Looking at nearby G0VQH's list of WSPR stations successfully decoded on 472kHz WSPR it is clear Jenny is copying far more stations than me. Even with my preamp in circuit and maximum sensitivity I am simply not copying, at all, some stations. I think it is time I tried an E-field probe on this band on RX. It is a combination of antenna (in)efficiency and directivity I think that is stopping me copying more on MF now. I'm not sure what Jenny is using on MF but it clearly works well.
