It is what I will refer to as a "proper" SDR i.e. a = direct sampling =0A digital down conversion SDR.
=0A
It covers = 100kHz to 30MHz, has a maximum bandwidth of 1.25MHz and has a =0A LAN inte= rface for remote access.
=0A
The best bit is that it costs just = over =C2=A3200 inc shipping and VAT.

Hi Mal

The whole reason these things are getting so much attent= ion is the =0A price and the fact they are independent of a sound card o= r A/D =0A converter. They are not really suitable for or give = any advantage on LF =0A because you need an up converter in front. A Sof= trock SDR with a good sound =0A card will out perform these sticks at MF= /LF.IMHO I don't think its =0A worth persuing to be honest. However= I think with the DVB-T sticks people =0A have been opening them up to l= ook at the SMT chip marking if not sure. It =0A looks like they don't er= ase the markings like some well known LF TX suppiers =0A do. Oh and the = software plug-ins are only for the RTL2832 chipset.
