<---Who made the xtal for you? Sounds like the load capacitance is off but it could be caused by other factors as well. Remember that the xtal frequency is much lower than the resultant 2 meter frequency (maybe as much as 1/12). Since your freq is only off by 20 Khz, 20 Khz/ 12 = 1.6666 Khz. As you might see, this error is easily caused by the wrong load capacitance. Either they built the crystal wrong or your transmitter was modified (more than likely by a previous owner, attempted to pull a "too high" xtal on channel perhaps?). If you have the schematic, I'd look closely at the oscillator....
