RE: Email Via ISS...

A probably too detailed and oversimplified explanation of the technique
follows, beginning with a message to an individual amateur station, then a
BLN to all, and finally one-line EMAIL from RF.

Sending Messages from a packet terminal program

To send a packet to the local APRS Internet Gateway (IGate), QSY to
144.390Mhz in North America (or for a satellite, the uplink freq).
With your TNC in Command MODE (cmd: prompt showing),
Set Unproto APRS via WIDE2-2 (u aprs v wide2-2).  For a satellite use it's
digicall instead of WIDE2-2.
Put your TNC in CONVerse MODE (instead of Command MODE) by entering "conv"
or "k"

Later, when you're done, you'll want to enter a <CTRL-C> to return to
Command MODE, and change your Unproto back to only CQ (u cq) and make sure
you're set to Beacon Every 0 minutes (b e 0).

But now, while in CONVerse MODE (conv), anything you type is transmitted
(one time only) when you hit Enter, or whenever the text line buffer limit
(PACLen) is reached.
If you're watching your screen after you transmit the line by hitting Enter,
you should (hopefully) see a copy (or two) of your packet being
retransmitted from the local WIDE APRS digipeater (or satellite).  If not
(your station may not be hitting the digipeater); you could go back to
Command MODE long enough to try an alternate digipath, Unproto APRS Via
RELAY,WIDE (u aprs v relay,wide) if needed.
Understand, Not every packet will get through in CONVerse MODE, so you may
have to retype and repeat transmission of a line once or a couple times to
hit the digi.

The format for an APRS message is shown below.  Just type this in the data
portion of your packet (type the following text, then hit enter):

:xxxxxxxxx:message goes here {n .

Bob Bruninga WB4APR says that ":xxxxxxxxx:" is a fixed-length nine-character
'TOCALL' field padded with spaces and bracketed by colons. It ends with a
line number preceded by "{".

An example without the line number (needed for more than one line) at the

:WA8XYZ-14:message goes here..............

Where you begin with a colon, then a 9 byte callsign (padded with spaces as
needed) to whom you are sending the message and then another colon in the
11th position and then the message.

The only problem is that everyone running APRS software or with a Kenwood
APRS HT or mobile will not get this packet except for WA8XYZ-14.  A better
way to communicate with other APRS stations, more than one at a time, is to
send a bulletin (BLN).  Bulletins are captured by everyone using APRS.  In
this case, use the format:

:BLN1     :bulletin text goes here...............

Remember there should be nine characters (padded with spaces) between the

This packet will be captured by ALL aprs stations, including the handhelds
and mobiles (and any IGates or SATGATEs that are monitoring the downlink and
feeding to http://www.findu.com).   Use a different # for each bulletin so
that they do not overwrite each other on receipt. (BLN1 thru BLN9)

Or, if you REALLY WANT to have fun, send an APRS message in this format:

:EMAIL    :wb4apr@arrl.org Hi via Ham radio and the ISS, etc...
:EMAIL    :abcde@fghij.com Text begins here using one line only.

This APRS message (if received by any IGate station, anywhere) will be
captured by the APRS system, converted to an EMAIL (by the WU2Z server in
New Jersey) and EMAILed to the EMAIL address in the message.  Note, a valid
EMAIL address must be the first WORD of the message...  and all the message
must fit on one line...
The word EMAIL must be in upper case (capital letters).

If you watch your terminal screen, you _may_ see the automatic
acknowledgement packet from WU2Z go by (something like):

WU2Z>APM352,TCPIP*,qAC,WU2Z::WB4APR   :EMail message delivered OK{100

Of course the easier way to format these messages is by using APRS software
instead of only a terminal program.
Good luck!
