Re: High-pass filter characteristics for RTL-SDR.com ADS-B filtered amp?

I don't have the exact numbers on me at the moment, but the 3dB is around roughly 900 MHz, so you should be fine with replacing the SAWs.

Re: Driver issue

Are you sure that you're plugging it into a USB 2.0 port?

Also check in Device Manager if the dongle shows up.

Re: SDR # Set samplerate error

Are you using a USB cable? Sounds like the port/cable is not able to supply enough power to the dongle as the current increases when the start button is pressed.

Try other ports, eliminate bad cables etc.

Re: What to buy from here for Android.

All you need is a USB OTG cable (preferably with external power port), RTL-SDR dongle and a battery pack.

You can install free software like RF Analyzer, or the paid SDR Touch.

Re: What satellites i can work with on 137MHz.

Not really, you might try looking slightly higher up to ~145 MHz for the ISS and amateur radio satellites, and if you're in the right region, up to ~243 Mhz for the milsatcom band and pirates.

Re: Driver issue

There are XP versions for Zadig available on their site https://zadig.akeo.ie/downloads/

They are not supported, but it should work.

Re: RTL-SDRV3 quit

You appear to be loading the RTL-SDR TCP interface. You need to load the USB interface instead.

Re: "external" Bias-T for Antenna?

Just to note we're not promoting that antenna, just posting news about it.

The second one might not be good, as the lower end is specified as 0.01 GHz, which is 10 MHz. The others specify operation down to 1 MHz.

If you have a RTL-SDR V3, try the bias tee on that too. It works fine.

Re: New version of kerberosSDR app

I was running the earlier Android version requiring Android 8.0 or > and had collected a few log files..... I decided to load the later version - now every time I try and open one of the older log files - the Android app crashes. I have not had time to setup and try the newer version of the app and...
