Roger,
are you using the
same dial frquency of 0.503910 +/-20Hz as
before ?
When does your transmission start?

Subject: LF: G3XBM: 500kHz ERP increased
by 6dB - WSPR reports please
Today I modified my 500kHz antenna. The 28MHz halo up at the
top of the 5-6m vertical section (which was the coax feed to the 28MHz halo)
was removed and replaced by a spiral inductance/ top capacity hat consisting
of around around 8 "spiralling in" turns in the space occupied by the original
halo. Seeing my initial reports from M0BMU I am some 5-6dB
stronger than I was before, I guess because more of the antenna current is
in the vertical section. The measured antenna current is not much different
though.
Please listen for me on 500kHz WSPR and let me
know if I am now stronger than before.
73s
