[14:35] nope [14:35] its not correct, thats for sure [14:35] but its such a short distance it doesnt matter [14:36] true [14:36] its less than 1/8th wavelength, so it doesn't really matter [14:36] i came out on a width of 2.1mm [14:36] that soudns right [14:36] that trace you see there isnt 2.1mm [14:36] its just whatever i could fit [14:37] Darkside: During the K6RPT flight, you mentioned there were two ways to do AFSK with the ADF7012. I'm curious what those are. [14:37] going to send it over to seeedstudio now :) [14:37] thanks Darkside [14:37] np [14:37] Zuph: one is using the ADF7012 to generatr carrier and modulating the crystal [14:38] using a varicap diode [14:38] the other is sending 10101010 continuously in FSK mode and playing around with the data rate [14:38] so its basically sending a AFSK square wave [14:38] which is pretty dirty [14:39] Yeah, version two is the one I was going to try. I think that's what the Big Red Bee tracker does. [14:39] yeah its dodgy though [14:39] i'd do the first one [14:39] much cleaner [14:39] http://www.silcom.com/~pelican2/PicoDopp/MB_SCH.jpg [14:40] theres even a reference design there [14:40] Hey, neat [14:43] I'll probably fiddle around with the square wave, since the circuit I just built could do that without modification.

[21:35] (contd) like this http://www.findmespot.com/ (noit that specifically, but that kinda thing - do you reccomend any specific devices [21:36] to send a stream of updates to a grounded device - sms to phone, message to server etc? [21:37] really? i have an arduino, but the recievers cost <£150 at least right? [21:37] plus soldering and coding! [21:39] you might find that if you launch at cambridge, there'll be people willing to help out on lending an rx unit or receiving for you out of pleasure [21:39] hi_im_tom: Don't forget that all of us in UKHAS help to track the radio payloads, so even if you don't have a radio to track it is likely other people will - [21:39] My receiver was less than £100. And you could put it back on ebay after the project. [21:39] and soldering's easy [21:39] and that coding's already been done ;) [21:41] wow, that'd be amazing - i've joined the ukhas mailing list, so if i sent an email asking for tracking help on the day would that be okay (even if my friend and i didn't have a reciever) [21:41] Yes, you'll get several people helping, sometimes 10 or more [21:42] and about the coding - i've seen some of it in upu's guide, but iirc it's not complete - is there anywhere i can find could that i could import straight into the arduino program and go (i know that's asking a bit much, but you never know :) ) [21:43] @dave - that's excellent, thanks (in advance haha, i don't plan to launch for a few months ! ) [21:44] hi_im_tom: The code does all depend on the components that you decide to use - are you up to sorting your own circuit and gps tc. out?
