Questions and Answers

I received lots of questions regarding my new book, and about RTL-SDR in general.

"Why the book is not about RTL-SDR, why did I got a Raspberry Pi 3 book?"

Amazon delivered the wrong book file - pre-order readers got the Pi 3 book, which came out on the same day.
New book orders are not affected.

Pre-order customers can get the right book file with the following steps:
1) Go to your Amazon website, log in, then click "Manage your Content and Devices".
This will be middle of the list, one down from the divider line.

2) When your books load, please click on the three dots next to the title name, then Select Update.

This should update the book file to the proper RTL-SDR book.

If you run into the slightest difficulty, please email me and I'll do my best to sort out any issues.

"Why no Tetra / P25 decoding software manual?"

Because I will not provide information on how to listen to police or government communications. Full stop. Ever. 
In the wrong hands, knowledge is a weapon, which could be used against innocent people. Brussels, Paris, London, Madrid, New York, the list is sadly too long.
I will not contribute to that list, directly or implicitly.
Listening to Tetra is not a radio challenge, it's an encryption and software setup challenge.
I love radio, and enjoy the rush when a weak signal comes in after days, sometimes weeks of tinkering, or seeing that measured signal floor dropped a few decibels. 
That's what the book is all about: getting the best performance.

"Why Nooelec / / Adam's products?"

'Cause they are the best, and got good customer service.
Make no mistake, I will review any product from any manufacturer, and include in the book as long as I trust and believe in it.

"I want more details on <insert what you want here> !!!"

Sure, send me an email, or comment here, or on the Amazon pages, and I will include your request in the Third Edition.
If you don't tell me, I won't know, yeah?

"Some of the mods you suggest are way too much for a $10 dongle!!"

Come on, you want monkeys, you gotta have bananas.
Methods will work with an SDRPlay or a three-grand USRP, physics is the same.
Beginner level mods, such as PCB alteration and basic noise suppression measures cost nothing, and take a few minutes.
Intermediate level mods will take performance further, and may cost a few dollars.
Advanced level mods take a lot of effort for minuscule gains.

If you want the best performance, it will take time, gear and $$$.
In the image above, I'm using four small heatsinks (only two visible as rest in insulated box I did not rip apart for the image), two PSUs with two Peltiers, oil cooling and basic antenna connectors, it's a testing setup only.
Whether you wish to walk down the ultimate alley it's up to you, if so, the information is in the book.
