ALE operations incorrectly switch to LSB on 40M ?

Glenn Depp

This issue still exists today.  I have made MMI Commands, tried the USB-D, and occasionally it will land on LSB then switch.  This delay makes those frequencies about useless.  If anyone has any example MMI commands that would be very appreciated.  I wish there were an option in the SDR Software that you can TURN OFF automatic band mode settings.  This would be very useful.

My issue with that response from Flex is NOT ALL USE BELOW 10MHZ IS LOWER SIDE BAND.  All digital modes should be operated in UPPER SIDE BAND, not LOWER.  This automatic changing should have a way to disable by the end user.  And its not just an inconvenience for MARS Operations, its ALL ALE and DIGITAL MODES.  Very sad..  Well we shall see if they can make what I consider a simple change, add a disable/enable to auto changes due to selected band.  I really hope the requirement for LSB on lower frequencies simply go away as there is no reason to do that, no other service uses LSB on HF other than Amateur and a few splinter channels by federal services.

Andrew are you using the PCALE software or something else?

Glenn, this issue has been identified for a long time.  The problem is that most digital mode programs issue a mode command after changing the frequency.  PCALE does not.  Their developers were informed of this 3 years ago and have yet to change their software. Everyone I have helped with this issue, I have asked them to contact the developers to make this change in the software.  Until they do, this issue will exist.

If you see my older post above I was able to get it to work by writing an MMI file that sent a mode command along with each frequency change. I believe that with MARS-ALE radio control will be transitioning over to users writing MMI files for radio control, vs. built in radio selection but I may not be understanding that correctly.

And... in the same test build area on the Groups io page, there is a new "Fix for Automatic LSB mode selection in FLEX radios during ALE scanning" -- now THAT IS exciting news! I think this new fix has been incorporated into the recent updated FLEX6000 build I mentioned above.
