[05:38] <Darkside> PE2BZ: tried putting the RS41 into more of a power saving mode, didnt do much
[05:38] <Darkside> ned to investigate more where the 32ma of power draw is coming from
[05:38] <Darkside> e.g. is it all the STM32, or is it shared across multilple chips on the board

[06:38] <PE2BZ> Darkside, Good morning. Thanks for the effort :-) Can you make a test version which acts like there are enough satellites and goes into deepsleep ? That way I can have a PCB on the desk and cut a few traces to check if it´s the STM32 ?
[06:39] <Darkside> yeah probably can
[06:39] <Darkside> i mean, you probably could too :-)
[06:39] <Darkside> in main.c, line 391, jut above the if statement
[06:39] <Darkside> add in some lines:
[06:40] <Darkside> gpsData.gpsFixOK = 1; gpsData.sats_raw = 8;
[06:43] <Darkside> that shoudl let it enter it

[06:50] <PE2BZ> Copied that for later today / tomorrow. 3d printing an air Y splitter to try to fill 2 halves of a 164 cm number zero balloon with about as much HE in each half.
[06:51] <SA6BSS-Mike> Darkside: https://imgur.com/3ZzTspy
[06:51] <SA6BSS-Mike> you can remove all those ic:s
[06:51] <SA6BSS-Mike> and the board should stil work
[06:52] <SA6BSS-Mike> or maby one of ldos will turn them all off,
[06:52] <SA6BSS-Mike> have not mesured the powersave but it was not that much iirc
[07:00] <Darkside> ok
[07:01] <Darkside> yeah im sure theres some way of dropping the consummption a bit more
[07:01] <Darkside> i figure putting the STM32 into a proper sleep mode should help. im not doing that properly atm
[07:02] <SA6BSS-Mike> I have a hard time beliver the stm takes that much current even at full speed.
[07:02] <SA6BSS-Mike> it realy should be in sub 10mA
[07:02] <SA6BSS-Mike> donwloading datasheet :)
[07:03] <SA6BSS-Mike> I mean, the atmega328 can run on 1-2mA
[07:03] <SA6BSS-Mike> at 3.3v

[07:11] <SA6BSS-Mike> maximal curent consumption at 24Mhz is 20mA
[07:12] <SA6BSS-Mike> thats with External clock (2), all
[07:12] <SA6BSS-Mike> peripherals enabled
[07:13] <SA6BSS-Mike> it can ofc drive periferials with its pin that will cause extra power consumtion
[07:13] <SA6BSS-Mike> *pins
[07:13] <Darkside> yeah.. i disable all the LEDS, but theres probably other stuff too
[07:14] <SA6BSS-Mike> wasnt there a full schematics amde of the rs41, i belive Isaw that a year ago, reversed eng ofc, nothing official

[07:59] <g7gpr> Hi - I'm looking for some help setting up to receive WSPR on HF. I've found various blogs on how to do it, but what is the reference that you recommend for receiving PS-80 etc?
[08:10] <Darkside> i dunno :/ not sure if he is doing somthing weird with the telemetry
[08:10] <Darkside> i suspect if you just receive it as normal WSPR it will be possible for the owner of that payload to decode it
[08:12] <g7gpr> Ah - since I could see it on Habhub, I thought it might be open. I'll try and make contact with someone who is receiving it.
