Wow - what a great and slightly overwhelming response to my tower question !

I wish I had replied all, to the dozen replies I received in a few short 
hours ! (so they would be archived online)

>>thank-you thank-you to all!

To paraphrase the replies I've received, it seems like I am on the right 
track but not quite there.
I can probably expect a better match once I move the gamma connection up as 
high as I can get it and out from the tower 2'-4'  I may have to end up 
going to an Ohmega match (maybe) if I can't match it.

Certainly more than 12 random length (80-130' each) ground radials will be 
better than not.

I should reduce my tower clutter.  I have the twin sloper off my tower and 
also another dipole type antenna there too.  (a CW160).  Only problem with 
removing the A-D sloper is I will no longer have a reference antenna !

Two kind fellows guessed my tower was resonant on 2.2MHz, and by golly, I 
just measured it, and sure enough - it is !  I don't know why I didn't see 
this before.(daft?)  I have a local AM signal on 1.26MHz here and it's much 
louder on the tower than the sloper so I thought (mistakenly) that the tower 
was somehow with all my tower clutter (ie: wires), it was resonant way down 
there. DOH !

On 1.83MHz, the very low, short loaded sloper is at the very least 6-12dB 
stronger than the tower., . . .which STILL blows my mind. . . I thought on 
RX the tower would kick it's proverbial butt, but not if it's not resonant I 
guess.

Next weekend I hope to move the match up much higher and try to see where I 
am at.

A sincere thanks fellows.

Cheers,

Mike VE9AA
