I used the following program to send an IR code and I got the an unexpected result as below:
/*
IRremote: IRsendDemo - demonstrates sending IR codes with IRsend
An IR LED must be connected to Arduino PWM pin 3.
Version 0.1 July, 2009

*/
#include <IRremote.h>
IRsend irsend;
int j = 0;
void setup()
{
}
void loop() {
for (int i = 0; i < 3; i++) {
irsend.sendNEC(0xFF6897, 32);
delay(40);
j = j + 1;
}
delay(5000); //5 second delay between each signal burst
}
I expected to receive:
FF6897 Decoded NEC: FF6897 (32 bits) Raw (68): 8750 -4450 550 -550 500 -600 550 -550 550 -550 550 -550 550 -600 500 -600 500 -600 500 -1650 550 -1650 550 -1650 500 -1650 550 -1650 550 -1650 500 -1700 500 -1650 550 -550 500 -1700 550 -1600 550 -600 500 -1650 550 -600 500 -600 500 -600 500 -1650 550 -550 550 -600 500 -1650 500 -600 500 -1700 500 -1650 550 -1650 550
Instead I receive consistently
C101E57B Unknown encoding: C101E57B (32 bits) Raw (68): 8850 -4450 500 -650 450 -600 500 -600 550 -550 500 -650 450 -650 500 -600 450 -650 450 -1800 450 -1700 500 -1750 500 -1700 500 -1750 500 -1700 500 -1750 450 -1750 500 -600 500 -1750 450 -1750 500 -600 450 -1750 500 -650 450 -600 550 -600 500 -1700 500 -600 500 -600 500 -1750 500 -600 500 -1700 500 -1700 550 -1700 450
anyone knows how to fix this?

Schematic wise:
one IR reciever with VCC and Ground connect and signal-out on pin 6
