    Hello,<br>
    <br>
    I'd like to propose we allow spending of up to $2k to cover the
    costs of installing a photovoltaic (solar) power system @ Haystack. 
    The site owner has allowed us to host a site up there as long as it
    doesn't impact their power budget.  The site is not wired to any
    utility power, and transporting propane to it is expensive.  This is
    a 1-time cost, and the hardware will remain property of the site
    owner.  In exchange they'll be giving us new mounting points for 2
    dishes and 2 sectors, which will have a huge impact on coverage and
    extending the network.  Our recurring cost for the site will be
    $0/mo, which is an ideal long-term arrangement.<br>
    <br>
    Here is a list of the hardware required:<br>

      <br>
      In the $2k request, I'm also allowing ~$250 for shipping costs. 
      Solar panels are large.  Anything not spent will be returned to
      the HamWAN budget.<br>
      <br>
      We already have all the other hardware required to deploy the site
      in-stock.  Some of it is already deployed (Haystack-S3), and some
      is sitting on-site (modems, 1 dish, other sector).<br>
      <br>
      Our present balance is $1,291.04, so we'd be going into debt for
      this deal.<br>
      <br>
      The other cost of this deal is recognizing the site owner's
      sponsorship of HamWAN by including their logo in presentations,
      and offering some man-hours for site maintenance.  The big project
      this summer (aside from this solar system install and the full
      HamWAN site install) will be helping with installing a grounding
      system there.<br>
      <br>
      My vote on this deal is: YAY.<span class="HOEnZb"><font color="#888888"><br>
