Thanks Richo,
I'll start with a 60cm diameter, 12 turns.
Hope I'll be soon at position 1 in blue queue

Just received my Blue. I just want to verify my understanding of the jumpers for the ferrite antenna. If ferrite, I do NOT solder the jumpers? Solder only if using Loops.

Correct.
Oh pooh "correct" is too short an answer!

Is it +1 and Ground or +1 and -1. The pattern will be the same for ferrite 2... My signals seem all to have a +0.04v bias to them, both on the E and H signals. My station is 1691. I do have the proper shielded cables.

Loops or ferrites connect to the + and - terminals on the preamp.
A small positive offset of a similar size on all channels is a normal "feature". Mine is +30 mV +/- 10 mV.
Occasionally Ch1A will jump to -190 mV but this isn't reflected on the controller status pages. However I have just noticed that it is included in the strike data uploaded to Blitzortung.
