Amazon UK has a bunch of DTV dongles for under £20. See example below:-

I read about these TV dongles, mentioned a few months ago. But this VHF stuff is uninteresting for me. However, if there are sticks that cover LF and MF, this could be interesting.
So, what is the name of the stick? Link? "Cozy Cave" leads me to that page http://www.calicavycollective.com/2012/04/cozy-cave-from-cozy-cavy.html

UP Convertor ?
 
Pete
 
No need now  , the  latest  drivers  now  address  the  a/d   (i/q)   directly  , those   shots  are  only  using  the  dongle  , with a  wire to  pin 1 of the  a/d .the  e4000  convertor   chip  is not  used  , , to  use   vhf  , need  to  simply  change the  sample  setting  and  connect the     vhf  Ae to  the  normal  input  
 
Direct  sampling  ...   there  is  no  fall  off  past  1 mhz  ,   that  was  the  504 carrier  to  day  , with  qsb  showing  on Spec-lab in 3D  , had about  25 % cpu  left  on the  old   P4  100MHz   pc ,  will  also   run    sdr  + Opera   or   Ros   [ must  drop  a  dual  core  in some time  !]

Try Cozy Cave
 
TV DVB sticks have been available for 12months at about a tenner (that's Sterling; EU ?). Thought every body had one by now. Using HDSDR with Balint Seber's plug in you can receiver from almost DC to light....... :o) Using an up converter to 60megs plus, will give full HF coverage (LPF's help). The Chip set also allows other tricks that Graham describes look on You-tube.
 
There are other very expensive alternatives beware!

£10 Dongel-SDR  Direct sample on 504 KHz
 
The  latest  window  drives   for  the  ultra-cheap    sdr   dongle   project , now  have the  'direct  sample'  option 
 
all  that  is needed  is  a  wire  to  pin '1'  of the  AD chip  , [ ie  use the  decoupling cap  as a  terminal  post]
 
select  I/Q , and  you  have a  HF rx  , which tunes  down to   zero  (ish)
 
This is the  504  carrier  from my  main Ae  via tuner , showing  qsb 
 
navtex  from the  south coast last  night  518  ,100% copy  , so  not  bad  ..
