I've made several attempts efforts to work AO-7 on 
Mode A, but I just don't seem to be able to manage it.  
I can hear CW signal, and if I whistle into the mike, but I 
just can't hear my voice well enough to even attempt a 

I'm using an 80 watt Mirage brick into an RHCP moxon 
pair pointed straight up.  I don't have any problems getting 
into the FM sats with this setup.  Is it because I'm only getting 
about 40 watts EIRP from this and that's simply not enough
for AO-7 Mode A?
