Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi all

I'm thinking about acquiring a USB SDR to use for spectrum analysis, ideally up to 3ghz or so, or 5ghz if affordable.

Does anyone have a pet recommendation, ideally with a supplier?

Thanks in advance for your time...

They also did an updated article in Nov 2017, based on a kit from Banggood.

Being based on TV dongles, they are not going to make it to 2Gig.

Here's the kit anyway.

Cheers.

A down converter would get the range higher.

Bit of info here.

Thanks guys

I have ordered an RTL-SDR R820T2 (RTL2832U v3) SDR with Dipole Antenna Kit from a local supplier for $45 including delivery - I didn't think that was a bad deal from a local company. I'll work on a down converter later after I've been through the learning curve with the base unit.

The journey begins...

Thanks again

I too have been researching SDR modules for receiving meteorological weather satellite transmissions around 1700 MHz and so far the best I have tried which is reasonably priced is the Nooelec Extended range model

http://www.nooelec.com/store/sdr/nesdr-smart-xtr-sdr.html

I have one and quite satisfied with the results so far up to about 2200MHz.

Some of the other ones I have tried are rather unreliable above about 1600 MHz, especially when warm.
