Minimum discernible signal in 10 MHz , noise figure so we know how much
preamp is needed.

Greetings to everyone,
We have received a built-up transverter (3.4GHz) and local oscillator board
(3GHz) from the San Bernardino Microwave Society. Chris Shoaff N9RIN, a lead
designer for the board, also sent supporting documentary photographs. I'll
get those up on the site as soon as I can.
Question for the team: What measurements should be in the test and
characterization plan?
-Bandwidth characterized
-phase stability measured
What other measurements should we include, at a minimum?
More soon!
-Michelle W5NYV
