Area Radio Nets

EMERGENCY NETS OPERATING for Tropical Storms / Hurricanes

Amateur Radio Emergency Services (ARES) typically run emergency nets when the gulf coast (or other areas) are threatened by tropical weather on a twenty-four hour basis for the duration of a declared emergency period. Nets are generally operated on 3.873mHz (night time) and 7.285mHz (daytime). Net control operators may be located within Texas or elsewhere as band conditions warrant.

These type of Nets are normally restricted to emergency traffic only. This generally includes operators from affected Emergency Operation Centers (EOC), ARES officials, folks affected directly by the weather needing to report conditions when requested, or emergency traffic at any time. All other operators are requested to refrain from transmitting plus/minus 3khz from above frequencies.

Always listen to net control and follow directions not to transmit unless you have a legitimate reason to do so. From time to time, you may hear a request for more volunteer net controllers to work a two-hour shift. When such announcements are made and you feel comfortable in handling such a net on HF, feel free to provide your callsign and other info as may be requested. Remember that this is an HF net, and as such, you may not always hear both sides of a conversation. Sometimes the Net Control will ask for a relay of a faint or distantly heard station and someone else will jump in, identify, and relay the traffic for them.

Net Operational Guidelines - Local (VHF/UHF/220)

Following are some simple Do's and Don'ts regarding operation during a controlled (or closed) net situation, such as during a bike-a-thon, run-a-thon, or emergency situation These are general, common sense items that all operators should know and follow, without having to think much about it. Practice makes perfect, so sign up for the public service events as a volunteer and be ready to help out if another hurricane brings more unscheduled visitors to our fair city.

  • Listen to Net Control and follow their instructions regarding checking in (i.e. using ITU Phonetics for your call sign the first time, etc.).
  • Listen to your radio to monitor other operators so that you will be ready if asked for status reports from your location (i.e. if other locations are being asked about their level of supplies, check your own levels but don't report until asked).
  • Use your tactical callsign to request the attention of net control. For example, "Net Control, this is Breakpoint One".
  • Listen for an acknowledgement from net control before beginning transmission of your traffic.
  • Keep your transmission brief and to the point.
  • Break in with emergency or priority traffic if the situation warrants it.
  • Give your FCC amateur callsign at the end of your transmission.


  • Offer up any information that is not asked for, such as weather reports or number of riders passing your location.
  • Transmit your traffic without waiting for
    acknowledgement from net control. For example: "Net Control, this is Breakpoint One. We need water and we are running out of ice, and we called for a SAG 30 minutes ago and they still haven't shown up!"
  • Leave the net or turn down the radio without
    advising net control that you will be away.
  • Call another station directly without first clearing
    it with net control.
  • Lose your cool. Be prepared to repeat your message if requested by net control.
  • Secure (shut down) or leave your assigned location / site without approval of net control.
  • Forget to key up, pause briefly and speak clearly and distinctly so that the message is clearly understood despite any interference or noise.

What is a Radio Net?

Many of the area ham clubs run regularly schedule "nets" on one of the repeaters or specified HF frequency, always on the same time of day and day of week. Some run daily, others run weekly. Some folks simply get together and have an informal net that is not affiliated with any organization at all! If you know of a local net not listed below, one that is open to the public (i.e. not restricted) feel free to contact us using

THESE LISTS ARE OUT DATED. SORRY. We'll be working with some other hams to build an updated list to share with you soon.

This is just a net used by the Unusual Suspects {voice}, we just have conversation there on Thursdays scheduled and any other time similar to our activity on 2 meters. The goal is to use 6 meters and have activity there so in the even the band opens, we can make some contacts. But it is just normal conversation round table, no strict net rules or such. Open to anyone on the planet earth,

Emergency HF Traffic Nets

HamWith the advent of Hurricane Katrina and Rita visiting next door during 2005, these HF nets have become very active and very important to the disaster response efforts of this nation. Below is a list of known nets on 80, 40 and 20 meters. Some frequencies are used only in daytime and others at night. Some are used 24/7.

Be sure to listen to nets first, follow net control's instructions, and don't transmit unless you really have something they need to know, or you can handle a piece of traffic that they need to pass into your area. They don't need folks "just checking in for the count", a common practice on the local VHF 2-meter traffic nets. Please be courteous by not operating nearby the nets, frequency wise, or operator wise, to avoid bleed-over or other interference.

Emergency nets are serious business, and only the "professional" amateur need apply.

Note: These frequencies are subject to change in both purpose and frequency. Don't bother to "check-in" unless you have serious information being requested to be passed. Texas nets are highlighted with BOLD below, but these nets cover the entire area affected by Hurricanes.
