ARISS Packet System

ISS is now digipeating packets via the UNPROTO call of NOCALL.
Uplink is 145.99 and downlink is 145.80.

Here is how to operate via ISS!

1) Do not attempt a connection to any other station. It is a fruitless exercise and only adds QRM to a very busy channel.

2) ANY TNC:

Set UNPROTO to CQ VIA NOCALL.
Then go to converse, and TYPE greetings or messages to others that you see on the downlink...
If you see your packet digipeated via NOCALL, so did everyone else...

3) Kwd D700 or D7(G):

Set one of your program memories for this application.
Set data TX on band B to 145.990.
Set data RX on band A to 145.800.
Set packet to 1200 baud.
Set path to NOCALL.
Go to MSG GROUPS and add the wildcard "*" to the list so you can see messages to anyone. Operate normally. (D7A users see below)..

4) APRS:

Turn off ALTNET filters.
(In APRSdos set CONTROLS-FILTERS-OTHER)
Set unproto path to NOCALL.
Set radio to transmit on 145.99 and receive on 145.80.
You can send messages to anyone you see.
Once you see your message digipeated in the downlink, so did your intended recipient. Do not expect an ACK.
Go ahead and erase the message to stop it from adding redundant QRM to the channel

SHARING THE BAND.

If you see your OWN packet digipeated (MY PACKET) then everyone else in the country also saw you, so no need to repeat that packet for at least 2 or 3 minutes.

ARISS packet system to be activated

* ARISS packet system to be activated: The ISS Expedition 1 crew was
expected to turn on the packet system sometime this week. The Amateur Radio
on the International Space Station packet system will identify as RZ3DZR-1.
It will uplink on 145.99 MHz and downlink on 145.80 MHz. When the system is
activated and the ISS is within view, Earth stations can expect to hear a
periodic beacon every two minutes. Earth stations may send unformatted
informational (UI) packets to the ISS (ie, it should be operational for APRS
beacons). Earth stations are asked to refrain from using the Packet Mailbox
System at this time, however, since the crew does not have the computer
hooked up to read messages. Do not transmit on the packet uplink until you
have heard the packet beacon. If you copy the packet system, let ARISS know
and save your information for a future QSL card. For more information on
ARISS, visit the ARISS Web site, http://ariss.gsfc.nasa.gov/ .--Frank Bauer,
