    The Amateur Radio Daily News Service at http://www.southgatearc.org/ has links to half a dozen stories about the involvement of Radio Amateurs in supplying emergency communications in the aftermath of hurricane Katrina.

    Our thoughts are with all those who have suffered in this disaster.

    The following from Bob WB4APR. New reports of Amateur operations in the aftermath of Hurricane Katrina at http://www.southgatearc.org/ 73 Trevor M5AKA
    ----
    USING APRS SATELLITES IN DISASTER AREAS:

    DISCLAIMER:
    This document is NOT a recommendation to
    use APRS via ISS in a disaster.  There are many
    other Ham Radio Communications capabilities that
    are better under any given circumstances.

    This document was only written to tell "HOW"
    to use APRS and packet via ISS for emergency
    operations in a disaster area,*IF* such use
    was necessary for a given emergent need.
    ---------------------------------------------------------

    This email describes how to use the ARISS and
    possibly PCSAT2 system (on ISS) for tracking and
    communicating with APRS assets in the Hurricane
    affected areas.  It covers 3 topics:

    1) Knowing when the ISS is in view without a PC
    2) Settings for ISS and PCSAT2 digipeater
    3) How to send an Email from your APRS or
       D7 or D700 APRS mobile/HT or normal packet.

    KNOWING WHEN ISS IS IN VIEW:

    DAILY 1:  At 30 deg latitude (New Orleans),
    you will get two contact window periods a day
    and each period will give you 2 or 3 pass
    opportunities.  Today these Windows are 7-10 PM
    and 2-6 AM daylight time (applies everwhere at
    this N.latitude).

    DAILY 2:  If you hear a pass early in a window,
    then you will hear another one 97 minutes later.  
    And if lucky, another 97 minutes after that.

    DAILY 3:   Similarly, if you hear a good pass during
    the first window, then you will hear another good
    pass in the second window exactly 8 hours
    (and 2 mins) later.

    NEXT DAY:   If you hear a pass on ONE day, then
    you will hear another one the NEXT day  27 mins
    LATER.  (AND/OR 68 minutes EARLIER.)

    MULTI-DAY:  For longer range multi-day planning,
    these "window-periods" slide EARLIER by 22
    minutes per day (but the exact times follow
    only the "daily" rules above")

    WIth these simple rules and keeping a log of
    when you hear ISS passes on your dashboard,
    it is easy to predict future passes and operating
    times for weeks or longer.  You can work up
    simple plans like this for ECHO, SO50 and any
    other satellite.

    NEW-START:  If you are starting new, then all you
    have to do is monitor continuously during one
    of the windows until you do hear a pass, and
    from then on, you can figure your own schedule.
    Just remember to slide the window earlier by
    22 minutes per day from the times above for
    1 Sept.

    SETTINGS:  There are two digital assets on ISS
    and both digipeat using the path of "VIA ARISS"

    ARISS:     145.800 down, 145.99 up
    PCSAT2:  435.275 +/- 10 Khz, 145.825 up

    Use ARISS in the disaster area and mobile
    since it is 10 dB stronger, has 9 dB less path
    loss on the downlink to other omni's, has more
    IGate stations and has no appreciable Doppler.

    PBBS:  If you have a portable cross band beam
    antenna,  and can remember to TRACK ISS, and
    point the beam, and tune the downlink for Doppler,
    then you are welcome to use the PCSAT2 BBS for
    longer paragraph type trafffic, though you
    must remember that maintainig a "connection"
    via a satellite is problematic at best.  The PBBS
    callsign is MAIL.

    Only USA STATIONS IN the disaster area
    should logon to the BBS with emergency
    or priority traffic.  No other USA stations should
    attempt to use the BBS for ANY purpose even
    emergency or priority traffic to or from someone
    in the  disaster area.  

    Instead, Let stations in other parts of the world
    be the gateways for downloading any such traffic.
    or sending back replies.

    EMAIL:   APRS is a one-line message system.  
    But you can send email if you can fit the email
    address and text in the same line.  ANyone
    can do this via ISS using the APRS protocol
    if they have either an APRS system, a D7 walkie
    talkie or a D700 mobile, or even a simple radio/TNC.

    EMAIL FROM APRS, D7 or D700:
    - Set your path to go via ARISS
    - Send the message line TO "email"
    - Make the first part of the message be the
    email address and then enter your very brief
    email text continuing on the same message line.
    For any TNC or packet system, simply make
    the AX.25 address be APRS and send the
    packet as a UI digipeated packet via ARISS.

    If you are successful via ISS, your radio will
    display "MY MESSAGE" to confirm the packet
    got digipeted.  If it did, then cancel the
    remaining message retries to reduce QRM.
    Do not expect a message ack.

    EMAIL FROM ANY PACKET SYSTEM:
    To do this you must make your packet look
    like an APRS message packet:
    - Set your UNPROTO APRS VIA ARISS
    - Go to converse
    - Type :EMAILssss:eeee@eee.eee.eee text
    Where the four "ssss" are four spaces
    Where eeee@eee.eee.eee is the email address
    Where text is your text.

    If you see it digipeated, then your email will
    probably be successful.  If not, you have
    to type the whole thing again, error free
    to try again.

    CONCLUSION:
    This document is *NOT* a recommendation to
    use APRS via ISS in a disaster.  There are many
    other Ham Radio Communications capabilities that
    are better under any given circumstances.

    This document was only written to tell "HOW"
    to use APRS and packet via ISS for emergency
    operations in a disaster area, *IF* such use had
    any immediate application.

    But in any case, unattended packet beacons via
    ISS are NEVER welcome  and especially over the
    USA at this time.

    This email is provided for what-it-is-worth, and
    is not endorsed nor approved by ARISS at this
    time.  I just thought it would be useful to have
    it as a baseline...
