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!

Unbelivable! Where can one buy that dongle? Do you have a link for us?

£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  ..
