G'day, all.
This popped up on Moon-net today; I thought I'd bring the associated URLs across, for those who aren't subscribed to it and may enjoy the view.
ES5TV has a new coat-hanger in his backyard. An array of eight 5-element Yagi, for the purpose of EME on 15 metres. No, there are no typos in that sentence... The tower is 70 metres tall - so maybe a smidge taller than the one Ian VK3MO has, just to the south of Kyneton, for those who may be familiar with it.
The photos of the 2-day installation are here: http://pontu.eenet.ee/es5tv/ There are a lot of them...
And there is a video of the installation, plus the first contact made using it, here: http://youtu.be/Z9fDlbIFhMs
Gad zooks!

15 m EME.
Re: 15 m EME.
What..... No evelation control? 
Impessive setup, and I wonder if stations with a relatively simple setup will be able to hear or make make contact with him when the moon is low?

See him echo testing.

I would say he is the only one capable of EME on 21MHz.
So looks like he will be talking to himself for quite a while. Wonder what the ionosphere does to his signal on the way to the moon (at certain moon elevations)?
It will be a killer signal on 21MHz terrestrial.
I wonder if the NSW tower regulations be accomodating with this baby.

Re: 15 m EME.
VERY, VERY impressive array 
I especially like his ideas on being able to vary the main lobe elevation, and his observations on DX signals there. Certainly that would give him a MUCH bigger window of opportunity for EME.
If you Google HF EME or 10m EME, you'll find a bit of info from people that have tried it. It's been something I'd love to have a shot at. A decent 10 or 15m yagi and reasonable power should do it if you have reasonable ground gain. Don't forget that path loss is considerably smaller at HF. It's not easy, but especially with JT65, there are a lot of 10 and 15m stations that are capable of EME contacts without knowing it.
Some history:

Some experiments on 17m with only 200w:

And a write up from JH1KRC on 15m with just 6elements:

Plenty more if you hunt for it....
Edit: Just remembered the HAARP Program in Alaska did some around 40m in 2007/08: http://www.haarp.alaska.edu/haarp/mbAnn.html
