Re: The choke used for the switching power supply on the rtl

It looks like his mod reduces the switching noise which seems to always show up at around 1 MHz. I don't think it makes much difference anywhere else or to the noise floor though. There was another Japanese experimenter who actually removed the switching supply in favour on a linear supply. See http...

Re: The Chinese and translatetion

His site is good and the language he writes in is actually Japanese. Unfortunately, Asian languages don't machine translate well into English. I don't know if he can speak passable English, but i'd guess not.

Re: Weird peak on sdrsharp

That's normal and part of an effect of the design of the dongle. You can get rid of it by enabling "Correct IQ".

Re: Stability Issue using Nooelec Up Converter

First you could check if its the upconverter or dongle by testing the dongle out on a VHF signal. I would say that if the upconverter frequency drift is a big problem you should contact them and ask for a replacement crystal. The dongle does have a oscillator and it is known to drift. The dongle and...

Re: install.bat won't run

Hmmm I googled "windows xp won't run batch files" and it seems to be a common problem. It could be that your system has associated .bat files with something else. There's a fix available here http://www.dougknox.com/xp/file_assoc.htm. If that doesn't work i'd suggest asking in the SDRsharp Yahoo! ma...

Re: install.bat won't run

Are you sure you've unzipped the files and aren't running it from inside the zip file? If you have unzipped it correctly you can see what the error message says if you run install.bat from the command line. Open command prompt from the start menu and then use "cd" to browse to the directory you're s...

Re: sdr and high CPU usage

An old celeron like that might not be powerful enough for SDR. Generally at least a dual core processor is recommended. I assume you used SDR#. You could try to remove the waterfall display, or reduce its resolution. Also reduce the sample rate to something like 1Msps or less. Some people also repor...

Re: rtl-sdr/tcp

Any reason as to why you are using RTL/TCP? RTL/TCP is for when you want to run the dongle remotely and send data over TCP.

For normal use with the dongle plugged directly into your PC you should select RTL-SDR/USB.

Re: ATSC compatible dongle? and oscilloscope question

I still havn't seen any project where the RTL-SDR has been used as a true oscillioscope.

The Red Pitya is probably the thing you need if you want a SDR oscillioscope at the moment.
