The  latest  window  drives   = for =20 the  ultra-cheap    sdr   = dongle  =20 project , now  have the  'direct  sample' =20 option 
 
all  that  is needed  is  a  = wire =20 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  ,=20 which tunes  down to   zero  (ish)
 
This is the  504  carrier  from my  main = Ae =20 via tuner , showing  qsb 
 
navtex  from the  south coast last  = night =20 518  ,100% copy  , so  not  bad  ..
