ODENThe Old Dominion Emergency Net (ODEN)


The Old Dominion Emergency Net (ODEN) is a Virginia Section ARES and RACES, statewide, communications network consisting of one or more discrete HF nets. ODEN exists to provide backup communications during an emergency for the Commonwealth of Virginia, ensuring statewide emergency interoperability between:


  • The State Emergency Operations Center (EOC)
  • The EOCs of the Counties and Cities of Virginia
  • Virginia hospitals and other designated medical centers
  • State and Federal Government agencies deployed to support the emergency
  • Non-government agencies supporting the emergency 
  • Ham stations representing the National Traffic System 
  • Others as required


During an emergency, ODEN and three Section-level HF NTS nets -- the Virginia Sideband Net (VSBN), the Virginia Net Early (VNE), and the Virginia Digital Net (VDN) -- come together to form four discreet HF nets known as the ODEN network. These nets, ODEN, VSBN, VNE, and VDN, become ODEN/A, /B, /C, and /D respectively during an emergency as indicated below.


Net Name

Dial Frequency / Mode

Purpose (can be tailored as required for the emergency)

Net Manager



Primary: 3947 kHz / LSB
Alternate: 7240 kHz / LSB
Principle command net to be used to pass operational traffic between the State EOC and the city/county EOCs, and supported agencies; can be used for other purposes (i.e., H&W traffic, logistics, etc.) if operations permit. K3EP



Primary: 3943 kHz / LSB
Alternate: 7248 kHz / LSB
Overflow for ODEN/A. Can be used as (1) hospital and medical support net, (2) logistics net, (3) H&W traffic net, as required.



 (CW Mode)

Primary: 3577 kHz / CW *
Alternate: 7050 kHz / CW
H&W CW traffic net.  * Note: As of 5/10/2016, the dial frequency has been moved down 1500 Hz



Primary: 3579 kHz / USB
Alternate: 7050 kHz / USB

H&W digital traffic net; can also be used for logistics and/or medical support net.

Primary H&W traffic mode is OLIVIA (USB, 4 Tones, Bandwidth 500, & 1300 Hz offset).  Actual RF Frequency is: 3580.5 KHz OR 7051.5 kHZ

Alternate modes include PSK31, MFSK16, and RTTY USB with an nominal offset of +1500 Hz. Actual RF Frequency is: 3580.5 KHz OR 7051.5 kHZ

NOTE: We will always move up (i.e., to 1600 Hz or 1700 Hz offset) for QRM.


NOTE 1: All posted frequencies are the dial (center) frequency.

NOTE 2: Both the /C and /D nets can operate at the same time without interference.

Training on ODEN


ODEN/A (SSB) and ODEN/D (digital) meets twice a month as indicated below to issue training announcements, practice net procedures, pass real or exercise traffic, and test propagation throughout the State for emergency preparedness.  When checking in please give your call, name, ARES/RACES appointment (if any), and if you are using any kind of emergency power, please so state and how long you can operate. We encourage all licensed hams to participate; you do not have to be a member of ARES or RACES to check-in.


ODEN/A 3947 kHz LSB  (Voice)
1st and 3rd Mondays of each month at 1830 hours local 
ODEN/D  3577 kHz USB (BPSK-31 +1500Hz) 2nd and 4th Mondays of each month at 1830 hours local


We are always looking for backup Net Control Stations to make sure the net always runs when scheduled! If interested, either as a full time NCS or as a backup, please contact K3EP .

If the Net is scheduled to run and no NCS has shown up (they may be delayed in traffic, have a family emergency, be held over at work, etc.), then you are encouraged to step in and run the net. The script is appended below.

(Each NCS may vary the script as necessary)

ODEN was established by the VA Section Manager in 1997 as an ARRL Section net
and remains a valuable ARRL resource. Use it!


Adjacent State/Section Emergency Nets

We all know emergencies do not recognize state boundaries. So for those Virginia cities and counties that border another state, it may be helpful to monitor their frequencies during an emergency (HF and VHF/UHF). The HF SSB frequencies listed below are provided for reference purposes. The frequencies were obtained from the respective section web page and/or the ARRL database based on a listing as a state or section emergency net. However, there is no guarantee these are the current frequencies the respective state will use for a particular emergency.





Kentucky 3888 kHz 3960 kHz listed for NTS traffic net. 3995 kHz is also listed in the ARRL frequency database.
Maryland - DC 3920 kHz  
North Carolina 3923 kHz 7232 kHz is the alternate. 3927 kHz listed for NTS traffic net. Coastal Carolina Emergency Net is 3907 kHz.
Tennessee 3980 kHz Also used for NTS traffic net.
West Virginia 3865 kHz Also used for NTS traffic net.

hwnlogo Hurricane Watch Net


Given that Virginia is subject to hurricanes, the HWN is another good HF net to listen to. The HWN is activated whenever a weather system has achieved hurricane status and is within 300 miles of a populated land mass. Data is passed back to WX4NHC, the Amateur Radio station located at the National Hurricane Center in Miami. Check out the HWN web page .


Primary 14.325 MHz Normal operations
Alternate 3.950 MHz When conditions are poor
