By the way, nino IZ8BLY is working on a Win 95 version and we might have a
first cut of that to
play with very soon. I'll keep you posted.

I am looking forward for MT63 S/W FOR WINDOWS 95 AND I PERSUME IT SHALL
BE USED IN CONJUNCTION WITH THE SOUND CARD.

Hi folks,

I feel that it is time to give the MT63 web site a rev-up, since we have new
software
on the way. If you have any comments or suggestions you would like to make
regarding the MT63 web site, please let me know.

If you have software etc. to contribute, let me know that too.

You didn't know there was an MT63 web site? Shame! Check out

Hello,

I am testing a new program for MT63 for the windows+-soundcard
environment and need someone to qso with.

If you have an EVM unit and want to help please join the
following skeds:

tue 18-nov-99 19:00z 14.347 USB, MT63 bw+AD0-1000Hz, interleave+AD0-short
fri 19-nov-99 20:00z 14.347 USB, MT63 bw+AD0-1000Hz, interleave+AD0-short

Please be ready to switch to feldhell in case my MT63
program fails. I will randomly check 7097 USB in case
the condx on 20 mtrs are not good.

Thanks for helping,

Nino,

I would like to offer help with tests, but fear propagation
wont be too favorable -- perhaps someone in Europe can help?
There may be a possibility between 03H00 and 06H00 UTC, but that
would be a very odd time for you unless you are very keen.

It may be worth testing with an EVM to make sure? I have found
that very useful to test/verify the Linux MT63 which turns out
to work very well on the HF channel simulator down to at least
0 dB SNR on a CCIR POOR path.

Good luck!

Johan, KC7WW

Subject: wich MT63 version

Send Email Send Email
 
Hello,

regarding on wich modes of MT63 I've implemented in my program,
we will have all of them: bandwidth+AD0-500, 1000, 2000
and interleave+AD0-0 or 1 (short/long).

BTW, is there any standard nomenclature? I mean something
like +ACI-martin 1+ACI- for SSTV - a way to quick define
all parameters without any possible ambiguity.

Another point: I am simply adapting the program under Windows
95, all the source code is from Pawel SP9VRC, in other words,
he is the person we have to be grateful to :-)

About the skeds, it is difficult to establish a good time
for everybody... I think the best thing we can do is to make
a proposal for a net on this mailing list and wait for people
to join it (i.e. what was saturday afternoon for Hell on 14.063).

Anyway, at this stage, I simply would like to give an answer to
the question: +ACI-does it works?+ACI- :-)

Nino,

Yes, it sounds like a good idea to use the Varicode, especially when it
also gives multi-language support.

I agree with you about improving the speed of 500 Hz version. One thing
though, I have never been able to try the 500 Hz version because it would
not work on the EVM.

I think it would be REALLY good to be able to change mode from the UI
screen.

No, there is no suitable naming convention at present. All we have done
is use the EVM file name. Perhaps you should suggest something
more obvious. Maybe A, B, C for speed, and 0,1 for interleave?

Then A0 would be 500 Hz short interleave and C1 would be 2000 Hz long
interleave. That should give us plenty of room for expansion, and be
easy to send. Then we could put a CW ID on each transmission
(which is important, as it is the only way to identify it+ACE-) like

+ACI-de ZL1BPU MT63 B1+ACI-

Yes, I agree, just post your operating time/freq on the reflector,
and we will all try to meet it. I will do the same, but for now I
will use the EVM version.

By the way, do you know what PC speed is required for your test version?
I guess I should find out if it works with my P60 and report back.

Oh, and THANKS VERY MUCH to Pawel+ACE-

73,

Murray

(I love the idea of HTML+ACE- - but you then have to put an HTML interpreter in
the UI)

I am not sure what your AD0 means ? Is this the integrator length.
Folks using the EVM does not know about that one because
it is not available. For MT63 the parameters are simply
bandwidth and interleave factor. On Linux it is "-i" and
"-B" command-line switches that EVM users need to know.

Not that I know of.

PS. If you need help in establishing baseline comparisons -- I
have for MT63: Linux, EVM, and Win98 and use of an HF channel
simulator. MT63 Linux runs very well on a CCIR POOR path at
0 dB SNR.

Johan,

It would be great if you could run all the different versions of MT63
through
the simulator.

In fact, I am hesitant to suggest it, because I know it is a lot of work,
but I would LOVE to see the reults of running all the IZ8BLY Hell modes
through the simulator. We have a reasonable idea which is best under
certain conditions, but no accurate idea of the sensitivity.

This is of course why I am interested in getting hold of a software
ionospheric simulator, even if it isn't real time.

Hello All,

Using the Beta 0.9 MT63 SB version, I got an strange error, which hanged the
PC here.
Running Win98 SE , and the error message was: +ACIAIg-20/12/99 is not an valid
date+ACIAIg- ??.
No idea where that date came from.

The problem could be solved here by using the short Date notation: dd/MM/jj
( the old config was dd-MM-jj)
See the Control panel, Country properties, Date and change the short Date
notation.

I think all is running ok, but have to test it out with other stations hi.
Perhaps 1 khz wide, long cycle, USB 14.347 could be an good start ?
Like to have also other QRG's perhaps on 3,5  7 and 10 mhz ?

Can be QRV tomorrow Saterday afternoon and evening.
Will look around at 1300 UTC -1500 UTC and 1900 UTC - 2100 UTC on 20 mtr

Cheerio now

Hello all,

We just finished an long test with  MT63 for the soundcard ( Beta 0.9 on
Nino's website)
YL2KF , IZ8BLY and myself could chat for about 2 hours using the 500 hz, 1
khz and 2 khz mode with long interleave.
The 1khz and 2 khz could combat perfectly the QRM (strong fone signals and
even strong psk31 there hi), and our signals were weaker then the QRM !
I tested the compatibility during this 3 way QSO with the EVM56 for the 1
khz and 2 khz mode, and all was compatible.
Will have to do the 500 hz mode on EVM56 soon.
So well done Nino !

You have to set the Date format to dd/MM/jj , but it will be changed soon in
an future upgrade.
The & (ampersand) character will finish the TX but problem is an bit that is
not sure if all typed characters are being send.
So best not to type to fast hi hi.

Hearing again around 14.347 USB MT63 signals so will look aorund who is
there.

So give MT63 SB an try soon.
Best is we agree on calling CQ for the 1 khz wide mode with long interleave
using USB !.

Cheerio now
have an fb weekend

I am happy because all worked perfectly and despite of the bad

Congrats to everyone, and especially Nino for his software!

Well done! I will look out for you this evening (your Sunday
morning) on 14.347 to see what I can hear.

We need to sort out a mode to call in, and also a way to
clearly indicate the mode being used.

Johan, in most countries there is no need to ID in any other
mode than the one in use, but with the rareness of MT-63,
most of us in the past have been identifying in Morse.

I recommend something like "de ZL1BPU MT63 xx" where
"xx" is the mode. In the past we used the name of the EVM
file, but I would recommend we quickly think up abbreviations
for the standard speeds and interleave factors.

I suggested to Nino the other day that we use "A" to mean
500 Hz, "B" for 1000 Hz, and "C" for 2000 Hz, and "0" for
short interleave and "1" for long, so for example 1 kHz long
interleave would be:

"de ZL1BPU B1"

Please let's discuss how we should best do this - your
comments are welcome. You don't have to like my
suggestion!

73,

Murray ZL1BPU

Hello Johan,

Yes that was an tricky question hi about making announcements.
We went from Psk31 to MT63, and think as soon as an CWID is built in (in the
MT63 SB windows version) , we can announce then with CWID  also the
Bandwidth (0.5, 1 or 2) and interleave short or long and perhaps something
which is not yet ready.

Cheerio now

Hello Murray, will try to be there Sunday morning, but that is always an
busy day.
Will have to try in the afternoon starting at 1200 UTC an Slowfeldhell test
with HB9JOI at 144.334.000 MHz and Hb9JOI is about 600 km away from me.
Running then about 100 watts into an 10 db antenna, so very moderate.
With our last test with FSK31, an few words were copied at the other side
and condx were normal, so not very good.
So hope Slowfeldhell will prove to work out fine, and off course we will try
an other mode next time hi.
Perhaps the V-FSK-CW mode from VK2ZTO ?

Cheeri now Murray

Nino,

A report from here using your software:

First, I had a very nice QSO with Les VK2DSG using YOUR software at 500 Hz
short interleave. Les was using the EVM.

Les could also copy me perfectly at 1 kHz long interleave, but at my end
receive was erratic - it was slow locking, and once locked, text came for
a few seconds, then rubbish, then more text. At the same time, the waterfall
stopped working, and there was no update of the status info at the bottom of
the screen,
so of course tuning was very difficult. Getting back to transmit after
receive
was also very slow and diificult to achieve.

I could not try 2 kHz, as the PC locked up. Obviously my PC is too slow,
(remember it is a 60 MHz Pentium with 20 MB memory)
as although it worked fine at 500 Hz, and transmitted at 1 kHz, it would
not receive reliably. I did try transmitting with the EVM, and confirmed
that
copy was fine, even at 2 kHz, so it was not conditions.

This evening I had a QSO with VK2DSG and 3D2AA on SSB, and we tried all the
different modes. Conditions were not good and I copied only a little of
3D2AA
at 500 Hz, although again Les and I had perfect copy. Les could not copy
Aisea either. Aisia was only RST 3x3 on SSB.

I should also report that your software does not work on Les's PC, which is
a Win98
300 MHz Pentium. Apparently the window is not completely drawn when the
program starts, the app does not achieve focus, and it hangs up with no
buttons
showing.

Still, a good start+ACE- Great stuff, and keep at it. I am sure you will have
plenty of
new improvements. CW mode and CWID would be a great asset+ACE-

Am I to presume that you will add +ACI-tuning lines+ACI- to the waterfall
display? I
wonder
about turning it off to save processor power? Maybe have a separate tuning
mode
where the waterfall runs and the decoder does not, especially for slow PCs?

I also think a tuning meter or bar graph for the Offset and Confidence would
be easier
to see while tuning in the signal.

By the way, I could not get cut and paste to wark from your UI.

73,

Murray

That's interesting... I have been playing around with it during the
weekend and Les VK2DSG and Murray ZL1BPU was using their EVM equivalent
with mixed reactions, we understand... I managed to copy Les's
transmission using 1khz with long interleave, boy isn't it fast with the
letters came up so fast on the screen.

Question is how do I know when to stop my transmission as there is no
means of monitoring.

We understand and will wait patiently for any future changes if need be.

That's the idea Aisea.

The MT63 developments at present are for DOS and Linux by SP9VRC (now
available,
but the user interface is very simple), and I suspect a user interface is
being developed by
KC7WW.

Then Nino's work for Windows 95. I believe he has some code working on
transmit and receive,
and he has promised me a beta release as soon as possible. So it looks like
Win + sound card
is not as far away as I had originally thought.

Good news, huh?

Nino,

I would like to help with the testing, but as you realise and as Johan says,
the timing
is not good for us.

Johan,

Maybe we should arrange something between ourselves, to test what you have
against my
EVM version. 0500 - 0600 UTC is a good time for me most days. Let me know
what suits
you.

Both of you,

Can you confirm which MT63 mode you have implemented there? I have three
versions
for EVM - the original 1 kHz normal interleave, and both 1 kHz and 2 kHz
double
interleave versions. From reading Nino's email, you are using what is
equivalent to the
original 1 kHz single interleave version, right? I think that is what Nino
means by short
interleave.

Also remember that Les VK2DSG is active on MT63 and is retired, so may well
be
able to take part in both Nino and Johan's testing.

73,

Murray

At 1900z I was able to copy an extremely weak signal from
you Nino
at about 40 percent copy - It was very difficult for me to
hear any
signal at all but I could see the definite sides of the
signal using gram
and my EVM   -   I was able to clearly get your callsign a
number of
times and also some of the comments re the programme and
also the
signal report that you sent -  409  -  I also done a copy
and paste of your
recieved test and sent it back to you - I wonder if you were
able to
recieve it at all

Murry - Aisea and myself have been doing some tests as you
will have
been able to see from previous emails

At this point in time I am unable to run your programme as
it locks up on loading
with just an inactive screen appearing or it will load the
prog and I will have
the date square on it and when i cancel this the whole prog
will disappear

I can hear some more mt63 on the radio so I will hae a

Hello MT63-friends,

yesterday achieved my first MT63-DX, have worked VK2DSG
over about 17,000 Km+ACE- It's remarkable to see how it is
a very sensitive mode (signal was barely audible), in
my opinion comparable to PSK31 (yes, I agree we need numbers+ACE-).

What is interesting, is that if one writes in lowercase and
there are errors in the data bits, you often see the
correct letter but in uppercase+ACE- Is that the power of
the Walsh function? (Pawel if listening enlight us...)


Murray wrote:

+AD4-
+AD4- Les could also copy me perfectly at

+AD4-

we have noticed that Les' audio signal is
cut out just below 1 Khz (maybe a filter
in the RTX), that's probably why the copy
was not so good. And this shows how this
mode is robust... you can make QSO even
with half the signal+ACE-

Now about the soundcard program:
I've added a dedicated page on my website
at http://ninopo.freeweb.org where I will
release the program when ready. BTW, online
is a newer beta wich does not have the date
bug but is more CPU intensive (sorry Murray)
as it tries to decode the outgoing signal too.
Ah, there is a cool +ACI-alarm+ACI- function if you
want to monitor the qrg leaving the RTX volume
to zero.

PSE note: at this stage of the project please
use all beta releases with care as I cant ensure

anything about them :-)


See you with other good news,

Nino IZ8BLY

Hi Nino

You will be happy to know that I have located and fixed the
problem
with the tx on mt63 - it turned out to be the way the menu
items
were set for using rtty - I have now changed all the
settings so that
  I can see a full tx pattern
the problems appear to be the settings for the 920 in menu
numbers
U-42  - rtty tone settings - now set to lo1275u
U43  -  rtty shift setting - now set to wide shift
U46 - alignment of the txrx tone pair
Anyway - the resetting of these paras has fixed the proloem

+AD4- Hello MT63-friends,
+AD4-
+AD4- yesterday achieved my first MT63-DX, have worked VK2DSG
+AD4- over about 17,000 Km+ACE- It's remarkable to see how it is
+AD4- a very sensitive mode (signal was barely audible), in
+AD4- my opinion comparable to PSK31 (yes, I agree we need
numbers+ACE-).
+AD4-
+AD4- What is interesting, is that if one writes in lowercase
and
+AD4- there are errors in the data bits, you often see the
+AD4- correct letter but in uppercase+ACE- Is that the power of
+AD4- the Walsh function? (Pawel if listening enlight us...)

+AD4- we have noticed that Les' audio signal is
+AD4- cut out just below 1 Khz (maybe a filter
+AD4- in the RTX), that's probably why the copy
+AD4- was not so good. And this shows how this
+AD4- mode is robust... you can make QSO even
+AD4- with half the signal+ACE-

+AD4- Now about the soundcard program:
+AD4- I've added a dedicated page on my website
+AD4- at http://ninopo.freeweb.org where I will
+AD4- release the program when ready. BTW, online
+AD4- is a newer beta wich does not have the date
+AD4- bug but is more CPU intensive (sorry Murray)
+AD4- as it tries to decode the outgoing signal too.
+AD4- Ah, there is a cool +ACI-alarm+ACI- function if you
+AD4- want to monitor the qrg leaving the RTX volume
+AD4- to zero.
+AD4-
+AD4- PSE note: at this stage of the project please
+AD4- use all beta releases with care as I cant ensure
+AD4-
+AD4- anything about them :-)

Hi all:

I unfortunately have not been home when the testing has been done, so I don't
yet have
any QSO's with Nino's new software.  I did decide to do a test with his program
and my
EVM (using a tape recorder), with the following results:

Using Nino's program, and the most recent MT63 code (from Murrays site), I have
found
the following settings appear to maintain compatibility between the two devices:

500  Hz on EVM:   Use 500  "short interleave" on IZ8BLY program
1000Hz on EVM:   Use 1000 "long interleave"
2000Hz on EVM:   Use 2000 "long interleave"

I don't know if this was addressed before, but if not, I feel we should try to
keep
using the above settings so we can communicate with others who use the EVM
programs.

I also noticed a couple of random  program errors while doing the tests, but
have not
been able to duplicate them.  If they recur, I will post them.

Nino:  Keep up the great work!!

Nino,

I know your new MT63 version has more processing, so is more intensive.

I wonder - a few suggestions that might make it work better on slow
computers:

1. Allow full duplex to be disabled.
2. Allow the waterfall to be disabled, or perhaps have a +ACI-tune+ACI- mode
where the waterfall works, but the decoder does not, and a +ACI-receive+ACI-
mode where the opposite is true.
3. Have a tuning meter that uses the status information from the MT63
engine.


I also think it might be useful to have a +ACI-confidence+ACI- meter. I think
the
waterfall needs a cursor at 500 Hz, and possibly another at 1 kHz. I am
sure one will be enough.

Morse ID on the lower edge (say at 490 Hz) would be a great idea, as
it would make identifying the mode and sidband easy.

New country on Feld-Hell+ACE- Have made 28 countries finally, by working
Emmanuel SV1COD. Very nice QSO too. I need to be more active+ACE-

Murray

Folks,

I am in the process of updating the MT63 Web site at
http://www.qsl.net/zl1bpu/MT63/MT63.html.

I realise what is there at present is out of date and inadequate,
so if there is something you specifically would like to see,
please let me know.

I plan to host the software for EVM, Linux and Windows. I have
already written much of the upgrade, and it should be uploaded
before the weekend.

This is your show - if you want something out there, let me know!

73,

Murray ZL1BPU

Hello,

What is the latest "official" version of the MT63 EVM code?
The most recent mt63asc.asm I have is dated 20-DEC-98 in the
comments at the top.  There seem to be a few .CLD files floating
around, but I cannot tell if they have any fundamental changes
to the code, or simply different assembly-time options set.

Thanks,

Doug Braun
