[10:03] <OZ1SKY_Brian> Hi Mike, trying here, heard something
[10:05] <SA6BSS-Mike> ok, its tx twice every 2 min
[10:06] <OZ1SKY_Brian> shift about 600hz?
[10:06] <SA6BSS-Mike> tune in to 144.599 it should be around 2300 center

[10:07] <OZ1SKY_Brian> ah yes my bad

[10:46] <OZ1SKY_Brian> hearing it but having problems to decode
[10:47] <SA6BSS-Mike> how wide are your receiver filter banwith in dlfldigi?
[10:48] <OZ1SKY_Brian> set to 200 atm
[10:49] <SA6BSS-Mike> ok, Im up to 420 but as long its inside it should work
[10:53] <Darkside> the wider the filter bandwidth is, the poorer the decode performance will be
[10:53] <Darkside> it needs to be just wider than the signal for optimal performance
[10:55] <SA6BSS-Mike> yes, but it realy just benefits at the tiem you are about to loose signal /end of LOS and then it does not mather realy as you gana lose it anyway

[13:01] <TT7> hi everyone
[13:01] <TT7> I've recently finished making a batch of superpressure balloon envelopes
[13:02] <TT7> I used a custom heat sealer and was a little more careful with pre-stretching this time
[13:03] <TT7> also used polarized light and filter to highlight deformations in the material.. that was quite interesting
[13:03] <TT7> there are three different envelope types/sizes
[13:04] <TT7> once I get hold of some hydrogen and the weather is right, they will be launched with my TT7B tracker
[13:05] <TT7> I've summed up the making of the envelopes in a blog post if anyone s interested
[13:05] <TT7> https://tt7hab.blogspot.com/2019/09/the-superpressure-balloons-vol-3.html
[13:07] <PE2BZ> SA6BSS-Mike, TNX info, did inform ¨the crew¨ over here.
[13:08] <SA6BSS-Mike> great, should according to the hysplit be there by tuesday morning
[13:09] <SA6BSS-Mike> TT7: tnx for info, will have read!
[13:09] <PE2BZ> Assuming it needs a bit of sunlight ?
[13:10] <PE2BZ> I don´t know if you need facebook to view this launch but a pico got stuck in the tree, with 2 heart shaped balloons, and the succeeded to get is released in the end of the movie. https://www.facebook.com/c.wlazlak/videos/2687887237911214/?fref=mentions

[14:32] <Tim_L> Hello, anyone know what kind of connector the moonraker zl special yagi 70cm uses?
[14:40] <SpacenearUS> New vehicle on the map: 03DK0LG - 12https://tracker.habhub.org/#!qm=All&q=DK0LG
[14:40] <PE2BZ> Does it come with a -N extension behind the order / type number ?
[14:42] <PE2BZ> Tim_L, Connection: direct connection ? That could mean that the coax cable is wired directly into the radiator box ?
[14:45] <PE2BZ> the 12 elements version gives a link to an png which gives a bit of a clue, no connector, coax to driver element.
[14:47] <Tim_L> pe2bz: oh okay thanks, yeah it's not very clear on the
[14:47] <Tim_L> 7 element*

[14:51] <PE2BZ> I might consider the 12 element for myself, short boomlength, and I was looking for a HAB antenna for in the top of the rotator. Can assemble inside, feed with Aircell 7 (only 7 meter needed) make all watertight and mount it.

[15:14] <SA6BSS-Mike> Tim_L: look for another yagi, its a PAIN to assamble
[15:18] <SA6BSS-Mike> PE2BZ: the tracker should start to make noise around 21° but it can take some time before its fully operational
[15:18] <SA6BSS-Mike> it ran down to 18°
[15:21] <Tim_L> SA6BSS-Mike: thanks for advice, I may well end up building a simple yagi
[15:21] <Tim_L> rather than buying a pre-made one
[15:22] <SA6BSS-Mike> yes, that fun as well :) we have every year a couple of buyer looking for advice how to assamble it, its comes with a pieze of coax and a variable capacitor to adjust it, its not verry clear how to do so
[15:23] <SA6BSS-Mike> guess you arenot close to Sweden, I have a 20ele and a 7 ele for sale :)
[15:30] <Tim_L> aw haha alas not, I'm uk based :P

[17:54] <Tim_L> https://www.amazon.co.uk/Helium-King-Small-Gas-Cylinder/dp/B000KPMSSW
[17:55] <Tim_L> The amazon page claims over 98% purity...
[18:04] <SA6BSS-Mike> I have bought gas in tanks just like that and I have not notised any differance in float altitude compared from using gas from "big" refill tanks, even toght its often climed that those "party" balloon tank is mixed with air, I dont think they are.
[18:05] <SA6BSS-Mike> Ive tryed this back then https://www.partykungen.se/heliumkit.html?gclid=CjwKCAjwzdLrBRBiEiwAEHrAYpk9yhWQQA98jAM6eANg21oTeQtP-PJJsuPVJsyRuU5IGDTeceEM_hoCNPMQAvD_BwE#15563-2

[18:23] <Tim_L> according to this official looking website https://ebpcouncil.eu/the-framework/helium party balloon helium should be between 92%-98%
[18:24] <Tim_L> I guess I'll try out the helium king one anyways and report back :P
