roger beep tone mod

[audio boy]

hi i was wondering if there is a dial in my radio that i can control my roger beep with, it's a galaxy 73v and is there dual controls or what?

hello audio boy,

i know theres a switch on the 73v, with the swr circut switch i think, but as far as variable volume control on the rodger beep i am not sure. on my galaxy,the 959, one of the dials you push in and that turns it on and off i think its the mic gain, ill have to look. But who knows, mabe there is somthing internal...

yea thats what im talking about, is there an internal dial because i see on cbtricks.com there is a roger beep tone mod

I did a little reserch on the galaxy roger beeps...


The rodger beep is controlled by R181. Its somwhere around 200K-220K Ohms. If you looking for a change in pitch on the beep, a higher resistance will give you a lower tone and a lower resistance will give you a higher tone...

The roger beep time is controlled by C134 witch is 2.2uF@16 volts DC. A higher uF will give you a longer beep while a lower uF will give you a shorter beep...

As far as an actual dial is concerned, i dont think there is a dial. But i am under the understanding that all of the rodger beeps installed by galaxy are pretty universal, and if im not mistaken, the boards between radios are also pretty universal too.

Hope I helped,

ok thanks

there is no user adjustment on a galaxy roger beep. the only way to have that done is to have a radio tech install a variable pot i guess is what they are called. maybe it could be wired to an external potentiometer. but as far as changing it "on the fly", that is not going to happen.

ok
