Participate in the 5th Saturday Drill, January 30, 2016

The next 5th Saturday exercise will continue to support the Cascadia Rising Catastrophic Earthquake Exercise (CR-16). The exercise period is from 9:00 – 12:00 hours on Saturday, January 30, 2016.

Update #1: The command channel will be on the Columbia Center repeater (444.550+, tone 141.30). Please monitor that frequency for information during the drill period.

Update #2: If you are able to send and receive WINLINK messages and would like to participate on Saturday:

  1. Call in on the KOMO repeater at 8:30 AM on Saturday for instructions, 444.425 plus offset 141.3 tone
  2. If unable to reach KOMO try Queen Anne 444.7000 plus offset tone 103.5 

As we approach the CR-16 we will continue to review these important critical tasks:

  1. Demonstrate the ability to send periodic situation reports from the local Emergency Operations Center to the next higher jurisdictional level utilizing multiple methods including HF, VHF, and/or UHF radio systems including amateur radio.
  2. Demonstrate the ability to relay information on damaged or destroyed communications infrastructure to EOC officials, and, neighboring EOCs, and state and federal level EOCs where applicable.
  3. Utilize ARES/RACES or other alternative communication systems to transmit emergency public information to an alternate location for dissemination to the media.

This exercise is in three parts:

  1. Continuation of the Winlink/RMS Express Exercise/contest
    Each EOC team will send emails via as many different gateways as possible and receive points for each. Each operator from the EOC team may send email on behalf of the EOC. These team members may be inside or outside the EOC but should be in communication with the EOC. Each team member must send their own messages.
  2. HF Voice Communications (for designated Seattle EOC stations)
    For this 5th Saturday drill EOC stations will check into the regional net using the 40M WSEN frequency and a series of relays if propagation on this band is poor.
  3. Local Options
    Locally, situation reports from the community will be taken via designated voice and fldigi frequencies, and all members are encouraged to call in with simulated emergency reports.

Participation Information

The Emergency Operations Center will be under construction during this event so we will not be operating from downtown this time. Our primary EOC will be NorthComm and they will be operating as W7ACS.

If you are available to staff the North Seattle College radio room, please contact Dave, KG7LEA at This station will be running voice, email and digital stations.

George, AE7G, will be heading the email effort again. For questions or to participate FROM YOUR HOME in the WinLink/RMS portion please contact George at

We are also looking for sector teams (or individuals from your home) to take voice and/or fldigi check-ins and traffic via REPEATER AND SIMPLEX frequencies. If the repeaters are down we need to be able to transmit traffic across the interesting terrain of our city. We would like at least one station in each of the north, central and south parts of the city that can practice relays and take good notes on simplex propagation from stations checking in. If you would like to participate this way, contact Jessica, W7EMF at

An ICS-205 will be sent out in the week before the exercise, and all members are encouraged to tune into those frequencies and check-in as instructed.

We hope to hear you on the air on January 30th!
