It sends an update every second I think. The web page updates continuously. Not sure which browser you're using, but try using another browser to see if that's not stopping the automatic refresh.

Duhhhhhh. why didn't I think of that. will let ya know. Was using wincrap8. Wish there was an easier way to test different db setting. having to re-write fr24.sh over and over is a pain. so far 29.7db is the best signal but still doesn't give me the a/c numbers the wincrap rtl1090 does. have to rethink this and see where I'm going wrong. auto gain should work but it gives me no signal but half decent on the cheat antenna. I'm at a loss.Originally posted by Jayant View PostComment

Idea: put your start-up script in a notepad file, change that for the different gain settings, then copy it once modified and right click paste into PuTTY.
In so far the antenna... that one has me stumped. You don't perhaps have your 1090 antenna close to any other electronic thing, and its picking up spurious noise, and with the gain setting, it overwhelms the usefull signal? Say like sharing the mast with some other transmitting antenna or some form of EM interference? Just my 1c thought (sharing your desperation to get it working!)Comment

Yep what a dumb ass I am. Refreshes continuously in CHROME. Did I mention how much I hate WinCrap8. Not sure why I'm even bothering because it's been nothing but crap since install date. Have 6 computers here from this to two win7's , Vista, XP and even one still running Millennium and working. Am tired. been up 36=hours working on this and other stuff.

I edit it in the putty session using nano (just remember it's a console app, so you have to use arrow keys to change the cursor position in the file), or for big edits use notepad or crimson editor on the PC.Originally posted by andyk1 View Post
Hints:
When you start putty.exe, before you select what node you are connecting to
- look in the left "Category" pane select window > colours > select "Use System Colours" checkbox
- now select 'Session' in the left pane, click default settings and save
... now you can actually read the text in the putty window.
When using putty - just select text with the mouse to copy it (no other keys, etc), to paste move the cursor to the insertion point with the arrow keys then right click (again, no other keys).
Copy & paste in putty is counter intuitive to windows users - and is an annoyance, but it does work.Last edited by peterhr; 2013-09-24, 07:54.Comment

For those wanting to use a Pi with from a 12v battery + solar panel ... interesting article here https://sites.google.com/site/vectra...ts/ads-b-raspi (though I'd still use something like the voltage regulator I used for POE since it powers via the Micro USB socket and doesn't bypass the electronic fuse on the Pi).Comment

Sorry, Meant to thank you not Peter on this one But thank you both for the help.Originally posted by scarymonkey View PostComment

Wow. Just spent the last 6-7 hours writing up how I fixed my Pi to work and make a noobs version of peters directions and it never posted. Does anyone know the word "frustrating"Last edited by andyk1; 2013-09-25, 08:13.Comment

Ya I had already done that before thanks. I read part of putty in the past so. Thanks again.Comment

Have my site up and working again. Better. Not what it was working on RTL1090 in Windows Hate but better. Here's my fr24.sh file to look at. Can't get my lat and lon to stick to my location. not sure wtf.
#!/bin/bash
killall fr24feed_arm-le_233s
killall dump1090
cd /home/pi/dump1090
./dump1090 --net --net-sbs-port 30003 --quiet --gain 43.9 --freq 1089930000 --lat 35.50 --lon -97.33 > /dev/null &
cd ~
export FR24AUTHIP=83.140.247.20
./fr24feed_arm-le_233s --fr24key=d7fd65a5b******** > /tmp/fr24feed.log &
Stripped comments to make it easier to read.
Took off my main (tall) antenna amplifier and power injection. Amp was at mid mast so wasn't easy to get to. It made a slight difference better with it on. Checked for a short in the antenna with a multimeter, there was none. tweaked gain to optimum for my dongle. Auto gain -100 and enable-agc don't work for me my tuner was off my 70mhz according to SDRSharpe.exe waterfall Actually all my dongles (I have 4) to varying degrees so I tweaked it which seemed to help a bit as you can see by the --freq 1089930000. Not sure what the Freq spread is in dump1090.
Frustrated the large write up describing my problem, how I fixed it with all your help. step by step noob version installation, setup, links, pictures and the troubleshooting I did... didn't post.
Oh before I forget. I noticed on the windows rtl1090.exe version B:102 that with both Tuner AGC and RTL AGC with the tall antenna was the optimum setting. With the cheap dongle supplied antenna optimum was with RTL AGC turned off. Strange but that's what worked better. Can't find info on what dump1090 uses, Tuner AGC or RTL AGC if it even applies.

Great to see you up and running Andy! Blood, sweat and tears are worth the reward seeing those AC above you!Comment

Thanks HermanZA. Ya I wasted enough time on this project to quit on it now. Need to find the cause of my signal loss in the RPi from the Windows Hate version.Originally posted by HermanZA View PostComment

It will still want some time from you!
You welcome to mail some of those pics to me at: herman -at- eons.co.za Would like to see what you have up there.Comment

Moved the Rpi back down to a 1 amp psu since it doesn't need it. Running it with just the rtl dongle and wifi so.
One thing I just noticed was the led on the rtl dongle flickers from time to time which I haven't noticed on the windows usb port. Need to check that out
