Also, I was going to mention if you have a smart phone you can get the repeaterbook app and it will give you the closest (approximately) repeaters to you. I've been using it for a while because I was kind of in the same boat about not knowing where repeaters were or what tones I needed etc. It works really well.
The RepeaterBook App for Android (linked below) lists many local repeaters and their offsets, and their type, and their access tones by distance from your location. Very helpful App.

I just edited the comment. If you're not comfortable blasting your city name to the world, I understand. Feel free to DM me.
Do you have the Repeater Book app? I used to add new repeaters and update old ones via this app, years ago.

There's also the ARRL Repeater Book but I've read some bad reviews. YMMV.
If you're in the middle of nowhere, are you familiar with the Wilderness Protocol? The Primary Freq is the National Simplex Calling Frequency, 146.52 MHz FM.
I used the Google app repeater book to find

Depends on your country, obviously.
In Germany, the DARC is quite nice: for example, here is the list of relays near me.
I also like the Android Application RepeaterBook
IDK if repeaterbook works over there, but I use the repeaterbook import in chirp to program my HT, and I have the app in my phone which lists all the repeaters inside of X(i usually leave it at 25 miles) around my current location https://play.google.com/store/apps/details?id=com.zbm2.repeaterbook&hl=en Edit: looks like it might not cover over there but here's this http://www.ukrepeater.net/repeaterlist3.htm
It's on Android too.
Installa o repeaterbook ou vai ao site repeaterbook.com e encontra um repetedidor perto de ti, ve se consegues ouvir.
Can I just use this app?
Get on the air and find out! Also, go get your general regardless. It will be a game changer and once you get it, it's yours (essentially) forever. You won't regret it. :)
There is an android app called RepeaterBook which will show you a list of repeaters near your location.
