LPFM -- Audience coverage map and demographics $99
Our Longley-Rice maps are underwriter friendly and suitable for publication in outreach materials.
LPFM -- Zoning exhibits: $150+
Formal letters concerning RF Safety, aka NIER, or other matters of electrical or radio-frequency concern, for inclusion in zoning applications or other interactions with zoning boards.
LPFM Interference from Translator

LPFM On-site build, repair, upgrade: $400/day
Plus travel, lodging, food, parts, up-front design/consulting at $50/hr. Spare bedrooms and home-cooked meals can save you money. We do everything from the microphones to antennas.

License-to-cover filings are free when we are part of the on-site construction.

LPFM Virtual Prometheus Engineer: As low as(*) $50 up front + $25/mo
Many LPFM stations don't have the talent or funds to have a regular on-site or consulting engineer. We can monitor many aspects of your station by installing a simple crypto-protected VPN so we can talk to your gear over the network. Once we know your station, you can call us with problems or questions, ideas about upgrades or changes to your coverage. It also means we'll have passwords and access methods for your various equipment, in case you lose them or need help.

Quick changes, like setting up e-mail alarms for an overheating transmitter or something, are included, and anything "big" we can do for our normal hourly rate of $50, which is a lot less than most broadcast engineers charge, and there's no travel fee!

For another $15/mo, we'll more-closely monitor your EAS and do your ETRS on-line filings for the national tests!

(*) Many stations are simple, but some are not. Our time for research, design, aquisition, construction, provisioning, installation and learning your setup can increase the initial cost. Similarly, if you have several different networks, a 3-hop STL, an old transmitter hooked to RS-232 monitoring, and want us to keep track of your automation, or monitor your modulation or RDS, that will increase the monthly price.

Build your Station

Our expert engineering services and low-cost solutions are great for community-based FM stations -- especially low-power FMs. Unlike the "turn-key" solutions offered by some engineering firms, we like to work collaboratively with stations throughout the construction process and to provide technical education for station volunteers in conjunction with our technical service.

Our process starts with design consulting to figure out what you want and need, and what people and resources you already have. That leads to a sample equipment list with prices plus a cost estimate to hire us. From there you can purchase equipment through us if you like, and have us come put it all together with you.


Whether your station has been on the air for years, you’ve just received your construction permit or your application is still being processed by the FCC, we can do the engineering work for site moves, channel changes, and more.

Do you need to move your transmission site but aren’t sure where to begin looking? Do you have the best possible transmission site to reach the maximum number of people in your target audience? Are you receiving unwanted interference? Is a big, bad commercial station breathing down your neck? Is zoning asking you questions? Do you need to respond to an FCC petition, or file one? Maybe you just need to update some information on file like your address?

From addresses and antennas to FCC filing and followup, we can help.

Consult and Educate

We answer questions and provide education on a wide range of issues facing non-commercial radio stations, and when we don't know the answers, we can refer you to someone who does.

Application Tracking

Prometheus Torchlight constantly tracks changes to your FCC data and emails you alerts about important changes. Petition filed against you? You'll know right away. Learn more and subscribe today!

Coverage Demographics and Maps

Another station punching a hole in your coverage? Are potential foundations and underwriters asking to see your coverage? Wondering how many people could listen, and a little about who they are? If you raised or moved your antenna, or changed frequencies, would you increase your coverage?

Our Longley-Rice plus interference maps and population numbers are easy to understand. Learn more!

Supporting Stations: What We Look For

Prometheus works towards a media system that allows everyone to have a voice on the airwaves. With limited resources, however, we use the following questions to prioritize which station applicants get our closest support.
  • A Purpose. Do you have a clear mission that we can get behind?

    We prioritize groups whose mission, vision, and values align with our own. We build participatory radio as a tool for social justice organizing and community expression, and we help grassroots organizations to build communications infrastructure to strengthen their communities and movements.

  • Community. Do you have strong local participation and engagement?

    Local roots in your area and past history of working in the community? Relationships with other organizations and communities in your area? Demonstrated ability to collaborate and work across differences Volunteer involvement or a plan to engage volunteers?

  • Diversity. Will your station bring new voices to the airwaves?

    Leadership from communities underrepresented in the media and those historically disenfranchised from media ownership and access? A plan to build the leadership of people from these communities in your station’s governance and programming?
