Hi guys,

I've installed it on two laptops and got them talking across the room.
Anybody is willing to play "real" in near future??

Best may be 20 m and US early evening.

BTW the condx are very good right now.

He had the trifecta:

1) sidebars around his main signal

2) second and third harmonic of his audio frequency
visible on the waterfall (600, 1200 & 1800 Hz)

3) drifting just enough during and between transmissions
for fldigi to lose track trying to copy his signal

The only thing missing were background noises from his
shack.

And hamcom modem is cheap

Just an opamp powerd from the rs232 .. Used as komparator

So you need no soundcard ...

What about using an si570 for the vfo?

And there is a lcd circuit for controlling the si570 .

That would give a nice cw psk rtty trx

I know that the old hamcom software does this .

In rtty and cw mode is sends the data 1:1 out on a serial pin on the rs 232

I know this exactly as I made a mod in my hamcom modem.

In rx the transistor is always set to high so I had to connect the ptt
transistor and the fsk transistor in series

(connector of one going to emitter of the other .

I cutted the ground connection of the fsk transistor and connected that to
the collector of the ptt transistor

So with that soft you surely can do this

The soft runs well in a dosbox (as I know)

You wanna go cheap?

Take an old laptop with win98 on it

A slow one will work okay with it and on the older ones you will have a

Try PSK31 or contestia to contact VK. I think it is not so much the mode
(since how can that be?) but the contact you made that made you favor ROS.

I like experimenting and it is a new toy … thats why i favor it .. and I
wrote that I worked vk and zl with the mode 

And I had no luck with other modes for such a big distance…

MORE ROS USERS … but you surely know that

 


More Pactor, Packet and WINMOR users??? Since that is what I am saying with
my "SSTV argument": a growing number of users implies more patience by ROS
users, and a better timing when to call CQ for those users. It does NOT
imply more calling frequencies. No other mode "claims" three calling
frequencies on one band.

A third??? Needed??? More patience and better operating practice is needed
for ROS users.

As it is needed for all hams in a pileup … agree with that … stay cool and
wait till you et the qso … if not try next day

Better not make QSO's at all in a wideband digi section were "unattended"
servers reside

It is digital and it is wideband …. And can be used as beacon … so wherelse
as in the digital area should ros go??

Jose changed the qrg several times … and asked on the hp for qrg to put it
in the soft … okay maybe 1 qrg would be easier to find than 3 of them …. 

. It is asking for QRM since often "automatic forwarding" takes place on
these frequencies. The frequencies are crowded there already so why try to
fit in with a 2200Hz wide mode? Better try to find an "own" watering hole
for ROS SINCE it is that wide.

It would be like using ROS on the SSTV frequency. But since that is a KNOWN
frequency for SSTV, people do not use 14.230 for any other mode. So why not
apply the same logic on 14.103/14.112/14.115 since all these frequencies are
used almost non stop by billboard systems and alike.

 

ALL USED BY BBS ??? how many qrgs for the bbs??? the whole area???

> Marc you said only one qrg on 20 for sstv??? I see traffic on 14230 as

Digital SSTV is a completely different mode. Just listen to them and you
will know/hear the big difference. The only resemblance between the two is
sending pics. So the two modes SHARE the frequency.



As i know 240 is digital … and the other analog so no sharing

 

And on 14.227 and 14.233 there are no other modes operating on fixed
frequencies like packet/pactor BBS do on 14.103, 14.112 and 14.115, that is
a big difference.

If and ONLY if that frequency is free. And most of the times 14.233 or
14.227 are free. There is rarely SSTV traffic beyond these frequencies
except in August during the JASTA contest. Then the "SSTV gang" as you call
them, use 14.230 +/- 3Kc/6Kc. But even then during contest most traffic is
still on 14.230

So maybe 14.236 would have been a good frequency for ROS, since it is rarely
used since it is so close to the SSTV and digital SSTV center of activity
and can easily be SHARED with these modes.

I hear the ssty guys crying : marc why you said the ros guys to move on OUR
qrg???



The calling frequencieS for ROS are most of the time in use, and have been
in use for years for many pactor servers or packet BBS. So it was quite
incosiderate by José and the ROS users to choose these frequencieS. That is
again a big difference.

Tell jose better qrg … he changed it several times and the digital area is
not so very wide …

Can we move outside the digital area … I think not as we have to stay in the
digital area written down in the bandplans

Moving completely out of digital is not okay I think … but others maybe know
it better

[Siegfried Jackstien]

Marc . i agree that jose is as dummy . if you see his behaviour in some
situations

I do not wanna defend him (AS I DO NOT LIKE HIDDEN FUNCTIONS TOO)

I just like the new mode as it works so well

I just like experimenting with new "toys"

That's all

Sure it would be way easier if he had a lis and if he knew better how to
invoke new stuff to the crowd

I often asked him about some things that could be made better . but he has
his own thoughts

Some things in the soft came from my ideas (example distance calculation)

It was ME that sent several dozen mails to users that I have seen in the
cluster . just to tell them to shut the autospot off

Days before it was ME that wrote how to stop the spotting with a firewall
(in versions before there was no switch)

Just to make pressure on jose to make that switch available .

So I have some same thoughts as you and some are different

If I see a pactor station in waterfall I do qsy . others may think ros does
it even if there is some other mode on the qrg and send ontop of the pactor
station but that's the fault of the user .. not of the developer 

I just hope that after some time ALL users shut off the spotting

Just because I do not want that more and more cluster sysops block ros-spots

Sending ontop other stations is not okay . agree 100x100

Jose made 3 qrg on 20m band to give more users a chance .

As this mode goes "around the blue marble" with a few watts he programmed
the 3 qrg on 20m

Now we have only a few hundred users (yet) so when there are a few thousands
the 3 qrg are "a must" I think

Time will show it ...

I see only low traffic on 115 most is on 103 and 112 so time will show if
the third is needed

If I look in the bandplan I see that automatic stations is upper limit 112
so maybe we shoud use the lower qrg for (low power)beaconing with ros and
only 115 for keyboard to keyboard qsos

 

Marc you said only one qrg on 20 for sstv??? I see traffic on 14230 as
centre of activity . but also on 233, 236, 240(digi)

Same story but other mode ... most traffic is on 230 in sstv .. As it is on
103 for ros

And if there is more users on air or other modes using 103 I (and others)
qsy to 112 and 115

Like the sstv gang is doing . traffic on 230 . move to 233 or 236

 

>changing one's motives and mindset is a completely different matter...



Right and well said Marc .. Not easy to change joses mind in some cases ..

Sometimes friendly asking helps . sometimes you have to give him a kick in
his back hi hi (see the sent mails by me as such a kick)

 

I do not know him very well . just had some emails with him and I also do
not like all he does .

But now we have to live with what we have . just make it wise .

Wait if there are other stations ... stay cool .

I can wait if there is other traffic . as I know I can work the world with
this mode there is no time pressure for me

I worked vk4 with a few watts and so there is no next goal for me (so I
often only monitor now)

But others are new and so they are experimenting like I did in the first
weeks

[Siegfried Jackstien]

it's hard coded banned calls list, it's three calling frequencies on 20m,
it's inferior [to contestia] wide band mode, it's auto spotting on DX
clusters).

 

"hall of shame" does not exist anymore (as I know)

 

3 qrg on 20 . yes it is the most used dx band .. How many phone channels of
3khz ???

You argue about the bandwith . as wide as a phone conversation so what?

Would you also tell the same to any phone operator?!? Hey your voice is 3kc
wide . could you please use cw or psk???

It is another experimental mode . time will show if it is longer used or not
(like many other modes)

 

Autospotfunction can now be switched off by the user so we all can switch it
off

No autospots > no more sysops of clusters will ban the mode

 

Okay joses behaviour in bringing the mode further is not okay . but he made
a great software

So why not use what we have?!?

 

In the newest version he made a autoreport to pskreporter map

As we can see the traffic now on a map we do not need the autospot anymore

So hopefully all users will upgrade their soft and switch the spotting off

A gun can be a weapon to kill . or just a sport gun .. for precisely making

So it depends on for what you use that gun

I like the sportive way .

See how far I can go with a few watts on a simple antenna

But others might use it for :how many winmore stations can I make angry .

So you see it depends on the users .. .and what are the users .. WE ARE

>A safety pin on a gun, doesn't make the gun less destructive Sigi...

 

Right but prevents loosing a shot by accident while the gun is in your
pocket

There are still users that do not know what is the soft doing in the
background as not all users read the news (this group and others)

 

If every user switches the function off it is like jose never programmed it

He uses the same triggers for the psk reporter page (map view)

So why not just switch spots off and enjoy the nice view on the map

We can use the programmed (hardcoded) clusters for sending INTERRESTING
spots by hand

So just use what we have with the needed options

I do not like that joses soft is spamming the clusters

As some sysops do not forward ros spots anymore jose has to change them in
every new version

If spots were set to off nobody would be angry about some hand spotted calls

The massive flooding (about 20 + spot per hour) is the problem

So the safety pin is fine 

But in a new installed version the pin is set to "unsafe"

Glad i could help

 

Iif you do NOT use cat the autogenerated spots on 20m are sent as 14000 . so
not correct

But when sending by hand qrg is correct

I asked jose if he can solve that . that a user without can do not send
wrong qrg . maybe he will find a solution for that

As we have now the autoreport to pskreporter we do not need the autospots
anymore (but jose thinks it is still needed)

So every user should switch that off and spot only by hand

Iin the tab skets click on cluster

There you can send spots manually and switch off the autospotting

I let the newest version run for a few hours >>> not autospots were sent
when switch was off

You can send autogenerated and in downloaded newest version the switch is
set normally to on . so as the users do not switch it off (or using old
version) there is the reason for the soft still sending spots

So all users should manually switch that function off ! ! !

Psk reporter sends to the map

Cluster sends to telnet

Ros sends on air and the emails via gmail

AW: AW: [digitalradio] Operating ROS In USA

[Siegfried Jackstien]

They would say  . you know the rules and you have to follow the rules

The thing is . who has to make the technical decision if ros is spread
spectrum so forbidden in us (answer: the user)

Next thing is . is ros really ss??? What I know about ss is sender and
receiver are spreading the data very wide

Factor 10 is minimum to say it is ss but normally far more is used

In ros the spreading factor is very small . and so it looks more like mfsk
on the air

For me as I am no professional in data transmissions it looks like it is
afsk (like many other soundcard modes)

Does the ham need to have the knowledge how the tones are calculated???

If the tones are spread spectrum or not??

What about digital sstv modes?? How can a user know if the used bandwith is
(much) more as needed??

Any fec mode uses more bw or more time as needed for a non fec transmission

 

Why not just modify the rules a bit

Frequency hopping or wide spread spectrum only above 220

And the narrowband ss modes like ros and all other modes (incl. chip, Olivia
and similar) can be used on shortwave if the bw is lower as 3kc (like her in
dl)...surely with sdr wider ss modes could be used . but not allowed

Synced frequency hopping with sdr would also be possible . but not allowed

Just say . any mode bw <3kc ..(exceptions possible like >0.5kc on 30m or
historical am transmissions)

That would be easy

 

All modes should be free available to anybody (so fcc cia mi6 etc can
download the soft and use it too)

 

Modes where you need special hardware are only allowed if the developer also
gives a free software solution (for receive only) 

(hello d-star, hello scs) ..for monitoring

 

Think about > changing your rules is easier as trying to tel ros is not ss
.. Cause next new mode will come soon . and story returns . so change your
laws in us

Here in germany we have the same with "sonderkanal s6" . tone is near qrg of
some 2m repeaters on 145.750

AW: [digitalradio] New question

[Siegfried Jackstien]

Okay now for all users to read and notice

First of all @jose : no I am not crazy, but all users should know what your
soft does EXACTLY>>>

 

For the rest of the world:

There are 2 exe in the ros folder

Ros(versxyz).exe is doing the on air things and the emailreport

Adifdata.exe is connecting to different clusters and sends the (wrong) spots

 

Jose decided to spread the users over the qrgs as he is doing it with his
tones in the channel

 If the spots were correct there would be a pileup every day and no user
could do a qso he thinks

 

So what he did is

Ros sends the data to adifdata via ros ini

So far so good

But the qrg is randomly calculated . so almost never correct . in the
autogenerated spots you only see who is working but not where (qrg)

The only way to get rid of the wrong spots is to denie the adifdata to
connect to the cluster

As vk3ama has closed the spotpage there is no need to send those false spots
anymore

So we users (I am a fan of that mode) can only get jose to change if we do
not sent those false spots

Many syops around the world put ROS on the bad word list cause of the
massive spotflooding and that the spots are false

Only Solution is:

Take a firewall and block the adifdata

Spot only real qso by hand typing (avoid the bad word to get a better chance
of forwarding)

Emailfunction can be used or not . has been safe so far . but who knows what
comes next

If jose change the randomizing of qrg and let the user decide whether to
send a spot or not I will use the spotfunction again

Then after change you know who is on air and where to find (that is all
needed info)

Till he changed his mind we ALL should block the autospotfunction cause it
is making more trouble as it helps

 

So please give that info to all other ros user

 

Maybe we can get rid of that bad behaviour (of the soft and his builder)

 

JOSE IT IS TIME TO CHANGE ! !

 

Best would be no autospotting at all

 

I decide to use ros without it and hope all others do the same

 

If no spots get in the cluster the function is useless

All ros spots are bogus . or almost all ... most of them wrong

@rein you should keep the old 1.0 cause that is the last one with a
blockable adifdata exe

All versions after the first 1.0 (the new 1.0, 470beta and 471 beta) close
after a while if adifdata can get no inet

So if you wanna use that soft WITHOUT sending spots you should keep the old
1.0

No . just block adif exe in a firewall and everything is fine

You can use the soft with or without email but without spotting is only
possible when using a firewall

The soft does not spot later . think you have no inet at home today.
tomorrow you get inet . if now the soft would spot later there were hundreds
of spots (of no need cause from yesterday) so the soft sends right on time
(or is quiet)

bring jose to think

But if he has made a decision there is almost no way to change his thoughts

I do not know if boycott will help . but stopping adif is boycott on the
spots . 

 

 

AW: [digitalradio] Re: Moving ROS forward in the USA?

[Siegfried Jackstien]

That would mean if you would implement ros or similar in a multimode soft
like multipsk or dm780 you would not be allowed to use it (the whole soft)
in us ??? I think if only a part of the soft is forbidden to use (on
transmit) all other modes can be used

If for instance rtty was forbidden in germany but no other mode I can use
all other modes in a given software

So if in us ros hf is forbidden (but not ros mf) you could use it in us .
right??

Just my understanding of laws ,, but I may be wrong

AW: [digitalradio] ROS Developer will continue to auto-spot despite complaints

[Siegfried Jackstien]

Just added adif exe to my firewall

No data in no data out

Can use ros now as I have no inet access

Jose does monitor eu traffic via twente . so does the soft send (hidden)
data on the air??? I do not know . but I do not matter about cause I have
absolutely no passwords (except the gmail password used in ros) on my pc . I
do no internet banking so nothing to hide on my pc

Even if the software has a Trojan in it that allows jose to spy on my pc I
would no matter about it cause my pc is clean in any way (nothing to hide)

No cracked software, no stolen mp3 music, nothing but ham-software (99.8%
freeware)

 

Jose made that function only to give ros a kick .. That kick got in his face
(or his back)

So it is time for him to work around that function . user setable, can be
switched off, correct data, no fake qsos .. Should be easy done from him if
he is willing to do

But the comments on his hp shows that he is not willing to switch it off ...
maybe he can work around that the spots are correct

No random texts like there was a qso if there was none etc.

As we all know jose reads all the boards . so:

 

J O S E . I REALLY LIKE THAT MODE BUT CAN YOU PLEASE PAY ATTENTION WHAT THE
USER NEEDS ?!?

 

To get the mode more popular instead of being more and more hated Jose
REALLY should think about all that 

 

I know that otherwise your betatesters will no longer use your software

 

PLEASE (begging on my knees) JOSE DO NOT KILL YOUR SOFT BY YOURSELF

 

As this was the first (for me) to get a 16000km qso I would like that mode
not to be killed

 

Hopefully Jose takes some time (after a cup of tea) stays cool and thinks
about what we need and what we do not need

It is time for jose to think the autospotting over

In the stating of ros it was to make it more popular (tell others that ros
is there and alive)

But now as there are more and more users we do need no autospotting . we
need a spotfunction that work like the user needs them

Only spots of real qsos with no precoded messages but user settable text
(s/n , distance etc. included)

That would be way better

And no hard coded clusters .. Better you can log on you "home-cluster" . so
also user settable

AW: [digitalradio] Re: my thoughts about ROS (was Ros on 40m)

[Siegfried Jackstien]

Agree on that ,,, ros is wide band and there is not enough room for all ..
It is for long distance not for italy spain or similar

And about the bandwith used: jose is working on the soft to make more than
just one conversation on a given channel possible

But that is not done yet so for the first tests we have to live with what we
have (or make suggestions by mail or in the group)

Ros is not ready ,,, it is beta and it will be till most work is done.

For me it was first digitsl contact with vk land . I have no beam and no pa
. so for me it is the right mode for vk or zl

I just monitor most of the time and if I see a nice long distance call I try
my luck

Other use the software for uk italy or spain france etc . that is not the
right way

For that short hops psk is much better

(multichannel decoding in panoramic view and lower used bandwith etc,)

But for stations that have only low power and a low gain antenna ros can be
very good to get that last missing land

And as everybody knows ros is brand new . do you remember when new things
were invented ?

There were everytime people against new things ..

>For what purpose?  If he's not a ham, then it isn't to support the amateur
community.  However, I can think of a lot of uses for a low-power system
using a low->profile antenna that is designed to work under the noise floor;
especially useful for military, government, and even some more sinister
uses. 

 

Surely jose is a sleeper making software for  BIN L. or other terror
organisation :-)

>So his hobby is programming … he gives us a great soft for free and we
should take that chance

>I think that a lot of people have a hard time with some of Jose's actions,
such as hard-coding QRGs into the software, and hard-coding a
persona-non-grata listing >(in which I am included) of hams that are
forbidden from using the software simply for criticizing some aspect of it.



The qrg is hard coded for the cat control but you can turn your vfo by hand
, can´t you? …. The mode is used on that qrgs that are in the soft. If more
and more users use ros on the air we have a different situation …. Maybe we
need not only 1 qrg per band (except 20m) but a used area on the bands with
a (center of activity) as call channel


>Since Jose isn't doing all of this work just for amateur radio, and since
he isn't willing to accept criticism and suggestions from the amateur
community, it is natural >to question the ultimate purpose of the software.
Until Jose comes clean, opens up the software to all amateurs (including
those on the persona-non-grata list), and >graciously accepts both
suggestions and criticism, many people will continue to campaign strongly
against the mode.  



I do not know what you and the others in the hall of shame did that made
jose angry

He accepts suggestions (I asked for a function and a few versions later the
function was there)

Has anybody in this blacklist ever read the read me text ??? there are
SEVERAL functions that jose implemented after suggestions of users

And I do not see any military or government organisation that uses locator
with distance and bearing calculating and auto emailreports etc.

So that must be a software for hamradio operators (in this moment not for
all of them)

 

Until he comes clean?!? Do you think he takes drugs or too much alcohol??
Surely he could not do such a work with that

No that is not correct …

Does wspr send keyboard to keyboard with any text at any given time with 300
signs a minute ?

No wspr is different in many ways

Wspr is okay for propagation tests with low power and has a fixed transmit
window (in time)

Ros is faster, has no timing window and no precoded messages

so you can type what you want to the other … not only call locator and
output

any text is possible

faster as most of us can type

 

 

 

 

AW: [digitalradio] Re: ROS on 40 meters

[Siegfried Jackstien]

*   exactly every minute

 

so the other stations must have made their beacontext with a stopwatch

 

if you send the beacon in ros to 1 minute the soft DOES NOT transmit exactly
every minute for more than just one reason:

first of all the duration of the beacontext is added to the timer cause
timer restarts AFTER sending . that is why I said the stopwatch thing

okay say duration of text is 15 sec so you set beacon to 45 sec . does now
the soft send every minute?

NO NO NO

The second thing is that jose made another timer with 150 sec in the soft
THAT CAN NOT BE MADE SHORTER BY THE USER

And that timer is resetted if there is traffic . so the beacon does only
work if there is NO TRAFFIC

Beacon does not send if others use that qrg (in mode ros)

 

AW: [digitalradio] Re: ROS on 40 meters

[Siegfried Jackstien]

>Mercedes has a speed limiter for fun I presume...

No the limiter is for safety . but with a laptop and the right software the
limiter is away (and you also get some more power)

 

Okay jose should implement an rf sniffer in the software . if you switch on
you pa the audio is turned down automatic

If you transmit more than 3 times with too much output the soft sends an
email to fcc (or other local regulation agency) ... kidding of

 

 

AW: [digitalradio] Re: ROS on 40 meters

[Siegfried Jackstien]

The qrm is NOT from beacon function in the soft

I see you do not know his software

If the qrg is in use (of other ros transmissions) the beacontimer is
resetted and no beacon is sent

[digitalradio] my thoughts about ROS (was Ros on 40m)

[Siegfried Jackstien]

These are my personal thoughts about ROS and some info about what Jose told
me about his interests / his goals

Other may think different or have other info

 

Please do not be angry about me or about Jose!!

 

My thought is also that it would give less problems with the soft if jose
were a ham

but sadly he is not . in an email conversation with him he explained to me
what his interests are : 

 

Not exchanging callsigns or macros .. nor 5by9 the next one please .

without reading the signal meter and with several askings after the call 

or name some people give that report .. is that okay? 

I think not!!

The software give a measured signal report . if you want you can get
automatic reports by mail etc 

so for propagation tests or antenna tests that software sends no 5by9 report
. it gives you real numbers

that is a much better report I think

 

His interest is making a software that gets over the ocean under the
noiselevel with a few watts and a simple antenna !

 

And my personal on air test showed that he finally did it

 

I had several contacts over 8000 + + + km long paths with only a few watts
on my dipole in the night with a closed band

No psk signals on the waterfall .. nothing on the air but noise .. Go to a
ros qrg and wait

You will be surprised what you see on your screen

 

YES I Am A FAN OF THAT SOFT (you surely thought that before I wrote it down
here)

My record is 16000 km on 20 and 40m with this setup

This software need a full ssb channel 3kc wide .. .as every phone or sstv
contact does

So it is taking nothing more on bandwith as other modes do .. Yes it is a
ton wider as psk 31

But with psk you surely could not do what can be done with ROS 

 

I think that the soft is good for making qrpp test or other things were you
have only low output

The mf folks and the eme guys for instance . so surely if he were a ham
things would be easier

There were the myths circulating that if the soft is ready jose will make it
commercial

But he said it will not be commercial

sure that his interests are the one above . his hobby is programming

I follow the soft since February this year . on some days he uploaded 2 or 3
versions

In the weekdays most of the time a version a day and on weekends sometimes
more than a version

So he does nothing more than sitting at the pc and programming

I asked him several times if he has no family no friends and if he is ever
sleeping

cause he spends LOTS of time with making the soft better

If we are interested in a long distance mode (I am!) we should help him to
make it better (even if he is no ham)

As he did not know the packet and pactor nets and who is on what qrg he
looked in the bandplans and so were the qrg settings 

He did not know it better so we should inform him what we need ..

I asked him for a distance calculator and in the next version it was there

 

So his hobby is programming . he gives us a great soft for free and we
should take that chance

 

Have a nice day

AW: [digitalradio] Re: ROS on 40 meters

[Siegfried Jackstien]

As most dx is done on 20m and to give more hams a chance for a qso jose made
3 qrg on 20m . and he changed them SEVERAL TIMES after there were some other
telling there is a pactor qrg or this is a packet qrg etc. .. he asked
several times about qrg so I do not see where you have a problem . yes it is
a wide mode but it is used for LONG DISTANCE DX with low power .. From italy
to spain with a beam and a gallon of output you can do it with voice, psk,
or something else .

Ros is programmed for low power qrppp experiments . with a few watt and a
groundplane for a 16000 km path .. But there are users thinking more power
is better . and using ros the wrong way ..  With lots of power and a beam .
so to give others a better chance there are 3 qrg on 20m . that's all

Sometimes I hear packet or pactor on one or two of the 20m qrg so if I hear
that I go to the third qrg and try it there .

AW: [digitalradio] Re: Individual software programs for various digital modes????

[Siegfried Jackstien]

What about multipsk?!? Has as many modes as needed (and lots more) so you
need not to change soft when changing mode..

And there is a logbook too (or better say a free available soft that can be
used with it)

Can control trx via commander (but that is not a must)

Can be used together with dxkeeper(but also not must be used together with)

Has almost the same panoramic view as the superbrowser in hrd to receive
many stations simultaneous

What I like with the soft is the mapview:

Let the panoramic run for a while with opened map and see where conditions
are

Received countrys are spotted as a black dot in the country and received
locators exatly where they are on the map with red dots.

Very nice to let it run and see if there is a new country ..

So for the most modes I use multipsk ..

As it is free for download you should test it ..

Some functions are limited in the free version but for trying them out that
is no problem . if you like it just send Patrick the 30 buck .

But you can use almost all functions in the free version so just try it out

I didn't realize you could use DM780 on its own. I have always found HRD way
too complicated, and I don't need a screen full of radio controls taking up
useful space when the radio's front panel is right next to me.

The disadvantage of using different programs instead of standardizing on one
is that you lose the benefits of computer logging. I guess the OP maintains
a paper log so he isn't concerned with that aspect.

Does DM780 have a log, or do you need HRD for that?

All  in 4, 8 or 16 baud with bandwith of 2250hz and center of 1500hz except
30m were only 500hz bandwith is allowed

On 2m there is 144.160 used for eme tests with bandwith of 64hz .. but that
something different than that what you heard on 7056

More info (and the software) can be found here :

If one of the qrg´s in the list above are making qrm (maybe on a packet net

Betreff: [digitalradio] Digital Suite Performance

 

  

While training for the Buffalo Marathon, I have been pondering (while on
some LONG runs) which of the popular digital software (for Windows) offers
the most performance. By that, I mean, best and most capable under the
conditions, and not number of modes offered. By THAT comparison, MultiPSK
would win handily, and there would be no need for any more discussion.
However, having a QRP-only station forces me to try different suites for
different reasons.

Which software do YOU the members use? Which ones are better at weak-signal
levels? Best "ALL AROUND" performer?

I started wondering this recently as I downloaded the "Weak Olivia" wav file
off of this group's FILES section. And MultiPSK could copy most of it, while
fldigi could copy more than 99% of it with very few misses or errors. I
haven't tried this experiment with DM780 yet...or MixW for that matter.

Although I prefer the eye-candy/beauty of DM780, I still can't get away from
MultiPSK and its usefulness...especially with ALE400, Pactor, or basic QRSS.

AW: [digitalradio] ROS carrier pattern when idle

[Siegfried Jackstien]

Just as an idea:

Ad a (non-random) idle to the soft ROS maybe with a bit higher audio level
selectable by the user

Can be used to resync, for afc, etc.

So decoding maybe a bit better 

And you have overcome the SS problem (if it is a problem . but I do not see
any)

During sending data the randomize is to become better decoding while there
is qrm

so it is just a question of definition I think

dg9bfc

 

ps all modes should be allowed anywhere if bw is <3kc (or <500hz in some
bands/areas)

so no ss over the whole band or across many bands like a plc modem

but ss in a given channel of a ssb-filter

hamradio is an experimental hobby!

Alan,

Of course, the FCC rules on SS are outdated and ROS should be allowed due to
its narrow spreading range, but the road to success is not to just rename a
spread spectrum modem to something else and try to fool the FCC. This is a
sure way to lose the battle. The genie is already out of the bottle!

Instead, just petition the FCC for a waiver, or amendment, to the
regulations that are a problem, to allow FHSS as long as the spreading does
not exceed 3000 Hz and the signal is capable of being monitored by third
parties. Do this, and there is not a problem anymore. But, do not try to
disguise the fact that FHSS is being used by calling it something else, as
that undermines the credibilty of the author of the mode and will make the
FCC even more determined not to it on HF/VHF.

It looks to me that the tone frequencies are clearly being generated
independently from the data and then the data applied to the randomly
generated frequency. There is NO pattern to ROS like there is to FSK modes,
even to 32 tone FSK (Olivia 32-1000) or to 64 tone FSK (MT63-2000). This is
a signature of FHSS.

"If it walks like a duck, quacks like a duck, looks like a duck, it must be
a duck". 

It looks like ROS really is FHSS when you look at it on a spectrum analyzer,
and the spectrum analyzer does not lie.

It's pretty common in modems to randomize the data to prevent carriers
when sending all zero's or ones. Phone modems do it, I'm pretty sure P3
does, and other RF modems do.

I know of another amateur RF modem that had randomized spectra by
design. By this test it would have been considered spreadspectrum, but
it was not, it was mfsk with a randomizer. The randomizing algorithm was
provided to the FCC, and life was good. This was before SS was allowed
at all, and there was not a bit of discussion that it might have been
spread-spectrum.

If MFSK16 was randomized would it magically become spread-spectrum?

All I know is, this is not the spread spectrum everyone is worried is
going to ruin the bands! IE: traditional spread spectrum with bandwidth
expansion of 100-1000.

At a given time if you make a snapshot there is only one tone so bw at a

Betreff: [digitalradio] The FCC's definition of Spread Spectrum

 

  


Part 97.3 "Definitions" defines: "SS. Spread-spectrum emissions using
bandwidth-expansion modulation emissions having designators with A, C, D, F,
G, H, J or R as the first symbol; X as the second symbol; X as the third
symbol. "

Title 47 Sec. 2.201 is the relevant section formally defining these symbols.
It can be found on the ARRL website.

For a signal to be officially considered Spread Spectrum by the FCC, it
would have to meet a very specific description, or maybe I should say it
should not meet the other specific definitions of emissions.

After my reading of 2.201, I don't think that ROS or Chip64 could be
"officially" defined as Spread Spectrum.

And, the response from the FCC doesn't provide any FCC position or
interpretation of ROS, and further says "The Commission does not determine
if a particular mode "truly" represents spread spectrum as it is defined in
the rules."

Just my thoughts,

Hi Jose,

Of course we start that way (using a SSB filter), but then a Pactor station
will come on, cover the upper fourth of the ROS signal, and decoding becomes
garbage until it leaves. With a more narrow mode, the Pactor station can
just be filtered out at IF frequencies and not affect either the AGC or the
decoding of something like MFSK16 or Olivia 16-500, as long as those signals
are sufficiently away from the Pactor signal (even if they are still within
the bandwidth of a ROS signal).

In the case of CW stations, during the contest, they just appeared in the
SSB filter bandwidth, and therefore among the ROS tones, and some of those
also stopped decoding until they left.

Let's say a MT63-500 signal appears at 2000 Hz tone frequency (i.e. covering
from 2000 to 2500 Hz) at the same signal strength as the ROS signal. Will
ROS stop decoding? If a MT-63-1000 signal appears at 1500 Hz tone frequency,
will ROS stop decoding? If this happens and there is a more narrowband
signal like MFSK16, for instance, covering from 500 Hz to 1000 Hz, the
MFSK16 signal can coexist with the MT63 signal unless the MT63 signal has
captured the AGC and cutting the gain. If it has, then passband tuning can
cut out the MT63 signal, leaving only the MFSK16 signal undisturbed and
decoding. In other words, there is less chance for an interfering signal to
partially or completely cover a more narrow signal that there is a much
wider one, unless the wider one can still decode with half or 25% of its
tones covered up. The question posed is how well ROS can handle QRM, and
that is what I tried to see.

If ROS can withstand half of its bandwidth covered with an interfering
signal and still decode properly then I cannot explain what I saw, but
decoding definitely stopped or changed to garbage when the Pactor signal
came on.

Howard,

After monitoring 14.101 continuously for two days, I find the following:

1. CW signals (of narrow width, of course) during this past weekend contest
often disrupted decoding, and it looks like it was not desensitization due
to AGC capture, as the  ROS signals on the waterfall did not appear any
weaker.

2. Pactor signals of 500 Hz width, outside the ROS signal, that capture the
AGC, do desensitize the receiver and cause loss of decoding, as expected.
Passband tuning takes care of that problem however.

3. Pactor signals which have the same degree of darkness as the ROS
carriers, and occur within the upper third of the ROS signal, cause loss of
decoding, and it is not possible to fix the problem with passband tuning, as
trying to do that appears to take away enough of the ROS signal that the
degree of frequency hopping used is insufficient to overcome. Receiver is
the IC-746Pro.

4. If more than one ROS signal is present on the frequency, ROS will decode
one of them - apparently the strongest one - and the weaker one is blanked
out until the stronger one goes away and the the weaker one is decoded.

5. Compared to Olivia 16-500, for example, the width of the ROS signal seems
to be a disadvantage as far as handling QRM is concerned. Five Olivia 16-500
signals will fit in the same space as one ROS signal needs, so QRM, covering
the top 40% of the ROS signal, for example, would probably not disrupt any
of three Olivia signals in the bottom 60% of the ROS signal bandwidth.

In other words, the wide bandwidth required for ROS to work is a
disadvantage because IF filtering cannot remove narrower band

MMTTY provides a choice of three different RTTY decoders, with the ability
to shape the filters for each. There is also an optional bandpass filter and
an optional notch filter, with user control of shape for each.  As a first
step in improving MMTTY’s RTTY decoding performance, I am determining how to
optimize performance given the capabilities Mako-san JE3HHT has already
provided, using a setup similar to what Alex VE3NEA and Wes WZ7I  have used.

 

Note that on the chart Wes posted, WinWarbler running the HyperSensitive
profile with both the bandpass and notch filters enabled yields sensitivity
close to that of TrueTTY. WinWarbler uses MMTTY as its RTTY engine, so this
performance is possible with MMTTY alone.

 

I don´t have winwarbler but have mmtty….

Can somebody make a text how to setup mmtty for the hyper sensitive profile
that I can store it I mmtty as user profile

By synchronous detection, Vojtech, do you mean treating the first start bit
as the beginning of a synchronous multi-character sequence, thereby
providing some protection against “broken” start and stop bits within that
sequence? Brian K6STI referred to his decoding technique as employing a
“flywheel”, which I interpreted as a means of adjusting the synchronous
timing with high-quality start bits decoded within the sequence.

Here is another, similar chart:

I was comparing MMTTY with MultiPSK and gMFSK against RTTY in white noise.
Interesting observation was that MMTTY was better than MultiPSK at better
than marginal SNR, but MultiPSK was slightly better than MMTTY at very low
SNR. My best bet is that MMTTY is doing some kind of signal processing after
detector, which fixes some errors, but makes things worse in very low SNR.

Both yours and Alex's graphs show superiority of TrueRTTY and MixW. I wonder
whether TrueRTTY is doing synchronous detection. This is what I plan to try
when I retire, hi.

You look on the waterfall left or right of your actual rx qrg …. Click and
are tuned to the new station

I use this headphone sometimes for gaming and also when I work on the pc …

Very nice if you move your head just a bit and the mouse jumps over to next
position (or better say is following your eyes)

If you worked with the headphone a few time you will never use your normal
mouse again …

Because of 2 reasons…. You have your hands on the keyboard free for typing
and your mouse follows your view

It is also useful when working with texteditors like word or similar ….

Just look upper left corner of text, click and hold the button move your
eyes to lower right corner and release the button

“viola” the text is marked

Now push ctrl + c for copy or ctrl + x for deleting … etc….

There is a control stick with the headphone ..

It is like a mouse but without ball …. You hold it in the right for
controlling speed in games (with a slider)

Another wheel for changing weapons … some buttons under your different
fingers …

Didn´t try it for sdr but surely you can assign the needed things to the
controllingsoftware

I would suggest an intuitive interface; stereo headphones with tracking so
turning one's head tunes the receiver, frequencies below the tuned point
sent to the left earphone, frequencies above, to the right. Now just turn
your head until something interesting is audible "straight ahead", press a
switch or click on an icon and Bob's your uncle! (sneaking in English)

This could be pretty easy with some of the virtual reality gaming systems
but we might not need the video outputs. 

Or maybe we would Imagine spotting the multiplier you need on the heads up
display, turning your head until it's heard straight in front, and ZAPPING
it with the mouse. Nerd Preferred!

Hello Wes,

 

I saw the test file. It is nice except the long suite of figures, which
could be a cause of possible systematic failure (with many errors following
a first error) . Better would be to keep only the call signs which include
figures and letters and produce a good diversity (and so a more precise
statistic result).

 

Also it would be perhaps interesting to transmit the RTTY characters through
2 different programs because a program could produce a not exactly nominal
RTTY transmission and its decoding could match this transmission (for
example, the stop must be 1.5 bits but can vary in fact). If, with two
different transmissions, the results are the same, they can be considered as
reliable.

Dear Andy

What sdr and what trx are you using?

I use a icom 765 with a homebrewd downconverter … not a real sdr but I can
use the software that is built for if of 12khz

And it is possible to connect powersdr with hrd to control the trx

A friend from me did this with his kenwood ts2000 (no downmixer needed cause
last if is 12khz)

Betreff: [digitalradio] Digital modes with an SDR ?

 

  

My SDR receiver is due to be delivered tomorrow. I am looking
forward to using a wide band panadapter for receive and having my
transceiver sync'd for ability to transmit when desired. Since I
vacillate between CW and digital modes , I will enjoy keeping an eye
on both portions of a band at the same time. I am also looking
forward to trying Multipsk with is SDR capabilities and RS ID
combination. I assume there are many others with SDR transceivers or
receivers here in this group, and wonder how you are using it for
digital modes ?

AW: [digitalradio] Mystery signal on 75M

[Siegfried Jackstien]

Make a tap in your trx at the last if….

If you can downconvert it to 12khz there is a decoding software for this
…(dream)

I put a downmixer from 455 to 12khz in my icom 765 and now I can use that
software for decoding drm

It´s nice to hear a short- or mediumwavestation in stereo and noisefree like
a local fm-station

Also very nice on fieldday … I listen to RTL on mediumwave in stereo very
often (almost daily)

The downmixer is just a few parts on a pcb as small as a stamp

A mixer ic (sa612) and a few caps, and a ceramic-resonator … that´s all

with that 12khz if- output you can do a lot of other neat things

there is many software out in the net for sdr …

and most of them can work with that 12khz-if (or are written for this)

software like if-dsp (ik2czl), winrad, multipsk!, power-sdr, dream, … to
name just a few …

for receiving of drm you have to switch to am or fm on your trx …

you need that 10kc wide signal downconverted to the 12 khz if so your rig
has to be set to that wide bandwidth

the mystery signal is bbc / dw …. The 2 stations are sharing the
transmitting sites in sines portrugal and skeleton uk

and sharing the qrg 3995….

You find lots of info here:

http://www.drmrx.org/forum/

this is a listeners forum where receiving results , technical stuff and
other things are posted

AW: [digitalradio] What's new in SSTV ?

[Siegfried Jackstien]

Easypal and mmsstv are totally different ..

mmsstv is for "analog" sstv . every tone stands for a pixel in the picture

Easypal is "digital" sstv

The pixels (or any other data) is computed with error correction and other
things .

The whole thing is the transmitted in packets (or better say segments)

On the receiving side the segments are stored and brought together as one
file

If there are bad segments (or some are missing) the receiving station can
send a BSR

That is bad segment request . the sending station now repeats only the
missing parts

If everything is received well the file is displayed .

So easypal gives you 100% copy (or nothing)

With easypal you can not only transmit pictures .

You can send ANY digital file ..

Text, pictures, and software

So maybe this is a bit of help for you ..

The new units I have been looking at have an optional module that is

Are the TNC connectors on the back of the unit that don't have an internal 
TNC merely sound input/output circuits?



If there is NO tnc behind the serial connector this is a serial portfor

If the signalink is a new one maybe the changes are already made . see at

But maybe somebody got a used one that he found on e-buy ..

So just a quick check with spectran or any other spectral software and you
will see if you have to change the transformers and the caps ..

Hello to all Group Members...

I am new to the Group - a 74 Yr Old -just returning to Amateur Radio, after
an absence of nearly 40 years, licenced in 1956, when 'Digital' was just
RTTY, and using 'proper' Teleprinters - Such as the Creed 7B (Anyone
remember these 'clatterers' ? !).

OK - I am new also to Digimode - so perhaps my unbiased view on the topic
here may be helpful (or not?).

I accidentally discovered PSK 31 about a month ago, and since then have
downloaded the many Digimode programs from the net for evaluation for my
needs, and read all I can on the topic, to get insight and knowledge. I
started by just listening (or is it 'watching'?).

I now have bought a 'proper' interface, and just this week have started
transmitting. Only able to work contacts around Europe - Italy, France,
Germany, Norway, Russia, etc on 40M at present, but am sure I will get
further when my antenna is upgraded from a 20ft length of copper wire end
fed through a 9:1 Balun at 15ft hight, to something better I am building.
Plus when (and if!) the Bands 'Open Up' - I don't hear European stations
working anything outside Europe at the moment, so I am quite happy that all
is working as it should!

So - after a long winded pre-amble - here is the reason I write all this, in
this thread ! ... The Thread starter was wanting to know what
Transceiver to buy for Digimode, that was good and cheap . Answer from
me I am using a 150 dollar (off Ebay) Kenwood TS 520SE 'Boat Anchor' -
and love it. It does all I need and more, it has all the facilities and
Specs that I need - and more, and - It was cheap !!!

Sorry to 'ramble on, but when you are 74, you have earned the right to bore
the ass off everyone !!! 

If - by some strange reason, you are interested in reading about my setting
up the current station, all about the Kenwood TS 520SE Line, and my Amateur
Radio 'Blog' - there are three really big pages of it among all my other
interests on my web site at www.John4Music.TV

All the best to everyone in the Group, for the coming 2010,

Kindest regards,

John G3OBU

AW: [digitalradio] TS2000 and SDR I.F. Stage Use for digital moded ?

[Siegfried Jackstien]

A friend from me married power sdr together with hrd for controlling his ts
2000 and used the sdr soft for receiving

Don´t know if it is what you need …

As I know he took the 12 khz if out of the ts 2000 without any additional
mixer ….

But if you put a downmixer at the if stage it is better cause you have the
wider bandwith for the panadapter

So the receiving bandwith depends on your soundcard

So put the downmixer at the second if BUT before the narrow bandfilters….

That can be easy done with a ne 612 and maybe a little preamp before it

I don´t know if you can use yozur softrock for this …

http://www.ham-on-air.de/?p=4152

this is a video my friend made … I think it explains a lot

if you will not need the panadapter but only the software for receiving via
your pc

you can use lots of soft like winrad, power-sdr, if-dsp (ik2czl), and some
more ….

100% agree dave ….. very well written ….

My spezial „contest“ without points or any ranking is :cracking a pile-up
with my 100w barefoot icom and

A wire antenna in my backyard ….. that is a test for my personal skill ….

Listen listen listen with switching vfo a and b …. Find out where the dx
station is listening and get trough

That is what I like to do ….

With a gallon and a 6 element monobander it is easy ….

With barefoot and a wire … you can do this if you find out where the dx is
listening

The big factor in ham radio contesting is MONEY.  If you have a lot, you can
virtually buy your way into the big boys club (in fact - that is what makes
one a big boy).   That leads to the very large array type contest stations.
Of course, they are going to win out every time ove the guy sitting at home
with 100 watts, and dipoles, and even those with a kw and/or a 100 ft tower
and 6 element multi banders.  And before anyone starts yelling SKILL SKILL
SKILL, at me;  think on this.  Two people, with who wind up on the same
calling freq, at the exact same time, call the DX.  They live across town
from each other, and the propagation  cloud favors each other the exact same
way.  Nw - who is going to get thru first?  First will be the guy who has
the better antenna?  Or the person with the higher power?  Yes- voice can
and does have some input here, and the one who has a better "radio" voice,
has the best chance.  Lets say one is a YL, and one a deep husked OM.  You
know who will make it first in that case.  But lets say they are twins, and
not only use the same radio, but the same mike.  Now who will get thru?  

 

How often will such take place?  Not at all likely,for sure, but if one has
6 elements at 100 feet, and the other 3  elements at 30 feet,you can bet the
one with the higher antenna will get thru first , 99 percent of the time.
So, again it comes out to money.

 

So what does all this mean?  Those who are really "equal" in
equiptment/location etc. really do have an equal opportunity in the test.
Those who have lesser equipment, must then depend more on their skills, in
order to compete.  Yes - their are different levels of competition, and
those with 100 watts and a diipole can and do get in the contests, and
sometimes even win - as long asthe competionis others within the same
equipment constraints.  But, given just a handfull of stations running the
same 100 watts, but with a multitude of very tall towers, then the former
might as well take down and pack their shingles, as far as putting paper on
the wall goes.  

 

The very best time Ive seen, contest wise, was my first and only Novice
Roundup. Limited to 70 watts input, we didnt have "power" stations in there
competing.  And, yes, some did have better antennas than others, but the
vast majority were just younger guys, with no money to speak of, and who had
thrown up homebrew wire dipoles.  Ones skill and wile really did make all
the difference in the world.  TheWorld Radio Championships of today are sort
of that same way.  Each pair of contesters, assigned a station with similar
antennas, power, and location: competes only against others of the same
class.  The winners?  Those who prove themselves to be the better tacticians
and on-air operators!  That is real contesting.  Any of us can be invited to
a multi-multi big boy station, and sit there our apponted hour or so at a
time, and yell into a microphone, hooked to a rig (set on one freq the whole
test), running into a KW max output, run to a 4-7 element single bander and
score point after point after point.  

 

Now lets dont take this wrong, many, and probably most, of those operators
are indeed the top cream of the crop , and that is why they have been
invited there in the first place- having proven themselves in their own
stations as top notch contesters, over the years.   They are given the
leeway to change freqs as necessary, according to props, and to start
searching when their thruput numbers start to drop, etc.  So, their actual
radio skills do come forward at that time.  Of course here, we are talking
of SSB ops.  The CW world is a whole other thing.   Contest stations dont
invite the slow and unskilled to participatein those stations, during a
contest.Those operators are indeed picked from the "already skilled".  

 

But to get back to the "equal opportunity"  that the rest of us face, its
pretty not much there anymore, unless you have the money to make your
station better than everyone elses, there is NO equal opportunity for you,
and doing that no longer gives the other an equal opportunity competing with
you.   Self esteem come from what you do, with what you have.  There appear
to be more an

Yes I can do ….. with echolink … but there is something missing in the
system …

It should be possible to connect to an echolink node and tell the node that
you are available via this node (with dtmf tones)

Something like the mybbs in the packet net ….

Nowadays if I move through the country I have to start the contact to my
hamfriends at home cause they do not know where I am in this moment ….

If I wanna connect o another friend who is somewhere in the country we have
to make a sked on a third node

(1 node where he is, 1 node where I am and another node that we know the
number of to make a sked)

In the other way when telling the system that you are in the area of node
xyz it would be a lot easier …

Somebody knows my nodenumber at home or calls me via call sign … the system
knows that I am not at home but available at node xyz ….

Now there are different ways

The node where my hamfriend connects to echolink tells him: dg9bfc is
available at node number 12345

Do you wanna connect? Push button 1 ….. node says : you will be connected to
node 12345

Do you wann leave a message? Push button number 2 …. And leave the message
in the system

Now echolink makes a store and forward to the node where I am and plays the
message

that would be an echolink system what I would like more as the today system

no question echolink is good but it could be used from more hams if it was a
bit better in some cases

hams who don´t even have a computer have a unique number cause you can also
call in echolink with the callsign

hams who have connected to echolink with a pc have more than just one number

the number code from their callsign and the nodenumber from the pc when they
are at home

so when somebody calls my homenumber and the pc is off …. there could be an
announce that tells the other guys that I am not at home but reachable via
xyz

or an announce to leave a message (at my home pc if available or in the
system with s+f) … etc. etc. etc.

It is for audio and you can connect your radio to your pc and walk through

Hi Sigi,

Yes, Echolink is a wonderful example of a 

modern networked radio communication system. 

Can you please tell me which HF frequencies 

and modes in europe you use to ring up your 

friend with echolink? How can you ring up your 

friend day and night with it on HF? Does anyone 

have a multi-band HF node on Echolink?

I ran an HF-SSB voice echolink node for over a year, 

on 5371.5kHz and 18157.5kHz. It was fun and useful. 

Over 1000 hams used it during that year. Some 

of the more interesting QSOs on it were the ones 

with the most distant and unusual situations.. . such 

as: A european ham on holiday, walking along a 

beach in Canary Islands on a 2m FM HT, talking with 

an american ham hiking with a PRC-1099 manpack on 

20W SSB 18MHz in Colorado USA.

But of course, all the connections were manual 

operation with voice calling. Echolink lacked the key 

signaling and alerting feature to ring up someone 

if they were not listening to the speaker. It also 

lacked "remote PTT", so it had to be manually monitored, 

the old way. Perhaps the recent software updates 

have added new alert methods or remote PTT? 

The use of DTMF tones for signaling from end-to-end 

is not available in most systems due to many repeaters 

auto-muting DTMF. This makes it difficult to add 

any type of universal on-channel audio signalling.

snip..

I do not wanna use dtmf for on channel signalling ...

Just e number code that the echolink node knows YOUR nodenumber ..

The number is normaly in the system when you connect via your home pc ...

Now if you move trough the country your node pc is off or switched to -r or
-l mode .  (maybe for bringing another node on the air for other hams) so
your normal number is not in the system..

With a special number (say your own number is 22334) for instance **99*22334
you tell the system that your number is 22334 and you are now in the area of
the node where you played your number in and if any calls you the call
should be forwarded (or a stored message of maybe 30sec. is store and
forward to the node where you are and played to you)

Everything is possible with only the dtmf tones on the rf side (not via
internet audio)

The other way is right . the dtmf tones MUST be muted via internet audio .
or the system will not know if the tone is for the node where you connected
or for the node that you are connected with...

I am sure that this function is possible ... maybe with another number
behind it for giving your MYNODEnumber a lifetime .. (**99*22334*(1-24)* for
lifetime of 1 hour to one day max...

So if you are on holiday somewhere ore are working somewhere in the country
you have to tell the next available node your number and you are available
with your homenodenumber ...

So you do not have to connect your friends manually and tell them where you
are now and what nodenumber you are connected with... that function would
make echolink work as a cellphone (almost)

No automatic roaming .. But a manual roaming .. If this would be implemented
in the soft it would be only a small step to mute your receiver and have a
dtmf receiver built in that rings when your number is transmitted from the
node

Next connect your car alarm horn to a relais .. just kidding ...

But the other things I wrote are an idea how the system could be upgraded ..

Just my 2 cents

Dg9bfc

Sigi

Ps we should not make another and another and another system like echolink,
wires, amfones, and the new d-star etc We should try to bring up a system on
the air that is cheap, easy to work with, and can be used with a simple dtmf
mic as the minimum requirement ... and upgrading echolink would be such a
system .

AW: [digitalradio] Simple PTT interface circuit ISO

[Siegfried Jackstien]

The easiest would probably be ….take an usb – rs232 transformer ….. and now
you have a rs232 on your laptop

Now take a optocoupler  …..wire in series with a normal led the led side of
the opto

Now with emitter to ground and collector to ptt circuit is complete

The opto with the led should go to rts and ground …. If the rig key reversed
(soft is on receive, trx is keyed)

Reverse connection on rts and ground of the led´s

High signal on rs232 is minus 5-12V and low signal is plus 5-12 so the led
should light when minus 5v are on the rts pin

Maybe a small resistor in series with the leds if you have a stationary pc
cause there the voltage on rs232 is 12-15v

With the usb _rs232 transformer you have only +/-5V on rts …..

Rs232 is current protected at 15-20mA so the led and the led in the opto
will light and the opto will switch trx

Cause you need only 2-3 parts everything can fit in a rs232-plug

AW: [digitalradio] lpt to com port assignment?

[Siegfried Jackstien]

Use a serial port . not lpt . and surely not the 15pole connection . this is
for your monitor

You find the serial port at the backside and it is 9 pole in two rows . one
with 4 and one with 5

If you have no serial port (only usb) there are several usb-serial
transformers available for a few bucks

If you have now a serial port you should use an optocoupler for triggering
ptt on your trx .

Just google psk31 modem or something and you will find lots of circuits

Hope I could help

Betreff: [digitalradio] lpt to com port assignment?

 

  

Hello all,
I am trying to set up my computer to key my radio rather than the el cheapo
way of using vox. I have built a circuit to use the 25 pin lpt jack, but I
do not know how to assign this jack as a com port. Most of the digital
programs I use only specify com ports, not lpt. I do have a 15 pin
connection, but I am not sure what the proper connection would be. I am
obviously not very knowledgeable about computers, so any help is
appreciated.
Thanks, Daniel

Andy, although I have not tried it with my TS200/TM-D700 combo yet, my
question would be, why not put a dual bander antenna on the TS2000 also in
place of the monobander UHF antenna that you must have to pull this off as
you have stated? Would seem that you could then have the best of both worlds
in the mobile AND at the BASE ...

Keep us posted on your results, should not be any reason you cannot do it as
described, albeit there may be some delays that could cause some digital
issues with FLdigi. Are you planning on any form of ARQ?

thought I might try the Sky Command capabilities that my rigs have. Anyone
already done this and perhaps have the set-up files that can be shared ?
