What temperature do you keep your lab/room at? I see the standard lab reference temp is 68 degrees F. Im finding that when i align cb radios at this temp, when they get to their home either base or mobile, people have the house alot warmer right, 75 - 80 deg F, and waaay warmer in mobiles. And as a result the frequency slides off a bit. Hf rigs, test equipment etc no problems, spot on. Its just the cb radios that are all over the place with different temps.
