In or Out
That's the output. Hams almost always refer to their repeaters by the output.
The radios have a setting for + offset, - offset or simplex, and the newer ones even "know" the bandplan for when to do which. So you just dial in the freq, and the radio "knows" the rest. All you have to set (sometimes) is the PL tone.
If you'll look at the w5ias.com website, you'll see all the TARC repeaters. The UHF link system remains linked 24/7, so if you travel around the eastern 1/2 of the state, you can always hear what's going on everywhere, as long as you can jump to the nearest repeater on the linked system.
For nets, we link the 2m (145.11) to the UHF side, and get contacts from 5 states (KS, AR, MO and TX are the others).
If you're interested in getting your license, the TARC holds licensing classes a couple of times a year, or you can get the book and study on your own. If you get stuck, come to a club meeting and we'll hook you up with a mentor.
Test session schedules are linked on the site as well.
