    Just out of curiousity.....what's the lowest band a
    successful EME QSO has ever been made on? 2m, 6m?

    Have any engineers/EME gurus ever just for grins & mental excercise tried to figure
    out on paper what it would take to do it on say, 10m or 20m?

    40 meters. Well, actually just outside the 40m ham band, and it wasn't really a 2 way QSO. HAARP did an EME experiment and the echo was heard by many listeners, including me, with simple wire antennas.

    Lowest frequencies hams use is 50 MHz (6m), and it's quite common.

    The government research HAARP system (High Frequency Active Auroral Research Program) runs 3.6 million Watts in the 2.8 - 10 MHz region and can get lunar reflections.

    That's a bit more power than I can run from home.:p

    I've done that a few times with nothing more than an Alinco DJ-G7, a whip antenna and some headphones. It's really not that hard and it's lots of fun.

    The most common band for EME is 2meters. There are operators on 6meters and on the higher bands all the way to SHF.

    10meter EME has been done. Check this link:

    SSB QSOs are possible but they are pretty hard. They are easier on the microwave bands with a big dish antenna and some Transmit power.
    There are some youtube videos you can probably find if you hunt a bit.

    But most starting stations will have small antenna systems and will limit them to working the superstations on WSJT using JT65B mode

    As Steve mentioned the huge dish at Arecibo P.R. was activated a little over a week ago on 70cm. They worked some CW and some SSB stations. It was a dry run for the Echoes of Apollo special event scheduled for 16,17,18th April.
