Hello Andy,

How is this possible? Your Loop = points to=20 SE, my loop also points to SE. But we are not in one line. Actually it = would=20 be best for us if our loops would point to NE.
But i can receive = you at -16=20 dB SNR in WSPR with 1 mW ERP ??

Hi to=20 all.

 

This=20 evening, I=E2=80=99ll transmit to test a single turn loop on = MF.

 

  • 1 Watt HF=20 TX ;=20
  • Mode WSPR=20 2 and perhaps  also OP 8=20
  • Loop=20 description :=20
    • Vertical position, top at 11 meters, bottom at 1 = meters over=20 ground ;=20
    • Each=20 side wire is 7 meters long ;=20
    • One=20 single turn copper wire 10 mm diameter ;=20
    • Maximun=20 lobe NW / SE. Note : at 600 km, the front / side lobe is about 6 = dB=20 ;=20
    • Impedance 0.21 - 113 j ;=20
    • Current=20 wire 2.0 Amperes for 1 Watt output TX ;=20
    • Top=20 loading using a 3C90 tore isolated transformer ;=20
    • Base=20 tuning with a variable in parallel with a fixe capacitor. Total = needs=20 around 3000 pF of total capacitance ;=20
    • 50 Ohms=20 coaxial to the TX ;=20
    • Minimum=20 SWR at TX when the CV is well tuned : below 1.3 / 1.=20

 

Best=20 73.
