Hello to all.
 
To night I’ll test for receiving a 2 ground rods antenna on 136 USB, modes : OP 8, OP 32, WSPR 2 and WSPR 15, all at the same time.
 
Distance between the two rods : 35 meters. Each rod : 50 mm diameter aluminium tube, 2 meters long.
 
A low power test permits to tune the antenna to 50 Ohms. It needs an L network with a 275 µH serial coil and a 4.7 nF in parallel on the antenna side.
 
Bi directional receiving antenna azimuth : UK / VE one side and I / SV on the other side.
 
No preamplifier is necessary. RX is an IC7200.
 
Hope to copy you !
