[NLRS] New 10 GHz Player

[W0ZQ at aol.com]

Hi Scott, congrads on getting your 10 gig amp operational.  Yes, most  of us 
are running 141 hardline for the various interconnections.  I am less  
familiar with LMR-240, especially at 10gigs, and suggest that you also use 141  for 
that run as well.  How much loss does LMR-240 have at 10gigs compared  to the 
same run of 141 and is LMR-240 usable at 10 gigs ?  If you mount the  
transverter on the tripod leg, that may make portability a problem .... my 10gig  
system splits in to two pieces with the tripod separate from the  dish/transverter, 
making it easier to place in the car, etc.  I can go from  car to set-up (and 
back again) in about 15 seconds.  Also, don't forget  that you need to design 
it so that you have the ability to elevate the  dish.  There are times when 
aiming "up" helps, so your system should be  designed so you can elevate it.

Since the weather is miserable  today (snowing AGAIN!), I devoted the 
afternoon to finishing up the 10 GHz  PA module.  It is done and tested.  
Was able to get 4W out with  the full 10 mW drive from the transverter.  
I set the transverter drive  level to obtain 2W out of the PA module.  
I'm going to run at that  level and see how it works out before jumping 
up to the 3W level DEMI says  it can do.  I'm a conservative after all ;)

So, the guts of the  system are now complete and I can turn my attention 
to assembling the system  components together and get some good RF cables 
to tie it all  together.  I'm thinking of using a short run of UT-141 
between the amp  and the feedhorn (the amp will be permanently mounted to 
the bottom side of  the feedhorn arm).  Then I was thinking of a run of 
LMR-240 from the  transverter to the amp...probably around 2 or 3 feet.  
I hope to be  able to mount the transverter on the back side of the dish 
or maybe to a leg  of the tripod.  Comments?
