[amsat-bb] Frustration

I've been trying to get my receive setup going the last few days but I'm 
having horrible results. I have my 11 element 70cm "cheap yagi" back up 
on the mast and my homebrew SaebrTrack and OR-360  AZ/EL TV rotator 
system interfaced to SatPC32.
  I have an ARR preamp mounted at the mast fed with a seperate 12VDC 
feed and about a 40 foot run of  JEFA  brand LMR 400. Once I get into 
the shack there is a bit of patchwork to the cables. I'm using a Yaesu 
VX3 to receive and due to the SMA connector on the HT and not wanting to 
strain it I have a 4 foot adapter cable  of  LMR 100 that goes from an 
SMA to a SO-239. I then have to use a short length of coax with a PL-259 
to N male to mate up with a N barrel connector connected to my LMR 400 
coming from outside. Now obviously, I know this isn't optimum and eats 
up valuable RF and I intend to change it ASAP  but I'm hearing 
absolutely nothing on AO-51 passes. Not even the hint of signals.
I'm thinking with that preamp in the line I should at lest hear 
something discernible besides noise regardless of the patchwork of 
cables. Am I off base in thinking this? I did catch just a bit of 
discernible signal off  SO-50 last night but it was almost overhead.
 I'm not a beginner at this but I'm frustrated. Perhaps I'm putting too 
much faith in the preamp to push the signals through my hodgepodge of 
adapters and cables? Any thoughts are appreciated.
