[10:04] <Chrischan> Hello. IDA-4FSK is only equipped with an AAA energizer and weighs 19 grams, I hope the sun warms the battery sufficiently. The goal is to cross the 19km with a 36 inch balloon. Unfortunately there are problems with the GPS reception, I hope it still receives up to the top (:
[10:04] <SIbot> In real units: 36 inches = 0.9 m

[10:09] <Darkside> ahh
[10:10] <Darkside> Chrischan: i managed to send a RS41 with a single AA a long way across australia with 2x 36"
[10:10] <Darkside> lasted about 20 hours, should have made the gap between transmissions a bit longer

[10:20] <DK6OV> Chrischan: We will see. 19 km is much for such a small balloon.
[10:23] <DK6OV> Oh, IDA has no GPS anymore. :(

[10:29] <Chrischan> 20 hours is a good value, that needs to be improved (:
[10:29] <Chrischan> IDA-RTTY made it to 18,667 meters on March 21st, 21st with 26 grams and a 36 inch balloon. The last attempt also ended with the GPS intermittent, I probably damaged the antenna again
[10:29] <SIbot> In real units: 36 inches = 0.9 m
[10:36] <DK6OV> Das ist Pech.
[10:39] <Chrischan> sie sendet die aktuelle Uhrzeit aus dem GPS Signal, noch habe ich Hoffnung

[10:46] <Darkside> Chrischan: hmm, 18km is pretty good! I was 35g and using 2 balloons, and floated at 7km
[10:46] <Darkside> about 10g free lift
[10:46] <Darkside> got almost exactly 1m/s ascent rate
[10:47] drsnik (~drsnik@gate3.ima.cz) left irc: Ping timeout: 260 seconds
[10:54] <Chrischan> Darkside. I recommend a buoyancy of 6 grams. This means that a 30 gram probe with a white 36 inch balloon rises at 0.7-0.9 m / s (during the day) to over 10 km and floats with a high degree of safety.
[10:54] <SIbot> In real units: 36 inches = 0.9 m
[11:01] <Darkside> ok
[11:01] <Darkside> will try that next time
[11:07] <DK6OV> The voltage of IDA is becoming very low. only 1.12V now
[11:13] es5nhc (~es5nhc@static-213-100-139-88.cust.tele2.ee) joined #highaltitude.
[11:23] <Chrischan> the missing GPS will probably increase the power consumption, below 1V it is slowly going to end. Tomorrow (if everything fits) a new attempt may follow.

[11:47] <Chrischan> Darkside. Another little tip for closing the latex balloon: in order to minimize inexplicable gas loss, we have recently been protecting the balloon neck with foam tape from the cable tie cutting into it. since then we have had fewer gas losses. https://1drv.ms/u/s!Av9PFEeuJmy22lwFqz7_cL5a6kBN?e=ye8mjz
[11:49] <Darkside> Chrischan: hmm, i seal the beck with a heat sealer
