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.

Hi LF
Thank you for the reports Chris. Very interesting
I have switched to WSPR-2 as could be running Tx last night and there are more
monitors. Conditions
are getting harder but still some spots from SM3LMN during the night
Clearly the hardest time is just before sunset were sometimes I can get no
spots even from western
stations as EB8ARZ. A bit later after sunset SV8CS and SV8RV start spotting
from the east. And later
spots from northern latitudes start again
This week I should have to rework the PA output transformer. The one in use
lacks good isolation and
get arcs when pushing it a bit. All going Ok may be I can still rise some dB

Asunto: Re: LF: LF daylight test close to the north hemisphere solstice
Hello Luis,
Plenty of WSPR15 spots here, but for some reason they are not
uploading to the reporter map / database, despite restarting WSPR15

Hi LF
Apart from cheking that blacksheep is still running ;-)
Just a notification to LFMEN
I’m transmitting WSPR-2 during daylight to check conditions as we approach
summer solstice here
About 2,7A RF current normally
The PA is still down at home, so switched off at night. But then I can use the
90m vertical for RX
QRM is high but overall is a very good performer. I can report
Chris 2E0ILY with nice signals and also others which
unfortunately don’t transmit during best night hours. This reports can be seen
spotted as EA5DOM/3
There is a permanent 24/7 Rx using MiniWhip with poorer Rx spotting as EA5DOM/2
As conditions get worse during daylight I will switch to WSPR-15
and hope to get somebody reporting there in
the forgotten mode
