[Moon] Fw: [Moon-Net] Z21EME on 2m and 70cm with 1Y

With limited funds, I am having to chose which 
bands to activate.  I have worked a small handful 
of stations on 70cm using my dish with 
rudimentary feed and 100w, but am not encouraged 
to invest for 1000w and full-blown feed for that 
band.  70cm-eme is in limbo as far as my 
future.  I have a 125w amp but mixed feelings 
whether to build a good feed for 70cm or just 
skip it. 125w would only be good for JT65.

Instead I will be on 23cm-eme with both CW & 
JT65C.  G4CCH was my first CW-eme contact running 
only 50w.  Now madly working to have 100w+ ready for this weekend.

Then I will work on my 6m-eme system and 
finishing the 1296 300w amp.  Winter project will 
be working on 3400 for a goal of spring QRV.

So there you have it.  70cm doesn't attract me.
