Gene,

it was only a suggestion, CI-V Transceive Mode causes the rig to emit unsolicited CAT traffic which can collide with commands from a PC, that can result in very strange behaviour.

We have not had other reports of incorrect CAT control, as you describe, of the IC-7300 with WSJT-X v2.4.0. Are you using the built in Hamlib library for direct CAT control or one of the other proxy CAT control methods?

When changing the TX offset frequency enough to require a change in the split frequency occasionally the base frequency will change.  It does not happen each time but the effect is cumulative.  For example:
Gene:

You haven't said how you're implementing the CAT control of the 7300 but if it's CI-V via the 7300's USB port then you'll need to ensure that there's no RF getting into the USB connection - that can cause all sorts of random and intermittent errors on the USB bus.  Do you have any ferrites on the USB cable between the PC and the 7300?

Also, have you tried using the 'Fake It' option for split, to see if that makes any difference?

FWIW, I very occasionally saw a similar effect on my 7610 (when using 'Fake It' split mode) - the rig's frequency wouldn't always return to the correct 'base frequency' after the end of a Tx period, it would stay on the frequency selected at the start of the Tx period.  I changed the configuration of the ferrites on the USB connection between PC and rig, to put a more substantial common-mode choke at the PC end of the USB cable, and haven't seen the effect since.

Makes no difference. Out of curiosity how would this effect the commands WSJT-X is sending out and how would this make the rig change frequency when there is no other equipment on the chain?

For general HF work I choose to call CQ in the time slot with the strongest signals.
There is a benefit to having all the RX signals near the same level without one or more big signals in your RX.

- Choose 10m from the drop down box -
500             28074       28069.50

As a WAG rather than sending a "set frequency to X, set split to Y" the software is sending "increase/decrease split by Z" but occasionally sends the "decrease by Z" to the base frequency rather than the split.  Choosing the band again in the drop down box appears to send a full "set frequency to X, set split to Y" command and everything goes back to where it should.  Until the TX offset is changed again.

There will always be a frequency change, as the frequencies of the FT4 'areas' are different from the FT8 areas.   As far as why its missing, have you tied doing a Frequency List reset?

Go into Settings -> Frequencies and RIGHT click in the list, from the menu select RESET.    You should then see a 20m FT4 frequency.

Hi Jack,

FT8 and FT4 use different transmit periods so are not compatible, they are used in different frequency sub-bands. The WSJT-X "Settings->Frequencies->Working Frequencies" table defines the frequencies offered on the main window pop up list, they can be mode and region specific. If you have upgraded from an older version of WSJT-X you probably need to reset the list to the current defaults (right-click the table body and press the "Reset ..." button in the contextual pop up menu that appears.

Bill -

Thanks for the input. The sound card has analog audio out (of course) but I don't know how much, if any amplification, it has. 

I modified my settings by decreasing the KX3 mic gain to 10, and raising the WSJT-x pwr to -15db (sound card still at -8db). Monitoring both the WSJT output and the sound card output with  headphones I hear a clear warble moderately loud. Operating in these conditions appear to give me more frequent QSOs. The signal reports haven't changed, but maybe my signal is now easier to decode at the receiving end?

Apologies if this has been asked before.

I have one copy open for my IC-9700 on VHF/UHF and the other for HF on my IC-7300.

I use the call roster on GridTracker and when I double click on a station it populates the correct copy of WSJT-X and if the station is calling CQ then it toggles Enable-TX to on.

However, particularly if it is an HF link from GT and if I am already in Enable-TX on VHF then the Enable-TX is toggled to off on the VHF copy as the HF is turned on.

I am guessing that this is something that GridtRcaker might be "doing/causing" inadvertantly?

Thanks in advance - Terry
Hi Terry,

you can diagnose which end the problem lies by using the test application message_aggregator that ships with WSJT-X. Run that with two instances of WSJT-X and use it to initiate QSOs to see if there is an cross "interference" between WSJT-X instances.

Bill,

Yes - I knew about the release of WSJT-X V2.5.0-rc5 but as I'm not very good with computers thought that I'd leave it to much better beta testers first.

I will continue to run the old Map65 on the old HP notebook / FCR Pro+ combination for the time being then re-visit in a few weeks time.

I've sorted out the screen issue by hooking the notebook upto an old 21" monitor!

It was just that the symptons were  (and still are) very puzzling.

Is it possible you (un)plugged a USB device, (dis)connected a Remote Desktop connection, (had Windows automatically and without warning) do a Windows Update, or something else?

It might be useful to iterate through all your USB devices, hubs, and connections with Device Manager and disable any power saving settings.

Is there a memory leakage somewhere along the line. Keep an eye on the amount of memory WSJT-X is using. If it is slowly climbing up, sooner or later it will crash. How long depends on what else you have running at the time and how much memory you have fitted in your PC.

 

That said it might not be a fault condition. If the software is keeping a list of events (such as decodes) this will also slowly build up the amount of memory used.
