Except for a few rigs with a built in frequency counter, I haven't found ANY 
rig that's on its indicated frequency. Most rigs are within 7-10 ppm, a few 
have been within 2-3 ppm, but they have all been more or less "off." 

I don't have a "professional" counter but my ears say the crystal calibrator 
is within 2 Hz of WWV at 10 mHz, the B&K I do have says the calibrator is 
dead on, and that all three of my VI's, one plus and two option 3's, are rock 
solid and within perhaps 30 Hz of the indicated transmit frequency. 

Of course, besides the direct method of transmitting and checking the 
frequency, you can hook a counter up to the speaker, tune in WWV in CW mode, 
and check the audio frequency over time. This is a pretty solid check of 
receive frequency stability as well.  

I sure wish Izzy had gone some other way. I'd be at the 'fest.
