I've discovered that the problems we've been experiencing on our Instromet
weather station with regards to spikes in rainfall and windspeed data is due

down, but one solution I've read is to fit a ferrite? to the serial cable
connected to the PC.

Does anyone else have experience of this sort of interference and, if so,
what solutions have you found?

RF interference is well known to radio hams.

Despite having held a licence for 30 years, it's a long time since I
fired up a rig!!!

ISTR that 2 or 3 turns through a "donut" ferrite coil was the starting
point to curing RFI, although that may impact on the wanted signals if
the baud rate is high enough.

Very much a "suck it and see" game with RFI I'm afraid.

Good luck
