Brockville police enhanced their voice inversion, one step further, by adding the Variable inversion frequency by Random Code or simply Random code voice inversion. Everytime an officer keys up or dispatch, it sends out a squawk which contains the data for the sync ratio. The sync is the ticking u hear every few seconds through the transmission. The sync rate is how fast the ticking is occuring. Sync = syncronization. If its faster, the inversion frequency is higher, if its slower, then the inversion frequency is lower and it is always changing. The main point being that u would have to keep adjusting the inversion frequency according to the sync to be able to unscramble it each time without knowing the actual data that is contained in the sqwuak. A pain in the ass, but if you use a pot on your ramsey device to alter the frequency u could turn it up or down, by listening to the sync rate. Its the only way to do it, even then its not perfect, but u can make the voice out, even if its a little higher or lower in pitch.

Dont be confused when i say inversion frequency, that doesnt mean the radio frequency, in this case 142.935 mhz is the radio frequnecy, but the inversion frequency which is the audio portion of the transmission, is well roughly 3.2 khz, or so, and u will have a +/- factor of a few hundred hertz depending on the (inversion frequnecy) selected through the random code. Its a complexity to understand, but try playing with it for a while to see what u come up with. The inversion frequency can only be so low and so high, there are upper and lower limits to it when these devices for the radios are manufactured, because if it ever goes out of that spectrum, it cannot be reinverted, and voice pattern would be unrecoginzable even to the officer recieving the transmission.
What is also kind of funny, is you can have 2 syncs going at the same time, when one officer keys up while the other one is still talking, and dispatch says "10-9, both units were garbled". There is no system in place to prevent an officer from keying up and creating another sync pattern (ticking), now u have twice the ticking, and everything is messed up. So patients is required. Its quite an old method, but cheap, thats why the radio service provider mentions this option to the department using it, to save money, instead of buying a whole new digital system. Mainly used in smaller departments, ones that cannot afford the big city cost of implementing a new digital system.

Jammin Jay, good post, very informative. Thanks

Now what do you mean by using a pot ontop of my ramsey? And im assuming there is no other way of listening other then the method that you have mentioned.

To bad there wasnt some kind of software that could "check" the frequency and automatically deocde it.

Well, you would have to know about electronics, a pot is a potentiometer, it changes the voltage level of the circuit pathway. Actually, just private msg me, and i can help you out. Rather then explaining a whole paragraph on here.
