[12:02] <rjharrison> Hey junderwood how is tomorrow looking?
[12:02] <junderwood> Wet!
[12:02] <rjharrison> :(
[12:02] <rjharrison> Saturday still on?
[12:02] <junderwood> But it's the best chance for the next couple of weeks so we're going to try for a launch
[12:02] <rjharrison> Ok cool
[12:02] <rjharrison> Have you managed to make the code updates?
[12:03] <junderwood> ... unless the met changes over the next 12 hours
[12:03] <junderwood> ... like it has been doing every 12 hours for the last week :-(
[12:04] <junderwood> Just working on the code updates ATM. Will try to upload a couple of strings to the server once I'm done
[12:04] <rjharrison> If you can manage to send some audio again with the changes applied that would be most cool! Especially if you want tracking support.
[12:04] <junderwood> OK. Will do.
[12:05] <rjharrison> I'm going to be in a meeting tomorrow so I'll need to make sure it is all working tonight
[12:05] <junderwood> :-)
[12:05] <junderwood> Is your rig able to follow the frequency drift?
[12:05] <rjharrison> Yep ish
[12:06] <rjharrison> I have CAT too so I can change freq from iphone
[12:06] <junderwood> That will go down well in a meeting!
[12:07] <rjharrison> Hehe it can be boring at times
[12:07] <rjharrison> and we have a few breaks

[20:26] <rjharrison_> nice
[20:26] <rjharrison_> Evening jcoxon
[20:26] <rjharrison_> junderwood how are teh code mods going
[20:27] <junderwood> Hopefully done. I sent you a couple of wavs a few hours ago
[20:27] <rjharrison_> Ok I'll pull them down now and get them tested
[20:27] <rjharrison_> You still on for tomorrow
[20:28] <jcoxon> junderwood, i let your message through the google groups moderation :-p pleasently it was the first email that wasn't do do with dodgey videos
[20:28] <junderwood> Ta
[20:28] <jcoxon> you can now email unmoderated :-)
[20:28] <rjharrison_> junderwood I'm having challenge sorting out the php for he checksum as there is no conveniant unsigned char type

[20:29] <junderwood> convert to shorts then mask?
[20:29] <junderwood> (frequently)
[20:29] <rjharrison_> I'll try to implement using a mod 256 on the value
[20:30] <rjharrison_> assuming it works on 8 bit an rolls over on 256 back to 0
[20:30] <rjharrison_> s/an/and
[20:30] <junderwood> sounds sensible.
[20:32] <rjharrison_> Do you have the c function handy for passing a string;
[20:32] <rjharrison_> ?
[20:32] <junderwood> ?
[20:32] <junderwood> Do you mean parsing?
[20:33] <rjharrison_> junderwood yep
[20:34] <rjharrison_> If you have char * checksum (char * string){...}
[20:34] <rjharrison_> or somthing like that
[20:34] Action: rjharrison_ thinks paste bin
[20:35] <rjharrison_> I guess you must have the function in the uC code
[20:35] <junderwood> Are you looking for bool verifyChecksumTCP(const wxString &line) const;
[20:35] <rjharrison_> Yep
[20:35] <rjharrison_> That will do
[20:36] <rjharrison_> I assume it calcs CS and compares
[20:36] <junderwood> Yes.
[20:37] <junderwood> E-mailed to you
[20:37] <rjharrison_> thanks
[20:37] <junderwood> Very wxWidgets ish I'm afraid
[20:40] <rjharrison_> junderwood fine
[20:40] <rjharrison_> I'll strip out and pop in a quick c function
[20:40] <russss> looks like my new USRP card will arrive tomorrow, just in time to miss the launch :P
[20:40] <russss> also I don't have an antenna.
[20:41] <junderwood> wxString is almost compatible with std::string if you plan to use c++

[20:58] <rjharrison_> junderwood is the checksum in UCASE on both payloads it looked like it was different on each in the logs
[20:59] <junderwood> different on each I'm afraid. I used sprintf on B2 but had to do it the hard way on BC which ended up with caps
