I have a Flex 6300    Version 1.5 does not seem to autocalibrate well.  Using Fldigi and the previous Flex radio software calibration routines my calibration for correct frequency is approx. +450 offset.   With the current 1.5 version it is -1200.   That's is absolutely not correct. I use Fldigi and other to check the flex.   Not sure why this version centers on the incorrect offset.  Its easy to tell if the auto calibration is in the "ballpark".   switch between USB and LSB on 15 MHZ...if you detect a difference in tone...you are off calibration.  thanks   Bruce N0JX

We have reproduced the issue and determined root cause for the FLEX-6300 calibration problem and as assumed, it only effects the FLEX-6300.  It is not related to the transmit distortion issue; that investigation is ongoing.  It was related to a situation where initial test conditions were not set properly under certain circumstances causing an error in the calculations.

The FLEX-6300 frequency calibration fix will be included in the next release of SmartSDR.  Sorry for the inconvenience.
