Hello Lowfers !
This is a more practical report for a change after all the math regarding ERP 
etc. etc. .
I finished my rx - loop with a side length of 1.75 meters at a square design and 
12 turns ar a length of 1.2 meters.Basically i used an old homemade centerpiece 
of a spider Quad and inserted broomsticks into it-A real EL Cheapo and EL 
Speedo design.Drilled holes into the Horizontal bars to hold the wires in 
place.I resonated it with about 3nF and fine tuning with an 
air-variable.Matching with an unbal/unbal at the cold end of the loop,i could 
have run it symmetrical but chose to put ground potential to one side.
>>From there i run coax into the crystal filter.
otential to one side.
I found the resonance pretty sharp and the minima on the sides are about 30db 
down.I will try to evaluate the horizontal width for minus 3db for fronts and 
sides.At the moment i have to turn manually,that means if i get calls from the 
"wrong side" i may be in a bad position.
So far no qso with the new one but hope tmw morning the traditional activity 
comes up.But in the long run it will be mandatory to rotate it remotely.
At the small given number of stations active we cant miss out on a single one.
Rite now i can hear some T&L approach-which is normal here after a few hot days 
in a row.

73 to all the friends "down there"
