[Milsurplus] Command Sets selectivity video ?

[Hubert Miller]

Wayne, big thanks !!! This is it. I had thought that 'selectivity' would appear somewhere in the title so I had not viewed this one.
at 24:45 begins the crystal filter segment I was interested in, along with a schematic, great! answers my question about the filter.
What got me to thinking about this video again, was I recently pulled a bunch of 2 MHz band crystals out of a couple boat radios
I sold.
thanks again – saved me a bunch of searching!
This is a most interesting video, I think. I tried the regenerative IF trick a few decades back and was entirely dissatisfied with it,
so the other alternatives are interesting.

Oh, sorry, I thought that was the problem.  But I do think that I've also seen that one with the 3 RX on the table. Now if I could just remember when & where.

Are you sure it wasn't this video:
