A lot of state EM agencies are actually improving their HF capability, MARS is rapidly becoming the operator of choice for state governments and have units that can deploy with other agencies such as State Guard units. Winlink RMS is a popular resource for setting up in the field with the ability to send and receive email traffic. You may hear some HF-ALE associated with OEM activities.
