other things.

BTW: C-Bpsk is not especial for Long Wave !
We had many 14 Mhz qso,s with very marginal signals only to be traced by
waterfall display and we noticed that on 80 mtrs with condx with strong
fasejumps/shifts C-bpsk outperforms psk31.

Hello Paul,

Yesterday on 80 m. band, EI9FV-Gerry and me EA3VF were using THROB mode in
USB Sideband: qrg was 3.602. Time was 22:00z.

Congrats Andy receiving Jose (EA3VF), Gerry (EI9FV) and Bernard(G3JYF) on
80
mtrs.

Do you know the QRG and Sideband they were using ?
Like Coherent-BPSK we could agree upon an QRG on 80 as well.
