        Very strong local interference or there's something wrong
        - did you add anything ... different coaxial cable
        - earth loop

          i will put my money on dongle connection and/or antenna

          p.s.
          it's wery hard to follow your problem when you write in many topics

            no earth loop but i guess the interference is from my VHF antenna because it is in height i place collinear antenna beside it so this evening i moved the antenna to other building there is no interference but due to low height my range decreased but signal was good

              • without good pigtail, good coax, and precisely made/positioned antenna you will never solve problem.
                this is really sensitive "sport". I saw your "pigtail" picture. Not going to work. Pigtail is 3$ expence and makes miracles.
                SDR# and "waterfalls" are not signal quality tool.

                  Since Mike cannot answer it seems, i will have to ask the question here, as i like a challenge.
                  What would a totally crazy coverage means distance wise you think?

                  This weekend or next weekend i am going to do some tower testing.
                  I have a small laptop+rtlsdr mini+adsb#+fr24feed running. I will make virtual radar server screenshots to keep record of max distance.

                  http://x264.nl/dump/ads-b-antenna-gr...ane-proper.jpg will be used as antenna.


                  My current record at about 40 meter height:

                  With the FR24 receiver according to the stats page, 2014-03-17:

                  • Not unusual, my hight is shown as 164.5m [AMSL]
                    And the antennae is on the roof just above the tv antennae, I am in quite a high area with good coverage of Farnborough, Gatwick and Heathrow (EGLF, EGLL, EGKK) and often get ground coverage at all 3 (not often at EGKK but quite often at the other 2)
                    I see max distance of 300+ nm 2-3 times per week.

                        Which antenna are you using and your configuration?

                            So it will this upcoming weekend. If tests show good progress i will submit another receiver request or a move my current receiver request.
                            Or leave it as it is, whatever the FR24 peeps prefer!

                            • Scheduled down times

                              Hi all,

                              This weekend weather forecast are good thus I plan to climb on my roof and reorganize my antennas a little bit.
                              This will lead in F-LFST2 and T-LFST3 to be down for a couple of hours on Saturday.
                              Whereas T-LFST3 is not a problem, F-LFST2 is an issue since it is powered by a FR24 receiver.

                              I don't know if there is a way to signal scheduled down times to FR24 to avoid getting an automated alert because the receiver is down. Maybe a thread dedicated to this would help.

                              How did the other FR24 receivers hosts handle such scheduled down times ?
                              F-LFST2
