TX and RX Frequency Difference #40m

Ernie Bailey - N2DGQ

I have just completed my QCX Mini Build for 40M.  The RX and TX Freq seem to be off by about 80Hz.  For example, I TX on 7.115.20 and RBN says I'm at 7116.00.  The delta is consistent no matter where I go on the band.  Do I need to tweak the reference frequency or is this normal operation for the QCX Mini's?

Thank you in advance for your helpful feedback.
