Hello Andy, all

thanks for the info and for the activity.

I'm at your S-E direction so maybe i have some possibility to catch your signal. So i will listen in WSPR2 and OP8.

Hi to all.

 

This evening, I’ll transmit to test a single turn loop on MF.

 

  • 1 Watt HF TX ;
  • Mode WSPR 2 and perhaps  also OP 8
  • Loop description :
    • Vertical position, top at 11 meters, bottom at 1 meters over ground ;
    • Each side wire is 7 meters long ;
    • One single turn copper wire 10 mm diameter ;
    • Maximun lobe NW / SE. Note : at 600 km, the front / side lobe is about 6 dB ;
    • Impedance 0.21 - 113 j ;
    • Current wire 2.0 Amperes for 1 Watt output TX ;
    • Top loading using a 3C90 tore isolated transformer ;
    • Base tuning with a variable in parallel with a fixe capacitor. Total needs around 3000 pF of total capacitance ;
    • 50 Ohms coaxial to the TX ;
    • Minimum SWR at TX when the CV is well tuned : below 1.3 / 1.

 

Best 73.

 

Andy. F6CNI
