Hi Joel,Thanks for the tip and perspective. I've reached out to Peter first.
Two questions to ask, if you don't mind...
When you refer to a single-yagi station, what size (or gain) antenna do you
think was in use on 2m and 70cm?
Do you think that elevation control at play for them or were they home stations
aiming at the horizon?
I'm thinking what it would take to setup at a hamfest or a field day to
demonstrate EME, and make it a plausable approach for observers who are not
likely to go home and setup H-frames. :-)
I'll take further questions direct after this to avoid flooding the list with
non-contest stuff.
I sure appreciate your insights.

Hello Ev,
I operate EME on all of those bands (current and "back in the day) plus 222
MHz. Of course, the best person to get feedback from for the type of operating
you're inquiring about would be Peter, KA6U. Also Gene KB7Q.
144 MHz will have the most activity, followed by 432 then 50 MHz. With a small
portable station you will have to use the digi modes. The 2-meter folks still
hang on to JT65B, the 50 and 432 gang use Q65.
When Farraday rotation is not in play I can work a single yagi station with 100
watts on 144 and 432. 6-meters is more difficult as you will need some power
with a single yagi.
Chat with Peter or Gene, they can tell you more than you probably want to know
about portable EME operating !!!!!

Subject: [VHFcontesting] 6m, 2m, 70cm EME
Of the 6, 2, and 70cm bands (those that are most likely to be in a modern HF+
radio), which band has been shown to support EME with the least overall ERP?
I'm thinking "portable EME" where it isn't possible to transport big antennas
or a generator to have a kw amp. :-)
Assume that this portable station would target QSOing with only the "top tier"
of well equipped DX stations.
I'd be interested in only recent experience rather than "back in the day". Also
interested in both CW (human decode) and FTx (machine decode) modes.
How little power and antenna (ERP) has been successful in making EME contact(s)
and on what band/mode?
