[14:03] in reality, you will probably hardly be able to notice the losses from the connector [14:03] actually this is mainly for 2m stuff, so loss isn't as much of an issue than when receiving 433 [14:04] I find N-Types better than PL239 every time [14:04] chains of them, then they add up, but one adaptor in there is hardly going to be noticeable [14:04] or even PL259 !! [14:04] Yeah. Morseman - N's are grwat :) [14:04] and great, too [14:05] I use them at HF too, as all my system is N type [14:05] mechanically the PL/SO are very poor [14:05] NigeyS (Nigel@cpc5-cdif14-2-0-cust382.5-1.cable.virginmedia.com) joined #highaltitude. [14:06] You can get better PL259s which are more like the N-Type in the way you make off the cable into them [14:06] The clamp ones are much better than the cheap screw types [14:06] Problem is the TS2000 has N-type on 70cm and SO239 on 2M port here [14:06] Action: SpeedEvil looks at his box of belling-lee connectors. [14:07] Could you microwave tins of beans and use that as a pulse detonation engine if you had enough tins of beans and enough microwave energy? [14:07] SpeedEvil: oh man [14:07] and a dual band colinear with one cable... [14:07] that's a pain [14:07] SpeedEvil: theres a bunch of equipment at uni with those [14:07] do you just have to reconnect when you switch band? [14:08] Morseman: duplexer! [14:08] Morseman: Duplexer / Triplexer solves that. [14:08] Even *more* losses... [14:09] Morseman: depends on the diplexer [14:09] All of them have losses... [14:09] although I get annoyed as my Triplexer has an so239 on the output. [14:09] i've built one with about 0.3dB insertion loss [14:09] I just plug and unplug [14:09] Morseman: get a switch [14:09] depends what you're after. I've mostly used it for voice comms into a GP15 up high so the loss isn't too bad. [14:09] and stop stressing about 0.5dB of loss [14:10] Plan is N-Type plug and a adapter on the 2M port - being the less prone to losses port [14:10] Switch! Now we *are* talking losses!!! [14:11] Morseman: srsly. you might loose 0.5dB [14:11] its going to be better than destroying your connectors due to constant unplugging and plugging [14:11] Relay might be a bit better - if a proper 50 ohm impedance type [14:11] although when trying mobile HAB with andrew_apex. I did wonder if the duplexer/triplexer might have helped when we also have inter car comms on 2m. [14:11] I daren't mention what's on my antenna cable :p [14:11] just get a bloody duplever and be done with it [14:11] Well, was on till it broke and I replaced it [14:11] whenever I keyed up on 2m it wiped out the baloon [14:12] ah yes - inter car 2m, APRS and typing to rx a balloon aren't a good combo :P [14:12] 3rd harmonic... [14:12] and sheer RF blanketing [14:12] I've used diplexers as filters to stop the desense on cross band [14:12] Even if not harmonically related it can just blank out the incoming signal by sheer amount of energy [14:12] on one of the university minibuses, transmitting on 2m wipes out the fm radio [14:12] thought was duplexer/triplexer on the ic7000 recieving the HAB might have acted as a decent filter (of course a 70cm bandpass would be better) [14:13] diplexer ised as a LPF on the 2mtr tx and as a BPF/HPF on the 70cm rx [14:13] That's why living next to a pager site can be a right PITA [14:13] worked well [14:13] we have great fun with our voice repeater payloads [14:14] we had desense issues last flight, as the aprs payload was giving us grief [14:14] Flying large copper tubes as filters could be a bit of a problem Darkside... [14:14] but we think we've sorted it out for the next time we fly it [14:14] my amsat system has 100W tx on 2mtrs and rx ant on 70cm is only 6ft away [14:14] Morseman: yeah... :P [14:14] Morseman: its a crossband repeater [14:14] 70cm in, 2m down [14:15] That's not quite as bad as in band... [14:15] but it needs better input filtering [14:15] cuddykid (~acudworth@128.243.253.217) left irc: Quit: cuddykid [14:15] we also have a few wavelength separation on the 2 antennas [14:15] even with the desense it worked pretty damn well last flight [14:15] had 44 unique callsigns access it [14:16] also hanging the ants below eachother so they are in eachothers null [14:16] yep [14:16] ANU5 ?

[20:14] NickB1 (~NickB@d54C3B15F.access.telenet.be) left irc: [20:17] on the side of the NTX2, it says "NBFM" does this stand for narrow band FM? And I trust that it's ssb, but it doesn't say anywhere.. [20:18] also, daveake, 14899m, nice! [20:18] narrow band FM [20:18] its not SSB [20:18] its an FM modules [20:18] but we make it do SSB [20:18] ahh, ok, and that's in the code that you sent me? I was unaware that that was a software thing. [20:19] daveake (~daveake@daveake.plus.com) left irc: Ping timeout: 260 seconds [20:19] well all we are doing is pulling the frequency of the module up and down [20:20] making an high and a low tone [20:20] yeah, reading that now. [20:20] just amending the voltage on the pin [20:20] ahh ok. [20:21] daveake (~daveake@178.103.10.149) joined #highaltitude. [20:21] the input voltage of the NTX2 = 3V which varies the frequency from 0-6000Hz [20:21] so 1Hz= 3/6000 = 0.0005v [20:21] so for 425Hz shift = 425* 0.0005 [20:22] 0.2125 volts between high and low [20:22] 425Hz? isn't it 434.xxMhz? [20:23] the center frequency (i.e turn the module on with nothing attached to it) is 434.075 or 434.605 [20:23] but that will generally be pulled down [20:23] so you will find it runs at say 434.074 [20:23] the shift is the difference between the high and low tones [20:23] ahh, so were using something a bit less than that, and it varies? or is it a standerd mesure? [20:24] varies [20:24] ok, cool. [20:24] depends how you pull the voltage up and down [20:24] if you're very clever you could use a DAC chip [20:24] but most people use a resistor based voltage divider [20:25] ok, cool. and thats also in the linking to an aurduino guide. [20:25] just be aware the input voltage is 3V on the NTX2 so if you're using an Arduino you need a bias resistor to bring it down to that (the 10k resistor) [20:25] what was the other link you sent me? I lost it. [20:25] the NTX2 has an internal 100k resistor [20:25] which one was it ? [20:26] I don't even remember. haha, ohwell. [20:26] I sent the UKHAS Wiki one [20:26] ahh, right, I can just google that. [20:26] http://ukhas.org.uk/guides:linkingarduinotontx2 [20:26] but why is there an internal resistor? and thanks! [20:27] http://www.radiometrix.com/files/additional/ntx2nrx2.pdf see page 6 [20:28] means you can use input voltages > 3V by using a bias resistor as you're creating a voltage divider [20:28] I think [20:28] someone correct me if I'm wrong [20:28] ok. cool, thanks. [20:28] (sounds about right :) ) [20:28] (evening btw) [20:28] (evening) [20:29] the aurduino uno uses 5.5v right [20:29] 5V [20:30] ok, then I could just use one of those, with a 68k resistor [20:30] 68k ? [20:30] I think I'll stick to the mini pro though, and just take the 68k one out of the guide, and switch in a 10k like you said. save some money. [20:31] yeah, its on page 6. [20:31] oh I see [20:31] use 10k [20:31] and the resistors in the guide [20:31] that data sheet is assuming you're doing FM etc [20:32] ahh. [20:33] fsphil-laptop (~phil@2001:8b0:34:1:219:d2ff:fe09:a6b9) left irc: Quit: I was the turkey all along! [20:34] Received email: Anthony Stirk "Re: [UKHAS] Launch Announcement: Friday 4th May - Chalgrove - Update" [20:34] so 10k for a 5v arduino. and no resistor for the 3.3v? [20:34] well as the Wiki entry [20:36] in the wiki its a 5v arduino, with a 10k resistor [20:37] smrtz: Which resistor are you talking about? R3? [20:38] yeah, jdtanner. [20:41] with the 3.3V Arduino you can loose that 10K resistor (the bias one) [20:41] Not sure how your electronics are&but it might be worth having a read of http://blog.jgc.org/2011/01/calculating-rather-than-experimenting.html [20:42] cool, thanks Upu, and jdtanner I'll check it out., [20:42] an http://blog.jgc.org/2011/01/gaga-1-flight-computer-radios-first.html [20:42] These are very useful, as well as having a good read about voltage dividers [20:42] :) [20:43] yeah thats a good article [20:44] That shift corresponds to a difference in voltage on the TX pin of 0.255V [20:44] at least we agree :) [20:44] haha&true :) [20:45] his RTTY code is tidy too [20:45] The only difference is that there down't appear to be a bias in that article&might be a bit confusing [20:46] yeah it might work [20:46] wire it and check the voltages with a meter [20:46] shame the AVR doesn't have a DAC [20:46] would make this a tonne easier [20:47] I got some samples from TI [20:47] not done anything with them yet but they didn't look too complex [20:47] they're easy enough [20:48] ok, so I FM is frequency modulation, ssb is single-sideband modulation. what's the diffrence? is it the shift size? [20:48] SSB is a type of AM [20:48] AM = louder quieter [20:48] uhh, what? [20:49] FM = frequency changes [20:49] oh [20:49] thats why the varying voltage changes the shift [20:49] gb73d (gb73d@88-110-59-156.dynamic.dsl.as9105.com) left irc: Quit: Whoosh we're gone [20:49] yep [20:49] more power = more volume [20:49] if by volume you mean amplitude, then no [20:50] FM has constant amplitude [20:50] information is encoded in instantaneous frequency [20:50] i thought ssb was its own thing. and volume such as loud? [20:50] http://en.wikipedia.org/wiki/Single-sideband_modulation [20:51] SSB is AM with suppressed carrier, and one sideband lopped off [20:51] hence "single sideband" :) [20:51] tbh its complicated [20:51] to quote Vic Reeves [20:51] "How does it work Bob" [20:51] "I don't know but it just does" [20:51] lol, ok. I guess I should start reading. [20:51] woo woo [20:56] whats the diffrence between amplitude and volume, as in loudness? [20:57] amplitude is the only one that has a defined technical meaning [20:57] thanks [20:59] and do you use LSB or USB? [20:59] most flights use USB [20:59] is there a reason? [20:59] that comes from ham convention [21:00] ok, so it's easier to recive? [21:00] traditionally LSB below 10MHz and USB above [21:00] no they're exactly the same [21:00] it makes no technical difference [21:00] ok. [21:01] they are mirror images so if you get your wires the wrong way round switch your radio to LSB [21:02] lol, interesting, or I could just fix the wires [21:02] as long as you and your listeners know what mode to use [21:02] it's not an issue [21:02] though as i say, most HAB flights are USB [21:02] ahh [21:03] yup smrtz or hit "RV" in dl-fldigi [21:03] =reverse [21:03] my pictures are wrong on the wiki [21:03] it shows the radio on LSB as I had the wires wrong [21:03] I'll correct it one day [21:03] the uks guide uses LSB, so I'll have to check that [21:03] lol Upu, that explains that. [21:04] I'll correct that its confusing [21:05] nosebleedkt (~nosebleed@ppp046177103086.dsl.hol.gr) left irc: Quit: If you run, you only gonna die tired [21:06] ok, cool I think I have a better understanding of that now. [21:09] any guides as to how to connect the GPS modual? UPu, I have the one of the level convertor I guess the pins line up the same on the mini pro? [21:10] http://ava.upuaut.net/store/wiki/doku.php?id=levelconvertor [21:10] very work in progress [21:11] that board isn't for sale yet [21:12] yeah, thats the one I have now. everything works the same with the 3.3v arduino? RX still goes to pin 4? TX to 5? [21:12] if you're using software serial and thats what you've defined in the code yes [21:13] but be aware the uBlox modules aren't great with software serial [21:13] hence me dropping the baud rate to 4800 in the code [21:14] I do have code for using it with the hardware UART on the Arduino [21:14] but not put it on yet [21:15] ok great, thanks for the help, you to jonsowman. and yeah, the ukhas arduino guide recomends a 50 or 300 baud. I'll probobly use 300, is that fast enough for real time transmissions? [21:15] 50 and 300 are both fine [21:15] you can't go much higher than that using narrowband FM RTTY [21:15] awesome, thanks [21:15] start with 50 [21:15] make that work first [21:16] ok great, thanks [21:19] gonzo-mob (~AndChat18@host-89-240-126-231.as13285.net) left irc: Read error: Connection reset by peer [21:19] gonzo-mob (~AndChat18@host-89-240-126-231.as13285.net) joined #highaltitude.

[21:34] looked like some interesting experiments on there [21:34] We're planning to fly it a couple more times in the next few weeks. [21:34] any idea what happened the uploading/not uploading thing? [21:34] something was borked on the uploading but don't think it was your fault [21:34] can you change the call sign and checksum to all caps ? [21:35] Not sure whether we will fly HelioSS again but Vortex - almost certainly. [21:35] Will do. [21:36] NigeyS (Nigel@cpc5-cdif14-2-0-cust382.5-1.cable.virginmedia.com) left irc: Read error: Connection reset by peer [21:36] HelioSS was a little disappointing. I was expecting some temperature differential on the different colours. [21:36] And then the parachute got tied in an almighty knot (which I haven't yet untied) [21:37] The HelioSS parachute was a prototype for one which landed on Titan about 7 years ago. [21:37] how old is it? [21:38] Built for a wind tunnel test (which I did) 20 years ago :) [21:39] excellent! [21:39] Shame it ended up in a knot. [21:40] Got some good photos of the plumet to earth from HelioSS. I will try to post some over the weekend. [21:40] Also got end to end HD video from Vortex. [21:40] And probably lots of data but I still have to check [21:41] HD video is on my todo list [21:41] We flew a ReplayXD. Nice camera and weighs next to nothing [21:42] ... was pointing upwards, though. Lots of nice parachute photos :) [21:42] well if you've got a nice parachute, best to get some photos of it in action :) [21:44] Need to look at the video and data to see if we learned anything [21:46] MoALTz (~no@host-92-8-226-64.as43234.net) joined #highaltitude.

[22:49] I'm concerned about getting a power supply that has the correct current... [22:50] jdtanner: When you sit on a table that can support 500 kilos, do you weigh 500 kilos? [22:53] True, but I'm concerned that I don't know if I weigh 510kg [22:53] ;) [22:54] it's a low power radio [22:54] I'm just dilly dallying as I don't want to pop the radio given that its the only one we could find/afford [22:54] you're not going to stress your psu unless it's tiny [22:54] but I'm the same, I've only used batteries in mine so far [22:55] Well, that might be the safest way forward. TBH, I hate electricity&always have&so the prospect of blowing up a radio petrifies me :) [22:56] jdtanner: The circuit determines what current it draws from the supply - like your weight determines how much the table supports [22:56] I don't like mains electricity [22:56] that stuff scares me :) [22:57] Action: SpeedEvil was pondering a 11kVac battery charger.

[22:58] The problem is I want to get a supply that will be able to provide the necessary current&but cheaply :) I'm a northerner afterall [23:00] Also, I'm presuming that if I supply 12V instead of 13.8V it will still work. [23:01] yes [23:01] There were a couple of supplied linked last night [23:01] A PC power supply will work. [23:01] I missed them I think&stupid broadband [23:01] - but may be very noisy [23:02] I'll look though the logs. I was just wondering what everyone else was using&but the answer seems to be batteries :) [23:03] In short - any 12-13.8V power supply - regulated - of over 4A or so should work - maybe less current if you only transmit on low power, or don't transmit at all [23:03] Brill, I wont be Tx'ing for a while [23:04] Thanks all [23:06] Righty ho&off to bed to dream about c-cell batteries and buggy arduino code :P [23:06] heathkid (kvirc@unaffiliated/heathkid) joined #highaltitude.
