Recently I was given an SDR to test from SDRPlay in the UK. I specifically wanted to check out the FM on this unit because being able to see 8mhz of spectrum during a skip or tropo opening, and being able to record it and play it back later, would be a great aid to the FM DX hobby (the Elad FDM-S2 just does 6mhz).
I tried it out for two weeks and then bought it from them. I wrote a review of their RSP (SDR) and posted it here. Check it out.
This unit sells for half the price of the Elad FDS-S2 and should be affordable to many more DXers. I think it's a keeper.
