It's very easy, if you have programmed the Emergency beacon into a
programmable memory.

How do you know that your emergency packets are being gated correctly? That
something isn't misconfigured somewhere else (like GPS type, etc.)? There
are many variables that you can't check if you make changes between
configuration/testing and storage. This is why ELTs can be tested (at the
top 5 minutes of every hour? can't remember), air raid/storm sirens are
fully activated for testing, fire departments across the country open the
station speakers to test their equipment, etc. You want to test the
equipment in the exact configuration in which you plan to use it when "the
Big One" happens, then lock it down that way... I would also advocate
publishing a notice that you will be testing your emergency packet on-air
on this list, but you must remember that not all APRS users are subscribed
to the mailing list (in fact, some probably don't have Internet access at
all and use APRS strictly via RF).

For those using APRS+SA, there is a built in little "calculator" trick to do
a reverse DNS. From the APRS+SA calculator, enter the follow:
#ni 'GetHostByAddr' ip
Examples:
Enter:
#ni 'GetHostByAddr' '12.216.133.184'
Returns
0 0 12-216-133-184.client.mchsi.com 2 4 12.216.133.184
Enter:
#ni 'GetHostByAddr' '12.209.105.2'
Return:
0 0 12-209-105-2.client.attbi.com 2 4 12.209.105.2
A forward DNS can be done as follows:
#ni 'GetHostByName' URL

And that's easier than changing the font in the mail reader? That's why
people seem to think they need to send e-mail in HTML. A simple font
change would fix it.

Didn't I read somewhere that Microsoft had or was about to drop support

That is not a wise thing to do. In fact, that is quite unwise.

Send a normal packet. If it gets through, then so will an emergency one.
THe difference is only 1 bit.

You can test your D7/D700 configuration any time 24 hours a day. Just
dont set the EMERGENCY flag. ELT's only transmit emergencies, thus they
cannot be easily tested.

It operates normally just like during an evemergency. If it transmits
with a normal message, it will transmit with the EMERGENCY flag set.

Testing EMREGENCY packets on 144.39 should never be done. ever.
Not everyone will get the word and it only takes one person (out of the
10,000) that might see your message to call the cops and make a nuisance
out of the whole deal.

It was within the last year that someone on this list found someone using
the "EMERGENCY" beacon while on a search and rescue mission. I don't
remember the details.
If the Emergency beacon is going to be viable as a call for immediate
assistance, it needs to be spelled out in BIG BLOCK LETTERS on all
documentation what the proper use of it is. This list has the cream of the
APRS crop on it. There are a lot of people out there that don't have a clue
about how APRS operates and they are using it.

Bob brought up some points when I was going to test my station, set it for
something like priority or special, the station shows up but dose not
trigger alarms all over the world. I have done this on my D700 or the D7 OFF
the normal aprs freq and it works just fine. I have been in ham radio for
now over ten years and public service trained as well. NEVER use emergency
unless it involves IMMEDIATE property or life threatening injuries. The
thinking that setting a beacon due to the fact that you may be involved in a
emergency drill (real or not) is no reason to set one if your or someone's
life is NOT in danger. The thinking that this is monitored all over the
WORLD gives some scope to how many listeners are really out there that may
not be transmitting but are keeping up on local and global stations. Most of
the training that I have seen has stated that equipment capable of using
this beacon (be it man down alarm, emergency beacon, etc) should be used
only when YOUR life is in danger. But then that is coming from a
firefighter/EMT training as well.
Just my thought on the matter.
Dakota
