Comment on Soldering 20m and 40m low pass filters from QRP Labs for RPi WSPR

Yeah, I don’t know how much you know about electronics but usually you want inductors pointing every which way so they don’t magnetically couple, but looking at the circuit and the tolerance on the entire thing I guess it’s fine, this saves a little space.
I usually play in speaker crossover land (exact same concepts and circuits, low pass filter, high pass filter, etc) and get a little OCD sometimes.
