hello ok well for your stable power, we are two made small changes to this forum, we have unsoldered the small circulator MDX2 difficult, put a trace of 0.1mm wires for the moment I have no suggestions, if we find any happy info to give (pse input we use a small amplifier SPF5189Z power around 80mw)

If you look at the the picture in #360 you will see that the two first circulators have already been removed. My conclusion at that time was that it did not bring anything so I would not do that again.
but thanks for the tips,
