5.8GHz FPV Channels for Group Flying Without Interference

Picking the right channels matters more than turning up the power. Here is a US channel plan for solo, indoor, group and mixed analog/digital sessions, with the licensing rules that apply to each.

Two pilots can share 5.8GHz without much effort. Once you add a third and a fourth, or a DJI pilot joins the analog crowd, goggles start showing static lines, color flashes and sometimes another pilot's OSD. More transmitter power rarely fixes this. What fixes it is choosing channels that stay clear of each other and knowing which of them you are allowed to use in the US.

This plan is based on Oscar Liang's FPV channel guide, which he first wrote in 2015 and updated again this month, and on the FCC rules that cover American pilots.

Why channels collide

A video transmitter uses a band of spectrum, not one exact frequency. Analog needs about 30MHz. DJI and Avatar need about 20MHz in 25Mbps mode and about 40MHz in 50Mbps mode. HDZero needs about 27MHz. The wider the signal, the more space it needs from the channels next to it.

Raceband's eight channels are 37MHz apart, from R1 at 5658MHz up to R8 at 5917MHz. That is a little more than the roughly 30MHz an analog signal occupies. It still doesn't mean eight pilots can use all eight channels at once, because of intermodulation.

Intermodulation in one formula

When two transmitters are active at the same time, their signals can mix and create new frequencies that neither pilot is sending on. These intermodulation (IMD) products land at 2 × f1 − f2: double one pilot's frequency, then subtract the other's.

For example, take two pilots on 5760 and 5800MHz. Twice 5760 minus 5800 is 5720MHz. Twice 5800 minus 5760 is 5840MHz, which is channel F6. A third pilot on F6 now gets interference even though nobody is transmitting on F6. So you have to check every pair of pilots, not just the channels next to each other.

The US channel plan

Treat these sets as good starting points, not a standard. They come from a single expert source, Oscar Liang's guide. Race organizers such as MultiGP may publish their own frequency plans, and at an organized event you should follow theirs.

For six pilots, be careful with sets you find online. A commonly shared six-pilot option includes E4 at 5645MHz and E8 at 5945MHz. Both frequencies are outside the US amateur band, so don't use that set here, even if you have a license.

Two quirks worth knowing

First, some VTXs put out a bit more power on lower channels, so a pilot on R1 may have a stronger signal than a pilot on R8 at the same power setting. If one pilot keeps getting overpowered, the channel may be part of the reason.

Second, R7 and R8 avoid most Wi-Fi, but the 5850 to 5925MHz range is also used by vehicle ITS/C-V2X systems and UNII-4 Wi-Fi. Amateur users are secondary on these frequencies, so R7 and R8 aren't automatically clear.

Mixed analog and digital sessions

Digital systems are the hardest to fit into an analog group because their signals can be wider than an analog channel. Four adjustments help:

• Use 25Mbps mode. It takes about 20MHz instead of about 40MHz, which leaves room for everyone else.
• Keep your distance. DJI and Walksnail pilots should stand about 3 to 5 m (roughly 10 to 16 feet) from other pilots.
• Keep power low. 200mW or below works well for most mixed groups. Indoors, 25mW is usually the better choice.
• Analog pilots should skip R6 when digital pilots are flying.

The guide gives FCC channels for DJI/Avatar in 25Mbps mode that sit within a few MHz of Raceband. HDZero's FCC channels match Raceband exactly:

Those DJI/Avatar figures apply to 25Mbps mode only. In 50Mbps mode the same systems occupy about 40MHz, which is more than the 37MHz between Raceband channels.

Digital frequencies also depend on firmware version, region mode and power mode on DJI O3 and O4, Walksnail and HDZero. Use this table as a reference only, and confirm what your unit actually transmits in the manufacturer's current documentation before you plan a session around it. Some of these channels also raise a licensing question, covered below.

VTX power etiquette at the pits

The pits are where several quads get powered up close together while someone else is already in the air. These habits carry the channel plan over to the pit table:

1. Assign channels before anyone plugs in a battery. Write the plan down so each pilot knows their channel.
2. Only power up on your assigned channel. If you plug in a quad that is still on an old channel while someone is in the air, you can knock out their video.
3. Use the same power limit for everyone. 200mW or less in a mixed group and 25mW indoors. If one pilot runs much more power than the others, their signal and its mixing products affect everyone.
4. Give digital pilots room. Keep the 3 to 5 m spacing in the pits as well as on the flight line.

If you are still choosing a video system, the Video Transmitter (VTX), Analog video and Digital video chapters of FPV Drone Essentials cover the hardware side. For how the VTX fits with the rest of the quad, see FPV Drone Components Explained.

Which channels and power levels need a license

Many pilots get this wrong. In the US, an analog VTX needs at least a Technician class amateur license at any power level, not only at high power. Older advice said only high-power VTXs needed a license, but the numbers don't support that.

Why 25mW is not license-free

Part 15.249 lets unlicensed low-power transmitters use 5725 to 5875MHz, with a field strength limit of 50 mV/m. That works out to less than 1 mW EIRP. In practice every analog VTX puts out more than that, so even a 25mW setting needs a license. Analog video therefore falls under Part 97, the amateur rules.

What Part 97 allows

• Band: In ITU Region 2, which includes the US, 5650 to 5925MHz is open to Technician, General, Advanced and Amateur Extra licensees.
• Secondary status: Amateur use of this band is secondary. You must not interfere with primary services, and in the FCC's words you must accept interference from them.
• Identification: You must transmit your call sign when you finish transmitting and at least every 10 minutes while you are on the air. For analog FPV, the usual way is to put your call sign in the OSD.
• No commercial work: You can't use amateur radio for paid or commercial jobs.
• Power: Part 97.215(c) limits amateur remote control of model craft to 1 W. That rule is about control links, and the general amateur power limits are much higher, so whether it applies to video is debatable. Treat 1 W as a conservative upper limit, not settled law.

The edge channels

R1 is at 5658MHz and R8 at 5917MHz. With an analog signal about 30MHz wide, both extend slightly past the 5650 and 5925MHz band edges. No published FCC ruling has addressed whether that is compliant. If you want no doubt at all, pick channels further inside the band. Channels fully outside the band, such as E4 and E8, are not allowed.

Certified digital systems

Certified digital systems work under different rules. Part 15.247 allows digitally modulated transmitters up to 1 W conducted power in 5725 to 5850MHz, with antennas of no more than 6 dBi gain. That is why certified systems such as DJI O4 can be flown without a ham license, as DroneXL has reported.

Note how narrow that range is. Of the DJI/Avatar 25Mbps channels in the table above, 5660, 5695, 5878 and 5914MHz sit outside 5725 to 5850MHz. Don't assume the license-free Part 15.247 basis covers every channel your goggles offer. Because the available frequencies change with firmware, region mode and power mode, check the manufacturer's current documentation to see which channels your unit uses in FCC mode. If you modify or add hardware to a digital system, check whether it is still operating as certified.

A quick pre-session checklist

• Count the pilots and choose the matching set from the table.
• Put digital pilots in 25Mbps mode, and take R6 out of the analog plan if DJI or Walksnail pilots are flying.
• Unlicensed digital pilots should confirm their channel falls inside 5725 to 5850MHz.
• Agree on a power limit: 200mW or less outdoors in a mixed group, 25mW indoors.
• Check that every analog pilot has a call sign in the OSD.
• Don't use channel sets that include frequencies outside 5650 to 5925MHz.
