Dear Don,
Just did check the dummyload with an MFJ analyzer and is working fine on
160m and higher.

Dear Don,
Thanks for your support!! there is a deep and sharp null for all bands
except 80 &160m, cannot get lower than 1.3 for 80 and 1.8 for 160, I did
check the core and it is the large dark gray core. I also removed T4 and
did check the solder connections. No difference in results.
Maybe askin
Koert,
The absolute minimum voltage found in the C1 null (as observed at TP4)
is not as important as the depth of the null.
If you cannot achieve a deep and rather sharp null, there is something
wrong with either T4 and its associated components or with your dummy
load. The actual voltage a

Dear all,
Please find my emails to Elecraft support below. Is there maybe somebody
Dear Koert,
It probably isn't the problem, but you might check that the core
used for T4 is really an FT50-43. The wrong core might not have enough
permeability at the lower frequencies.
