Joe,
 
can't really say I'm seeing much = here so far.=20 Not even in 438 =B5Hz, except for a couple of dim pixels in a row around = 21 UT.=20 Hartmut's grabber is doing much better at 11 mHz!

Hi=20 Markus,

Carrier on since 1920 UTC. 5 watts.  While looking = at the=20 messy breadboard
and trying to draw the schematic, I decided that it = would be=20 quicker to just
run the Decca using the power supply for the class E = amp at=20 reduced
voltage.
