Grant Application Instructions
To apply for a grant, use the application form at https://grants.ardc.net. You can apply for a grant at any time during the year. Four times a year, we review applications. Our grantmaking budget varies yearly; in 2026 we aim to fund approximately $3.8 million. As of 2025, we fund about 30% of the submitted proposals.
If you feel that you have a program or project idea that fulfills the mission of ARDC, but is not mentioned here, we suggest contacting giving@ardc.net or calling +1-858-477-9900 before submitting your application to talk through your idea.
General instructions for all applications
- Review our grantmaking goals to make sure your project aligns with our work. In particular, please note that projects that are not open source and open access are not eligible.
- Make sure your organization is eligible for a grant. Eligible organizations include:
- US-based 501(c)(3) public charities, government agencies, schools, and universities
- International charities, nonprofits, schools, and universities
- Radio clubs and groups who are NOT nonprofits may be eligible if they work with a nonprofit fiscal sponsor. Fiscal sponsors must be 501(c)(3)’s, local government organizations, universities, or schools. ARDC usually cannot find a fiscal sponsor for you, so reaching out to other clubs in your region may be your best bet.
- Individuals are only eligible to apply if they work with a nonprofit fiscal sponsor.
- US-based and international for-profit businesses are currently not eligible for ARDC grants.
- Review our application questions. You may fill out these questions in our online application form or upload a PDF file. Skip any questions irrelevant to your work. We accept applications in the English language.
Important notes
- If your organization is a 501(c)(3) public charity, please consider whether or not your organization will meet the public support test after you receive an ARDC grant. We cannot offer legal advice on this matter, but we suggest that you consult with an attorney or CPA to ensure that you will meet this requirement. For more information on the public support test, go to Understanding the 501(c)(3) Public Support Test.
- Proposals may be sent to outside experts for peer review when there is not sufficient expertise on our review committee to assess a proposal.
- If you would like to get feedback on your project before putting together a full proposal, you can send an email summarizing your idea or schedule a time to talk with staff by contacting giving@ardc.net. This may help avoid spending time on a full application that would not be considered.
Filling out the application
Include letters of support from any organizations that you’ll be partnering with, such as schools, government agencies, or nonprofit organizations. You are encouraged to include letters of support from experts who endorse your project or groups in your community who will benefit from your project.
As you write your proposal, keep in mind that the review committee will use the following criteria to evaluate your application:
- ARDC Goals: How well does the project meet our vision, and at least one of our stated goals for Learning, Experimenting, and Doing? Does the project fulfill ARDC’s open access goal?
- Project Design: Does the project have a clear design plan? Does it have the people, expertise, time, and organizational structure to likely be successful in meeting its goals? Does the organization have a track record of success or of learning from failures? Is the work schedule reasonable?
Successful projects must have a clear design plan that outlines the steps you will take to accomplish your goals. The work schedule should be reasonable, and enough detail should be provided to show our reviewers that your team knows how to do the work and that your plan is viable. Lack of detail in the project plan is the most common reason applications are rejected. - Budget: Is the project’s budget and size appropriate for the outcomes? Does it have a reasonable chance of success with the stated equipment?
Your project’s budget should be appropriate for the results you want to achieve. For example, we don’t want projects to choose cheap equipment just to save money if that equipment is more likely to fail, but we don’t want to see unusually expensive equipment without explanation for why it is needed. Similarly, use volunteer labor when appropriate, and hire professionals if you don’t have adequate experience on your volunteer team. - Reach and impact. For each of our goals we want to get “more people” doing these activities. Does the project impact a large number of people? Or does it impact a smaller group but to a large degree? Does it create a model that can be replicated? Does the project make new contributions to their field?
When possible, estimate how many people you are hoping to reach if you are successful. Large dollar projects should reach many people and have a correspondingly big impact. Projects that have an in-depth impact on a smaller group of people are also acceptable, for example a multi-week class.
Impact should be measurable and specific. For research projects, impact may include how the work contributes to their field. Development projects are judged based on their adoptability, usability, and community contribution. - Sustainability. Are the project outcomes sustainable? When appropriate, will the impact of the work continue beyond the lifetime of the grant, and how so?
- Community support. Does the project have community support? This can be in the form of financial support, donated equipment, volunteering time, community feedback or something else. If a project involves a school, city, county, or state government, it is important that those applications include letters of support from those organizations.
- Geographic area. Projects in areas where few other grants have been made are preferred. Projects serving low income areas are preferred. International projects are preferred, especially those from developing nations.
- Service to under-represented communities. ARDC aims to introduce amateur radio or digital communications to new audiences. Projects that serve under-represented communities in amateur radio or technical fields are encouraged. Projects that introduce new audiences to amateur radio, such as those in makerspaces, are encouraged.
- That something special. Does the project offer something not captured above? Is it exceptional or exciting? In the spirit of innovation and flexibility, we may fund exceptional projects that don’t perfectly align with stated criteria or categories.
In general, please note that the larger the project, the more detailed information we may need in your application and subsequent reports.
If it’s your first time writing a grant, the video How to Write a Grant Proposal Step-by-Step may help.
- You can disregard the recommended page lengths and sections mentioned in this video under “What Goes in a Grant Proposal.” Instead, focus on answering the questions on our application. You can make your answers as long or as short as you need to fully explain your idea.
- You can also skip listening to the information in this video after the 21:45 mark.
If you choose to use AI when writing your proposal be sure to thoroughly edit for clarity, brevity, and accuracy. If the proposal is extremely long and hard to understand, we can’t evaluate or support it.
Creating your budget
Group small things together like “building supplies: screws, paint, tape, etc. – $200.” Avoid grouping major expenses like “New Ham Shack $30,000.” Separate out any costs for materials, labor, and any other fees that might be included, such as permitting.
You can submit your budget in any format, though spreadsheets are preferred. Your budget may include:
- Personnel. This includes salaries and benefits for individuals working on the project (unless everyone is a volunteer). Include an estimate of how much time you expect these individuals will work on this project.
- Supplies and equipment. List the supplies and equipment that you will need for the project. Don’t forget about shipping costs, taxes, and any fees. It’s okay to round up slightly to give yourself room for these costs. Be specific about any radio equipment or big-ticket items that you want to buy.
- Travel. Include any travel costs that are directly related to the project.
- Marketing. Include costs for marketing materials that are directly related to the project. For example, include the cost of printing flyers or purchasing social media ads to advertise a class.
- Other costs. List other costs that are directly related to your project, such as costs for building permits, if needed.
- Indirect costs/contingency. You may include up to 20% for indirect costs, such as phone, internet, rent, accountants, software, bank fees, human resources, lawyers, small supplies, contingency for unexpected project costs, and anything else that can be hard to itemize. You can use these funds for any additional overhead costs. If your organization’s indirect cost rate is more than 20%, we ask that you cost-share any indirect amount over 20% to allow us to maximize the funds we can distribute to others.
- Other funds that are available for this project. Tell us about funds from other donors who are supporting this project and any money already set aside for this project. It’s okay if ARDC is the only funder, but it can be a bonus to know if other funders or people in your community are willing to invest in your project, especially if it’s a big one. If you are approaching other funders to request donations but have not heard back yet, please note that as well.
Your budget should not include:
- Funds for lobbying. Advocacy work is okay, but trying to specifically influence elected officials to vote in a particular way is something we cannot legally fund. See the National Council of Nonprofits’ Advocacy vs. Lobbying for more details.
If it’s your first time creating a grant budget, Writing a Budget for a Grant Proposal has many good tips on what to include (and what not to include) in your budget.
Project-specific instructions
Amateur radio projects
- Regular use and maintenance. ARDC will support projects that radio amateurs will regularly use and maintain, such as repeaters.
- Spectrum Usage. Projects that get more people using additional and new bands, modes, & technologies are encouraged.
- Strong outreach plan. Our mission is to promote and support amateur radio. We prefer to fund projects that have an outreach component that introduces new people to the hobby or strengthens skills and connections within the hobby. For example, if you plan to fix a broken repeater, will you use it as an opportunity to educate others and engage your community as volunteers? Will you send out a newsletter announcement or let folks know in some other ways about the project? See our blog post on outreach if you need help.
- Use of modern technology. We recognize that in some cases older technology may be the most appropriate for a given project, but in general, we encourage grantees to use the most modern technology available.
- Permissions and Permits. You may need permissions or permits for structural changes to buildings or adding antennas. Before applying to ARDC, understand what is required by your building facilities and local government. Obtain any needed permissions or permits in advance if you can, and allocate time in your project plan to finalize any needed approvals. If required, budget for engineering reviews or professionally licensed contractors. In your proposal, tell us if you have already obtained approvals or if you have contacted your facilities and are aware of what is required.
Here is some guidance for some particular project types:
- GMRS. GMRS systems are generally not eligible for an ARDC grant, except as a tool to enhance amateur radio public services or to encourage amateur radio licensing and training. All GMRS equipment must be FCC Part 95 certified, including repeaters. Network connection (linking) of GMRS repeaters, or stations, for carrying traffic is not permitted (see the tab marked Operations).
- Repeaters must be open for use by all licensed operators and freely accessible
- Emergency communications vehicles. This is a type of application that we receive a large number of requests for. See our blog post about how to be successful with making your trailer grant proposal stand out.
Education projects
- Staff involvement. University and K-12 projects should have a teacher, professor, advisor, or other staff person involved, even if the project is primarily being carried out by students. This is to ensure that the program continues even after students graduate.
- General STEAM and robotics programs are not as closely aligned with ARDC strategic goals for funding, unless they have a strong amateur radio or digital communications/information technology component.
Please also review materials related to learning and education in our strategic approach and priority areas for funding pages.
Scholarships
- ARDC prefers to fund scholarships that have a tie to amateur radio and/or its intersection with communication/information technology. We prioritize scholarship programs that tightly align with our mission.
- ARDC does not prefer to support scholarships at individual universities or colleges.
- Organizations looking to apply in this category should apply during our September 1st funding window.
- Scholarship applications have different criteria for evaluation:
- Goals: Do these scholarships support students interested in amateur radio or a relevant STEM degree?
- Design: Is the application process for students reasonable and accessible? Does the organization have a track record of successfully awarding scholarships? Do these scholarships include additional support for student success? Do they track student outcomes?
- Budget: Preference for programs that award medium or large scholarships to students over many small dollar ones. Does this program meet our indirect cost policy? Are the costs for any additional supportive programming appropriate?
- Reach and impact: Are the scholarships open or are they restricted to a particular school?
- Geographic area: Do these scholarships reach a broad range of areas? Encouragement for international scholarships especially those from developing nations.
- Do these scholarships reach students with financial need? Do they reach students underrepresented in amateur radio / STEM fields?

Research and development (R&D) projects
- Have a clear roadmap. Development projects should have a clear end product with a defined scope of features and a plan for adoption by users. If your request is for a project that will take several years, it should still be clear in your proposal what the scope of the eventual end product is, and how the goals of the proposal connect back to that end product. Show us the roadmap for your project and where the activities in your proposal fit within that.
- Avoid unnecessary jargon. Introduce the goals of the project in a way that avoids jargon or undefined acronyms. At the same time, provide enough detail for peer experts in your field to be able to assess your work.
- Have a clear impact. Successful proposals will clearly communicate the intended benefit of the work in terms of intellectual contribution to the field, as well as broader impact of results.
- Share results. Results (including technology developed) and documentation must be openly available for others to learn from. Developed software and data sets should/must be open sourced. We prefer strong plans for sharing results with the public and other researchers.
- Assess risk. R&D proposals should include an assessment of risks to the project and summarize the steps you will take to mitigate the risk. We understand that some projects are higher risk, but may have much higher reward or educational benefits.
- Have a plan for future funding. ARDC is unable to fund your work indefinitely. Include in your proposal how you intend to fund ongoing costs for development projects.
- Advance the art. You should summarize in your proposal how your project will build upon existing work.
- Research-focused projects: A literature review or citations may be appropriate to demonstrate the current state of your field and identify open questions. Provide published examples that describe the tools you will be using and demonstrate their viability. Your proposal should include a clear hypothesis or objective.
- Development-focused projects: You should summarize in your proposal what similar work has been done and any projects that have been built already. Show how your project is building on those current solutions or existing products to solve a key problem.
ARDC funds digital communications projects that align with our vision, which aims to:
- Enable maker/hacker/developer communities to learn, experiment or do (deploy)
- Avoid gatekeeper technologies
- Have a broad impact (open and shareable, leverageable to other groups) versus serving a single group of individuals
- Not likely be funded by other sources
Note that projects we fund are not necessarily restricted to wireless technologies.
