Hello Phil and all,
I have 3m dish and I can share my experience with you.
My dish has 0.34 f/D and I use RA3AQ feed and 150W SSPA.
With that setup I was able to make 29 qsos on CW random during last ARRL
I would work more but I was sharing time with my 2m and 70cm activity.
I was able to hear much more stations with this antenna, but my small
power was not enough to catch them.
I agree with DL4MEA that illuminating dishes with low f/D is difficult
and I think it makes my signal weaker.
You can hear signals received with my station on my website -
http://sp7dcs.webpark.pl (click EME signals and choose 23cm band).
You can also hear how my signal was received by G4CCH with 5.4m dish on
Howard's website - http://www.g4cch.com/sounds/hearsome.html
It will give you some impression.
I am sure that 2.4m dish will give you also possibility to make many
qsos, but you will need to have good feed, preamp and more power - Sven
SM5LE is a great example of perfectly optimized station..
Of course this setup will give you a lot of fun and you will get 23cm

> My feeling is that it would be marginal on 23cms; and above 23cms the

> 23cms activity is very nice but i need a bigger dish i guess...
> Just a note on the ZS-FR tropo qso mentionned in the NL. It was the

> Longer paths have been worked on some other areas.
