[Elecraft] Low power output on 10&12m

[Baker]

After successfully modifying my K2 40m Band Pass filter for the=
 EU 
band plan I decided to check the rigs power output. All was 
reasonable except for an output about 8W on 12m and 7W on 10m.
 This meant I only get about 60W out of my KPA100.

Reading the mail I came across a post about changing T4 core to 
increase the coupling efficiency at the higher frequencies.
Have folks tried it, and does it make a difference ?

The core mentioned was an Amidon BN43-302. I have searched the=
 net, 
but have yet to find a supplier in the UK. Does anyone know where=
 I 
can get the ferrite or a suitable substitute ?
