[14:13] <rjharrison_> Quite common
[14:13] <rjharrison_> Infact I have had -45 b4 without the camera in there

[14:14] <rjharrison_> Things like the oscillator won't make that spec unless you pay big money but for as many as possible
[14:24] <MikeMc> do the batteries work OK down to those temps?

[15:41] <RocketBoy> rjharrison: its worse than I thought - a 20dbi gain parabolic dish on 868MHz would be approching 4m across - so basically you are being told rubbish by the antenna manufacturer
[15:44] <RocketBoy> 1m dish gain on 868 is about 9.2db - then add 6db for every time you double the diameter
[15:46] <RocketBoy> likewise I think its way optimistic to expect 20db out of a 1.5m long 868MHz yagi
[15:49] <SpeedEvil> 20db front/back ratio?
[15:51] <RocketBoy> no gain - rob was asking for 20dbi gain out of a 1.5m long yagi - where as I think 15dbi is more realistic
[15:51] <RocketBoy> for 20db think 6m long
[15:51] <RocketBoy> or rather think of an array of yagis
[15:52] <RocketBoy> 4 x 1.5m
[15:53] <RocketBoy> plus phasing harness

[17:39] <SpeedEvil> get_iplayer
[17:40] <SpeedEvil> My intenet is broken ATM tho
[17:41] <DanielRichman> is iplayer audio encoded to the same level as the video?
[17:41] <DanielRichman> I can grab the audio stream as it goes through pulseaudio; I think that's on the digital side of the analogue hole
[17:42] <DanielRichman> or i can try to get something from wireshark
[17:42] <SpeedEvil> get_iplayer grabs the whole stream
[17:42] <SpeedEvil> and outputs it as a mpeg or something
[17:42] <DanielRichman> Is that the ruby program?
[17:42] <SpeedEvil> perl IIRC
[17:43] <DanielRichman> hmm ok
[17:46] <DanielRichman> Seems to work

[17:51] <DanielRichman> you probably have all the dependancies already
[17:51] <rjharrison_> oh cool
[17:51] <DanielRichman> wget that, start a guest session or change user to nobody
[17:51] <DanielRichman> be sure to drop privs
[17:52] <DanielRichman> then ./get_iplayer lists all programs; ./get_iplayer | grep ..., use the id, download

[22:07] <rjharrison> Adv of being the IT Director
[22:07] <DanielRichman> rjharrison, hehe nice
[22:07] <DanielRichman> rjharrison, listening to your interview, very nice
[22:08] <rjharrison> DanielRichman Thanks
[22:10] Action: RocketBoy is watching video with the xyl at the mo
[22:11] <rjharrison> RocketBoy cool
[22:16] DanielRichman (n=daniel@unaffiliated/danielrichman) left irc: Remote closed the connection
[22:17] <rjharrison> edmoore the radio dj plugged the project quite a few times after i left check out 34.57
[22:18] <SpeedEvil> Anyone happen to know what keywords I should be looking for for bloodsugar monitors - IR ones?
[22:18] <SpeedEvil> Or are they so stupidly expensive ATM that they're not turning up on ebay et al.

[22:32] <SpeedEvil> ./get_iplayer --get 12337
[22:33] <SpeedEvil> just works for me - after ./get_iplayer update
[22:34] Action: RocketBoy is just listening to it now
[22:40] <rjharrison> ahh
[22:40] <RocketBoy> cool
[22:42] <rjharrison> RocketBoy I think I got most of the detail in there in laymans terms
[22:42] junderwood_ (n=chatzill@adsl.jcu.me.uk) left irc: "ChatZilla 0.9.85 [Firefox 3.0.15/2009101601]"
[22:42] <RocketBoy> yeah - i think that touched all the bases
[22:46] <rjharrison> SpeedEvil see pm
[22:50] <RocketBoy> Radiometrix tech support are getting on my nerves - I have gone through a 3 email excahnge (1 day for each email) - and they still havn't given me the answer I'm looking for
[22:51] <RocketBoy> answers tend to be "we don't think you know what your doing" - then I have to prove that i do
[22:57] <edmoore> They should be a bit more balloon friendly
[22:57] <SpeedEvil> RocketBoy: Whate're you trying to find out.
[23:00] <RocketBoy> the low pass filter roll off characteristics of the LPF on the NTX2 / TX3H - they specify the cuttof freqiency - but not the filter order
[23:00] <RocketBoy> need it to calculate PWM DAC frequency
[23:01] <rjharrison> RocketBoy perhaps you are too advanced for them :)
[23:02] <RocketBoy> I think that may be the case - but its a simple enough question
[23:04] <RocketBoy> and if they don't want to answer it they can say so - but instead they keep reffering me to other stuff
[23:04] <natrium42> rjharrison, i listened to the radio interview -- was great
[23:04] <rjharrison> natrium42 thanks
[23:04] <RocketBoy> like they told be to look at the cusf and your website
[23:05] <rjharrison> RocketBoy your joaking
[23:05] <RocketBoy> they are frendly enough - just don't answer the question
[23:05] <RocketBoy> nope
[23:05] <rjharrison> Did you tell them that you tolb me all that I know
[23:05] <rjharrison> told
[23:06] <rjharrison> Teacher Student here and I'm not the teacher :)
[23:06] <RocketBoy> similar - i told them it was me that came up with the RTTY over narrow FSK on 434MhZ
[23:07] <RocketBoy> then they told me to use a band that isn't even allowed in airbone operation
[23:10] <RocketBoy> anyway lets hope that tomorrows email exchange will result in an answer
[23:10] <SpeedEvil> RocketBoy: measure it?
[23:10] <SpeedEvil> RocketBoy: sinewave sweep - and see/
[23:10] <SpeedEvil> ?
[23:10] <RocketBoy> difficult - i'd have to measure it that the reciver
[23:11] <SpeedEvil> set reciever to wideband FM, and it should work/
[23:11] <SpeedEvil> ?
[23:11] <RocketBoy> then that means that the reciver roll off comes into it too
[23:11] <SpeedEvil> Or set ssb reciever to very edge of signal
[23:11] <RocketBoy> na the recives have a baseband filter too
[23:12] <SpeedEvil> If you have a 20KHz modulation, and set the SSB reciever to pick up the outside 1KHz of this, you will get a very good idea of the rolloff
[23:12] <SpeedEvil> As you increase the frequency of the modulation input
[23:13] <RocketBoy> not sure about that - i'd have to visulaise what is going on with FM
[23:14] <SpeedEvil> hmm
[23:14] <RocketBoy> possibly - really need a spectrum analyser
[23:15] <RocketBoy> anyway - just answering my Q is the smallest amount of work for me
[23:16] <RocketBoy> Anyway I suspect that is just a simple RC 1st order filter - so I could just assume that as its a worst case anyway
[23:16] <RocketBoy> just that if it is better then I can get more out of the PWM DAC
[23:18] <rjharrison> right nights
