Not unusual in that the radio likely never worked from the day it was
assembled. I've seen that a few times on the Heath gear I've worked on.

Subject: [Heath] Problems with HW-101 - a possible solution

Hello again, Gang:

At the suggestion of another list member, I checked the position of the
notches in the 
bandswitch wafers.

Of the 5 wafers, three are completely backwards. The only 2 which are
correct are the final 
tank coil section, and the heterodyne oscillator crystal section.

What I cannot figure out is why, given this situation, that 80, 40, and
(sort of) 20 worked at all.

But, I'm not going to bother to figure that out.

After I have corrected this problem, we'll see what is left.

Thanks to all.

Ken W7EKB
