For the system blue H-field pre-amplifier PCB - a few questions:
1. Do the ferrites connect between just the a and b ports with the ground port left unconnected unless additional shielding is needed?
2. Is there any polarity to the ferrites - I see references to one enameled wire with a knot being + or is this for the old system only.
3. For ferrite antennas do the PCB jumpers need to be soldered (closed).
Thanks in advance!
