Problem with WWV frequency testing

While checking Auto Frequency check, I go to Band, WWV, go to 10Mhz, settings, Radio Setup, RX, then press start.  It goes thru the procedure and gives me a reading.  Upon completion, I go to another band such as 40M.  That works OK but if I go to 30M, it goes back to 10Mhz. Where is my 30M band? Am I doing something wrong.
Using latest software and Win 10

No, you have inadvertently "trained" band persistence for 30m to go to 10.0 MHz.

When doing a calibration, it is not necessary to tune the slice to the WWV frequency.  Regardless of what frequency Slice A is on, just open the calibration window, select the WWV (or CHU) frequency, and run the calibration.  Once it is done, it will change the frequency of Slice A back to where it was before you ran the calibration and not save the frequency in the band persistence database.

You need to clear band persistence to fix this.  To do that, export your profiles, check Select All but then uncheck the Preferences.  After the export, do a factory reset on your radio (the instructions are in the software and hardware manuals and differ by radio).  The Import the profiles you just exported.  This procedure will reset your band persistence.

Tim,  That solved the problem.  I was using it to prepare for the ARRL FMT and I was satisfied with my results.   Thanks as always for the advice

When I do a calibration it sets offset to -6128.  This seems like a lot.  Looking around some of the posts looks like the normal is around 300.  roger

A correction value of -6128 ppb is within spec and I presume the radio is on frequency so I wouldn't worry too much about it .
