[SJDXA] Work Party Re-schedule 11/07

[Dan Dembrowski]

  Report on things other than in the marsh:

   Vertical Dipole: Feedline and coil traps connected.  Untested

   Beverages: Feedlines run and boxes connected to all but the West. 
  Left West unconnected until configuation determined, 1 element or 2.

  Some deadfall was removed from a few of the antennae, Thanks Lance.

  We will have to revisit most and provide some new ground counterpoise's and a few new sta-kons to the wires as mother nature has done her dirty deed.

  All computers are functional. One has a noisy fan, will replace next trip.

  The Sloper switch box is a little banged up, I have it here to rework it.

  Everything else looke to be in order.

  Thanks for climbing today HM. 

  And of course thanks to the marsh rats for their fine effort. K2TW, W2CG, and of course, The Good GD.

  (think I'll get one for that, or will I have to wait in the pileups too? )

             DaNO....W2NO

  Report from the Marsh.

  First, the high tide was at least 2.5 hours after the Manahawkin Bay high tide!

  Loop:
  The loop (white wire) was cut to be per K2TW's optimized dimensions.  We raised it to have the apex down about 30 feet from the pulley.  The bottom corners are now about 8-10 feet above the ground.  Distance from the tower is about 10 feet.  All this is per what was in the model.

  NE Sloper:
  Marty set the screw-in anchor provided by N2OO about 15 feet beyond the old anchor.  We re-built the NE sloper -- the wires were cut for 135 feet.  About two feet was folded back on the top leg.  We installed the NE sloper pretty much according to the model data.  The top is loer than the loop apex and is about 20 feet from the plane of the loop.  The bottom leg does NOT cross the loop any more.  The lower half of the sloper is secured to an unused ground rod.  We'll probably need a stake to raise that up a couple of feet in case of snow.  A quick check of resonance showed around 1.725 MHz.  We'll need to significantly trim once  we put in the lower stake.

  W Sloper:
  We re-built the W sloper -- the wires were also cut for 135 feet.  About 2 feet was folded back on the top leg.  We tried to set the top of the W sloper at the same height as the NE sloper  and about 10 feet from the tower.  We used the exisiting anchor rope into the woods for the center insulator.  The geometry of this antenna is not per the model.  We really need to pull the anchor rope to the center insulator but first we need to find the end in the woods!  The lower leg does not cross the loop, but goes past the tower.  A quick check of resonance showed approximately 1.710 MHz.  Way to long right now, but it makes no sense to do anything until we fix the geometry.  ONE SUGGESTION:  lower the W sloper and connect the anchor rope to the center insulator as far pout as we can and then raise the antenna.  This should buy us some distance.  We may need to raise the upper end a few feet to help raise the lower end.

  Vertical Dipole:

  I don't know status of connections.  Can someone confirm?

  Receive antennas:

  I believe all beverages were walked, boxes connected and feeedlines run back to the shack. (Can someone confirm?)

  We did not find the short receiving vertical in the shed.  Marty is going to check his shed to see if it's there.
