Hi = to=20 all.

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

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

Best=20 73.
