2 meter display frequency is off just a bit

I've noticed that all simplex and repeater frequencies are off just a bit.  As an example our 146.94 repeater is actually on 146.942.  Every station or repeater I've come across on 2 meters is off by about the same amount.  They are all just a tad high on my display frequency.  I know I can use RIT but that's not really correcting the problem.

Is there a way to adjust this?  I've gone into Setup and run the "Frequency Offset" application while having it pointed to 15 Mhz but that didn't do anything to adjust the offset for 2 meters.

Is anyone else noticing this?

    Maybe, recalibrate using the the repeater's frequency instead of 15 mHz? if your positive the repeaters accurately calibrated.

    Are you going by the bar display on the pan, or by tuning the carrier dead center in the slice flag and reading the frequency readout?  Since I only have a 6500 I am not sure how 2 meters reads out on a 6700.

    That didn't work.  I don't think it calibrated off of the repeater.

    I zoom in on the panadapter then center the slice on the carrier and read the frequency readout.   Its really noticeable on SSB.

    I have added this to our bug tracker for further investigation.

    Do you have a GPSDO?  If I didn't, I would have thought the same when listening to FM, but it is amazing how off everything is.  But FM is pretty tolerant.  We actually now use my 6700 to keep the local repeater systems in alignment.

    I saw the same thing last night; however, right now it seems dead on for 2m FM.  Not sure what changed.  Nothing on purpose on my part.

    Am enjoying monitoring the local repeater while at the same time operating 20 CW on another panadapter.  Great stuff!!

    Has there been any progress in this area?   I've been using my 6700 on 2m SSB lately.   There was a group of us on 144.220 USB this morning.  I have to put my VFO on 144.220.300 so that I'm on frequency for everyone else to receive me clearly.  Then I have to use RIT to further adjust my receiver to approximately 144.220.600 in order to receive everyone at my end clearly.  This is also the case on FM

    I use my Kenwood, or my Icom radios and they are both spot on frequency.

    I've been waiting for well over a year now to get this addressed.  I think I've been pretty patient......

    Does anyone else with a 6700 have this problem?  Maybe there is a way to calibrate the 2m band with the 6700 that I'm not aware of?

    I've added 2m to my 6300.  There is a box in the xvtr setup for an offset adjustment.  I used my sig gen to adjust for zero offset.  I know the sig gen is right on.  Simplex stations and repeaters are often off by a 100 Hz or more.

    I have the 6700.   I actually have 2M listed under the normal band selection.  If I go into the XVTR tab of the Radio Setup, it has no effect on the 2m band.

    Anyone from Flex care to shed some light on this?  I have a 6700 and I'd really like to know how to set the transmit and receive frequency on 2M to a reference frequency.   My display frequency is quite a ways off on both transmit and receive.
