[FSG-public] Repeater updates

[Bryan Fields]

I was over today doing some more work at the site, everything is still online
and operating.

I swapped the LMR400 coax out for 1/2" heliax and grounded it for one of the
business band repeaters today, and remounted the GPS antenna on a better mount.
I pulled 9 runs of CAT-5 for the data radios and installed a UPS from home too.

Granted this doesn't seam like much, but there is quite a bit that goes into
putting in coax. 

  * The heliax needs connectors on it which takes about 20 min per connector
    to install.
  * Coax needs to be grounded with a ground kit after it's installed, and this
    requires antioxidant compound and cleaning.  Then you have to seal up the
    jacket of the coax.
  * once inside the shelter you need to install a lightning arrestor with more
    antioxidant
  * then a jumper of coax is made up and fished in the ladder racks to the
    repeater.

Tomorrow we will get the grounding done up at the top roof and some final
tweaking of the antennas completed.  If all goes well I'd like to get the 440
and 900 mhz repeaters interfaced to the computer controller and off the
internal controllers.  This will allow us to link them to the 220 and other
repeaters once the internet is hooked up.

We may be adding a pre-amp to the 440 repeater to see if we can get it hearing
a bit better.  The 220 is working well enough to not mess with at this point. 
900 seams to actually be working well as far as I can tell.  We've not heard
many people on 900 to test with.
