Stupid error in transmitter circuit

[<col...@hi...>]

Hi *.*,

yesterday somebody drew my attention to a really stupid mistake in the  
transmitter circuit on the LIRC pages.

The description recommended the SFH485 IR LED, which in fact is  
transmitting at 880 nm while we need 950 nm for CIR applications. It will  
still work with this LED but the range will be only a fraction of the  
range you can get with a suitable LED.

So if you are using a SFH485 and have problems with range or reliability  
of your transmitter, please consider replacing the LED by a LD 271, LD 274  
or SFH 415-U or whichever LED you can get that is operating at 950 nm.
