Using a drone to help place an antenna at the 80' to 200' level of a sturdy Douglas Fir tree.
I invite and welcome your comments and suggestions regarding the application that is described in this discussion. I have been building and flying drones for about three years, and am early in the process of adding collision-avoidance to my Phantom 2 Vision, and then to a 3D Robotics X8+. Once I have collision-avoidance working on the Phantom, I would like to add a solenoid release mechanism behind the camera. The release mechanism would serve to securely carry fishing line to a suitable and…Read more…
I'm building a prototype rover using arduini, raspberry pis, L298N, etc communicating over I2C. Pi is gonna run direwolf tnc so I can drive the bot via terminal before I get fancy and go AX25. Would kinda like to treat it more like a NASA rover than RC car (will be upgrading from $10 crawler kit to using 2 hoverboard motors on welded frame) so I'm wondering what to do about video. Plenty of room on 70cm, and I have spare 70cm ht's to play with. Cross-band with 2m up and 70cm down with ATV and and return data? KISS for now and just j use 2m for data and 70cm for video?

You'll probably need to watch your layout and have a good LPF on the 2m up. The 3rd harmonic can and will desense the 70cm if using 70cm for any RX. Are you planning
2m as the flight control channel? I run 900MHz and 2400 for everything here...LoRa. Best luck with the project (I've 'been there' with 2m and 70cm...lol)
Fascinating! Is the general focus of this to be long-distance control of drones?
- Let me guess, there is a lot more to it than just that?
Recently, did an FPV presentation at my local HAM club in Temecula, CA.
Even my amateur knowledge in FPV (using 900mhz, 1.2Ghz, 433mhz) was of great interest to the older HAMs. Wonder which RF people are using here?
helloo...i just build my quadcopter on kk multicopter board v5.5. The construction part gone great, but when i started controlling it through RC, am not being able to provide equal rpm to all the rotors for throttle up and down.
So would u please suggest me some way, how to control throttle up and down initially...
A little help from u wud be appreciable...!!
@cory Congrats on the new ham lisc and you are doing the right thing getting the general ticket asap if you really want to enjoy ham radio the HF bands is where its at. If you want some help with anything ham drop me a note. And you are in the right spot for APM for sure.
Just joined the group, new to ham radio and drones. I'm simultaneously building my first APM based quad, and studying for my General ticket upgrade. Glad to see other hams here.
Check the box again, may find x4 along X8 in there , hi hi
My X8 has been in the box for over a year, I opened the box when it arrived, did a parts check and thought I'd get to it a week later, hi hi.
Same here , too many toys to complete/play and no free time ( away from xyl and morning QTH ) :(
