My antenna is a 1/4 inv L full size for 472 KHz height over 33metres.

I do not need a variometer

Hey Mal,

I got WSPR report's from many DXCC's (e.g. Finland, Italy and Spain, ODX abt 1900 km). The station has only 50W and modest antenna, inv. T. abt. 10 meters up and 2 × 20m horizontal wires.

It's even possible to get receptions in a range of 800km with. 1,5 W and the same antenna.

In the beginning I had the same problem. 10db in hand but only one reception...  The solution in may case was to build a betther variometer and betther hf-ground.

I am able to decode WSPR sigs at –30 dB level yet no one beyond M0LMH can receive/decode my signal. M0LMH receives me at around –18 dB therefore I have at least 10 dB in hand but no one has the RX capability to detect my signal. It seems I need 1 Kw it seems to be heard
