    got a reply, no old scopes, they recently switched buildings so I was just a bit too late :p. But Ill probably be allowed to do some tests/measurements in the antenna lab of the EE-Antenna department of the University :).

    Goodluck, you can do it ;) Also, Im almost readyto release my new version instsller script. (have been rewriting it and even madeit so thatit dynamically grabs code parts based on what each script needs, somewhat comparable to including files.

    Lots of posts, makes me eager to experiment as well.. Also send an old teacher/lab supervisor from electrical engineering a mail to ask if they have any old oscilloscopes laying around that I might be able to borrow/buy for a small price so I can do some more detailed testing :D (especially for...

    Actually, i think that it has only 2.3dB insertion loss/attenuation at 1090Mhz. not sure about 970 -> 1075 and 1105 -> 1150 MHz though ETA: see this frequency response graph:

    Hmm, I thought I had posted the solution, but apparently I didn't :oops:. What I had to do was to remove all the comments between the different parts. (IIRC there was a white-line, comment line and agian white line before each of the line numbers mentioned in your errors.) Make the code such...

    Do note that I had to change all your MINNAN and MAXNAN commands to the normal MIN and MAX because otherwise I would get errors, and I had to do the same for Jepolch to get it to work for him as well. Not sure how this would impact the zero instead of NaN thing.

    IIRC, @caius mentioned that it takes some time before the trailing average is shown, (as you need the data going back far enough to generate the average) with the original pi rrd was running long enough before you added the trailing average graph to have enough data so it created it immediately...

    amplifier showing its worth, just picked up aircraft at 186.2 NM (344 KM) from eindhoven with my little spider :D

    I'll look into it. I'm making a list of all the little things/bugs/cleanups so I can combine them and make a lot of changes for the coming version/release :D. About the not showing exact location in dump1090-mutab config. As far as I know that shouldn't really matter. Internally it calcualtes...

    Some nice stats with the amplifier: Before: (~€60 ebay antenna) Average positions: 111K Average planes: 3368 Currently: (one of the earlier spiders with amp) Average positions: 139K (roughly 25% increase) Average planes: 3760 (roughly 12% increase) Range/radar plot with ebay antenna (peak...

    Hmm, it seems like this has to do with there the location/configuration files are located for ubuntu with respect to the ones for raspbian. I'll need some more time to get it propperly fixed for ubuntu :/.
