A Guide to Contacting the International Space Station (ISS) via Ham Radio

How to contact international space station with ham radio?

Contacting the International Space Station (ISS) using ham radio can be an exciting and rewarding experience.

The ISS has amateur radio equipment on board, and astronauts occasionally participate in Amateur Radio on the International Space Station (ARISS) events, allowing ham radio operators to make contact with the station.

Here are the general steps to contact the ISS using ham radio:

Check ARISS Schedule:

Visit the ARISS website (ariss.org) or other reliable sources to check the schedule for upcoming ARISS events.

These events are planned in advance, and they provide an opportunity for hams to communicate with the ISS.

Verify Your Equipment:

Ensure that your ham radio equipment is in good working condition and that you have the appropriate license to operate on the frequencies allocated for satellite communications.

Know the Frequency:

Find out the frequency at which the ISS will be operating during the scheduled contact. This information is usually available on the ARISS website or other ham radio-related sources.

Set Up Your Equipment:

Set up your ham radio equipment, including the antenna, and configure it to the correct frequency. Make sure you are using the appropriate mode (usually FM or SSB) for the contact.

Listen for the ISS:

Monitor the specified frequency at the scheduled time. The ISS typically transmits a carrier signal when it is in range, and you can use this signal to determine when to start calling.

Call Sign Protocol:

When the ISS is within range, follow the call sign protocol. If the astronauts are conducting a scheduled ARISS event, they will announce the call sign they are using.

Otherwise, use the standard call sign format: “NA1SS” (North American One Space Station).

Wait for Your Turn:

There may be many ham radio operators trying to make contact, so be patient and wait for your turn. Follow any instructions provided by the astronauts or the ARISS ground station.

Make the Contact:

When it’s your turn, transmit your call sign and signal your readiness to make contact. Keep your message brief and clear. You may have only a few minutes to communicate.

QSL Card:

After the contact, you can request a QSL card to confirm the communication.

The process for obtaining a QSL card varies, so check with ARISS or the specific guidelines provided during the contact.

Remember that contacting the ISS with ham radio requires preparation and adherence to established procedures.

It’s also important to be aware of the regulations and guidelines for amateur radio communications in your region.
