Waterfall not responding or appearing on refurbished iPad Pro

Richard Everett

I just received a refurbished iPad Pro (2015) from DirecTV's protection plan to replace my iPad that they failed to repair after numerous attempts.  Now...my SmartSDR is not showing a waterfall, (hide waterfall is not enabled) and is stuck on a 20m screen even if I'm on 40m.  Frequencies do not change on the missing waterfall as seen in the attached picture.  I've tried reinstalling the app, (it downloads from the cloud and I don't know how to change the cloud version of the app), but the problem does not go away.   HELP!

My reply applies more to Richard's OP.  Your's is different as you explained.  I would delete (uninstall) the Smart SDR for iOS app, reboot your iPad, then re-install the app.  If that fails, contact the author, Marcus, directly via email.  He responds readily.

Greg, my settings does not have a low band connection option under Communications or anywhere in the settings sections.  Thanks for attempting to help.....I looked throughout the app for a low band connection setting and can't seem to find anything like that.

I found the problem!  I finally found the low bandwidth connection button under Show Extended Settings, (bottom right under General Tab).  Once in Extended SettingsI found the Low Bandwidth button but it was not on.  I also saw a button that is Force Network MTU that was on.  I slid that o er to off and voila....it worked!   I hope this helps you Dave.   Thanks Greg!!

I think my instructions were for an earlier version of Smart SDR for iOS.  Marcus must have moved the control.  I haven't had to access it in a long time, so I never noticed the change.  Glad you got it figured out.  Good catch on changing the Force Network MTU.  I originally got the tip on the Low Bandwidth issue from Marcus himself after I had reported that my app was always starting on 20M.  Emailing him on seemingly bizarre problems almost always yields a response with a solution.  You have to remember that Marcus is the one who supports the software, not Flex.

Thanks Greg!
