How to run lots of SDR's with remote control
Here, on this website, you will find nothing about connecting to a lot of remote receivers around the world,
This is just my story on how to set up and use remote solutions between a city home and our countryside residence, what in Sweden is called a "torp" (croft, smallholding). Thus DX-Torpet.
And how you could do it yourself -- but Should we still call it DXing?

Hardware

Many years of remote DXing
For several years I happily used older computers to run two, three or more SDR receivers on one PC. All on site, in the summer.
But in winter I needed a remote solution, to avoid the two hour trips to fetch DX recordings. Not that easy, and this is how to do it.

Bottlenecks in high speed data transfer
There are a lot of bottlenecks if you want to transfer a lot of SDR recordnings. Those files are huge. This is what you need to know.

Which computer for which radio?
Modern radio is all about SDR, meaning that the "radio" is more Windows than radio (Mac users is in trouble, Linux users are fine with necessary programming skills).However, which PC to choose is not that straightfoward...
Bjarne Melde on ArcticDX: "Don't buy a Windows PC running on Snapdragon for use with SDRs unless you have checked hardware compatibility."

Auto restart PC after power failure
After a power failure, or any Windows mess up, it is very nice to have all your computers and SDR's restart automatically. It can be done, like this.

What SDR is using what on my computer??
Running more than one SDR on any computer can be frustrating... before getting it to work properly.
What is using what, and how to find bottlenecks, one good start is already available:
In Window's device manage select "View --> Devices by Connection". You will see the complete hierarchy and which root hub you are connected to if you have more than one.
If you only have one root hub you're not able to run many SDR´s with huge bandwidths, say 10 MHz. Simple arithmetic is against you if you try to work off a single controller, aka root hub, due to USB limitations. Your motherboard documentation may tell you if you actually have multiple root hubs or not.
So while USB is easy to use, its capacity is limited. To learn more: www.elprocus.com/usb-protocol/

Software

SDR Console -- a must
This is a first class SDR tool. It has everything you need to get the most out of almost any SDR receiver. The setup for recording I find somewhat awkward, but its filters and audio quality makes it a superb play back machine for any recorded IQ file.

HDSDR -- a good start
Good old HDSDR is, probably, the best way to start with SDR receivers. It is fairly easy to use, covers just about every SDR with plenty of extensions and has tne best recorder, which is why I use it every day.

SDR# -- not that sharp for everybody
SDR# is the perfect companion for Airspy receivers. Work great with others too, but not the most user friendly software.
Preamp on an Airspy? Forget it!

Jaguar -- a tough beast to tame
Some highly devoted MW DXers use Jaguar, a specialized software for the Perseus SDR. A great application, but it is also a difficult beast to tame -- not least as the Jaguar's master, Ilpo Parviainen, insists on changing a lot of things constantly. So if you don't have a Perseus (first version) and are not entirely into MW DXing, this is not for you.

Best MW recorder for Perseus SDR
With minimized resource usage, auto restart after power failures, running two Perseus on one PC, and antenna switching, this free KIT recorder is the best MW recorder ever. Reccordings can played back in Jaguar, HDSDR and SDRConsole.

Jaguar on none-Perseus receivers
Jaguar is as closely integrated with the Perseus SDR as you can ever imagine. But you can use recordings from other SDR´s, mainly those from SDRplay. This is how you do that.

Altering timestamp In Perseus IQ .WAV files
Occasionally someone has the need to change the time of the recording, possibly because their computer clock was off when the recording was made. This can be easily done if you don't mind some byte twiddling in a hex editor. This is how you do that.
