frequent spontaneous mode change from usb to lsb

Frequently when I change bands in ssdr I find lsb mode selected even though I have not been in any band that would use LSB.  In fact, I almost always an in USB.
Not a big deal, just an aggravation to have to change modes.

When you change bands, the current slice is destroyed and a new slice is created.  If it is created on a band less than 60m, then the default mode will be LSB.

The only variance to this is if you had created/used a slice on that band and its persistence information was remembered.

Thanks Tim,
I rarely go below 20m. 99% from 10m to 20m.

Then I suspect you have some confusion in the band/slice persistence database.

You can reset this by doing an export of your global and TX profiles, doing a reset to factory defaults and the importing only your Global and TX profiles (only select those two options).

I did what you suggested and all seemed well for a while but this afternoon when I opened a new band once it was in LSB and later another band opened in CW.  I have definitely not set those mode in any band since the reset yesterday.

There are default setting if you create a new slice in a band where there has never had one created before.  The mode should sync up with the band plan for that band based on the initial frequency the slice is created at assuming nothing external is instructing the radio to do something different.

Is your logging dxspotter changing it?

I don't think so.  It happens when the band is changed before I go to a frequency.  Dxspotter is not involved.
