Who Can Be A W5M Special Event Station Approved Operator?

If you wish to be one of the official W5M authorized operators for the OKC Memorial Marathon 2025 SES, contact Mark Kleine N5HZR, at mkleine@live.com. When approved, you may, subject to the coordinator’s approval, select any available two-hour operating time slot for the band and mode (SSB, CW, Digital) of your choice, except operation on 12 Meters, 17 Meters, 30 Meters, 60 Meters, 630 Meters, and 2190 Meters is prohibited.

Approved operators must use an approved electronic logging program capable of creating an ADIF file. Email your completed logs to by May 11th, 2025.

All approved W5M operators are expected to observe all FCC regulations, including only operating on frequencies allocated to their license class and at permitted power levels. Violators, may The Old Man be merciful, will be Wouff Honged!

Portable W5M Operation

As a part of the OKC Memorial Marathon, the special event callsign W5M will operate from Oklahoma. This event starts 2025-04-19, at 0000z and will run through 2025-04-27, at 2359z, using the callsign W5M.

Portable W5M Rules

• Each operator must follow the rules for their own license class. Stay in the sub-bands that you are legally allowed to operate.
• Operators can operate anywhere in the United States.
• Each band/mode combination can be activated simultaneously. For example, N5OP could be working on 20 M SSB, N5OK could be working on 20 M CW, N5AZQ could be working on 20 M FT8, and N5HZR could be on 40 M SSB, all at the same time.
• Operations start at 0000z April 19, 2025 and stop at 2359z April 27, 2025.
• Operations are not allowed on the 12 M, 17 M, 30 M, 60 M, 630 M, or 2190 M bands.
• All logs for the week must be consolidated into one ADIF file. Email your completed logs to by May 5, 2025.

When you sign up for a two-hour slot start time, you are also selecting a band and a mode. Signing up for CW on 20m is one slot, phone and digital modes are two other slots.

Taking a slot on 40m CW does not mean you may use any mode on 40m. You may only use the band and mode you have been allocated, for the time period you requested. You may request multiple slots throughout the week.

Do you want to run another two-hour slot? Request that slot here before you start operating. Once you have been approved to operate by the coordinator, you are ready to go.

We only allow one operator per band and mode at a time. Two operators can not share a slot. ie. W5M running CW on 7.022 and another station running W5M CW on 7.042 would be a violation of our agreement.

If you have any questions, please contact OKC Memorial Marathon 2025 SES State Coordinator Mark Kleine N5HZR at mkleine@live.com.
