[11:11] <chris_99> does that AWS thing, do uplink to your satalite too out of interest? and also how much does a cubesat cost to launch? i'm guessing not cheap
[11:12] <russss> most cubesats end up getting actually launched for free
[11:12] <chris_99> intriguing
[11:12] <russss> but they are still not inexpensive to develop
[11:13] <chris_99> gotcha, i'm curious about the MCU/... they use, if they're rad hardened etc.
[11:13] <chris_99> i guess probably not?
[11:13] <russss> it varies a lot.
[11:13] <fsphil> and if you do, *please* publish the spec of the telemetry format :)
[11:13] <chris_99> heh
[11:13] <russss> SSTL put an android phone up a few years back
[11:14] <chris_99> haha wow
[11:14] <chris_99> how did the comms work with that
[11:14] <russss> I think it additionally had a microcontroller
[11:14] <chris_99> gotcha
[11:14] <russss> but I think cubesats generally don't have radiation-hardened components
[11:14] <russss> it does vary though, there's a huge variety
[11:15] <zyp> I guess cubesats usually don't have long enough lifespans to have to worry about radiation hardening
[11:15] <russss> they're also usually in a fairly low orbit so they're not subject to too much radiation
[11:15] <russss> and if they reboot occasionally it's not usually a huge deal
[11:16] <fsphil> I imagine the biggest risk is to the flash memory
[11:16] <chris_99> hmm yeah, what happens if that gets corrupted
[11:17] <chris_99> i wonder if you can have 'boot' data in multiple parts of it

[11:58] <Darkside> Bozzy: can't hear it here! (... but I am in Australia)
[12:02] <mfa298> at 434.550 it could be some ISM device, Amateur Radio or maybe even Military. It's potentially quite localised to you though so we're likely all guessing
[12:09] <dbrooke> nothing currently on there in N. Cambs. (it's actually a long (enough that I still have a single channel crystal controlled radio) established local chat frequency for me and some friends)
