Re: Spider Warfare 101: Fine Offset Edition

And what did you do to assure the critters can't enter the portals where the rain drops fall into the tipping buckets?

Re: Wind readings quite high after battery change?

Thanks Alan.

Upon further review ..... an ohmmeter on a spare sensor I have does indeed reveal that there are 2 pulses/revolution.

Interesting phenomenon.

Thanks for blowing the cobwebs out of my gray matter. :bash:

Re: Wind readings quite high after battery change?

The anemometer rotor generates two pulses per revolution, perhaps it was previously only one, or now the reed switch has some "contact bounce". But these are basically "mechanical" issues which are unlikely to be caused by changing the battery (voltage). Are you sure of that :?: My anemometer senso...

Re: WH1080 Wind speed sensor not working

My question is: If you had the wind speed sensor apart, why didn't you replace the "Chinese crap" with a "good English bearing", rather than putting a band-aid on it :?:

Re: Wh1080 rain fall problem

Don't rule out the fact it could be as simple as a flaky phone jack on the transmitter. Those connectors sometimes get damaged if the plug might have been installed incorrectly.

Good luck.

Re: Wh1080 rain fall problem

You could easily check the sensor assembly at the plug, putting an ohmmeter across the two leads and rocking the buckets to see if the switch is closing and opening. That's where I would start in isolating the problem. If you don't have an ohmmeter and the knowledge on how to use it, sorry I'm no he...

Re: WH3080

Thanks everyone for all of the information spewed forth. I had never thought about how the rest of the world sets their clocks and calibrates their oscillators. Yes, there is a 60 KHz station at WWV although I have never had a receiver that tuned that low and it would probably not matter as the QRN ...

Re: WH3080

Any idea what frequency the Fine Offset units have their ears tuned to? 2.5, 5, 10, 15 or 20 MHz? The reason it's listening to a station in Germany or elsewhere is all about radio wave propagation. Some times I can hear WWV in Ft. Collins, CO (300 miles away as the corn flies), other times I can hea...

Re: WH3080

Since then it has worked fine except for the RCC which will not connect. Any ideas what to try? Hi Ron, :idea: Try to be patient, there is not 24-hour radio propagation, and it may take a while to receive a strong enough signal to set the clock. From the WH-2080 manual: RCC reception may take a cou...

Re: No wind speed data being recorded

Hi evo1966,

I would start by testing the wind speed sensor with a ohmmeter across the leads after unplugging it. Spinning the cups should show a switching from 0 to infinity at a frequency equal to the speed of the cups.

Good luck.

Hi Steve,

Don't you mean 22.5° ? (360/16)

Perhaps your wind direction sensor and/or wiring from it to the transmitter is fubar.

Hi henkg,

I like your design and ingenuity.

How about adding another elbow to your BOM and making it undeniably waterproof ?
