In a gap between showers I changed the wiring over so that the cap is now between Counter A and GND.
I also swapped the electrolytic 1uF for a polyester film 100nF, and bumped the resistor (still between anemometer and counter A) up from 1K ohm to 10K ohm to compensate.
The low pass filter now seems to be working as intended, and the vortex is giving very reasonable results (Average just a fraction over the WMR928 lower down the same mast. Gust 'better' than the WMR928, but quite reasonably so).
Naturally I'll keep monitoring, but I think this is the solution!
