Arduino Yun and IRremote - D13 for output IR signals as default

Development Tools IDE 1.x

Hi! I'm sorry for my english =)
I try to control my TV with Arduino Yun. I use IRremote library.

One of examples:

/*
 * IRremote: IRsendDemo - demonstrates sending IR codes with IRsend
 * An IR LED must be connected to Arduino PWM pin 3.
 * Version 0.1 July, 2009
 * Copyright 2009 Ken Shirriff
 * http://arcfn.com
 */

#include <IRremote.h>
IRsend irsend;

void setup(){
  Serial.begin(9600);
}

void loop() {
  if (Serial.read() != -1) {
    for (int i = 0; i < 3; i++) {
      irsend.sendSony(0xa90, 12); // Sony TV power code
      delay(40);
    }
  }
}

All examples said to use D3 for output, but it's not work.
I was looking for a solution. So, I found that D13 works. Is it OK?
But signals are too low - I can control my TV at distance not more 2 meters (7 feet).
I think the problem is that D13 has its own resistor. Am I right?
The question is - how I can change the pin for output IR signals?

P.S. I've read this topic: Changing Pin settings of an IR Library - Troubleshooting - Arduino Forum but I afraid of doing it.

Th Yún has an Arduino Leonardo on-board.

For IRremote on the Leonardo pin 13 is used by default, which should also apply to the Yún. I understand the existing LED on 13 will not be a problem.

To get longer range you will need to add a transistor driver circuit for the IR LED as the Arduino can only supply limited current.
A quick search on this forum or google will provide many example circuits. You will require 1xNPN transistor and 2 resistors, in addition to you IR LED.

If you want even further range then you could try this out:

Thanks a lot
