474.2 kHz

27 and 28 March    Aurora  no WD2XSH/17  decodes


last night with repaired antenna  25 March
50+ decodes again
strongest -9  no other TA signal here
2017-03-26 01:14  WD2XSH/17  0.475640  -9  0  FN42pb  5  PA0O  JO33hg  5630  49 


Desktop QTX s QRP  but  been decoded  by WD2XSH/17 and N1BUG

WD2XSH/17 last night  14  decodes rather weak  -23dB  at best

Today in beautiful weather I showed my antenna's to Marten PA3EKM he brought me the right type s left - right manipulator switch for the 630m tuner.
Then saw the W- Beverage was broken most of the wire laying on the ground and in the ditch but it still receives.

 but first time spotted in EA8


Now with the IRFP4227   in the QTX instead of the IRF540Z types
 I had no more blown FET's even not with a short in the coax
It is fail save now.

And  easier remote tuning the Variometer with  a motor left right switch .
Needed a double pole switch with  neutral mid position.
But those switches appear to be hard to find
A single pole manipulator switch with 4 relais Arduino unit can do it
The motor in the tuning unit at the base of the L antenna  is  0.5 rpm at 12V
At 5V  over a 100OHm resistor  even slower 0.1 rpm
The meter is antenna current indication for max tune direct conected with
the Hagenuk Variometer Strom Wandler.
The whole control could be nicely done with Arduino
Including  V A   Ant. current and  Power display.
That's is a new project
