[19:20] <gordonjcp> heh
[19:20] <gordonjcp> well they're onto m6 by now
[19:21] <gordonjcp> M6FRG?
[19:21] <fnoble> was thinking 2E0FNO?
[19:21] <fnoble> FRG could be good
[19:21] <gordonjcp> oh, you're on intermediate?
[19:21] <gordonjcp> fnoble: 'cos it's like the famous Yaesu FRG-7
[19:22] <fnoble> yeah, i did the two exams together
[19:22] <fnoble> with edmoore and hallam
[19:23] <gordonjcp> cool
[19:23] <fnoble> done - 2E0FRG

[20:42] <rjharrison> jcoxon Just wanted to say thanks for the ebay pointer. Picked up the GM862 for 20 notes
[20:42] <jcoxon> hey rjharrison
[20:42] <jcoxon> coolio
[20:42] <jcoxon> will need some form of breakout board
[20:42] <rjharrison> Need to get a break
[20:42] <rjharrison> You beat me to it
[20:43] <rjharrison> I see sparkfun do them I may place an order for one and an antennea
[20:43] <rjharrison> antenna
[20:44] <jcoxon> robosavvy sell the spark fun ones as well
[20:44] <jcoxon> save on p&p as tehy are in the uk
[20:44] <rjharrison> Oh I'll have a look
[20:44] <rjharrison> Do you have an antenna
[20:44] <jcoxon> yup
[20:46] <rjharrison> ouch the breakout cost more than the module
[20:47] <rjharrison> Still better than sparkfun
[20:47] <jcoxon> :-0
[20:56] edmoore (n=edmoore@pomegranate.chu.cam.ac.uk) left irc:
[21:05] <rjharrison> jcoxon how do you get 3.8v for the gm862
[21:06] <rjharrison> linear regulator?
[21:06] <jcoxon> direct lipo :-)
[21:06] <jcoxon> they are designed to run off them
[21:07] <rjharrison> Ohh I'll have a look for one. No wonder you were so heavy :-P
[21:08] <jcoxon> what!
[21:08] <jcoxon> 3.7v Lipo cells are light
[21:08] <rjharrison> ok I'm having a look :)
[21:10] <jcoxon> the camera was what made me heavy
[21:10] <jcoxon> http://www.sparkfun.com/commerce/product_info.php?products_id=8483
[21:10] <jcoxon> 36g!
[21:11] <rjharrison> Ok I stand corrected
[21:11] <rjharrison> they are light
[21:11] <rjharrison> Good for 4hrs I'm sure
[21:12] <jcoxon> i didn't strip down the powershot with its 4AAs - that added a hell of a lot of weight
[21:13] <rjharrison> The a560 only has 2aa's so that would have saved me a bit
[21:13] <jcoxon> indeed but a560s don't do remote capture
[21:15] <rjharrison> I'm going to place with sparkfun I think as I need both battery, brakeout and antenna
[21:16] <jcoxon> the breakout is quite big which is a shame
[21:17] <jcoxon> you getting the 50pin? as you'll need to do some level conversion
[21:18] <rjharrison> Yep I think so. I thought I could get away with 3.3v cmos
[21:19] <jcoxon> yeah, that'll be fine

[21:19] <jcoxon> is your AVR 3.3v?
[21:22] gregHome__ (n=gleblanc@75.108.2.123) left irc: Remote closed the connection
[21:23] <rjharrison> humm can see the cmos levels but the atmega8l is 2.7-4.5v
[21:24] <rjharrison> can't
[21:25] <jcoxon> what voltage is its tx?

[21:32] <rjharrison> Looking, can't see it in the atmega8 pdf
[21:33] <fnoble> rjharrison, it will be the same as whatever voltage you are powering the chip with
[21:33] <fnoble> are you running it straight from the battery, or with a regulator?
[21:34] <rjharrison> will regulate it to 3.3
[21:34] <rjharrison> To be fair the current beacon is on 5.5v at the moment
[21:35] <rjharrison> The lassen iq is going to be on 3.3v if i remember correctly
[21:35] <fnoble> ok, that will be fine then, you can directly connect 3.3v logic to the gm862 im pretty sure
[21:35] <fnoble> yeah the lassen is 3.3
[21:35] <rjharrison> That's my thoughts. So they will all be happy then
[21:36] <fnoble> should be
[21:36] <rjharrison> avr + iq + gm862
[21:36] <rjharrison> This is beacon mk2
[21:36] <fnoble> oh cool
[21:36] <jcoxon> fnoble, are there any nova launches in the near future?
[21:36] <fnoble> jcoxon, there should be one soon i hope
[21:37] <rjharrison> though logomatic v2 might have a hump. I'll have to read the datasheet
[21:37] <fnoble> we are just waiting for a weather window
[21:37] <rjharrison> is this w/e out?
[21:37] gregHome (n=gleblanc@75.108.2.123) joined #highaltitude.
[21:39] <fnoble> looks quite windy
[21:39] <jcoxon> its so nearly nice
[21:39] <jcoxon> friday evening :-p
[21:41] <fnoble> hmm, its blowing directly east then
[21:42] <jcoxon> haha, just ran a forecast for 48hrs
[21:42] <jcoxon> don't launch :-p
[21:43] <rjharrison> I would like a tutorial on how to read the winds one day. Master coxon was remarkably correct with his prediction last launch. Even the bloody track concurred
[21:44] <jcoxon> it'll put me out of a job
[21:44] <jcoxon> right time to kill some aliens and save the world on the xbox 360

[23:11] <fnoble> sweet
[23:11] <jcoxon> and on 70cm band, finally got someone who was modifiying a PMR radio and heard me calling CQ
[23:12] <fnoble> chose my callsign this evening, get 2E0FRG
[23:12] <jcoxon> fnoble, excellent
[23:12] <fnoble> *got
[23:14] <jcoxon> was really nervous, now i'm quite encouraged to continue to call CQ on 433.500
[23:14] <jcoxon> told him all about high altitude ballooning - he says we should do a cross band repeater
