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 ...
