[R-390] A vs non A

[Roger Ruszkowski]

Fellows,

Sweeping did come along about 1971.

It is not in the manuals.

At best there was a study guide not even a real TM publication
on how to set up the test equipment and do an alignment.

We also had a frequency counter to adjust the end points 
on the VFO and to set the BFO, we also used that to
set the AN/URM 25 output frequency. The counter is
not in the TM either.

The sweep generator and frequency counters helped.

More toys is always good. Not required but desired.

As some of the Fellows describe, A sweep and a scope
make alignment so much slicker. 

If you gotem useem.

If not, worry not.

Roger.
