Re: [wsjt-devel] Tone spacing

[David Alloza]

Thank you for your answer Bill,
That's all clear for me.
We will try jt9 fast mode.
My 73,

Hi David,

the tone spacing adjustment is only on transmit and is designed to 
accommodate transmitters that divide the modulated RF to make the 
transmitted signal, usually to make transmissions on the lower LF bands. 
They would normally use hetrodyne mixing to up-convert before the IF 
receiver so no tone spacing adjustment is needed there.

Have you considered experimenting with one of the JT9 fast modes or even 
MSK144 if you want a block encoded mode like FT8 or even ISCAT for a 
stream encoded mode that can work well with complex and variable 
propagation paths like aircraft scatter.

Greetings,

Thanks to Joe for taking his valuable time to respond.

I didn't realize that the Enable TX should stop after each QSO.  
Apparently it does in V2.0.0-rc1.  However, tonight I am back running 
V.1.9.1.  I have made 5 QSOs in a row on 160m with out having to do 
anything other than select TX6 CQ after each QSO--the ENABLE TX glows 
red all the time just fine.  I am that good! I guess I broke the 
software! I don't see a problem, however.


You were in FT8 mode right?   It has been the default since the beginning.



"An automated QSO machine" I'm not even sure what that means I guess.  
The software user still has to perform functions to get things to 
dance.  If there is a problem with user abuse of the software limiting 
the software/user interface isn't the solution IMHO.


By an automated QSO machine it means that the program does everything 
without human intervention.    You can turn off the 'Log QSO' and the 
program would save all the QSOs to its log, and then all the 'operator' 
would have to do is import that log to LoTW and get credit for 'contacts'.




Another HAM in my region suggested a potential abuse of the DXpedition 
mode that I hadn't considered.  DXpedition is on say 30m and it is 
after midnight local time.  HAM starts calling the DX and goes off to 
bed.  Wakes up fresh in the morning and sees DXpedition in his log.  
This could be a "problem".




Can't happen as there's a built-in watchdog timer that forces the user 
to again "Enable Tx".




If I am sitting in the chair, interacting via the interface screen 
(could be tested for) then don't turn the ENABLE TX button off after 
each QSO.


How do you prove you're always in front of the computer?   Clicking 
Enable Tx after you click OK to Log, takes a second or less and insures 
that someone is in front of the scren.





My biggest interest is using WSJT-X and my stations equipment to make 
contacts over circuits that are on "dead" bands, or where my antenna 
is a compromise, etc.


Thanks to the WSJT-X team for their efforts.

73, Jim, N8OQ

Re: [wsjt-devel] Missing Auto Seq and Call 1st in JT9 & JT56 in wsjtx-2.0.0-rc1-win32

[Neil Zampella]

Um ... I don't remember JT65 or JT9 having any auto-sequence setup in 
WSJT-X.   They are both 42/46 second Tx cycles, plenty of time to 
dbl-click on a decode.

Could they please be reinstated for JT modes ?

[wsjt-devel] Using Multiple configuration

[Alessandro Gorobey via wsjt-devel]

Hi All,

I run the calibration cycle on my radio without problems, but using 
multiple configuration only the my "FREQ-CAL" is updated.


I can import/export single or multiple frequencies, but not the 
calibration data.


I stopped the program and edit the ini file with a text editor.

Old fmt version included in wspr write a fcal.out file with the two 
values needed.


Can be a idea?

[wsjt-devel] WSJTX V2 sample files

[Alessandro Gorobey via wsjt-devel]

Hi All,

I noticed that if I try to download the sample files I get an error.
I think it's enough to copy
https://sourceforge.net/projects/wsjt/files/samples/contents_1.9.json
to

Thanks for your report.  Unfortunately you give no examples of false 
decodes, and no *.wav files for received data that produced a false 
decode.


Please follow these instructions in Quick-Start Guide to WSJT-X 2.0

"Remember that the most useful bug reports include a concise description 
of the problem, an exact sequence of steps that will reproduce the 
problem, and (if relevant) a *.wav file that causes the bug when the

*Save all* when operating with a –rc# release candidate."


and send us useful diagnostic information.

Re: [wsjt-devel] WSJT-X and disable TX after sending 73

[James Shaver]

Had that other ham read the documentation that goes along with the DXPedition 
Mode, he would realize that for “Hounds,” the transmit cycles is automatically 
disabled after a few cycles no matter what the operator selects as options.

Re: [wsjt-devel] Missing Auto Seq and Call 1st in JT9 & JT56 in wsjtx-2.0.0-rc1-win32

[charlie]

Hi Justin

As far as I can see, autosequence operation with JT4, JT65 and QRA64 is
the same with 2.0 as it was with 1.9 (at least the check box to select it
is present).  I have not yet had the opportunity to test its operation on
air.

As well as FT8, it was available in 1.9 for JT4, JT65 and QRA64.  The user
guide (section 7.3) also notes that it is available for JT9 but it does
not seem to be on my build of 1.9.1, so I am not sure about that.

Autosequencing was added to the above slow modes to assist in high
workload situations such as EME,  and for this reason only works when
VHF/UHF/Microwave features is checked.
