Re: DSDPlus not decoding

DSD+ has an audio waveform monitor screen, does that show any movement, or is it flat?

Put up some screenshots of your setup if you can too.

Re: Driver for "blue" RTL_SDR R820T2 ?

Please follow our install guide at www.rtl-sdr.com/qsg.

Nothing against those box type RTL-SDRs as they do work okay...but they do seem to have a decently higher than normal fault rate, so a hardware fault isn't out of the question.

Re: installing SDR SHARP

If you're using an RSP with SDR#, note that the new versions will not work with it.

To be safe i'd make a backup of your current folder and keep it safe.

Also, if you want to try the new version, extra the files into a NEW folder, and keep the original safe.

Re: need help about RTL2832U

Yes but since it works in HF with direct sampling mode, i'd recommend using a bandpass filter for radio jove frequencies.

Re: Stock dipole antenna kit orientation

The center element is the smaller wire with the plastic on it. The ground element is the wire that's all braid.

In reality the orientation doesn't really matter too much.

Re: SDR for Frequency Deviation

Why can't you just connect the RF output to an attenuator, then into the SDR?

Re: Filter and lna

To build on alanzfq's reply antenna -> Lna ->bandstop filter -> dongle ->USB P. Is the best, assuming you don't have very strong signals in your area that could overload the LNA. antenna ->bandstop filter -> Lna ->dongle ->USB PC. This should be used if you find that the LNA is overloading. The SPF5...

Re: FM broadcast mirrored to different bands - fault?

This behavior is expected with the lost cost 8-bit RTL-SDR dongles. Basically very strong signals will overload the dongle, and this results in those strong signals being imaged to other frequencies. The possible solutions are: 1) Lower the gain 2) Use an attenuator 3) Use an tuned for the frequency...

Re: Hotter SDR?

Is the SDR simply in a warmer place, or maybe now lying on a carpet/some insulating material? One other thought is that some RTL2832U chips do have a bit of a fault with their DCDC regulators which can cause them to heat up more than normal, and draw more current. Maybe the USB cable voltage drop is...
