air-core loop connection to H-field preamplifier 23.1

[GeezerD]

I've wound my loops, and found the wiring diagram for the preamp at https://docs.lightningmaps.org/hardware/...tors/mini/.

Is proper for me to simply hook up my two unshielded loops to H1+, H1-, and H2+,H2-, respectively, without any soldering on the preamp board?
A screw-connection header is already soldered to the board.

Other preamp instructions indicate that pairs of solder pads on the back of the board are to be bridged if an air-core loop antenna is used.
The solder pads appear to be present on the 23.1 preamp board, but no mention is made in the instructions about bridging them.


(I'm not posting from the account I registered when I got the URL from booting up Blue Mini on my home network: I'm pretty sure I know how I broke it and I can't fix it in the short term:  I am dellel, station 3147, if my bone fides are required to get an answer).

I spent the day getting set up: debugging the connection to the very economical Bingfu GPS active antenna, 
www.amazon.com/Bingfu-Waterproof-Navigation-Connector-Tracking/dp/B07R7RC96G
The baud rate turned out to be pretty important for the 1 Hz GPS signal: anything less than 460800 would fail to lock it, 
and a view of the overhead sky is best for it: a south window simply would not do.

thanks for reading

It seems like no bridging is needed for those pad jumpers. It's working fine without it.

Yes, if your 23.1 preamp board already has screw terminals, you can connect your two unshielded loops directly to H1+/H1– and H2+/H2, without soldering.

Do not bridge the solder pads on the back unless the documentation for your specific board version explicitly says to, the 23.1 board doesn’t require bridging for air-core loops.
