[00:49] <Laurenceb_> SpeedEvil: gnu assembler preprocessor
[00:49] <SpeedEvil> ah
[00:50] <Laurenceb_> no longer maintained or built into gcc
[00:50] <Laurenceb_> c preprocessor is lame
[00:50] <Laurenceb_> asm with proper preprocessor could get quite fun
[00:51] <SpeedEvil> Quite.
[00:51] <Laurenceb_> e.g. hardcoded sat lookups would be fairly simple, no external python scripts called from makefile etc
[00:51] <Laurenceb_> hardcoded would be ~30% faster than the code i linked
[00:51] <Laurenceb_> but prob unnecessary as its fast already
[00:51] <nats`> good night !

[00:52] <Laurenceb_> sige sampler + F4discovery + octave and gnuplot sitting in the middle
[00:52] <SpeedEvil> What's the typical SNR of 1ms of PRSS signal - properly locked?
[00:52] <SpeedEvil> Or is it not positive.
[00:52] <SpeedEvil> In good conditions.
[00:53] <Laurenceb_> in good conditions its big
[00:53] <Laurenceb_> like 10 to 20dB
[00:53] <SpeedEvil> hmm. I wonder if that leads to optimisations where you only look for part of the sequence for each sat. Chop say 8 sats into one code at 128 samples each.
[00:54] <SpeedEvil> If you know you have good signal
[00:54] <Laurenceb_> prob not necessary
[00:54] <Laurenceb_> i havent looked at the preprocessing yet
[00:54] DL7AD (~quassel@p5B3D4995.dip0.t-ipconnect.de) left irc: Ping timeout: 260 seconds
[00:55] <Laurenceb_> it needs to data preprocessing to words of I and Q bits
[00:55] <SpeedEvil> I guess not - with the performance you're reporting.
[00:55] <Laurenceb_> prob repeated in little blocks so that alignment can be changed
[00:55] <Laurenceb_> bit banding might help, i need to read the arm cortex programmers manual
[00:57] <SpeedEvil> I diddn't see obvious applications of bit banding when I was looking at this.
[00:57] <SpeedEvil> yes - it seems like it should help - but I couldn't work out how to get it to.
[00:59] <Laurenceb_> oh
[00:59] <Laurenceb_> it accesses individual bits?
[00:59] <Laurenceb_> i thought it allowed bit offsets into memory
[00:59] <Laurenceb_> i.e. no longer byte aligned
[01:00] <SpeedEvil> 2.5. Bit-banding
[01:00] <SpeedEvil> Bit-banding maps a complete word of memory onto a single bit in the bit-band region. For example, writing to one of the alias words will set or clear the corresponding bit in the bitband region.
[01:00] <SpeedEvil> This allows every individual bit in the bit-banding region to be directly accessible from a word-aligned address using a single LDR instruction. It also allows individual bits to be toggled from C without performing a read-modify-write sequence of instructions.
[01:00] <Laurenceb_> heh im reading the same thing now
[01:01] <SpeedEvil> :)
[01:01] <Laurenceb_> so it only gives you bit access then
[01:01] <Laurenceb_> horribly slow :-/
[01:11] <SpeedEvil> It's annoying when you meet a 'if only I could write my instruction with 100 gates of logic' problem.

[10:16] <Darkside> its awesome
[10:16] <Steve_G0TDJ> Nice, I have s5 noise most places
[10:16] <fsphil> I can hea rsomeone on 28500
[10:16] <Darkside> im currently in th middle of nowhere else
[10:16] <Steve_G0TDJ> I can't hear the DK3 or SA
[10:16] <Darkside> sonot much noise at all
[10:16] <Darkside> i think 15m might get to the UK later tonight
[10:17] <gonzo__> s9+ at mine. a wash of PLT
[10:17] <Steve_G0TDJ> Yeah, I'm right in the middle of residences and shops....
[10:17] <fsphil> just lots of noise now
[10:17] <Darkside> hearing som stations on 15m
[10:17] <Darkside> not much
[10:17] <fsphil> but there was definitly comeone calling
[10:17] <Darkside> and my antenna doesnt tune there well
[10:17] <fsphil> beingaware: call again
[10:17] <beingaware> I can hear 28.480
[10:18] <beingaware> which freq fsphil
[10:18] <LazyLeopard> 28.480 is right at noise floor here...
[10:18] <beingaware> back on 28.500
[10:18] <Darkside> i have local noise there
[10:18] <Darkside> well, a single spur
[10:18] <fsphil> I've got some noise on 28500 but give it a try
[10:18] <Steve_G0TDJ> S9 noise on .480 here
[10:18] <Darkside> i doubt 10m will work to the UK right now
[10:19] <Darkside> not without a beam and POWERRRRRRR
[10:19] <Darkside> (clarkson)
[10:19] <beingaware> MAX POWEEEEEEEER
[10:19] <beingaware> lol
[10:19] <Darkside> 400W
[10:19] <Darkside> (or more)
[10:19] <beingaware> I could always buy an amp :P
[10:19] <Darkside> arent you still an F call
[10:19] <beingaware> shut up

[10:19] <Darkside> :P
[10:19] <gonzo__> 400W, that;s intermediate drive isn't it?

[10:20] <Darkside> *cough*
[10:20] <fsphil> that's so silly
[10:21] <beingaware> just like all f calls do "10watts"

[10:21] <beingaware> perfectly build and all LOL
[10:22] <Darkside> well
[10:22] <Darkside> he does have a big 40m antnna

[10:23] <LazyLeopard> What frequency?
[10:24] <fsphil> 28500
[10:24] <Darkside> beingaware: lol
[10:24] <fsphil> USB
[10:24] <beingaware> RM italy 500v or HLA300 plus? :P
[10:24] <Darkside> KPA500
[10:24] <beingaware> to be filtered or not, that is the question LOL
[10:24] <LazyLeopard> Strong South African station on 28.502 making hearing anything low power tricky here...
[10:25] <Darkside> yeah no way will i hear him
[10:25] <beingaware> nice amp
[10:25] <Darkside> prop is rarely good to south africa from here
[10:25] <beingaware> how much

[10:27] <fsphil> yea 15M is the best bet from UK to AU
[10:27] <Darkside> dammit, IT9 on 28480 cant hear me
[10:27] <fsphil> at around 12:00
[10:27] <fsphil> UTC
[10:27] <Darkside> im hearing nothing on 15m
[10:27] <Darkside> but yes, 15m should come in about an hour ros o
[10:29] <fsphil> not hearing anything on 28480
[10:29] <Darkside> you wont
[10:29] <Darkside> he's too close for you i think
[10:29] <LazyLeopard> Heh, I'm hearing halves of two QSOs on 28.490. Neither pair can hear the other...
[10:29] <Darkside> that happens
[10:30] <LazyLeopard> IT9's probably a standard alligator...
[10:30] <fsphil> nothing on 490 either

[10:41] <Darkside> mine certainly is
[10:41] <beingaware> once shes fixed it will belt out all around vk land

[10:42] <Darkside> yup
[10:42] <beingaware> yeah, its a bit hard to get over 20m

[11:03] <gonzo__> could be tweakable for the 70cm band? Depends if it's worth thr effort

[12:35] <ike> so I was thinking how much will it cost me custom 18.100MHz xtal
[12:36] <gonzo__> probably cost you about the same as the ntx2
[12:37] <ike> xtal or custom module
[12:37] <ike> btw have you seen 18.100MHz xtal?
[12:39] <gonzo__> last time I had xtals made, they were about £12, but there will probably be a minimum order of £25. So you tent to order two xtals
[12:40] Nick change: KipK -> KipK_away
[12:41] <ike> for 12 you can get DDS + MCU
[12:41] <ike> then maybe ...
[12:41] <ike> there are car FM transmiters
[12:42] <ike> I wonder if they can be hacked for 145 instead of 108MHz
[12:42] <gonzo__> you may find off the shelf crystals ad I think 18.100 is a calling chan on an AR band??
[12:43] <gonzo__> I thought radiometrix already do a 144.800 module though??
[12:46] <ike> yes
[12:46] <ike> they do
[12:46] <ike> but they cost like dual band radio
[12:46] <ike> I's better to use dual band radio

[20:38] <Upu> Geoff-G8DHE we aren't the only people flying on Sat
[20:38] <Upu> so we'll keep you busy
[20:39] <Upu> six of ours will be in the 192khz of the FCD Pro+
[20:40] <Geoff-G8DHE> Biggest pain will be trying to decide which ones need the beam and which the colinear I suspect!
[20:40] <Upu> I could squeeze these even closer tbh
[20:40] <Upu> TCXO ftw
[20:40] <Upu> check this : http://i.imgur.com/e8Hi59C.jpg
[20:40] <Upu> the arrow shows a solder jump shorting SCK to GND
[20:41] <Geoff-G8DHE> Ook
[20:41] <Geoff-G8DHE> Is that flow soldered or ?
[20:42] <Upu> yeah reflowed
[20:42] <Upu> slightly too much solder put down via the stencil

[20:45] <mfa298_> might just be the angle but the programming header looks to be the largest part on there!
[20:45] Nick change: mfa298_ -> mfa298
[20:45] <Upu> ah well
[20:46] <Upu> http://imgur.com/7kIWCha
[20:46] <Upu> note snap off
[20:47] <mfa298> I think part of it was the angle, but makes a good point for having the snapoff
[20:47] <mfa298> hopefully you don't need to re-program it (although I see you have pads on the main board)
[20:47] <wd8mnv> snap on... snap off...
[20:48] <Upu> yeah you can edge mount a 2x3 header to it
[20:48] <Upu> if you want
[20:49] <mfa298> I wonder if the next trick would be to have some groves so you could have a push on connector like the old floppy drive connectors (thinking 5 1/4 type drives here)
[20:50] <fsphil> edge connectors
[20:51] <fsphil> they're quite long
[20:51] <mfa298> would need to find a 3x2 variant (or a couple more for extra debug/external power)
[20:52] <Upu> well wanted to retain the standard header
[20:52] <Upu> but without retaining the standard header
[20:52] <fsphil> it is handy
[20:52] <Upu> credit to Darkside for suggesting it
[20:52] <fsphil> plus it makes you very careful about programming
[20:52] <fsphil> more incentive to make sure there are no bugs before cutting :)

[20:54] <Willdude123> Hello
[20:55] <Upu> lol indeed mfa298
[20:55] <Upu> evening Will
[20:55] <Willdude123> Excited about the TYT TH-UVF9 I'm getting for christmass
[20:55] <Willdude123> *christmas
[20:55] <Upu> cool
[20:55] <Upu> I'm getting Whisky
[20:57] <Willdude123> Awesome
[20:57] <Willdude123> It's my christmas resolution to get my board done by new year :)
[20:58] <nats`> I hope you'll have more than one in 1 year :)
[20:58] <mfa298> I think I'd prefer what Upu's getting, but then I already have a collection of hand held radios
[20:58] <Geoff-G8DHE> It will help you learn Chinese as well I see "Chinese/English voice prompt"
[20:58] <eroomde> i think upu already has a collection of whiskies
[20:58] <Willdude123> My dad was going to take me to the pub
[20:59] <Willdude123> Then realised it's probably not a good idea
[20:59] <eroomde> it's fine with an adult
[20:59] <Upu> I do eroomde but you can never have too many
[20:59] <Upu> and its getting a bit low
[20:59] <eroomde> i'm hoping for binoculars
[20:59] <nats`> Willdude123 why not a good idea ?
[20:59] <Upu> thats a good present actually and something I don't have
[20:59] <Willdude123> It would probably full of drunks
[20:59] <mfa298> that's the benefit of getting more whiskey, means there's more to drink
[21:00] <nats`> Upu it'll change your life :)
[21:00] <eroomde> it's a funny feeling you get when over 25
[21:00] <Willdude123> And Oakley + Drunkards
[21:00] <eroomde> that you ought to have a decent pair of binoculars
[21:00] <Willdude123> Doesn't work too well
[21:00] <Upu> my Dad has some
[21:00] <nats`> Willdude123 a pub is full of drunk
[21:00] <Upu> I borrow his
[21:00] <nats`> that the concept
[21:00] <nats`> ...
[21:00] <Upu> lol
[21:00] <Willdude123> Oakley people are bad enough without drinks
[21:00] <eroomde> also these are image stabilising ones which I tried a few months ago, and the IS is incredible
[21:00] <nats`> they world is much brighter when drunk
[21:00] <nats`> eroomde we have that at work
[21:00] <nats`> I can't work with
[21:01] <eroomde> would be just the ticket for looking at the night sky or watching some of the random hawks and kits and stuff we get at work
[21:01] <nats`> that's confusing
[21:01] <nats`> ohhh you mean those binocular
[21:01] <nats`> my bad
[21:01] <eroomde> what's confusing?
[21:01] <nats`> I was thinking about binocular for soldering
[21:01] <nats`> we have a model with angle correction
[21:01] <eroomde> binocular for spying
[21:02] <nats`> don't say that to enjoy pretty girl is better :)
[21:02] <eroomde> my eyes are still up to unaided soldering
[21:02] <nats`> your eye yes but not your hand
[21:02] <nats`> :p
[21:02] <Upu> mine aren't
[21:03] <Willdude123> No seriously oakley is mostly full of elderly bigots
[21:03] <nats`> you mean you solder without binocular ?
[21:03] <Willdude123> That's a bit of a generalization
[21:03] <Willdude123> But they make up a significant proportion of the population
[21:03] <Upu> I solder with an illuminated microscope
[21:03] <Upu> but some of the stuff is getting so small its hard to see faults
[21:03] <Willdude123> A certain relative of mine thinks sooty is still an acceptable term
[21:03] <eroomde> i solder with my eyes
[21:03] <eroomde> they are temperature-controlled
[21:05] <eroomde> but so far for smd stuff i've been fine just with my eyes and a couple of desk lamps
[21:05] <Upu> I only use the microscope when finding issues like the above
[21:06] <Willdude123> It took me about 15 minutes to solder an 0805 the other day
[21:06] <Upu> solder one pad
[21:06] <Upu> slide component on with tweezers
[21:06] <Upu> do other side
[21:06] <Willdude123> So put a blob of solder on one pad?
[21:06] <eroomde> yes
[21:06] <Willdude123> Then put the resistor on top?
[21:06] <eroomde> yes
[21:06] <Willdude123> And then melt it?
[21:06] <eroomde> yes
[21:07] <Willdude123> And then do the other side
[21:07] <eroomde> yes
[21:07] <Willdude123> That's what I did
[21:07] <Willdude123> Still took me 15 minutes
[21:07] <Laurenceb_> right there right there
[21:07] <eroomde> what did you do for the other 14 minutes and 50 seconds?
[21:07] <Upu> lol
[21:07] <Upu> practice Willdude123
[21:07] <Willdude123> I was trying to position it
[21:07] <bertrik> the first component always takes me way longer than the rest, having to get into the routine
[21:07] <eroomde> do you have the pcb fixed so something?
[21:07] <eroomde> that helps

[21:08] <Upu> ibanezmatt13 picked it up quickly
[21:09] <Willdude123> I have a £15 maplin one

[21:09] <Geoff-G8DHE> and the right tips to suit
[21:09] <Upu> ah
[21:09] <eroomde> spend £100
[21:09] <Upu> there in probably lies your issue
[21:09] <Willdude123> It's 50w
[21:09] <eroomde> it'll be the best money you spend on electronics
[21:10] <eroomde> it's not so much about power as regulation and thermal recovery
[21:10] <Willdude123> Not sure I can afford £100 for an iron when I have radios and other expensive stuff to buy
[21:10] <Upu> http://dx.com/p/hanko-fx-888-70w-soldering-station-ac-220v-126505#.Urn4QMQ7t8E
[21:10] <Upu> £67 delivered
[21:11] <eroomde> genuine?
[21:11] <mfa298> good tools, practice, space to work and good lighting are the keys to good soldering. Without those you'll struggle.
[21:11] <eroomde> if so that's really good
[21:11] <Upu> says so
[21:11] <Geoff-G8DHE> but out of stock!
[21:11] <eroomde> i'm tempted by one of the JBC ones that everyone keeps raving about
[21:11] <eroomde> for my home lab
[21:11] <eroomde> but that's down the list as the home comes before equipment for the home lab

[21:11] <Willdude123> That colour scheme
[21:12] <Willdude123> Makes it look like a childs toy
[21:12] <Upu> better than that the Maplin actual toy
[21:12] <eroomde> i have no complaints with my weller at work though
[21:13] <eroomde> but the tip power-down thing is nice, and i can definitely see its utility in prolonging the tip life
[21:13] <Willdude123> Heh
[21:13] <Willdude123> Will think about it

[21:14] <eroomde> take it slow
[21:15] <mfa298> Willdude123: depending on which soldering iron you've got even getting a better tip for it might help
