The alignment instructions in the manuals for the two HRO receivers I have
were quite good, so I won't re-invent the wheel here. That's what I used.
If you can't get the exact manual (got both mine off BAMA) for your model
HRO, alignment instructions for any of the single-conversion (I THINK
pre-HRO-60) HROs should be close enough, if not identical. Carl can chime
in, he is more experienced & knowledgeable about this than I.

Carl, I'll respond to your serial# question when I have the time to grab
it (I'm at work, and the HRO is home - of course.)
