Running Yaesu FT-100 100 Watts no amplifier using an MFJ-993B Auto Tuner.
I notice a difference in the frequency the rig reports and the tuner.
For example: transmitting USB on 14.280.000 (rig) shows as 14.281
Now if I set the freq to 14.279.30 and transmit voice on USB the MFJ tuner shows 14.280
This differential happens on all freqs and all modes including digital irregardless of power settings.
I'm not having any issue with my qso's and the reports I get are almost always good so I'm wondering if I should be worrying about anything.
