[17:44] good, good. [17:44] jonsowman, seems all of the radiometrix rx units feature a "data slicer"; will you be using it? [17:44] to do your RX? [17:45] we havent yet experimented with the best way of getting data to the balloon [17:45] the data slicer is one way of doing it [17:46] Matt_soton is the person to talk to about this [17:46] hmm; AF output is also provided.... seems like a job for a CRO [17:46] ping Matt_soton [17:47] sure i wrote this down somewhere, 2 secs [17:47] Physics has some masssive great CROs and I believe CCF signals have one. When Alex manages to blag one off radiometrix for whatever price I'll hook it up and have a look [17:48] DanielRichman: we're using OOK to talk to the balloon [17:48] have a look at this [17:48] http://balloon.hexoc.com/media/apextech.pdf [17:48] jonsowman, I was thinking that rtty might be easier [17:48] page 5, titled "in modem" [17:48] OK, thank you [17:49] DanielRichman: the problem with RTTY is that it requires tones [17:49] you'd need to demodulate those tones on the balloon [17:49] certainly doable, maybe with PLL tone decoders [17:49] or that data slicer :P [17:49] or a massive ADC [17:50] I'll use something [17:51] have you read the radiometrix appnotes? [17:52] skim read, yes [17:52] very useful [17:53] the data slicer can lose sync with the incoming signal for low baud rates [17:53] especially if you transmit a long string of 1s or 0s [17:53] is the signal isn't changing, so it can lose track [17:54] so if you go for low-baud FSK or something, some kind of bit-balancing is probably wise [17:55] hmm; perhaps a better idea to use an ADC and write something a bit smarter on the atmega [17:55] something like a biphase or bipolar encoder was something we considered very carefully [17:55] anyway dinnertime, be back in a bit [17:55] you might find other bits in that tech guide helpful :) [17:56] yes, it's surprisingly comprehensive, did you have to produce a report on your project for someone?

[20:08] Jasperw (~jasperw@92.40.141.12.sub.mbb.three.co.uk) joined #highaltitude. [20:10] as far as 434.075 & the other bands that we can use whilst airborne... these are "license exempt", no, but feature in the amateur bandplans: so is the deal that we can either choose to transmit using HAM eqipment, not having to specify our callsign etc but within the license exempt powers - OR - we can transmit with ham equipment at greater power if we specify our callsign and obey other rules? or are specially certified modules [20:10] only allowed to TX in those bands without a callsign etc? [20:11] DanielRichman, but the band plan applies to groundbased radio operation [20:12] jcoxon, so if I'm on the ground, say, and have a NTX2 and an 817 to hand [20:12] would someone without an amateur license be allowed to use the 817 to transmit 10mW on 434.075? [20:13] my understanding is that it needs to be a certified licence exempt module [20:13] i doubt yaesu have bothered to get that licence for their radio [20:13] Fair enough. [20:14] hence why teh ccc120x0dwdw setup is debatably legal [20:14] GW8RAK (~chatzilla@client-86-29-53-235.glfd.adsl.virginmedia.com) joined #highaltitude. [20:14] chembrow (~chatzilla@188-221-15-153.zone12.bethere.co.uk) joined #highaltitude. [20:14] i couldn't remember the exact name of the chipset [20:14] so the NTX2 can transmit whatever it likes on that band; any HAM can transmit up to their power limit aslong as they specify their callsign and that they're talking to a remote they own [20:14] I didn't follow/see that discussion [20:15] It's a more powerful unit, right? [20:15] a nice all in one... what's illegal about it? [20:15] well its just a chipeset [20:15] rather than a radio module [20:15] is it license-exempt certified? why is its legality fuzzy rather than defined [20:16] well this is where the whole thing is fuzzy [20:16] so radiometrix have got the NTX2 'module' certified [20:17] but the ccc12xcww chipset is just a chip - it doesn't have the extra bits included [20:17] so the whole thing from power regulator to antenna output is certified [20:17] sort of [20:17] what do you need to add to the ccc to make it work? [20:17] but of course we add on what ever antenna we want [20:17] so in some ways even the ntx2 isn't certified [20:17] You need to add more to the ccc than just the antenna? [20:18] i think so [20:18] i haven't researched it completely [20:18] well the NTX2 has features that keep your power down and it clips you to make absolutely sure you're inside the band you ought to be [20:18] so maybe just adding the antenna is OK [20:19] i think thats the current thought [20:19] they've done as much as they can [20:19] exactly, and to be fair, unless you want to sell a black impenetrable box with powersupply and everything included... there has to be a line drawn somewhere [20:20] yeah [20:21] http://focus.ti.com/docs/prod/folders/print/cc1111f32.html [20:23] has anyone asked ofcom? [20:23] where's the best place to source an NTX2 from? [20:23] radiometrix will sell direct for ~13 pounds [20:23] just call them up [20:24] or farnell but they sell for much more [20:24] thanks jcoxon. wasn't sure if there was a better source than them directly. I know some suppliers are less than happy about selling single units [20:26] yeah its odd calling them up for just 1 [20:27] though do say its for HAB [20:27] as if they see us as a potential 'big' market perhaps they'll make another freq for us :-) [20:27] Action: jcoxon wants another freq ntx2 such as 434.100 or something [20:30] cuone (~cuone@92.40.63.149.sub.mbb.three.co.uk) joined #highaltitude.
