SmartSDR Profile autosave causes  record playback distortion

more info please so we can test

SmartSDR profile autosave feature added the "DAX on" setting to my daily SSB 40M Net profile. 

I am running a Flex 6600 on SmartSDR Version 2.6.1. 

While talking on the net I was asked to record and playback another stations audio. On playback, several stations commented that my playback audio had distortion that was not in the original stations audio. After checking all my settings I found the my profile, for this net, now included the DAX setting for my SSB profile on 40M. 

There are 2 problems here;

1)  There should be a way to disable the autosave problem in the Flex SmartSDR Profiles. If I establish a profile it should never change unless I change it. 

2) The DAX setting should not distort the audio of the recorder playback. Both the slice DAX and the IQ DAX were set to "None".

I was using the PTT control to do the recorder playback. The received audio sounded good locally during playback, and was only distorted to the listening stations on transmit.

I had all of this information in the original problem but it was not included.

Interesting, I don't know why Dax is in the mix unless you set it that way. Auto save only saves changes you make. Set everything like you want it and simply re save the profile and the settings will stay the same, unless you change something. Just for info, Flex is aware of peoples needs for Auto Save to work differently than it is now.

This auto save feature gets me all the time with turning DAX on and where I run Remote it mutes the PC MIC and I have to watch that very close.
What I do is use Memories to set things up so when I go to FT8 or other Digital mode I have a memory for each mode and  band and for my SSB nets I have memories for those and this keeps me out of trouble MOST of the time. 

Below is my OPINION only and not bashing on anyone
For me the way AUTO Saving the profiles works is **** if they want to Auto save to the "Default" profile that is fine but they should RESPECT my settings and not Auto Save to the Profiles I have made that are named different then the "Default" Profile OR LET US LOCK OUR PROFILES other wise this defeats the main purpose of the Owners profiles,
Again this is just MY opinion.

I just tried recording myself, with each of the 3 DAX selectors, on one at a time and heard no distortion in the recording playback.
I will try this on the air later today to verify.

Tom,,you can hear yourself on the air by listening to you TX with the FDX feature. What you hear there is what everyone else hears. Do you know how to set that up?

ai6re

You are correct. There is no distortion locally. Only the transmitted signal from the playback is distorted on my Flex.

ai6re

I totally agree.

ctate243

this is interesting.  have you tried restarting everything?

ai6re

The circumvention to the playback distortion is just turn off DAX transmit and re-save the SSB Profile. The fix for Profile autosave, is to move back to Ver 2.4.0 or earlier where Profiles did not change without your knowledge.  

ctate243

wow you may have found a bug..  If you can recreate this and put some additional context around this I would be happy to submit it for investigation by the programming team.  may be a good catch.

ctate243

its also to understand that profiles are not persistent, and changes to them are.  So if you load a profile its in the state you loaded.. if you make changes to settings post profile load, there will remain persistent. but if you reload the profile, they will be in the state you saved them in.

ai6re

Unless you export your profiles the changes you make in the Xmit area are auto saved and modify your profile. Only profiles exported out of the Flex application are safe and remain as originally externally saved. 

The newest version of SmartSDR does not fix this profile problem error and it appears Flex is no longer making improvements base on the Flex user requests. 

Bill -VA3WTB

ai6re. It seems your not understanding what just happened. This last maintenance release was a critical state release. It was critical that those things were address as soon as possible. This does not in any way suggest Flex is not interested in the user base request. This needed to be taken care of before any other things can be fixed.

Flex-6400, and Smart SDR 3.3.33 and other previous ones the problem is the same.

When playing back recorded audio it is extremely distorted. The transmission volume is too high.

Reboots of both computer and or radio do not resolve the problem, and if your listening locally it sounds fine, but over the air playback is extremely poor.

On other computers the same happens, even the software installed for the 1st time.

Nothing like when has been recorded. Uninstalling and re installing DAX driver’s dose not resolve issue either.

I already opened a ticket

I have noticed the same problem with played back audio. Others report it is very distorted. I then shutdown and power off my Flex6600, and restart SmartSDR. This appears to temporarily fix the problem, for a short time, but it does come back and I have no idea what causes this. I have seen this problem across several release levels. I am also running 3.3.33.

A workaround that may help is to use FRstack memories, which stay the same, unlike the flex profiles. In addition the memories store many more parameters than the profiles. This auto save is a sore point with flex. I talked with Steve Hicks about it at Hamvention. His response was a terse “We got it”.

Dan Trainor

I want the ability to lock my profiles such that they cannot be changed by the application or another user. I also want to turn off this auto-save. I never gave permission for application to automatically save changes that I don't want to make persistent. I hope this bug is fixed in next release.
