Special thanks to Marty KB3MXM for receiving and replying to submissions and compiling the database. He continues to verify validation, and analysis will continue in the coming weeks, and hopes to publish a comprehensive usability dataset to support ARES ECs, RACES, AuxComm, ACS, and EmComm (ESF-20).
Additional benefits include creation of popular code plugs. This will result in a measurable picture of repeater usability across MDC jurisdictions. This also gives the MDC Affiliated Coordinator (ACC) and amateur radio clubs an opportunity to promote on-air meetings and nets.

ARRL Maryland-DC Section-Wide 2026 Simulated Emergency Test (S.E.T.)
Complete Your FEMA ICS-205 Communications List
The ARRL Maryland-DC (MDC) Section is conducting a Section-Wide Simulated Emergency Test (S.E.T.) and is asking all participating amateur radio operators to complete a local FEMA ICS-205 Communications List.
Beginning Saturday, October 3, 2026, please spend the following seven days monitoring the VHF/UHF and 6-meter repeaters that are reachable from your QTH.
Use available online resources, such as The Repeater Book and other Internet repeater directories, to identify repeaters that you can reasonably access from your location.
What We Are Asking You To Do
- Identify the VHF, UHF, and 6-meter repeaters reachable from your QTH.
- Record the repeater information on a FEMA ICS-205 / Incident Radio Communications Plan.
- Include your:
- First Name
- Amateur Radio Callsign
- 6-character Maidenhead Grid Square
- Identify the document as 2026 S.E.T. ICS-205 in the email subject line.
- Save your completed file using the following format:
CALLSIGN-GRID SQUARE-2026SET.pdf
Example: KB3MXM-FM19OK-2026SET.pdf
Submission Deadline
Please complete and submit your ICS-205 no later than Sunday, October 18, 2026.
Completed forms should be emailed to mdc2026set@gmail.com
Marty will collect the completed ICS-205 forms and use the information to develop a Maryland-DC Section-wide Communications List. The resulting information will also provide a useful communications resource for Maryland county Emergency Coordinators (ECs) and ARES organizations.
FEMA ICS-205 Form
A blank, fillable FEMA ICS-205 form is available here:
A completed sample ICS-205 is also available for reference.
Questions or Assistance
If you have questions, need assistance completing the form, or would like clarification about the information to include, contact:
Marty Pittinger, KB3MXM
443-326-1783
Monday–Friday, 9:00 AM–3:00 PM EDT
Your participation will help build a more complete picture of amateur radio repeater coverage throughout the ARRL Maryland-DC Section and provide valuable information for future emergency communications planning.
Thank you for participating in the 2026 ARRL MDC Section-Wide S.E.T!
