VOLMET Quick Tune SDR List

VOLMETs fixed stations in the aeronautical radio service, tasked with broadcasting weather for aircraft on long distance flights, out of range of typical VHF aero weather sources. They often operate on an hourly schedule, sharing their frequencies with other VOLMET stations. Items broadcast by VOLMETs are typically lists of routine airport weather observations (METARs), forecasts (TAFs), significant weather warnings (SIGMETS), and sometimes pilot reports (PIREPS). To learn more about these aviation weather reports and forecasts, visit the Aviation Weather Center. There is a lot of very careful and specific language in aviation weather data. For example, "Runway visual range" and "visibility" are two different measurements, as "mist" is different from "fog" and "probability" is not quite the same as "chance of..."

Use the list below to quickly tune in the VOLMET stations you wish to monitor. Simply click on the station and frequency, then wait for the SDR to render in a new browser tab. If signals are weak or noisy, try another frequency or switch to a different SDR server. Also, visit the VE3SUN KiwiSDR List to find other receiving stations in your geographic area of interest.

Since propagation conditions vary between different receiver sites and frequencies, try different combinations to find which ones work best for your desired stations. Most KiwiSDRs have rather high default gain settings, producing plenty of noise, which can cause listener fatigue. Consider to, reduce the AGC threshold to a setting between -85 and -90 dB. The KiwiSDR default USB filter bandpass is good VOLMET traffic, though the URLs given hers set a wider bandpass for better fidelity. VOLMET stations operate with precise, dead-on tuning.

Avoid opening multiple SDR tabs from the same site at one time, as some SDR servers with detect and block users who draw excessive bandwidth. Also, having too many SDR tabs open will consume high memory and CPU capacity on your computer, causing choppy reception.

If you find interesting signals on the VOLMET frequencies, give some thought to making an audio recording or screen capture video to share on sites such as YouTube or Soundcloud
