Re: Best antenna no good signals?

My mission in life is to convince the world that end fed wires are absolutely horrible and that anyone who has one who can find a second remote mounting point to create any shape or size of horizontal delta should build one immediately ;-) Same here. But they are not End-Fed, just sold as such. As ...

Re: Sample rate and buffering samples retrieved

Weird is that your link shows a comment like this: For example, if you double the sample rate, an equivalent filter will require four times as many operations to implement. This is because both amount of data (per second) and the length of the filter increase by two, so convolution goes up by four. ...

Re: Best antenna no good signals?

An antenna depends on the frequencies you want to receive. There is no simple solution to receive all bands. For HF it means a very long wire and some counter point, then it will work.

Re: Parting thoughts

Nobody is forced to read other people's replies. You can choose to simply ignore them and move on. On every forum in the world there will be people that post stuff that other don't like. Walk the dog, ignore it and be happy is my way. In the end you are just reading a screen and you do not know who ...

Re: New Sdrplay and antenna creation

What you have "build" is an antenna with grounding at the end. It's not uncommon and it does work. Basically you probably made this beverage without knowing: http://www.teknokekko.fi/dx/mwdx/beverage.jpg Funny thing is, the longer the wire is below 80m (especially the very low bands) often...

Re: rsp_tcp setup with websdr

Where is the link to your websdr? I would love to have a look at it.

Also the chatbox has a problem with spammer, I made a spam-filter for it, if you want it, let me know then I send you the code.

Trust me, the websdr-spammer will find you as soon as you publish your receiver.

Re: rsp_tcp setup with websdr

You need some different settings then I use. First of all, you need to compile the rsp_tcp and call it as such. Then call it like this from the websdr.cfg: ####################################################### # RSP1A 0-2 ####################################################### band RSP1A 0-2MHz de...

Re: New Sdrplay and antenna creation

Hi Ken, You do not need to ground the antenna, it's just one way of doing it. The antenna described in the article is just a wire, as such it doesn't have a counter length. Grounding can provide that but also adding some length of counter-wire or a fence. Grounding can attract lightning and as such ...
