Problem w/Slicemaster 10.5d and WSJT-X

I am finding that when using Slicemaster 0.10.5d with WSJT-X that it periodically introduces a "hiccup" into my FT8 transmitted signal.  I have had to discontinue using the software (SM) pending resolution.  Anyone know about this?

I get hiccups and I'm not using slice master.

I do not get hiccups in my transmitted signal absent the use of Slicemaster, or so it at least appears.  I would feel bad if I were wrong about the cause because I wouldn't want to wrongly bad-mouth the software, but the problem does seem quite reproduceable.

Roger,

Dont think of it as bad-mouthing.... think of it as reporting a bug.  In this case I'm not (yet?) convinced that it's a Slice Master bug but I do appreciate comments from anyone who is using the software and having trouble with it.  A primary goal of Slice Master is to solve problems with configurations.  That it happens to provide a few features of it's own is secondary.

There have been reports of receive audio problems when using Slice Master.  So far nobody else has mentioned TX audio issues.  The problems I've seen reported were on the analog side and didnt seem to involve DAX.  What you are seeing could be related, though it does feel a bit different.

The receive audio issues are related to a bug in the radio that causes the audio to break up if their is too much API activity in a very short amount of time.  Sending spot updates to the radio fits this description.  I've mitigated the problem a bit by slowing down the updates.  

You could test the hypothesis that this is a TX problem too by turning off all spot sources in Slice Master (including internal) and giving it another try.  Without Slice Master sending spots to the radio, the connection between WSJT-X and the radio is quite similar to how it would work without Slice Master.

I've seen random hiccups in WSJT-X, but I never connected them to Slicemaster.  I'll have to keep a closer watch.  I DO have a related problem, however.  Since letting Slice Master start WSJT-X, JT-Alert no longer works, and I get an error message related to the UDP port.  Any ideas how to cure that, Don?

Thanks,
Rick, W0FG

Rick,

The way I suggest working with JTAlert is to launch as many as you might need then just minimize them.  When Slice Master launches WSJT-X, an available JTAlert instance should notice it, pop-up, and attach to it.  As far as I can tell, JTAlert has no configuration options that get in the way of this.  It uses it's own form of magic.

When I started the WSJT-X integration I also built in support for JTAlert.  I had to remove that support because of bug in JTAlert that would cause multiple instance latch onto the same WSJT-X instance.  The method I suggested above is a compromise but seems to work.  

If this hint doesnt help much, feel free to send me an email with a screen shot of the error you are seeing.  I'd be happy to take a look.

I launch JTAlert first, ahead of everything, even SmartSDR, in fact I have JTAlert launching SmartSDR, I also have it opening DXlabs Launcher, which opens Slicemaster, and other things.I have Slicemaster opening WSJT-X whenever that Slice is running. JTAlert will just wait till it opens and attach to it. I get the added benefit of having all the apps that JTAlerts opens, Auto closing whenever JTAlert is closed.
