Big Feet,
I have recently installed a 2.4G into my Telemaster, and the installation is clear when notifying the installer to ensure the Rx antenna are 90 degree from one another. Now I don't know if the sattelite will make this different, but you could try to arrange the antenna leads for the Rx as instructed... tis may clear up the interference. Also, one must use a resistor type plug on a fuelly, when using the 2.4G set up, to curb interference. Give it a go.

Keep you head up on a swivel.
