Hello everybody

I finished mounting munin2 and test it using MUNIN2 Update 5/5 2015 
procedure. T4 is BN-61-002 made with single braid of silvered copper and 
4 turn one millimeter silvered copper teflon isolated. The result is far 
( RL is about -8db) of  expected , despite using several values of c // 
primary and c drain to GND

Question 1: which version of schematic have you used (07/05/15) with 
power supply connect at the middle primary of L4 and L3 10T secondary, 
OR (04/12/13) with power supply connected to L3 2 x 8T secondary?

Question 2: what is the best between both versions ?

Question 3:  using analyser, what is the value of "Z" do you use to 
calibrate it ?

Thank you very much to help me.
