You didn't say what other testing you have done. I would recommend installing rtl_433 and listening on 433.92 MHz, 315 MHz, 915 MHz if in the US, and some other set if you are in a different ITU/regulatory region. (One of the main rtl_433 contributors is in .de, so the docs should have good hints for Europe (868 MHz?) -- but basically I mean the license-free frequencies.) I hear quite a number of devices that aren't mine. This will let you know if your dongle and toolchain is working. You can also assess frequency stability. The cheap dongles are cheap! I have two of those and one "NESDR SMArTee v2" which has a TCXO. Your log shows 868 MHz. That seems like EU, and I wonder if you are sure that your ISS is the EU version. They are on 915 in the US. I also hear people say that the dongle should be remoted from the RPI via a USB cable, to reduce noise. Take the pi out to 10 feet away from the ISS, line of sight, and try it there. -- You received this message because you are subscribed to the Google Groups "weewx-development" group.
