<DIV><FONT size=2><STRONG>Hello Mal,</STRONG></FONT></DIV>
<DIV><STRONG><FONT size=2></FONT></STRONG>&nbsp;</DIV>
<DIV><STRONG><FONT size=2>&nbsp;My poor experiment with a kite is not very 
conclusive in RX mode...</FONT></STRONG></DIV>
<DIV><STRONG><FONT size=2>&nbsp;The kite was 4.2 meter large ( delta design) in 
carbon fiber and spi snail.</FONT></STRONG></DIV>
<DIV><STRONG><FONT size=2>The wire was 2 mm aluminium. At 110 meter AGL it is 
impossible to tune</FONT></STRONG></DIV>
<DIV><STRONG>the variometer correcctly during a long period ( capacity move too 
much).</STRONG></DIV>
<DIV><STRONG>But it's works fine if you want receive broadcast transmitter ( 
like France-inter</STRONG></DIV>
<DIV><STRONG>on 162 KHz with 2.2 MW or BBC...!) I never receive OM LF station 
with this</STRONG></DIV>
<DIV><STRONG>antenna ( intermodulations).</STRONG></DIV>
<DIV><STRONG>Never forget to put a resistor between the wire and the ground and 
don't use</STRONG></DIV>
<DIV><STRONG>wire with PE or PTFE, the voltage will be very high&nbsp;by dry 
wind ( many KV!).</STRONG></DIV>
<DIV><STRONG></STRONG>&nbsp;</DIV>
<DIV><STRONG>My conclusion:funny but dangerous!</STRONG></DIV>
<DIV><STRONG></STRONG>&nbsp;</DIV>
<DIV><STRONG>I thing that helium baloon is the same but more expensive...the 
wire is heavy</STRONG></DIV>
<DIV><STRONG>and a little one is too resistive and delicate.</STRONG></DIV>

  <DIV><FONT face=Arial size=2>There is plenty of this around on 
  here!</FONT></DIV>
  <DIV><FONT face=Arial size=2>I am thinking of building or buying a small hot 
  air baloon. I thought if I could get a suitable design and materials I would 
  attempt to build one and use say a primus stove or small gas bottled device to 
  generate the hot air.</FONT></DIV>
  <DIV><FONT face=Arial size=2>Has anyone tried this approach or got any 
  ideas.</FONT></DIV>
  <DIV><FONT face=Arial size=2>Instead of unstable kites or helium balloons, gas 
  hard to get in large quantities. I thought a hot air tethered balloon might be 
  the approach. </FONT></DIV>
  <DIV><FONT face=Arial size=2>Your comments good or bad. I am not easily 
  upset.</FONT></DIV>
