[Elecraft] K3 TCXO

[Don Wilhelm]

  Kjeld,

It should be listed on your invoice.
If the paperwork with your K3 included a calibration data chart, you 
have the KTCXO3-1 - there is no calibration data chart for the stock TCXO.

If you have misplaced your invoice and/or calibration data sheet, an 
email to sales at elecraft.com may be able to obtain a copy of those 
documents - I recall that the calibration data was being kept on file.

Other than that, you could physically remove it to check the numbers on 
the TCXO can.

73,
