When i program my radio there are two areas for tones( CTC/DCS Dec and CTC/DCS Enc) i know ones incoming signal and the other is outgoing signal but on RR there is only one "Tone" given. Witch area do i put the tone in.
Tones?

Most ham repeaters only require a CTCSS tone on the frequency you transmit on, so you want to put the tone in the CTC/DCS Enc in your radio.

Where two tones are listed the repeater uses one for its receiver and the other for its transmitter.
Where only one tone is listed the repeater usually, I say usually, uses the same tone for both receive
and transmit.
Common practice on amateur repeaters, but not by any means universal, is to have the access to the
repeater require a tone while the output of the repeater is carrier squelch.
AFAIK, all, or almost all, ham transmitters can only handle one tone, whereas commercial radios are commonly set up for the split tones setup.

I would suggest that most repeaters use the same tone on input and output. (I only know of one in the Phila/NYC region that uses different tones.) From my perspective near the line dividing of two coordinating councils, I like and use the PL on the output. I don't have to listen to the weaker NY machines burbling at the noise level. YMMV.

The tone that's listed in most repeater databases is the tone that the repeater needs to hear for it to start transmitting the signal. So that means that you'll need to put the tone in the "Encode" part of your radio. The "decode" tells your radio to open up its squelch only when it hears the selected tone. This is only optional, and some people use the decoding tone function on their radio with repeaters, but not all repeaters encode their signals. Quite honestly, repeaters are the only reason why you would ever want a tone on your signal. I've never found PL codes useful on simplex.
My Yaesu's can all do split tones.

Icom W32A's (HT) can do split CTCSS as well. No DCS, though.

What is a split tone for? One tone to transmit and one to receive? That sounds like fun to program...LOL

Yep, one encode tone and one decode tone. Ease of programming will depend on specific makes and models. It's not that difficult on my IC-W32A. I don't recall if/how my Kenwood TM-D700A does split tones. I haven't used it in quite awhile.

It's funny you mentioned this...today four of us on a repeater in New Jersey all tried to hit a Manhattan machine KQ2H needless to say no one could we were wondering if they have a special decode tone.
This might be a little off topic but was the repeater a "closed access" repeater? It's possible they could be using a sub-standard encode tone on the input?

Maybe now it is. Every list I checked has 82.5 for the input tone but I think they changed it.

I think your right I found the tone right HERE written in red they have one for TX I FINALLY hit the machine!!!
