[07:42] <ly2en> SA6BSS-Mike: last question if you don't mind, so I got the larger bit tested with 27mhz crystal and it looks firm
[07:42] <SA6BSS-Mike> ok
[07:42] <ly2en> the carrier seems to be offset -2khz
[07:43] <ly2en> 14.095300
[07:43] <SA6BSS-Mike> you use a tcxo?
[07:43] <SA6BSS-Mike> low ppm
[07:43] <ly2en> it's probaby just xo
[07:43] <ly2en> should i change the ctc value to make it align?
[07:43] <SA6BSS-Mike> they tend to be right spot on, just a few hz out
[07:43] <SA6BSS-Mike> ah, dont launch that
[07:43] <SA6BSS-Mike> that will drift out of controll
[07:43] <SA6BSS-Mike> as sson it goes over 1500m
[07:44] <SA6BSS-Mike> you need a 0,5ppm one
[07:44] <ly2en> https://pasteboard.co/JTLc0aJ.png
[07:44] <SA6BSS-Mike> I would change the xo setting
[07:44] <SA6BSS-Mike> #define F_XTAL 25999972
[07:45] <ly2en> aha
[07:45] <ly2en> let me give that a try
[07:45] <ly2en> so in my case that would be 2_6_999972
[07:45] <SA6BSS-Mike> by the way, I have tested the sim28ml and Quecetel L70R, no go with flight mod

[07:46] <SA6BSS-Mike> I just did , its not working'
[07:46] <ly2en> 10km+ it should not
[07:46] <SA6BSS-Mike> exactly, even after sending flightmmode string to the gps it stil wont work
[07:47] <ly2en> SA6BSS-Mike: i will tell you a secret I am working on a completely new design codenamed "the jetpack": https://pasteboard.co/JTLcZo7.png
[07:47] <SA6BSS-Mike> but be my guest, you might finds the magic formula :)
[07:48] <SA6BSS-Mike> hehe, yeah, looks wery ,uch like a jetpack :)
[07:48] <ly2en> that's going to be similar in design, just set for more power saving
[07:48] <SA6BSS-Mike> ublox seems to have a max altitude of 12200m before flight mode is needed
[07:49] <SA6BSS-Mike> 12160m works but not 12260m
[07:49] <SA6BSS-Mike> more powersaving, how you gona do that?
[07:51] <ly2en> well to start from, the delay() function on atmega328p is costly
[07:52] <ly2en> motto for the software, use fast clokc, sleep alot, wakeup quickly
[07:53] <ly2en> in terms of hardware, my colleague has done few tricks on the layout to see if that will work

[07:56] <SA6BSS-Mike> cool, what really mather is to get the startup current as low as possible, to get an as early power on on the board and as long runtime as possible, as its solarpowerd (I asume that) enegergi is in abundance and thats the really only time you have to think about low power
[07:56] <SA6BSS-Mike> you can step the power yp from the 5351 it have 4 power levels
[07:57] <SA6BSS-Mike> and use max7c the low volt module
[07:57] <ly2en> now if i remember correctly the gps is not being put to sleep and it operates all the time except when wspr is being sent
[07:57] <SA6BSS-Mike> indeed
[07:57] <ly2en> standby for u3 is 500uA and backup mode is as low as 7uA
[07:58] <SA6BSS-Mike> tcxo and 328 is 3mA at 1Mhz
[07:58] <ly2en> maybe we can spare those 493uA for 100mW beacon :)
[07:59] <SA6BSS-Mike> if you goint to run it as a battey powered beacon, yes, makes sence

[09:06] <ly2en> i think the issue with wspr being off freq does have something to do with the 8mhz
[09:06] <ly2en> because even the packet is sent too fast

[11:11] <michael_haberler> I see I can retrieve the history of a sonde flight like so:  https://sondehub.org/card/S0220077
[11:11] <michael_haberler> is that a stable link which is OK to reuse in an another application - that might generate some traffic?
[11:14] <Darkside> no
[11:14] <Darkside> that api is old
[11:14] <Darkside> and expensive
[11:15] <Darkside> it needs to be switched to the new sondehub v2 stuff

[11:18] <Darkside> michael_haberler: that page was really intended to just be an easy way to link to a flight path map from twitter
[11:18] <Darkside> dont scrape it automatically
[11:18] <Darkside> its really intended as a summary of flight data
[11:18] <Darkside> it also needs a bunch of improvements - it would be good to be able to include stuff like stuve plots and the like

[11:42] <SA6BSS-Mike> ly2en: ok, good you got it going, yes WSPR_CTC must corspond to the speed you run on the 328
[11:44] <michael_haberler> Chris is still working on https://github.com/rittels/skewt-js but I have specifically asked him for an API to incrementally add samples to the skewt
[11:44] <michael_haberler> it also links points in the skewt bidrectionally with points along the path
[11:44] <michael_haberler> you can see it in action in the (unpublished) windy radiosonde plugin: windy.com -> left top menu -> Install windy plugin -> load plugin directly from npm -> type 'radiosonde' ; click on an ascent and click/drag in the skewt and along the path
[11:45] <michael_haberler> but the skewt-plus code is completely separate from the windy plugin so reusable without deps
[11:47] <ly2en> SA6BSS-Mike: so we can call it ground-verified now
[11:48] <michael_haberler> Darkside the plan would be:
[11:48] <michael_haberler> https://radiosonde.mah.priv.at/dev/  -> click on station with fat marker -> click on Detail at bottom of skewt -> Detail page shows.... serial number: R5030116 ...
[11:48] <michael_haberler> I was thinking of adding a link over the serial number to point to  https://sondehub.org/card/<serial>
[11:52] <ly2en> last time jlcpcb did the SMT assembly and they placed capacitors all over the pcb
[11:52] <ly2en> now this time they did put resistors all over the place (including c1 and c2)
[11:52] <ly2en> can't they get that right ?
