Re: LF: EbNaut at 8270.01953125

Hi Paul, VLF 

This afternoon I've added some aluminium tubes to the counterpoise obtaining an appreciable reduction of losses. I try again with 560mA (but using 240W out, 40W less than last transmissions), same parameters, start time: 18:30 UTC.

Thanks again for reports.

All the best
