Problems with feeder statistics and data sharing

[JohnnyBravo]

The stats look unchanged again today so I've logged a support ticket.

I've also emailed them, asking about stats and F- and T- feeders.

Well spotted. I've just checked the whole of Portugal and all the feeds are F. Something weird is going on.

I've checked mine, F & T Stations are in working.

I do not wish to add to the controversy about statistics, but I have also noted something strange. In the past when on the main Flightradar dsplay, dislpaying the map and aircraft, clicking on any aircraft would show (in my area at least) a fair mix of 'F-' and 'T-' radars, now they all seem to be mainly 'F-' radars and rarely a 'T-' radar. Is it just my obversation?

Perhaps they have changed their feedin priority to only supplied equipment(F-)?

Nope, I’ve noticed the same!

Most likely yes. If you already have dump1090-fa or dump1090-mutabity ver 1.15, and choose Receiver=DVBT, them fr24feed will install dump10o0-mutability v1.14, causing conflict between two versions of dump1090, and result in malfuntion.

Hey abcd567, I eventually did a fresh install of my Dump1090mut and FR24feed. Using your advice of how to set up FR24 to ensure it also doesn't install itself a version of Dump, my system now displays the adsbproject range graphs etc

it seems to be frozen. Maybe they're working on the database?

Nah, they've gone home for the weekend!

I'd hazard a guess that the stats have got stuck for the last couple of days. I can't see any up/down arrows on the FR stats page and Patrick's excellent page also shows identical stats for 14th and 15th.

so they'd be sending out 10,000+ emails daily!

Which is a tiny amount of email traffic.

Other systems with large numbers of participants manage to do this without any problem. https://atlas.ripe.net is one example that notifies any of 10,000+ probes when they are disconnected for a user-configurable time.

Frankly it's surprising that they've taken so long to fix the problem and offered so little information to participants. One wonders if they have some sort of serious organisational issue such as finding a person who understands their system. Maybe they outsourced their server development and have no internal competence?

Whatever the cause, it's a heck of a long time for an online service to be broken.

I have one underway at the moment, using (don't laugh.. Water pipe, Bamboo and 18gauge plated copper wire. (Characteristic impedance approx 45.5 ohms so a 50ohm Feeder should be fine).

(1) This looks great. What velocity factor you took for bamboo insulation you slipped over copper wires?
(2) Discussion about antennas is off-topic for this thread. Let us continue antenna discussion in relevant thread:

best antenna

The "best antenna" thread was started in November 2011, and due to very active discussions, has by now grown to 273 pages

One more thing to do: as you have vast ham experience, try to make different types of 1090Mhz DIY antennas. It is a good pass time and challenging job to make a high gain collinear antenna (wire collinear & coaxial collinear).

if T-Feeds can 'specify' that's news to me.

I didn't say T-Feeds can specify. That's the point, T-Feeds aren't advised if the feed is offline.

And I was responding to your assertion that alerting T-Feeds would generate 10,000 emails daily.
