Happy 150! The Hiram Percy Maxim Birthday Celebration!

The Hiram Percy Maxim 150th Birthday Celebration was held from August 31, 2019 through September 8th, 2019.  Maxim, the League's first president and cofounder, was born on September 2, 1869.

Objective: This operating event is open to all amateurs, and the goal is straightforward:  Find stations operating in the event, many adding “/150” to their call signs, and contact as many as possible during the 9-day celebration on each of the event bands (using any/all of the 3 event modes on each band).

Time Period: The 9-day event begins 0000 UTC August 31 and runs until 2359 UTC September 8, 2019.

Eligibility: All amateur stations may participate.

Who is eligible to use their “callsign/150”?   W1AW and ALL ARRL members are eligible and will append /150 to their call sign during this event (this includes DX Stations who are ARRL members, who may operate as callsign/150 if permitted by the regulations of their country of license).

Exchange: All W/VE stations send RST and their ARRL/RAC Section; DX stations send RST and “DX”.

Bands: All Amateur Bands LF/HF/VHF/UHF/SHF/Microwave/Light (excluding 60, 30, 17 and 12 meters).

Modes: Three (3) mode groups will be recognized in the event:
       Phone (any/all voice modes count as “Phone”)
       Digital (any/all digital modes count as “Digital”)

Scoring:  Cabrillo log (or ADI) files must be supplied. ARRL will calculate all final scores based on the participant uploads to our event web app at

Multipliers: 84 in total – contact just once each of (83) ARRL and RAC Sections (RAC sections include the Canadian “NT” Northern Territories - encompassing VE8 / VY1 / VY0) - and DX (1).   See for ARRL/RAC Sections.

QSO Points:

       3 points per QSO: Contacts with W1AW/150 will earn 3 points per QSO;
       2 points per QSO: Contacts with any ARRL member will earn 2 points per QSO - these stations will also identify as callsign/150:
       1 point per QSO:  Contacts with non-members (ie, those not mentioned above) will earn 1 point each, and will identify with callsign only (no additional / number will be used).

       150 Bonus Points will be earned by successfully completing one or more activities as described below – these are determined by your responses when uploading your Cabrillo log (or ADI file) to our web app:

LoTW Certificate

  • How to create an HPM150 LoTW certificate

    ***  If you have not done so, please download the latest version (2.4.7) of the TQSL software which is available at:

    • Open TQSL and click on “Callsign Certificate” on the top menu (top line).
    • Click on “Request New Callsign Certificate”.
    • Enter your primary callsign/150 (i.e. N1SFE/150) and your DXCC entity.  Choose QSO Begin Date of August 31, 2019 and QSO End Date of September 8, 2019.
    • Choose the following option:   My former personal callsign or a portable modifier for my current callsign. If you used a password for your primary callsign, use the same password for the /150 callsign.   (If no password was used for primary callsign, leave the box blank and click OK or FINISH.)
    • Near the end of the request process a box will come up with a list of your callsigns.  Highlight your primary callsign and click FINISH.
    • When asked “Do you want to upload this certificate request to LoTW now?”, click the “Yes” button.  DO NOT delete the newly-created red circle request in the TQSL program. No postcard will be issued for USA participants.  No additional documentation is necessary for DX participants.

    Once we process the certificate, you should receive an email from LoTW with the corresponding TQ6 file attached.  Use the TQ6 to activate  your new callsign/150 certificate. (red circle changes to gold ribbon). You can either double-click on the TQ6 file or save it and click on the “Load Callsign Certificate” ICON in the TQSL program under the “Callsign Certificates” TAB.


    When you have your new gold ribbon callsign/150 certificate, please make sure to create a separate and uniquely named Station Location under the “Station Locations” TAB.


    ** Be careful when signing QSOs to choose the proper Station Location for the /150 callsign. **
