So I’ve had my system up n running for 32 days and have slowly been improving it. So far, for what it is, I am pretty happy with my results. I am feeding FA, FR24, Plane Finder (love their 3D polar plot!) and Radarbox24.
I have been running a headless RPi3 with an el-cheapo DVB-T R820T dongle that I bought from ebay, connected to a 12 segment collinear that I made which is on top of a 5.8m mast. No amp, no filters. My max range has been 235Nm and I average around 108Nm, so pretty happy with that given my location and basic set up.
My pi zero W arrived yesterday, this was to permanently replace my RPi3 so that I could use it for other projects. I copied the image across and got it all fired up and left it overnight. By this morning it was obvious that my range had dropped significantly.
Although the zero is working a bit harder (40-80%) I don’t think it is a ‘grunt’ problem. I am suspecting that the micro USB adapter is getting some interference from the power cable being located right next to it. Either that or the dongle I am using has a problem running through a USB adapter as I did have a similar problem when I tried a much longer extender (different one) with my RPi3.
Currently I am going to try a completely fresh install of everything rather than an image of initial setup from from RPi3, though it might be a couple of days before I get the chance to try this.
Has anyone had similar or have any suggestions?
