Chad,
You reversed the situation. At your home location you undoubtably had many
callers which you never heard (like the EUs not responding to your calls
this year). They were running HP with RX limited situations like you do at
home.
The order of magnitude of change is probably ~30 dB, or even more depending
on the difference of the RX at the two locations. You gave up 12 dB right
off the bat with the TX differential.
The end result is tremendous, and what you experienced replicates what we
experience all the time from the deep Southwest. In this contest the most
spectacular example was me calling one certain OM station for a full ten
minutes. During that time he worked 3 stations on the USA east coast and
the rest of the time he just CQed in my face. His signal did have QSB but
most of the time the signal was solid Q5.
I have been told by those who have personal on site experience that much of
the eastern EU area has power line interference problems. This expereince
is not isolated as it is regular, contest to contest from our part of the
country.
Mis dos centavos.
