Sigh. Not hearing anything from the Moon.
Tuning into the live ustream.tv video/chat line it appears that lots of people with much larger/better setups than me are also having difficulty hearing anything, so I am not the only one. Given that under the best of circumstances, my unproven antenna would have barely enough gain, I think this attempt has been somewhat unsurprisingly unsuccessful.
Sarah was nice enough to at least snap a picture of my standing out in front with my antenna, looking goofy.
Addendum: It appears that they didn't have their power amplifier up today, so were operating at a lower power level than was originally hoped. With luck, they'll have that fixed and will be +13db tomorrow by comparison. I suspect that still might not be enough. But I'll try again tomorrow, just in case.
