[20:03] If I look at the HabHub tracker map and I see a balloon there is a green and a blue circle around it. What is the distance from the balloon to those circles? [20:04] ah, that is an easy question with a clear answer! :D [20:04] the blue circle is the so-called radio horizon [20:04] Think so but I don't know. I am to this. ;D [20:05] I mean new to this hobby..... [20:05] that's as far as the balloon can 'see' limited by the curvature of the earth, depending on the altitude, and anyone inside the circle should be able to see the ballon [20:06] Ok Bertrik thats ok for me. Just see a balloon in SP Poland and the blue circle covers my area. [20:06] the green line is a similar circle, just not at 0 degree, but 5 degrees (or so) above the horizon [20:07] so if you're inside the blue circle, you have a reasonably good chance of receiving the balloon telemetry [20:07] and if you're inside the green circle, and you DON'T receive it, your receiver is pretty deaf :) [20:07] Understand it. So lets keep a eye if I can receive something in the next hour. [20:08] JohanM: what kind of receiver do you have? and what kind of antenna? [20:09] Yesterday I install the IMG file and run it now on a Raspberry. I am a long time a radio operator but never was involved in this kind of hobby. [20:11] with an rtl-sdr you can probably see the balloon in the waterfall [20:11] RTL-SDR dongle V3 and the ant is a vertical for the moment. But my location is not that good. It is a small city, I am close to the centre so pretty much a lot of qrm around me. [20:11] You need line of sight to the horizon with no buildings in the way. Not sure about trees but if you are on the limit they won't help. [20:11] people often use a band filter with it, to limit out-of-band interference [20:13] Yes I need that to, but because this is my second day to watch this I have to do some work to get the RX and ant a bit better. [20:13] ctarpy (~ctarpy@static-84-9-38-95.vodafonexdsl.co.uk) left irc: Remote host closed the connection [20:13] at our hacker space we used a colinear antenna + band filter + rtlsdr to track balloons, worked ok [20:13] and dl-fldigi as the decoder software [20:13] band filter build by yourself? [20:13] ctarpy (~ctarpy@static-84-9-38-95.vodafonexdsl.co.uk) joined #highaltitude. [20:14] no [20:15] Can you take the audio from the PI from the balloon to a W10 computer, because I run dl-fldigi on that computer. [20:16] there's rtl-tcp that can forward the data over a network [20:16] better just put the rtl-stick in the computer [20:16] or what betrik said :) [20:16] and sdrsharp supports that too, but I don't know how well it really works in practice [20:17] JohanM: you are scanning for wx weather sonders ? [20:17] (I *think*) [20:17] Nick change: SA6BSS-4 -> SA6BSS-Mike [20:18] Ok thanks for the sugestion, will take a look at it also. But like to find out first what I can do with this set-up.

ZZZzzz& [20:19] IIRC the band filters helps a lot, to keep out other signals, the rtlsdr by itself has a wideband input and limited resolution [20:19] WX and amateur ballooning both are ok for me on this moment. Because I like to update my performance of the station would like to see signals so I can see that mu changes will work. [20:21] Ok found IIRC band filter via google, going to read that and I think it will help. [20:22] Also am involved in SATNOGS project and also need there a filter for UHF. [20:22] got a rs41 this morning, long time since last :) [20:22] https://imgur.com/w3bLjAn [20:23] JohanM: I think we used this https://store.uputronics.com/index.php?route=product/product&product_id=53 [20:23] (y) Good work Mike. [20:23] tnx :) fun fun before work started [20:25] Looks good Bertrik, but I need to be carrefully with a LNA because I have a inband TX low power very close to my house who is 24/7 on air. [20:26] It is not legal and we agree that they switch of when they not use it. But they forget it often. =( [20:31] JohanM (4da58954@77-165-137-84.fixed.kpn.net) left #highaltitude.
