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.
