[WARC] need person with 70. cm. rcv for test

[d-huber]

Maybe send out an email as to expected times and frequencies.. I have a ver=
tical on 440 and atv receiver here in Onalaska,, en43 ofcourse.... I could =
be of some help.

73,

 Dave, WV9E

  I have all the parts finally for the ATV repeater.  Want to
  test each part to be sure the total IS equal to the sum of
  the parts otherwise it is difficult to assess whether you
  are really getting out of it what you would "expect" as few
  other such machines in the area to compare with. =

  Actually....none.
  What I need is a person or two (more OK) who can be
  available now and then to compare signal strengths as I swap
  among three antennas, three feed lines, at three different
  heights.  NO, NOT ALL 27 COMBINATIONS !!!!  The tests for
  this part will just use FM voice on one of the ATV
  frequencies.  443.750 MHz would probably be good.  NO ATV
  equipment is needed.  What would be IDEAL would be
  someone(s) with a simple VERTICAL 70. cm. antenna.  Beams
  might be a nuisance because of the need to always set them
  back to the same bearing.  The idea is that I transmit a
  fixed power carrier and the receiving station notes the
  signal strength (any type of "S-meter" reading is fine,
  doesn't need to be calibrated).  When I switch to another
  antenna, feedline, height, etc. we coordinate (on another or
  the same frequency) and see how much I need to attenuate the
  signal on my end to get the same reading on your "S-meter." =

  I can always measure gain/loss for the transmitter power and
  the feedline by other means but am very curious how much the
  height affects this and whether the antennas really meet
  their spec.s.  Picked up a DB-420 antenna at Dayton (16
  "folded dipole" array) but is used and want to actually
  assess it.  Will compare with two other fiberglass "sticks".
   Would like to check out tonight a few things to see just
  what power level will be needed to accomplish these goals. =

  FM voice is plenty adequate for these first
  measurements...plus I don't feel like carrying a video and
  audio source, transmitter, amp., bird meter, lead gel-cell,
  and batch of attenuators to the top of the tower too many
  times if I can calculate whether it is performing up to
  snuff from these tests.   jon wa0unb
