[00:04] <jcoxon> natrium42, whats this coax for?
[00:04] <jcoxon> radio? if so you want 50ohm, tv cable etc are 75ohm
[00:04] <natrium42> for my HF antenna
[00:04] <natrium42> yeah
[00:05] <natrium42> i will probably order from ebay...
[00:05] <jcoxon> i think rg-6 is 75ohm
[00:06] <natrium42> i will most likely get RG-8
[00:07] <jcoxon> cool

[00:43] <SpeedEvil> Err - 8 miles on 2 watts with little antennas?
[00:43] Action: SpeedEvil doubts seriously.
[00:45] <SpeedEvil> 60 times the power = about 8 times the range. Call it 10 with the antennas.

[20:02] <Laurenceb> hello
[20:02] <SpeedEvil> Lo.
[20:02] <SpeedEvil> get earlier message?
[20:04] <Laurenceb> yeah
[20:04] <Laurenceb> I lost the link to the datasheet
[20:05] <Laurenceb> got it?
[20:05] <Hiena> Muahahaha... Now i have too much VHF output power...
[20:05] <SpeedEvil> No. However from memory, there is a diode from output to input, and you can't put more than 5mA through it.
[20:05] <SpeedEvil> Or was it 50mA
[20:06] <Laurenceb> I'll take a look on the farnell site
[20:07] <Laurenceb> 113-2756 is the part no
[20:08] <Laurenceb> ah yes 5ma, thanks
[20:12] edmoore (n=edmoore@pomegranate.chu.cam.ac.uk) joined #highaltitude.
[20:14] <Laurenceb> is there a standard current for rating zener diodes?
[20:14] <SpeedEvil> The number on the tin.
[20:14] <Laurenceb> i.e. is a 3.3v zener 3.3v at x ma of current
[20:14] <SpeedEvil> a 1W 5.1V diode will dissipate 1W at 5.1V
[20:14] <SpeedEvil> The curve is alas not very sharp.
[20:15] <Laurenceb> I mean the voltage drop is a function of I
[20:15] <SpeedEvil> yes - wattage/voltage
[20:16] <SpeedEvil> So 190mA or so for a 5.2V 1W diode

[22:01] <Laurenceb> how do I printf a degree sign?
[22:02] <SpeedEvil> depedns on the charset
[22:02] <SpeedEvil> copy and paste
[22:06] <Laurenceb> hmm ok how do I printf a constant ascii character without defining it?
[22:07] <Laurenceb> is there some sort of html style syntax?
[22:07] <SpeedEvil> printf("\x45")
[22:07] <SpeedEvil> or is it that
[22:08] <SpeedEvil> printf("%x45")
[22:08] <SpeedEvil> prints hex 45
[22:08] <Laurenceb> yes
[22:08] <Laurenceb> but anyway
[22:09] <Laurenceb> so I can use the normal datatype syntax, just with the data afterwards?
[22:09] <Laurenceb> wont tha by parsed as %x then "45" ?
[22:10] <Laurenceb> i.e. look for some hex argument and output "45" ?
[22:10] <SpeedEvil> yes - foo="\0x45"; printf("%s",foo); IIRC
[22:10] <SpeedEvil> will output char 45 too
[22:10] <Laurenceb> sure
[22:10] <SpeedEvil> (foo will need to be a char *)
[22:10] <Laurenceb> but I want to avoid that
[22:10] <SpeedEvil> Sorry - what are you trying to do?
[22:11] <Laurenceb> and do it all with the argument string that printf takes
[22:11] <Laurenceb> like in html
[22:11] <Laurenceb> where you can insert ascii character codes
[22:12] <SpeedEvil> There are several ways.
[22:12] <Laurenceb> so printf("Hello world"); would be done using character codes instead of the actual characters inside the parenthises
[22:13] <SpeedEvil> printf("%x20%c%s%s",32," ","\0x20") will print four spaces
[22:15] <SpeedEvil> Or not.
[22:16] <Laurenceb> %x20 is wrong?
[22:16] <Laurenceb> at the start, does that work/
[22:19] <SpeedEvil> yes, no, it's wrong
[22:19] <SpeedEvil> I was tired, and looked at man printf, whihc of course mislead me
[22:19] <SpeedEvil> \x20
[22:19] <SpeedEvil> that's not actually printf interpreting it though
[22:19] <SpeedEvil> that's the normal string literal interpretation at compile-time
[22:20] <SpeedEvil> When the compiler looks at a string, and converts any \n, ... into literal returns or whatever
[22:21] rharrison (n=rharriso@ left irc:
[22:25] <Laurenceb> ah so \x20 becomes ascii char 20 at compile time?
[22:25] <SpeedEvil> hex 20
[22:25] <SpeedEvil> dec 32
[22:25] <SpeedEvil> space
[22:25] <SpeedEvil> you can also use octal - \222
[22:27] <SpeedEvil> Or decimal - \032
