Measure the receiver's sensitivity with a calibrated signal source. > Second we now have our IFR 1100S service monitor back.

Of course, anything can be tuned by doing your own "tracking" and listening carefully, perhaps graphing the numbers from something like a Sinaddr... (There's always some way to do it.) But a tracking generator would make the job much faster and accurate. A Vector Network Analyzer makes the job virtually fool-proof, but few of us have access to those. No clue what the Synchronizer is. Sorry. > I also picked up a Micor base of some sort at the surplus > store.
