Well, we got the rest of it done.  Finished putting up the 432 antennas 
and the station tested with them.  All OK including computer software, 
etc. according to Ron.

We also got the 432 4xRIW-19 array up and going, thanks to Kos, Scott 
and Ron mostly.  They've got the tracking software and interface going 
and tested.  It looks good.  Kos and Ron stayed until about 5Pm working 
on that stuff.

The 2m antennas are also up, but we had some interesting times with the 
new cables as we decided to test everything we could with the analyzer 
as we went along.  Two of the new cables had excessive loss and caused 
us to see too high an swr (about 2.5).  Ron thinks it was a bad batch of 
cable as he has taken the cables home and tested them again with his 
'259(?).  He is making more cables, but we had enough stuff here to get 
everything going anyway.

Interesting that we keep finding so many problems, even with new stuff 
and that some of the old stuff was so bad now that we have such 
sophisticated analysis instruments.

I am borrowing and will have at the contest this weekend, one of the new 
Comet analyzers and a Kuranishi analyzer which we will use for some 
further comparisons.  If anyone has an MFJ-269, please bring it as we'd 
like to use that too for the testing and comparisons.

On Sunday we had myself, Ron, Scott, Tom, Kos and Dusty finishing up all 
the stuff needed.  So the stations and antennas are all ready to go for 
the contest.  I will send a separate e-mail about times and food.

Bob
