The Amateur Radio License "ELMER" Thread

#21
Sorry, yes I'm in the US. So would this http://https://www.sparkfun.com/products/155 be something to look into if I wanted to start thinking about DIYing a controller? I'm going to be ordering a realativly cheap 4 or 6 channel transmitter to learn to fly with, but I want to stretch my skills a bit. I am hoping to use RC planes and quads to do surveys for my ecological engineering degree, so rather than paying an extra $50 for every new button or function it make sense to use something like a raspberry pi and or an arduino. I'd like to make it modular so I can try out different radios, switch layouts, and the like.

You make a good point about wanting to keep the power as low as need to get the job done. So far all of my licensed transmissions have been under 5w. I am a little worried about losing signal with a very directional antenna. Would I need to build some kind of tracking mount to keep it lined up?

IFlyRCstuff I used a smartphone app and just bashed through the test until I had the rules down. The electronics questions are pretty basic. You'll be able to pass it.
I picked up a used FrSky Taranis X9D Plus 2.4GHz ACCST Radio & X8R Combo w/ case (Mode 2) with a damaged screen cover at a good price. The Taranis is expandable and programmable, you can switch the transmit module or add a second cost effectively. My goal is a animal tracking/counting survey system using a Nvidia core for non-domestic animals and a WiFi tagged system for domestic animals. I'd rather spend my time working the tag and vision issues, other people have create very flexible RC controllers. OrangeRX has a nice $60 433mhz 1 watt system that is plug and play with the Taranis.
FYI there is software for the PIXHAWK to act as a base tracking device... In case you wanted to save some money.

OK we all, if we can read, study sample questions and pass all three classes of licenses (I did) BUT would it not be better to slow down and actually understand the theory behind radio?I have a very good knowledge of electronics (even taught vocational school electronics for a bunch of years.)

I'm currently studying and taking a class for my Technician license. A buddy of mine got me into it and I've found that I really love it. With any luck, I may be getting my General on the same day as my Technician.

Eh, just get through the tests/licenses since you can usually do multiple tests in one sitting so you can save a bit of money and time, then take the time as you explore the hobby to really understand it!
