Radio eats GPS signals

[jetfour]

Hi folks,

This is 'out of left field' as regards aviation, but I know that some of us share a recreational love of sailing. Have any private fliers experienced any similar problems - airborne or otherwise?

Bought a new NASA Marine DSC VHF radio. Have a Magellan Meridian GPS. Both work fine - on their own. Switch on the radio, whether interfaced or not and the GPS loses all signals. Just being close (c. 1 - 1.5m) and on independant power supplies is enough for the beast to lose the plot.

Any tech person out there got any ideas as to a solution?

Thanks in advance.
