How many others do you know use 70cm at a launch? Is it usually that crowded where you fly? As far as I know, the range of frequency programming options spans the width of the band.
I was mainly using that for testing the devices for other uses.Vance, to what device are you sending the data (over bluetooth) and what program/s are you using?
I looked at that unit and as long as you use a good power regulator it should be fine.This GPS might be a possibilty to use with this hardware: https://www.sparkfun.com/products/13740 I have a couple and will look into it. AKS

According to the data sheet the maximum input voltage is 3.6v.
A lot of the other raw chips or modules can handle 3-5v which means they can run direct from a 1s lipo.
Just purchased a batch of this stuff to experiment with, including the 500mW version (I have the advanced radio ticket, VK3TRK ).
I think this might go into the NC of the Nike Apache when I get around to the two-stage flight.
Nice call sign! Vanity?
Got my 433 radios today. Unfortunately it came with 2 SMA male antennas but the AIR module is also an SMA male. For those who have these does yours have different SMA genders on your modules?
Change the com port speed until you see some strings decoded properly. I don't know what the default mode is for the GPS chipset you're using. Try 9600. I haven't received mine yet so I'm not speaking from of position of authority.OK, and please bear with me here. This is screen shot from U-Center. I have communication over the radio on COM7. The status is flashing green on the bottom COM7 at 57600 baud after I figured out the reversed TX-RX deal. However, the packet console indicates errors, and no GPS data is being deciphered. Is this related to the airspeed setting on the radio?

My experience in the past is usually a comport mismatch or serial protocol issue. Kurt
My 3DR radios came in yesterday. I dissected one of the little 6 connector wires, and wired in a 1S 500mAH LiPo cell to the V and G terminals of the air module. I used a little Molex 2.0 type connector which the LiPo has on the end. Wanted to keep it so I could still plug it into my little Syma quadcopter.
Downloaded Mission Planner, and stumbled through it. This is all quite new to me, so I am wandering through the fog. However, a future project involves building a custom quad-copter so I needed to learn this stuff anyway. I also took delivery of a nifty little Arduino Uno experimenters kit yesterday, so that sits ready for my tinkering pursuits at some future point.
I first tried to load Mission Planner on a laptop that still runs XP, but had no luck there. I use that laptop for running field programs, like my OBD2 automotive diagnostic programs. I installed net framework 4.0 on it, per the Mission Planner install instructions, rebooted....and it still says I do not have net framework 4.0. Oh well. I was hoping to use that laptop to receive the GPS data at the launch site. Next I'll attempt putting that on my Windows 10 laptop, that I would rather have stay away from field operations.
Anyway, GPS still has not arrived, but I wanted to make sure the radios were operational first. I ended up installing Mission Planner on a Windows 7 desktop, and got it to run after another net framework update. I got this screen from Mission Planner after loading the settings, so I am guessing this means all is copacetic.

I hooked up +V and Ground to the LiPo battery (1s 500mAh) to the air module, and that was all.
