Does anyone have any experience with the Ten-TEc 2-10 xverter? I am considering using one on my Omni VI+ to get on EME. I am just starting this, and know little about EME. I read that you need a low noise figure for EME, but the Ten Tec specs say 7db. That seems high to me. Does an antenna mounted pre-amp negate that high figure? Do I need to worry about it? Thoughts appreciated. 73, Bernie K5XS
