Bonnie,
Here is my experience with mobile messaging with Pskmail. This was
done on HF NVIS but I believe the concepts are independent of the
radio link method (HF or VHF). My background is four wheel driving in
the Australian Outback and keeping a track log of my position a well

Well, let me see.
2m/70cm D-star radios can communicate with each other without a
repeater. These radios can send audio and slow speed data
simultaneously. The slow speed data can be displayed on the radio's
screen or on a laptop connected to the radio.

Here are some possibilities:
1. Teams have their radios on all the time, or perhaps only on the
top of the hour for 10 minutes to check in - so their welfare and
status is known and for delivering any important messages.

seen that actually addresses the core issues.
Certainly, your item 1 suggestion, have their radios on all the time
is a necessary fundamental for push messaging to work, and it is the
prerequisite for it to function.
Bonnie,
While your question has been answered quite well by several of us, the
main thing to keep in mind is that if you are going to use amateur radio
communications, both stations must be operational and within range.
These kind of communication must be done with tactical phone for
The core question still remains:

mobile or portable operator in the field, when
the field operator has no expectation that a
message will be sent?
Or, even more simply, how can we timely notify
the field operator You Have Mail via HF?
