Hi Gang,

I thought I was performing a quick freq alignment of a 959b but not so fast.  The alignment instructions have you set it on channel 1.  The issue is that if I align the SSB TX on 1 it is 500 HZ off on 40 or the same if I align on 40.  If I align on 19 it is about 250 HZ off on 1 and 40.  Ant thoughts about why the alignment would not have a linear outcome?  AM seems to be only about a 25 HZ difference.


Thanks as always!!!
