Re: RTL-820T2 IF filters / ISR reception

Why do you want to change the hardware IF?

You can just tune to 500 MHz in any receiver software like SDR#, and detect it there.

Re: SDR# no device selected

I think it was mostly likely that you didn't run install-rtlsdr.bat. Everytime you reinstall the software you need to run this to download the RTL-SDR drivers. They aren't included in the default SDR# package due to software licencing reasons.

Re: FM Radio reception

Did you turn up the gain? Also, reception will be highly dependent on your antenna and if you can get it outside and up high.

Re: if not HackRF, a compatible model?

If you're just using it to see signals you're transmitting locally, the HackRF should be more than good enough. It's only when you get into high performance receiving, like DXers who try to receive far away signals as a sport that you need the higher end SDRs. Or if you're getting into more cutting ...

Re: SDR# no device selected

Can you try other USB ports? Or another PC? If it's not working on another PC maybe it failed.

Re: Buzzing but no AM signal

I'd recommend turning off RTL AGC first.

Those spikes are most likely noise from nearby electronics, those aren't actually airband signals.

If you haven't already, get your antenna outside, and with a good video towards the airport. That should help.

Re: SDR# no boot.

No errors? Maybe a virus corrupting files?

Try redownloading it and starting from scratch.

Re: if not HackRF, a compatible model?

It really depends what you're looking to use your SDR for. Random RF experiments, DXing, transmitting? The HackRF has wide bandwidth, can TX but is only an okay receiver. It's a good multipurpose tool that can do it all, but not great at any one thing. So it's more for general experimentation. Somet...

Re: Unable to Direct Sample from RTL_TCP with Version 3 Dongle

Actually I just remembered that Keenerds drivers does not support direct sampling on rtl_tcp for some reason.

Please look on the V3 users guide at www.rtl-sdr.com/V3, and look for the heading "Modified rtl_tcp for direct sampling". Compile and use those drivers and you'll get the -D flag for rtl_tcp.

Re: dongle v3 : Direct Sampling HF Mode

Nice, looks like that will work. Looking forward to seeing your results with direct sampling.
