Another interesting technique I learned about a couple of years ago for setting FM deviation, if you don't have something to measure it handy, is the Bessel-Null method.
This would seem to relate well to the "poor-man's service monitor" topic. Randy KC6HUR published some information on this for those setting levels on IRLP systems and credits VK1OD with the original information: http://irlp.kc6hur.net/FmBcastSetup.php Nate WY0X
