Jeff Rowland remote control frequency?


Does anybody know if Jeff Rowland remotes share ir frequency with a more common brand (which would be listed on universal remote list)?

Just purchased a Concentra with remote MIA.

Thanks.

In case no one knows off hand I would contact JR. I purchased a Conrad Johnson transport with a missing remote and CJ informed me that it was based on a Phillips platform. I picked up a universal and set it for Phillips and it works great.
Hi,

it's the frequency of Toshiba TVs.
