£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  ..
