Greetings,

I have a Plectron R519 on 33.78 that I'm going to have re-banded to UHF. The big thing is that I want it to alert to the repeater for 7,8,9,10. I've come across a table hosted on this site detailing the various tones used to alert Aetna, and I can't make heads or tails of it.



I would assume the 707.3-746.8, 707.3-879 set of frequencies would alert the Minitor 4's still in service on the repeater, and therefore work with the rebanded Plectron.

However, I could be just as mistaken, and the only solution I can come up with by myself is generating the tones, borrowing someone's Minitor 4 and a portable radio, and playing the tones over the dispatch channel until the right one worked.

Unfortunately, not only is it unfeasible, it would greatly annoy a fair amount of people.

So, the question is, what's the frequency the Plectron needs to be set to in order to alert after being re-banded to Aetna's repeater channel?

I'm not sure what you mean "Alert to the repeater". If you want the plectron to alert when Aetna gets a call, your Plectron should be changed to 453.300, and the fire tones would be 732.0-454.6 and the ambulance tones would be 732.0-307.8

707.3-746.8 appear to be Chief tones, which will only go off when the county needs to specifically alert the chief only.

Yeah, reading "alert to the repeater" back makes no sense :S "Alert off of the repeater channel" is what I meant to say.

Thanks for your help.
