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 [email protected] 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, Don W3FPR On 7/18/2011 7:06 AM, Kjeld Holm wrote: > Hello all, > > A simple question I hope: How do I see whether my K3 has the KTCXO3-1 High > Stability Reference Oscillator installed or not? > > I believe I ordered this add-on for my factory built K3 but now I am not > sure. > > Thank you in advance. > > OZ1CCM, Kjeld > ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
