Hi Bob.  Not dumb at all.  I'll answer as I go.

I'm at approx 800 ft elevation. Medium to low level.  The nearest wide 
digi is atop a Mt 2407 ft on Mt cheaha, Al.  It is 30 miles away.

Relay digi is 16 miles away in another direction, which makes a kind of 
triangle with mine being the northernmost point.

My KAM is acting as a relay digi.  AG4AC-9

>3) Why is your home station needed as a digi?

Without it, in this hilly/mountainous region, often times local mobile 
stations don't seem to get very far, my mobile included.

A good choice.  Unfortunately, I am fully disabled and very tight on 
funds at the time.  Being on a fixed income raising three teenagers is 
indeed a challenge.  However, will change as is possible when funds 
permit.  The other two stations I mentioned are WB4GNA (Wide digi at 
2407 ft) and K4SCC (relay digi about 600 ft elev).  an evaluation and 
suggestions/comments welcomed by myself.

Understood.  If you check Central alabama, you'll see how we are 
situated here.  Lots of mountains and just a few digis at all right 
now.  Lots of nooks and crannies to hide a signal in.  Part of the 
problem is effective coverage of digis in the area.

I appreciate your taking the time to explain more of the issue.  PLease 
feel free to comment back at your leisure.
