For voice communications, 28 bits would be beyond overkill.
Even for music, while someone might put up a point-to-point microwave link or

If the bit rate is faster, is not the signal wider as well?
You can trade off bit rate either for bandwidth or the signal-to-noise ratio
required for reception, which effectively means range for a given power.
There are

OK, but there's nothing wrong with extending the current protocol and calling
it D*Star+ or just D*Star Compatible or whatever.

[Regarding your exercise]
A local hospital here in Denver suffered an actual loss of
their internet connectivity during the day of the exercise and was unable to
enter patient data from incoming casualty patients because they couldn't

Hi Charlie,
We also see this time and time again even
in simulations where the professional emergency services have trouble
with their communications, their systems become overloaded, and there's
things that need to be communicated that aren't central to their
important tasks.

Hi Charles,
I suspect you're correct that your request was
probably kicked around a fair deal with no one really taking that much
time to read and understand it, but in the end I agree with the
response your were given. I think you're suffering from the problem

Hi Bob,
I have to seriously question whether D-STAR should ever
be used for applications similar to what you've noted
one can do with a mobile that is on an EVDO or GSM network
or WiFi enabled.
Well, people always think up interesting new applications, and while the
various parameters of a
Hi John,
These are good comments and I generally agree with them. I'll add a few
thoughts of my own here...
1) a 'glass cockpit' style of interface - an LCD that is either itself
touch sensitive or is surrounded by softkeys, or both.
Note that the IC-2820 already has a large, dot-matrix LCD
Hi Chuck,
Good points. Although I think the likelihood of a (successful) large scale
attack on the Internet itself is quite small compared the myriad of natural
disasters we have every year, it certainly it worth thinking about and planning
for. At some point I think you're just back to HF
