Which parts of the alignment do you wish to do with a scope? I found it useful only for the final alignment of the LC filters in transmit mode because I don't have a sensitive QRP-level wattmeter. I used a modest old scope (Tek 2215) with a 10X probe, a BNC tee, and a good dummy load (Bird TermaLine). The rest of the alignment can be done adequately with just a DMM and the prescribed methods of the K2 manual, but filter alignment and BFO settings can be improved upon by using Spectrogram or any other audio spectrum analysis tool - there are lots of postings on this issue in the forum archives. I ran my K2 very happily for 4 years after using only the K2 manual's procedures for alignment, then re-did them last summer with Spectrogram. I can't claim any dramatic performance improvements except that I could see where the filter passbands were actually located.
