I finally got enough documentation to get the 5760 TWTs working.  Using =
a Down East transverter, I get 20 watts output.  The amplifiers are =
complete with power supply.  They require -48 VDC at about 4 A.  These =
are really rugged NEC units.  I will bring a couple of them to Midwinter =
Madness if anyone is interested.

I also have some of the WE-61 elliptical waveguide with WR-137 fittings  =
for each end.  WE-61 is rated for 5.6-6.2 GHz with a loss of 1.25 dB per =
hundred feet.  If anyone is interested, please let me know by Thursday =
so that I can cut and coil for transportation.  $100 for a hundred feet =
and two connectors.  The waveguide will roll up to 4 feet diameter coil.
