    I noticed that most of people in UK started to use e-cigarettes (due to prices).

    These DVB ones last about 2-3 years most of the time. They make a lot of heat. That's why I like the RTL-SDR, they are encased in aluminum with thermal padding. The FA one is really nice because it has a filter and amp built in for 1090, I get 275 miles with a roof top.

    Lately we have been experimenting with thermal transfer tape and $4 heat pipes from China.

    If old stick is broken then any new one should solve problems.

    Here is what the ones we deploy tend to look like and work for years.

    When applying heatsinks .. you need no electrical conductive material.

    Yeah the USB reciever is up and down. It might be overheating, these make so much heat after years of use they can flex and de-solder intermittently.

    Running the script manually to see if it throws errors.

    If you ordered the same one you have they should be -- FlightAware one has a different connector

    Old blue one has MCX, FA blue one has SMA, if you heve something like pigtail MCX-SMA then antenna can be connected easily to new stick.

    In different language, it means the tuner can't tune where it was told to. You'll end up receiving nothing or receiving some other frequency.

    This is bad for reception at that frequency, of course, but it's harmless if you then successfully tune somewhere else, and the driver doesn't print a message on success so you can't tell the current state.

    Most likely the programs you are using are just being a little bit sloppy (e.g. setting the frequency to 0 because they haven't initialized everything yet, or going a little bit outside the supported range).

    I can send you this old blue stick for delivery cost only.
    We are still in EU :D.

    Seems like tuner might have failed or is likely failed .. meaning it can't hold the 1090 mhz and wanders off eventually locking up.

    We haven't started selling SDR, if you really want a FA one or RTL-SDR one with the SMA. I should be able to Amazon you one.

    We are sourcing 26" and 42" antennas that tune both 1090 and 978 better than the FA one. Looks like they are going to be about $45-$50 USD plus shipping.
