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
