Here’s a collection of SDR videos for you to chew on – without a lot of time or money – you can get started in Software Defined Radio – and you can fart around with it on just a few bucks – or – you can spend to your hearts content – and you can listen to stuff besides the propaganda you are being spoon fed . . .
This next one is 2 years old – and the technology is constantly improving – but it will give you a view of what’s out there . . .
And you already have a computer – right? You can even use your smart phone . . .
These last three – if you’re still here – are from Ask Dave – if you have questions about “radio” – chances are Dave has already answered them .
I actually have 2 or 3 of the little dongles floating around hear – and I may have given 1 or 2 away – or not – but . . .
My two primary SDR’s are the DX-Patrol MK4 SDR Receiver from DXEngineering and the Airspy HF + Discovery from from Nevada Radio / UK – Why 2 you ask? The DX-Patrol is way cool – GREAT high frequency coverage – but – it only tunes down to 100 khz – the Airspy only tunes up to 31 khz – but – tunes down to .5 khz ( that’s 1/2 khz! ) – way down in the basement – submarine comm link basement levels – there is a whole ‘nother world of low – emphasize LOW – frequency traffic out here to listen to – there are a number of forums devoted to that type of traffic.
The other issue(s) with low freqs becomes the antenna – 600 foot plus (1200 foot is better) longwires start to get you there – but they also start to become somewhat directional – though a loop antenna will get you close the efficiency takes a dive below 50 khz . . .
This little post will get you started if you are so inclined – and remember – the cheapy little dongles? – like most other things – you are pretty much getting what you pay for!
Have Fun! – Run the Gun! – and remember – Fish Heads are Cheap!!
