Default hallicrafters s-40a, bad band(s)

I believe your antenna coil is open...Look at schematic and find
BC band coil,check continuity from ant post to ground... coil is
probably open..This sometimes happens when lightning sends a surge via
an external antenna,burns out the ant coil on the band that is selected
at the time..You may be able to repair the coil if that is the
problem...GL HS

again. i guess what i don't get is how i can get a nice signal thru
w/the gen -- tune the test signal and its images, but not tune
stations. i don't have a whole lot of experience w/this.

First, carefully clean the band switch wafer metal wipers with a cotton
Q-tip and some DeOxit.
No need for heavy handiness here -- just good patient (methodical) cleaning.
IF you are short on time or not patient that day -- do something else and
come back to it.

Perhaps you are simply trying to receive stations on bands for which
there is poor propagation during that particular time of day....
