3. What is Digital Communication
ANY information that can be digitized can be sent via a digital mode.
Some data is just too big to reasonably send via sound card digital modes (Video, MP3, big pictures) etc.
We will be focusing on smaller file types: text, spreadsheets in .csv format, small pictures.

4. What is Digital Communication
Best Used for:
Specific directions / instructions.
Long lists of information.
Difficult to spell names.
Prescriptions.
Etc.

Short, tactical messages.

8. Why Digital ECOMS
Accurate, Rapid Communications

9. Why Digital ECOMS Think back to your last public service event,
drill, or deployment.
You probably passed a lot of traffic best suited
for voice communications but...
What if you had been asked to pass:
Roster of evacuees
Required prescription medications
Directions to a disaster scene

10. Why Digital ECOMS The needs of our Served Agencies have changed.
They still need voice communications but...
There's an increasing need for data communications.
We need to be able to provide more than just voice communications from a ham with an HT.
