Unwanted auto change of operating mode

Glenn Depp

Flex 6600 changes its operating mode automatically which is causing issues.  While utilizing Software ALE the flex continuously changes to the normal operating mode for voice, even when it is not desired.  I am using MMI commands to control the radio and even when it is the appropriate command for USB the radio automatically overrides the commands and switches to LSB which makes ALE not possible in the lower bands.  Any known corrective actions for this???

ZZMD also no joy..  I did have some code on previous install that inserted a pause and the the mode change, it worked but don't remember how it was written and don't have the file anymore..

Send the mode command after changing the frequency.,

I have now changed the MMI and placed the MD2 at the end, I also tried the ZZMD2 at the end, also tried making the 2 into a 02.  None of those make any difference.  It simply will not change to USB without me selecting USB in the SmartSDR which does nothing when scanning in ALE as it just reverts right back.

Please provide an example of the exact commands you are sending when you change to a different ALE frequency.  I want to test it.

For starters, SB0; is not a supported CAT command for the FLEX-6000.

Second, are you executing these commands as a single string?  That may be part of the problem as the parser may not be able to split up the string into separate commands.

Third, the MD2 command is missing the command terminator (;)

And last, I do not know if you can add a wait or a pause between issuing the commands or not, but if you can, that would be preferred.  Some CAT commands will return a value, especially if the command syntax is wrong or the command is not supported (?;).

I ran the command string that you provided and all of the commands ran successfully except for SB0; which returned a ?; since it was not supported.

I removed the SB0 command.  I searched in the Kenwood files myself and couldn't find there.  Not sure why he built that into the MMI for me.  The MD2 did or rather does, I must have either not copied it or deleted it on accident.  Even with that deleted I have same results, I am at a loss.
I am only scanning 2 channels per slice so I can have a pause, I am not sure how to enter that.  I also am not sure how to enter on multiple lines.  But this 4Mhz freq is not the only one that has issues, there is a 6Mhz channel that does the same thing, very close to the ham bands where the flex automatically changes the mode from upper to lower.  If that was able to be shut off I bet there would be no issues with scanning ALE right next to the Amateur Bands..

You're making progress.

If you only have one slice open, you can forgo using the FR0; command since you only have one slice and it is always the active slice.

I was using 3 MARS ALE on 3 slices, only 2 frequencies on each.  But now that I am scanning on the Slice 2 with this odd freq issue, I have a click occurring when scanning on 3rd slice.  So I am not sure what I will do.  I don't like the clicking going on in the radio.  I know what it is just don't like a click or two every second or so.  I do not want to wear anything out.
Also, the switch from LSB to USB does not happen each time.  Sometimes it stays in LSB and switch over on the next one or two scans of that frequency.  Not very consistent.  I VERY much look forward to an internal ALE controller, as well as a M110A modem.  That would be very excellent.  One day.
