Emergency voice communications has it's place, especially UHF and VHF short haul, in support of the responding agencies. We, for example , often support Search and Rescue teams in the field, using VHF and often GMRS., and often the served agencies system as well. We are not limited to ham bands only. While a radio log is kept of all transmissions and incoming messages, the log is a summary of the trafic, not the exact, word for word of the message.
Where digital comes into play is passing formal traffic between sites, when radio system are overloaded and we take up some of the traffic. These by nature are formal written traffic, often technical in nature which requires word for word transmission, and formal message handling skills on the part of the hams. For those of you who have done formal traffic under less than stellar conditions, this can be a very laborious process. This is why we have gone to developing digital comms from our command post, and at the local EOC, so that formal traffic can be passed as fast as the typist can go. we are set up to use VHF, and HF as required since we service a large area where 80 and 40M would be effective , up to a range of 500km . This is not "long haul" but enough to be a challenge. Most long haul traffic would be formal messages as well, and digital modes coould certainly make that exercise less painfull. Digital modes in the recovery phase of and incident would also be practical, handling the often overwhelming volume of health and welfare traffic. What would really be great would be an easily established gateway between a digital mode and the internet to pass off messages on the form of email, besides the Pactor 1 2 3 that is currently available. That is one item on my wish list right now........

However... in a real emergency where help is needed right now, it is far more likely that communication could be established by SSB voice operating from a car or other makeshift location. Digital modes require a computer and someone on the other end who is similarly equipped, and that's a bit much to ask in a real emergency. Once the immediate need has passed and things settle down, digital may have its place. To sum up: Get on the mike and start hollering. SSB voice will be much more likely to be heard and replied to, in my opinion. This could change in the future but for now, that's how I see it.
