Do you actually have oscillation? You have a scope, see if you do.
How about the switch connection do you have it?
Does this "no signal without scope" happen in all bands? Or just in one? If in all, this shows to more common cause.
PS. THinking about it, it seems to point to the packet switch - somehow not being well connected to that 4th grid.
A Stupid question - did you make sure the trap filter coil (is it?) #2 in series with antenna is intact?
