Band selection not working on 40m and 160m only

Dave N2OA

Last night I was switching bands and noticed that I could not directly select the 40m or the 160m bands. I could select all other bands without issue.

I came across this twice before since November 2018 and assumed since I had

found a post in the forum about the issue and corrective action that it was being addressed in the software. I had the same issue last night in the ver. 3 software so I guess whatever is causing this has not been resolved.

I understand that the current fix is to do a reset on the radio and that worked fine but hopefully the developers are aware of the issue and working to resolve it.

You have expanded the pan adapter  spectrum settings beyond to  band limits (I assume 40), the band memory has stored your settings. 

Compress the pan adapter range down until you see only 40 meters on the pan-adapter.  Switch to another band then come back to 40 meters, you should now work as you desire.  Same for 160.  I have done this to.  The first time I did it, it took a long time to get the radio retrained

Happened to me once several months ago. A remove power and re-start fixed it. Never happened again.

I never expanded the range beyond the bands, especially  by any large measure. After discovering the issue I did try to narrow each band to just a small segment, maybe 50 KHz on 40m and 160m and the issue still continued. Regardless , SSDR should know the bands and I shouldn't be able to mangle that setting. After all it's the band switch, not a band "memory"

The Flex has a feature that is called persistence, which remembers  the settings  band to band.  When you hit the band button the persistence feature is taking you to the previous settings.  Somehow the band data in the persistence memory was corrupted . The SSDR manual  tells you how to clear the persistence. ( Craig's fix) .  

I **** mine up by expanding the panadapter looking for interference that was coming from out of band and then not narrowing things back down before leaving, the Flex remembered that and took me back to a 10 MHz wide panadapter.  I got the radio back with out the reset but it was a pain.
