I said nothing about running power.  I said strong signal, wanting to have a 
way to only allow display or decode of weaker signals, the level of which I 
determine and set.  This is similar to the function available in DXpedition 
mode.

 This would be a big help to have callsigns color coded, would it also be 
possible to code in filters where some messages are not shown such as other on 
going qso`s that are not necessary to view and even stations that have been 
worked B4. This would de-clutter busy screens that have so many decodes you 
cannot even view them all. I sometimes feel this is why some stations are a 
sequence or two late answering callsthey do not see them they have scrolled out 
of view. These could be an option only if the operator wanted to 
activate.Thanks for your consideration73 wa4mit Morris

[wsjt-devel] Callsign highlighting

2018-03-23 Thread Alex, VE3NEA

Hello,

I have written some code that allows a UDP server, e.g., a logger, to tell WSJT-X what background color to use for each callsign 
in the Band Activity panel. This might be useful to those who chase various awards, if the logger assigns different colors to 
new IOTA groups, US counties, etc. The end result looks like on the attached screenshot. The .diff file is here:


http://www.dxatlas.com/Misc/callsign_highlight.zip

The zip also includes a Delphi class for listening and replying to the WSJT-X messages, and a demo program that shows how to use 
the class, which is also useful for testing the new feature once it is included in WSJT-X.

Re: [wsjt-devel] New FT8 Frequencies?

2018-03-23 Thread gary
OK guys, at the risk of sounding like a cracked record or a corrupted MP3, I’ll 
give this one more shot.

 

Anecdotal reports tell us very little except in your opinions “The FT8 segment 
looks crowded”.  I agree, that is how it LOOKS.  It LOOKS crowded here too … 
and yet we are still making loads of FT8 QSOs with little hard evidence of 
problems due to overcrowding.  Repeatedly re-stating “It looks crowded”, 
sharing busy waterfall snapshots, counting decode rates and telling us it is 
“imperative” to expand the allocation, is getting us nowhere.  

 

In fact, Bill, your comment that you are seeing “nearly 50 decodes every 15 
seconds” when the band is busy tells us it is working just fine as it is.  Your 
own waterfall pic shows all those FT8 signals sharing roughly 2,000 Hz of band. 
 In theory there is room for 40 optimally-spaced 50 Hz wide FT8 signals with no 
overlaps in 2,000 Hz.  The ‘extra’ ~10 decodes you see probably include a few 
outside the 2,000 Hz segment, and others where signals are overlapping. 

 

I often see overlapping signals decoded successfully, sometimes separated by 
just a few Hz and occasionally fully overlapped on exactly the same frequency.  
FT8 does a much better job at separating overlapping signals than we do simply 
by looking at our “overcrowded” waterfalls.  But of course there are limits to 
the magic of FT8.

 

Based on the above, and actual experience every day on the air, I could 
conclude that there is plenty of capacity remaining and no desperate need to 
expand the HF allocations … but what it doesn’t tell us is how many additional 
signals might be present that are not being decoded due to overcrowding, nor 
how the FT8 band occupancy is changing.  If we are not currently experiencing 
severe overcrowding, are we days, weeks, months or years away from that crisis 
point – or will band occupancy automatically level itself out as people shift 
to other less occupied bands and modes?

Gary  ZL2iFB

This is 20M about noon in Tampa Fl area on a ground mounted vertical. This 
picture is with about 35 decodes every 15 seconds.

During the most active times on 20 & 40M  I can see nearly 50 decodes in 15 
seconds. Imagine Ops with better antennas see even more decodes.

This picture only shows the strongest of signals as well. There could be weaker 
signals under the strong ones.

For those who would like to track stats on the various modes see: 
https://www.pskreporter.info/cgi-bin/pskstats.pl middle of the page.

Activity on FT8 is amazingly higher than any other mode and will only increase 
over time.

Lets see what ultimately happens.

I have also heard grumbling among the PSK31 and Olivia crowd that FT8

conflict. WinLink and Pactor may expand, especially if the new
Technician privilege proposal is approved by the FCC.

So any change has to be considered carefully and with the
understanding that we may just not get what we want.

How do you know we're running power? I run gain antennas including a 3
element beam at height on 30 meters. I get complaints from some that I
am running excessive power. (I run 50 watts except on 80/160 and 6m
where I will run up to 1500W)

Should I just run a G5RV so as not to bend the needle now?

This brings up a topic I would like to see discussed.  Similar to the 
DXpedition mode, I would like to see a setting available to either ignore or 
not even display signals over a certain SNR.  For instance, allow me to say I

Hi Frank,

a couple of clarifications.

The jt9 process does not directly handle audio samples, they are read
and written by a thread of the wsjtx process.

The jt9 process is monitored by the wsjtx process and failures are
reported via a message box including the reason for failure.

If the source of sound samples stops delivering samples; the wsjtx
waterfall and decoding will also stop.

Hi Bill,

interesting Information, because :

Soundcard has an indicator LED, LED ON means, power ok.
Flashing means data is being read from the soundcard.

And the LED is flashing(all the time)even when waterfall and decode
stopped.
-> wsjtx reads data from soundcard??? but does not pass data to jt9 ???

No Error Messages are generated in wsjtx.

Behavior is the same like I'm pulling USB cord while wsjtx is running->
no message is generated and decode and waterfall is stopped.


Hi Frank,

the general overview is that a thread of the wsjtx process gathers 
incoming audio samples and passes them in chunks to the main UI thread, 
there they are used to drive the Rx level indicator and the waterfall 
graphs. The gathered samples are also accumulated in a shared memory 
buffer and when decoding time arrives (determined by having enough 
samples) the jt9 process is woken from an idle loop to do the decoding. 
Decoding results are passed back to the wsjtx process via the jt9 
sub-process standard output stream.


Your issue could be explained by a USB communications breakdown, the 
flashing LED may not indicate that data is being streamed over USB, just 
that the sound card ADC is active. If the WSJT-X Rx level indicator is 
not showing a level *and* the waterfall stops scrolling, then it is 
fairly certain that the operating system is no longer delivering audio 
samples to the application.

2018-03-23 Thread rjai...@gmail.com
One of my friends has reported something similar - decodes stop for no
reason and start back at random. He doesn't use a Raspberry Pi. He
uses a recent 27" iMac and runs Windows in a Parallels instance. The
rig is a Flex-6300 and uses the COM port for CAT control (via SmartSDR
CAT).

CPU usage seems fine, memory usage seems fine. We have been unable to
pin it down. Audio from the Flex DAX sound card device seems fine too.
Clock is sync'ed.

He's using 1.9.0-rc2 (I'll ask him to upgrade to RC3).

Just a data point.

Hi Bill,

interesting Information, because :

Soundcard has an indicator LED, LED ON means, power ok.
Flashing means data is being read from the soundcard.

And the LED is flashing(all the time)even when waterfall and decode
stopped.
-> wsjtx reads data from soundcard??? but does not pass data to jt9 ???

No Error Messages are generated in wsjtx.

Behavior is the same like I'm pulling USB cord while wsjtx is running->
no message is generated and decode and waterfall is stopped.

Re: [wsjt-devel] New FT8 Frequencies?

2018-03-23 Thread rjai...@gmail.com
I would concede that in Europe it is a problem. My antennas are beamed
to Europe most of the time but there aren't many strong band openings
these days.

I have also heard grumbling among the PSK31 and Olivia crowd that FT8
is interfering with them. They can move but when we move it may cause
conflict. WinLink and Pactor may expand, especially if the new
Technician privilege proposal is approved by the FCC.

So any change has to be considered carefully and with the
understanding that we may just not get what we want.

Re: [wsjt-devel] New FT8 Frequencies?

2018-03-23 Thread George Molnar
The digital mode watering holes are not (as far as I know in most cases) part 
of any international agreement or national regulation. If a group of operators 
want to agree amongst themselves to operate on a particular spot, it is 
incumbent on them to avoid interference with existing operations and be “good 
neighbors.” Don’t think it is the dev team’s job to dictate slots (and they 
have been extremely thoughtful in this regard).

It seems JT9 and FT8 would be the best fit for side-by-side operation. If the 
FT8 watering hole is crowded where you are, may I suggest that sliding up a 
couple of kHz would be an acceptable practice? In most situations, this will 
leave the JT65 slot open for very weak signal users.

Users can add frequencies to their configurations very easily (see the manual). 
Wide receive passbands are possible on some radios, and who knows, this may be 
a spur to future I/Q stream development, allowing even more bandwidth to be 
guarded at once.

2018-03-23 Thread Andras Bato
It's only you Ria!
All FT8 subbands are much too crowded, even in the WARC bands.
We badly need the higher bands like 21, 24 and 28 MHz but it takes several
years when
there will be regular openings on those bands.
I am terribly surprised when you are living in the USA where there are
ARRL, IARU HQ,
and Administrative Council members like K1ZZ and the president is a
Canadian.
Is it a problem to ask them for their opinion and propose new band plans
which would precisely devide e.g. the digital band portions
to RTTY, PSK, FT8, JT65, JT9 subbands?

I don't think there needs to really be more room. There are several
bands that we can use. I prefer to use WARC bands because I have my
fill of DX on 20 meters but WARC bands offer additional opportunities.
Especially 30 meters where I have gain antennas.

There's over 7K members on the Facebook group.  Maybe post upcoming DXpeditions 
under the "Events" heading along with dates and frequency(s) that'll be used.  
The "Events" heading is always at the top (on the left) so users won't have to 
search thru all the postings.

 

Maybe a link to any webpage posted by  DXpedition too.

 

Probably a good idea to go thru periodically and delete events that have passed

noise floor on the 30M is 5db higher than on the rest of the 30M band.

The concentration of traffic on the narrow 2.5khz (certainly at excessive 
power)  causes a significant rise in the noise floor and therefore reduces the 
performance of this mode.

I think this is something that needs to be considered for the future of these 
digital mode.

My 73,

David, F4HTQ.

normal day to day FT8 operations.”

 

On the contrary, Rich, it is plainly evident that in normal use we can 
successfully pack in loads of FT8 signals sharing the present fairly narrow 
slices of the HF bands.  Don’t get me wrong, I fully support the idea of 
monitoring trends and projecting forward but, as things stand, I see very 
little hard evidence of an impending crisis.  Just because there are few 
obvious clear columns on the waterfall does not mean the band segment is 
“full”, since in practice FT8 is extremely good at separating overlapping 
signals.  So I refute your assertion that “there is no doubt” that additional 
frequences are needed.  There most certainly is doubt, hence I disagree that 
expansion is “imperative”.  

 

A more scientific way to address issue this would be to gather and analyze 
data, objectively, rather than us simply asserting and refuting stuff, 
subjectively.  So what data would be needed?  How would it be gathered and 
analyzed?  By whom?  These questions are worth exploring.

 

If the data indicate impending crisis, there are other concerns about the 
options for avoiding or resolving it.  Aside from the problems 
making/taking/stealing space from other modes to allow for more FT8, being able 
to monitor all the FT8 activity on one screen at once is a major advantage of 
the current arrangement, whereas splitting it up across additional band 
segments will make things harder.  It could prove counterproductive.

 

Having said that, though, I agree there clearly are incompatibilities and 
conflicts between normal everyday FT8 activity and the new DXpedition 
fox-n-hounds mode, so I would agree with the suggestion to make more space for 
DXpedition use, specifically.

 

I’d therefore like to make a suggestions: how about we designate a digimode 
DXpedition zone on each of the HF bands without specifying the digimode?  That 
way, the same chunk of band can be used for RTTY, PSK, FT8, JT9, JT65, CW or 
whatever the DXpeditioners choose, and revert to being a multimode segment when 
no DXpeditions are using it.  It would be a good place to experiment with new 
modes and variants, for instance.

 

There will still be occasional conflicts if multiple DXpeditions attempt to use 
the area at the same time, which suggests they might need to slice the zone 
more thinly and stick to narrowmode digimodes with tighter pileups, or agree 
amongst themselves some sort of schedule, or simply check that the area is 
clear before transmitting – standard practice for polite DXers.

PS  This thread is not really about WSJT-X software development, hence we 
should probably shift over to the other WSJT-X reflector.

As we all know, when bands are open, it is not unusual to find the standard FT8 
frequencies packed, end-to-end with stations. The waterfall is full of dozens 
of QSOs and many more dozens of stations calling others. There is no doubt that 
with the super success of the FT8 mode, it is imperative that additional 
frequency “Channels” within each HF band be identified for not only the new 
DXpedition mode, but more importantly for normal day to day FT8 operations. 
Although the number of JT65 users has greatly dwindled, there are still many of 
them using the mode on HF, so these frequencies and their JT65 users should be 
left alone.

 

The same holds for PSK31 and its army of Hams who like its rag chew 
capabilities that the FT8 and JT65 modes can’t provide. Then there is, on a 
normal weekday, a vast wasteland of the 14.080 to 14.099 RTTY band. When you 
tune across that frequency range during the week, rarely do you hear more than 
a few RTTY signals, while at the same time, packed into 2 KHz, many dozens of 
FT8 stations can be heard working each other. The only times that the RTTY band 
comes alive is during weekend RTTY contests and during DXpeditions to countries 
that RTTY users need to work
