I got around to moving the 1w from the MacArthur Hat, with the 1.6k resistor, to another GPIO pin with a 4.7k resistor between this GPIO pin & 3.3v & the spiking has, almost, completely disappeared.
I get a very occasional spike, once per day or so, on only one (the longest, 3m, run) of my DS218B20 senders.
