In previous part<\/a> i wrote about LifeViev DVB-T usb stick based on RTL2832U and Fitipower FC0013 tuner.
\nIn spite of information on http:\/\/sdr.osmocom.org\/trac\/wiki\/rtl-sdr<\/a> site, FC0013 in this stick doesn’t go up to 1.1GHz :-(. In fact, from my experience it could do up to somewhere little above 900MHz.<\/p>\n

New stick with R820T tuner<\/h1>\n

As I want to measure also my FPV equipment, with TX running at 1.2GHz, I bought another DVB-T usb stick based on new tuner: Rafael Micro R820T.
\nIt’s very popular and cheap on eBay (about $10), but it haven’t particular name.<\/p>\n

That’s my ‘no name’ stick:
\n\"RTL2832U<\/a><\/p>\n

And of course inside:
\n\"RTL2832U<\/a><\/p>\n

As I wrote above, Lifeview with FC0013 can’t measure my video TX at 1.010GHz (but this should be within it’s range):
\n\"Video<\/a><\/p>\n

But the same on dvb-t stick with R820T looks fine:
\n\"Video<\/a><\/p>\n

SDR#<\/h1>\n

In previous part I promised to make some effort and test also SDR#<\/a> (aka SDRsharp) software.
\nCompiling and installing Mono<\/a> appeared quite easy.
\nInstalling PortAudio library also went flawlessly.
\nIn howto<\/a> there are described 2 ways of installing SDR#: using MonoDevelop and from command line. First option was a ‘dependency disaster’ – so I gave up. Then I tried second option. It didn’t work either \ud83d\ude41
\nAfter some experiments, reading manuals it turned out that default option tried to compile native code for my 64bit system and this part of SDR# is simply broken.
\nWhen I forced to compile to 32bit binary (luckily I have multilib installed), it finished without error.<\/p>\n

Magic compile command:<\/p>\n

xbuild \/t:Rebuild \/p:Configuration=Release \/p:Platform=x86 SDRSharp.sln<\/div><\/div>\n

Results:
\n\"SDR#<\/a><\/p>\n

After some clicking, double clicking, dragging etc. I could also share my impressions about SDR#.<\/p>\n

Pros:<\/p>\n
