Ok Tracy
 
I have a fair over view of the SDR scene.  Price/cost is relative. I operate at the low end.

Hello Pete
 
If we're talking about low priced SDRs, there is a relatively new kid on the block in the form of the Afedri SDR-Net from Israel.
It is what I will refer to as a "proper" SDR i.e. a direct sampling digital down conversion SDR.
It covers 100kHz to 30MHz, has a maximum bandwidth of 1.25MHz and has a LAN interface for remote access.
The best bit is that it costs just over £200 inc shipping and VAT.
 
You can find more details here
 
 
 
I've no connection other than being a satisfied customer.

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