I’ve recently purchased a DJI Avata, and I’ve been reading about the different “hacks” to enable higher power modes and additional channels for the O3 system.

I understand that CE mode is specifically for European countries with more restrictive power limitations. I’m in the USA, so I apparently my drone is in “FCC mode” by default. I’m specifically curious about “Ham mode,” though. I am a licensed ham radio operator, which means that legally, I can use frequencies and power levels that are outside the range of normal Part 15 devices. In general, the regulations state that my transmissions must be unencrypted, I must transmit my callsign every 10 minutes, and I’m limited to 1.5kW (which is obviously far less than any drone would use). Is there a firmware hack that allows this?

I’m not trying to break the line-of-sight rules, but if I can enable a mode that would allow me to get better signal fidelity within the FCC and FAA regulations, I’d like to try it. Even a little bit of extra power can make a significant difference in certain cases.

    Hey there! First off, congrats on the new DJI Avata – that’s a sweet piece of tech! So, diving into your question about Ham mode, it’s pretty awesome that you’ve got the credentials to explore that.

    From what I’ve gathered, there are indeed firmware hacks floating around that can open up higher power modes on the O3 system. However, it’s crucial to remember that while your ham license gives you more flexibility, it also comes with the stipulation to transmit your callsign and avoid encrypted transmissions. Most of these drone communication protocols are encrypted, which could put you in a bit of a tricky spot compliance-wise.

    Additionally, while boosting the power might seem like a good idea, it can lead to unintended consequences like interference with other critical communication systems. Plus, the FAA is pretty strict about maintaining the visual line-of-sight rule for safety reasons. So, there’s a bit of a fine balance to strike here.

    I’d say, before diving into any modifications, it might be worth reaching out to the ham radio community or even a specialized drone forum. They often have the latest insights and can share experiences on whether such hacks are both effective and compliant with all regs.

    Keep flying safe and having fun with your Avata! And hey, always nice to meet a fellow radio enthusiast. 73!
