Been Kinda out of any loop on this   

BUT

if what I read,, if I connect a TV tuner usb dangle witht he correct chip
set
it will cover MF to HF using  an appropriate program. I use HDSDR with my
SDR IQ
which I like for general reception. So by using the proper chip set HDSDR
will run that TV dangle as a HF radio

??

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 Ł200 inc shipping and VAT.

You can find more details here

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.
