Not aware of any. Are you talking hard failure or failure to properly 
register SI sticks during an active transmission? Standalone box or one 
with serial or USB attachment?

The stick-to-box communication is 125 KHz and tightly coupled. Perhaps 
an SI box with an attached USB or serial dongle would have issues if 
improperly shielded, but a standalone box should essentially be immune 
to 80m or 2m transmissions at ARDF power levels.
