Am I losing it? (That's a rhetorical question - calm
down.)
I have been agonizing over the A4 Orion 9 MHz IF
schematic. In the upper left is, what I believe, some
signal conditioning for the SWEEP function. It looks
like connector J7 TMP takes the IF board output to the
SWEEP amp board A13.
Today I decided to look at the A13 board schematic.
Well it looks REMARKABLY like the upper-left of the IF
A4 board? (If anyone is interested the schematics A4
and A13 are available at: (
http://rfsquared.com/file_download/25 and the
schematics are 81910.pdf and 81957.pdf)
I guess I find it strange that all this signal
conditioning wasn't on a single board? Am I missing
something? Has anyone taken a look at these circuits
to evaluate what the T-T engineers had in mind?
Thoughts? Thanks!
73,
