What hardware is the SDR?

Is that a one piece computer addition with its own receiver or does it interface with a larger receiver and go between the radio and the computer?

I had to take down my antennas to sell my house, but I might like something that doesn't require a full size receiver until I move.

I meant to use an antenna at my location, not just listening to other people's locations.

What a radio receives at one location is different than what one receives at another location.

Over the Internet you hear what somebody else's radio is receiving.

That isn't bad and is interesting, but if the receiver for a computer is cheaper than a full size receiver, it might be a cheaper way to listen to locally.

Probably not enough for what you want to do, but my little handheld Baofeng is freakin amazing.

Can you hook up an external antenna to it?

Here's a collection of open source software for radio use:

If I just search the radio software available for Linux i get a good sized list.

I can't use all of it, but some might be helpful.

So far i just use some antenna design software.

The Icom IC-7200 is being clear out on sale right now, but it is an older design.

It has some digital and computer interface functions, but I think a newer design might have more.

The price is way down though, so I think I might try it.

Listening to somebody's SDR saves me from having to spend money on hardware to listen to the radio before I move.

I wasn't planning on buying any new gear until after I move, but the IC-7200 looks to be at the end of production and the price is tempting.

I like to listen to Europe at sunrise and to the west at sundown.

There is a free to use SDR in Canada that is interesting to listen to.

Got a ham buddy whose been designing, building and selling these SDR's and software for almost a decade now. He sent me his current SDR gadget awhile back and walked me through the installation. In the end, I just couldn't get into using a mouse to browse the spectrum, seemed too sterile for me. I guess I enjoy analog better along with the unknown.

IT's a Kiwisdr. It's self contained , and is powered by a Beagle .

The only connections are:

5 VDC
GPS antenna
HF antenna
Ethernet Cable.

By the way, using a plug in and the fact that the Kiwis are time synched (they all come with a GPS antenna) and location known (via the GPS) you can triangulate on a given signal coming from anywhere in the world and determine its location.

I noticed they had GPS, but wasn't sure how it worked.

I figured it was for direction, but yeah, location makes sense.

I managed NOT to kill it today, even with 1050 watts out CW on 40 and 20, aimed at the SDR antenna during CQ CW WWDX contest.

Bet I showed up bright on the waterfall chart during that (forgot to look)
