This is (in our opinion) the one aspect of the Local Community Radio Act that the FCC got the most wrong. Under the FCC's (misguided) interpretation of the LCRA, LPFM stations that have a third adjacent channel full power or translator station within 100 km must make announcements for that station unless the distance from the LPFM to the third adjacent channel station is less than the 73.807 required distance for that station class using the second adjacent channel chart. Only the closest station on each of the two third adjacent channels must be considered. For example, if you are on 95.5 and you have third adjacent channel stations on 94.9 that are 85 km (Class A) and 4 km (Class C3) away, you do not have to make an announcement for that channel however if you have stations on 96.1 that are 98 km (Class C) and 32 km away (Class A), then you will have to make an announcement for the station 32 km away.Tags: 73.807, 73.810, LCRA, Third-adjacent channel

- When can I move a station more than 5.6 km away?
- How far can I move an LPFM station?
- Can a translator carrying an LPFM station have a power higher than the LPFM station itself?
- I filed an amendment to my application but the power and HAAT still show 0 in both the FCC and REC systems. How do I fix that?
- Can I use a directional antenna to address a second adjacent waiver issue?
- My application status is showing "Accepted for Filing". What exactly does that mean?
- Two MX LPFM applicants are short spaced by about 20 km. Can we reduce our power or use directional antennas to be able to both operate at the same time?
- Two LPFM stations are spaced precisely 24 km apart, is interference between the stations still possible?
- Why was my station only authorized a very low power?
- Can I reduce my power to decrease the size of an overlap zone for a second adjacent channel waiver?
- My LPFM station in San Diego (Tucson, El Paso, Brownsville, Yuma) was only authorized 50 watts. Why?
- I heard that I may have to give announcements for the first year for third adjacent channel stations. What is this about?
- If there is a pending or granted LPFM applicant who no longer wants their channel, can have that applicant/permittee request a dismissal/cancellation as a part of a settlement agreement (in order to place another MX applicant on that channel)?
- Can the FCC grant a waiver of the Local Community Radio Act?
- How do I extend a construction permit (CP)?
- What does it mean (on fccdata.org or on the FCC website) when an application is "superseded"?
- Are full power stations running hybrid HD Radio (IBOC) afforded any additional protections above and beyond the current analog protections?
- How can I get a translator for an LPFM station?
- Can the FCC waive minimum distance spacing requirements for a full-power station on the same channel or first adjacent channel?
- I am already granted with a second adjacent waiver but now I need to make a change on Form 318 for the same channel. Since I have already received a second-adjacent channel waiver for a particular station, do I have to submit a new waiver request?
- If two stations are currently in a time share agreement and another (non-adjacent) channel becomes available that is properly spaced, can one of the two stations ask for a move to the other channel claiming that eliminating the time share will "reduce interference"?
