Elad S2 Excellent Radio
I have been playing with various SDRs for several years now. I have built small kits, and purchased expensive units. Essentially I have own a good cross section of available SDRs over the years and I can honestly say that the S2 is without any doubt my favourite to date!

The unit is small, doesn't require an external supply outside of the USB, preferable USB3. The band coverage is awesome, and the ability to see a much larger swath of band, as apposed to the standard 192KHz as offered by others in its price class is awesome. Sensitivity, selectivity, dynamic range it has it all and the accompanying software is being upgraded daily by the Elad Team.

Couple the above with the above average customer service that I have received from Elad USA, Barbara in particular, I have no hesitation is recommending this product.

If you are looking for high end performance, at a reasonable price, you have to consider the S2.

Thanks Elad
