I've had a Davis Instruments Vantage Pro2 wireless weather station for 5
years and it has been flawless. I have two receiving console display
units and have never had any RFI susceptibility or emission problems
with this system. However, the sensor suite transmits on 902 - 928 MHz
in Frequency Hopping Spread Spectrum mode, not at 430 MHz as stated below.
Since the system uses FHSS RF mode, you are unlikely to *ever* detect it
on any ham receiver.
The sensor suite is powered by a solar cell which charges a super
capacitor for overnight operation. If several days without sunshine are
encountered, the unit includes a Li primary cell as battery backup. My
system includes a 24-hour fan-aspirated radiation shield powered by its
own solar panel and NiCd cells.
These systems do require at least annual maintenance so they should be
accessible for service. In particular, the tipping-bucket rain gage
needs its conical collector and the buckets cleaned as they accumulate
dust and dirt. There is a recent version of the collector funnel that
has a better filter at the bottom and has bird-repellent spikes. Since
my aspiration fan runs 24/7, the plastic louvers that make up the
radiation shield also need cleaning once a year.
I had a previous wired Davis system for 25 years so I now have some 30
years of accumulated weather data stored on the connected computer. I
never had any RF problems with either of these Davis Instruments
systems; both performed flawlessly!
Now, granted, some will say we don't have "weather" here in Los Angeles
(I live near Disneyland). Historically, though, we do get *some* rain
and often have wind with gusts to 70 MPH where I live. I've seen
relative humidity values as low as 5 % during a "Santa Ana Wind."

I've had the Davis Vantage Pro II wireless for the past 3 years. Very
reliable and rf quiet. It Tx around 430Mz but I've never heard it or
recognized it on hf or vhf..
