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 the bette...

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 ...

Try setting it to Zero-IF or LowIF and set the gain to about 50%, see what happens.

Re: Sample rate and buffering samples retrieved

You're divider is off, as you can't simply divide by 11. Bit/samples/bytes etc work with a power of 2. So it's always a multitude of 2^x, that works the same when decimate. It decimates in the same power of 2, like 0, 2, 4, 8, 16, 32 and 64. All other decimates result it illegal call and turn off de...
