AA6KL,
Thanks for the info and tips, I was successful in clearing the config and saving the cleared config to slot 0. Re-calibrated the device, and there was still no change with the smith chart above 300 mhz.
Firmware verison 0.1.1 is fine above 300 mhz, and anything above 0.1.1 causes the issue. So i still going back on the firmware is the issue (at least on my device).
