Jacob, You can do the alignment just fine. If it is mostly dial calibration and filter alignment that concern you, take a look at the K2 Dial Calibration article on my website www.w3fpr.com - that article also covers the filter alignment. If you do not have Spectrogram or some other audio spectrum analyzer, download it and use it to give you the easiest method of determining your actual filter width, shape and its positioning in the IF passband.
If the pitch shift continues after the filter alignment, then there may be something stuck in the EEPROM - clearing it may require a Master Reset - but before you do that, download the A to B upgrade instructions from the Elecraft website because it contains a nice set of labeled blanks where you can record your menu settings. Record ALL the menu settings before doing the Master Reset and restore them afterward. The reset puts your filters and everything else back to the defaults. If you want to do a complete alignment of that K2, you may want to download the extract of the K2 manual that I have on my website too - it is the Rev E manual with the assembly steps removed leaving the alignment information intact. Note that the manual instructions will give you workable filters, but they are not optimized - use the instructions in the Dial Calibration article to optimize the filters. 73, Don W3FPR On 11/15/2011 2:13 PM, jacob chambers wrote: > Hello; > > While I am generally thrilled with my new K2 (not built by me) I feel she is > in need of an alignment touch-up.
