0.6 Mhz. I recently aligned a HQ145 and the frequency for the BC band is 0.6 Mhz.

Hi all,
Has anyone got detailed and correct info on
aligning a Hammarlund HQ100? The admittedly
poor copy I have seems to advise tuning the RF
input transformer T1 at 6 mHz, which is impossible...
it's the BC band.
Maybe a decimal disappeared on this print?
Hopefully,
Nelson
