I'm curious what are the benefits or disadvantages of using Rig or Fake it for split operation? My rig supports split so is it better or is it just preference?
Hi Yancy,
The split operation using Rig is a native operation of those rigs that support it. It is usually faster as the transmit VFO it already on correct frequency, CAT command just selects it.
In the Fake it option one VFO is first commanded to the transmit frequency and only then actual transmission may start. In some rigs that may take some time. There may be other reasons I don't know.

Hi Tim,

I hear that 144.46MHz is used for FT8 in Japan due to the band plan. It
seems that 144.173MHz, which is set as standard in WSJT-X, can only be used
for EME with overseas in Japan.

Hi all, We're seeing amazing FT8 TEP between JA & VK on 6m this month and
a number of us were wondering what the FT8 frequency being used in JA, BM,

someone can point us at the right frequency for JA etc. thanks Tim --

Hi.

In JA, we use 144.460 for FT8/FT4/Q65 and BY/BV/HL also are on the frequency when we have Es hop.
We might want to consider using Q65 as evening TEP generates signal distortion even on 6m.

I discovered recently that even though it doesn't show in my tx window that when I call cq w0gmv it is also transmitting to the right "CQ zone 4" and don't know what I did to cause this, it was USA but now CQ zone 4 and can't find where to change this setting.

I agree with Dave's suggestion. Download and install JT-Alert and under
Help, read about configuring it to work with WSJT.

Under the Alerts menu setup the States wanted, Countries wanted, etc.

Go to Settings>Manage Settings and click Alerts then setup the Alert sounds
you want played for each type of Alert. JT-Alert has its own set of
default sounds for each alert.

Under the View menu, select the Callsigns window. When each wanted state or
country is decoded a box will appear in the Callsigns window and you will
hear the name of the state, country (based upon how you have chosen the
Alerts settings in the configuration menu) announced over your speaker.

The color of each type of Alert corresponding to the default or custom
alert settings in the Colors menu.

JT-Alert is an indispensable tool to use with WSJT and really adds to the
overall digital modes experience.

Also, it has a lot of customizable features that you can set to your own
preferences.

You can download JT-Alert here:

Good luck! See you on the waterfall.

Unless they run on internal batteries, and unless those batteries are NOT recharged from the USB port, USB speakers are likely to cause RF noise on the ham bands. Neighbor W6GJB found enough RF trash on the cables to his to read on an MFJ RF current probe, and the noise was quite strong. The culprit was likely DC-DC converters to convert the USB port's 5VDC to a the voltage needed by the built-in power amp.

If you haven't done a serious RF noise survey of your own home, study either of these two pdf files.

Michael Ernst <mernst@...>
 

I have made an interesting discovery. I also have a set of USB speakers plugged in to this PC. I have them set as the default sound device and the USB audio codec as the default communication input device. If i switch from the USB speakers as the default input to the Realtek Audio card (which has an audio jack, but no speakers plugged in) the error goes away. As soon as I switch back to the USB speakers and allow JTAlert to broadcast the various alert messages, the error occurs. So it seems to be a conflict between the USB audio and the USB audio codec. I am going to try plugging in some standard audio speakers and try to further isolate the problem.

Well, correct Mike. I assumed that Paul can receive both frequencies at the same time. But I forgot that one will be 10 kHz higher audio frequencies. He should have already two receivers or somehow convert the higher one down to another audio stream. Perhaps Spectrum Lab program could be used for that purpose.

Only if you have dual VFO reception.I can do this on my Apache ANAN 7000DLE MKII but not typically available on most rigs.

As said my configuration is set for the K3 to operate using "RIG SPLIT" I do not use Fake it.

After the QSY was invoked by the other station only my Tx VFO (B) moved leaving the Rx VFO (A) listening on the original frequency - it all works FB on MSK144

I believe the current maximum is 5kHz.
The audio data is down sampled to 12kHz which means there's only 6kHz of the FFT available.
Generally FFT processing runs about N^2 so doubling the sample rate to 24kHz tp get 12kHz of width would approximately square the run-time required to process it.

locked Re: Simulating logging in WSJT-X to verify other software #networking

Williams, G (af8c)
 

There are some other ways to attack the problem.  Why use UDP?

1)  Simple DOS batch command files can pull out the data from the log files growing in the %localappdata%\wsjt-x tree. I have 5 or 6 various DOS batch files I wrote and use.  A C-language (or other) utility could do that also.  You only have to do that once every 5 to 30 seconds depending, not anything like multiple times per second.

2)  With two networked computers, a second computer can look into your WSJT-X tree with proper coding and do what (1) does.  I believe that N3FJP loggers can access WSJT-X.

Hi Björn
For sure developers have suitable tools for that. You may get more information on the wsjt-devel list. Personally I have used a brute force solution having two PCs and audio connection between those. Running wsjt-x on both you can make real QSOs on any mode, hi! Of course it is a slower solution than any software tool.

I personally dont find ft8 /ft4 as a "ragchew" type mode, so I dont expect
anything other than the RRR or RR73, then move on, or qsy. I think the
reason you dont get an answer may be that very reason, or if you are not

I have notice many using free form, but do they expect an answer, like ok

Hi,
I think this is specific to FT8 with regard to free text faciltiy but
could be wrong, and apologies if this has been addressed before (did a
search).
OK, I have been using the free text box 13 characters to include tiny
conversational input by replying to "RR73" with "GREG100DIP 73" (assuming I
called the guy). The content is hopefully self evident. My query is that I
never get a response and wonder whether:

1) The 13 char free text relies on stronger FEC or whatever so that it
may often not get through
2) Since the other guy's call is not included then perhaps the text
doesn't light up in colour on the other guy's screen so is missed (to
include call would severely limit already severely limited text field). But
in that case the freq would be the same at least and the text would occur
in the Rx frequency box which would help identify it
3) It's boring so never gets attention, but then conventional qso's
generally include some additional info (excluding contest stuff)

I feel like I'm missing something here. Thoughts?
