I was just thinking:
MAYbe he did mean "cheep". There is a list of birdies for the R-390A, and I
assume a different list for the R-390/URR. I might have it buried in the
archive here, but a quick search does not find it. Maybe it was in "The
Engineering Report...".
In Europe they call them tweets. Some folks call them "mixing
products". If I remember correctly, the Racal manual I have uses the word
"tweet". Quaint. Of course a higher order harmonic of a variable
oscillator mixing with a fixed frequency has greater tweet-ness. A little
while spent with an LM or BC-221 frequency meter will show this nicely. As
someone famous said: "Britain and America - two countries divided by a
common language."
Maybe I can start a cheep tweet thread. I think I need a vacation.
But there's nothing wrong with me ... wrong with me ... wrong with me ...
wrong with me ...
