[Elecraft] used K2 Alignment

The high bands may be difficult to pre-align without a signal generator.  I speak from experience from building SN 7105.  I thought I had something wrong with my soldering when I discovered the rig deaf and dumb on 10 and 12 meters when all it was was a poor job of alignment using atmospheric noise.  A friend who had a signal generator helped me discover that the soldering was fine, I just had not peaked the bandpass filters on alignment.  He had a signal generator to help me do a first pass alignment.  I obtained an XG3 and realigned the entire bandpass filter section and also aligned the S-meter for S9 at 50 microvolts.  It can be done with sensitive ears but it is iffy.
 
Others can voice their opinion but I found the XG3 to be a worthwhile tool to have.

The rig used to have all the bells and whistles but now is CW only with no tuner, SSB, etc. It is pretty much on with alignment but not exactly. The one thing that definately bothers me is one filter width - 700hz - causes the received signal to change in pitch. The other settings leave it unchanged. Also, I'm never on a "cardinal" freq when I work people - and I'm sure some of them are on whole frequencies - like 7.030.0 or 14.050.5. I'd like to get this thing closer. How best to proceed?
