AWOS - Automated Weather Observation Systems

Is the All Weather Inc. AWOS certified by the FAA?

Yes! You can download a copy of the AWOS 3000 certification letter here.

How long does it take to get an FCC approved frequency for VHF radio transmitters or UHF data link radios?

Approximately 6 to 12 months.

What types of connections are allowed between the DCP and CDP?

Depending on the distance between the DCP and CDP, the customer may choose RS-232, RS-485, or UHF radio connectivity.

What is the output power rating for AWI's VHF radio transmitter?

AWI's VHF radio transmitter has a 5 watt output.

AWOS reports all data missing, what do I do?

Reset the PC and the peripheral Interface and see if it comes up. Make sure the breaker for the DCP is not tripped. The display inside the DCP should be ON and you should be able to scroll up and down using the keypad. If the AWOS is using UHF radios for data link, make sure the transmit and receive lights are flashing. If the AWOS is using a landline for its data link, make sure the voltage is changing every 5 seconds on TB4 -9 & 10.

Sensors

What are the power requirements for AWOS sensors?

Power requirements for AWOS systems are detailed in our site preparation manual. You can download the site preparation manual specific to your AWOS level here.
