[Hammarlund] SP-600 alignment

[wb3fau55 at neo.rr.com]

Folks, i have an older SP-600 here i am trying to do tracking
alignment. i have it working well on the lower 3 bands-[single
conversion] . On 7.4 to 14mc, the tracking is too wide- about 300 kc
at top end. On 14 to 29mc, the is an error of 900 kc, which i cannot
narrow. is the error in the 2nd conversion or bad parts in 6C4 osc?
thanks for any advice Russ wb3fau.
