[Elecraft] [DXLab] Mode not Switching with band change?

[Dave AA6YQ]

+ AA6YQ comments below

I am running an Elecraft K3 and a KPA1500 amplifier. I use the DXLab Suite of programs for logging, rig control and so on.

If I do a manual band change on either the K3 or using the KPA1500 and change back and forth between 15m and 40m, the side band changes appropriately.

If I do it using the Commander Bandspread window buttons and go from 15 to 40, it stays in USB.  I can then do a MODE ALT to get the correct mode, but it doesn't stick if I go back and forth.

FWIW, going to 80 has the same issue...

+ "Changing frequency via the Bandspread window"

+ "Commander remembers the last 5 frequencies you visited on each band, and the mode in use for each such visit; this information is stored in a Band Stack associated with each band. If you QSY the radio, and then let it remain on a frequency for longer than the dwell time setting, the new frequency and mode will be saved on the appropriate Band Stack. The Bandspread window's Band panel contains a button for each band between 160m and 33cm. Clicking a band button sets the radio's frequency to the most recent frequency used on that band, sets its mode to the mode in use at that time, and clears Split; the Band Stack is then advanced, so that clicking the same band button a second time sets the frequency/mode to the next-most-recent frequency/mode used on that band. Using this mechanism, you can QSY to the most recent 5 frequencies."
