Neat to look at Nate, My first poor mans service/deviation monitor was a display tacked onto the a$$-end of a radio shack scanner. Once I saw and recorded the relative deviation values from a known service monitor (on the most popular bands)... I could fudge a deviation pretty darn close.
I then "upgraded" to one of the Heathkit Deviation Meters... After a time I again used the scanner deviation display as the easy to use quick check. Don't laugh... it did work pretty well for what it is/was. cheers, skipp > "Nate Duehr" <[EMAIL PROTECTED]> wrote: > 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 >
