US ELT installation issues for 2006 contests - clarification??

Hi folks,

Reading through some previous emails on this leaves
me a little confused;

Here's what I *think* I understand;

1 Experimental gliders; ELT does not need to be TSO'd,
owner install OK but need A&P signoff (minor modification,
not maintenance)

2 Certified gliders; ELT must be TSO'd, A&P installed
& signed off. (minor modification)

So if my glider is experimental I can install a Filser
ELT myself and get it signed off, but if it is Certified
I Need a TSO'd unit (like Ameriking).

I also read that SSA does not require TSO'd ELT as
per 2005 rules but I didnt find any 2006 rules anywhere
to confirm the change.

Can the SRA/SSA confirm that a non-TSO's ELT is ok
for contests?

Thanks
