I'm trying to find out what frequencies of IR carrier are used on the majority of HD sources available. So, I thought I would start out by asking the question here.

Does anyone know? Is there another place I can get this information from?

38Khz is a common standard, but I'd like to know if that's what is in use for any HD sources you have knowledge of.

Many thanks in advance,

Doug

P.S. this is research for me to inform a manufacturer of IR repeater products.
