Troubleshooting Help • Driver issue

I would like to use an RTL-SDR Blog V3 with HDSDR on my PC running WinXP, but I see that there is not a Zadig driver that would work with that combination. Is there a work-around to this, or will I have to get a more modern PC?

Tnx & 73, Bruce, VE3EAR

I don’t suppose this software is available for Mac OS?

“If you buy cheap, you buy twice” – German (not Chinese!) proverb.

By the way: one still needs to pay taxes on importing, even as a private person. And ecologically and socially chinese manufactoring and worldwide transport is questionable.

Comment on SDRSharp Users Guide by Art Delibert

I’m playing with a new Airspy HF+ Discovery and SDR#. Question: Is there a notch filter option somewhere in this system? That is, if two AM shortwave stations are close to one another, such that their carriers are causing a whistle, is there a way to remove either the carrier of the unwanted station in the IF passband, or the audio whistle frequency in the audio passband? This is a common feature on high-end shortwave radios. Thanks.

KerberosSDR • Re: Feature requests / development ideas

Hello again,

I would like to propose that getting the raw coherent data will be the first improvement to be done. I suppose that it will help the open source community to start developing their own ideas.

Perhaps could it be released a tool like rtl_sdr or hackrf_transfer to export the data to a file? Then the user will do whatever he wants with it.

Thank you.

Comment on GPS Tracking with a modified TCXO RTL-SDR by Conundrum

Also found that a blue LED connected in reverse between “Hot” end and Gnd will work to some extent. Halfway house if you can’t obtain a modded dongle but it worked for a while at least.
You might have to try a few diodes as their reverse capacitance can be variable, for me the first one out of the strip worked but capacitance is quite critical. If you overdo it then the dongle will stop working completely.

Yes this is correct. Folks found that changing it too much resulted in USB failure.
I also found that to some extent you can simply put a blue reverse connected SMD LED of a specific type on the high end of the crystal and this will also compensate a little for drift.

“Reknown for its quality components and workmanship…lol.”
You are probably speaking for you, workmanship in China is better than what you will ever be able to provide (if you ever produced anything, which i doubt), not to mention the average IQ in China is far superior than yours and most average IQ of western countries. For you information the 21st century is Chinese, no longer American, and by the way the new silicon valley is ShenZhen.
