Re: LF: LF daylight test close to the north hemisphere solstice

Hi Luis,

Maybe use two transformers in series, just to rise the isolation voltage 
and reduce the capacity between PA and antenna further :-)
BTW on MF you can make some TA crossings during this time of the year, 
along the grey-line, which is just a short time period. It worked many 
time in the past for me.
Worth to ris ethe TX percentage to something close to 100% for that 
short time period ( ~ 30 minutes maybe).
Good luck.

73, Stefan
