Memories and Most Recently Used Frequency Utility

I have spent countless hours enjoying my Flex-6500. To improve my operating
proficiency I have written a utility to track my most recently used frequencies and save frequently used frequencies for easy recall. I have successfully used the utility with 1.3.0 and 1.3.8 versions of Flex Radio’s SmartSDR.

The utility is called FRStack and I am releasing a beta version of this utility for your review and enjoyment. If you wish to report an issue or suggest an improvement use the utility’s Help Menu Contact Support link.

You can start FRStack before or after you start SmartSDR. FRStack does not require CAT.  Slices appear and disappear in FRStack as they are created and destroyed in SmartSDR. You can also swap Slice settings with another slice which helps when logging QSOs which are typically logged against Slice A.

I have tested FRStack using a Flex-6500 but it was written to also support the Flex-6300 and Flex-6700.!914&authkey=!AOBrxzxCvgXMTYw&ithint=file%2cexe
