Trudy's Radio Repair

 is a quest in Fallout: New Vegas.

Quick walkthrough
In order to fix Trudy's radio. located behind the counter of the Prospector Saloon, simply go up to it as if you were going to turn it on, and it will bring up a menu to either leave it alone, or repair it. If you have a repair skill of at least 20, you can fix it. Return to Trudy after, for some caps.

Detailed walkthrough
To fix the radio you need a repair skill of at least 20, once you have that you can begin. All you have to do is walk behind the counter and look for a radio, once you have found it, it will come up with: "Repair with 20 repair skill" or "Leave it alone" if you don't have the repair skill then you will have to leave it alone, but if you have the repair skill then repair it and then report back to judy. She rewards you with caps (50 if I can remeber correctly) and you can barter her 25 more caps out of her with the barter skill of 20.

If you are having trouble meeting these skill levels, then go outside and look in all the mailboxes you can find. These are usally filled with junk but a few have magazines to increase you skill levels temporarily. But the magazines only increase the skill levels by +10 so you will have to have at least have the skill levels at 10 or find one book and buy another at the goodsprings general store if they have them in stock.
