Content preview: Hello group Tell me more? I have to say an up converter in front of a DVB-T TV stick works well at HF but at MF/LF owing to the necessity of spreading the band (owing to narrow allocation etc) the display presentation is not good. Very blocky I guess as a result of the slower processing but signals don't sound bad. Also the up converter in my case using an SBL-1 whilst fine at HF in terms of gain with no pre-amp at MF appears to need one. RX antenna gain at MF/LF is surely a factor and may be LO injection levels may not be at their optimum in my circuit. I am very interested in the comment about added frequency coverage SANS up converter.

Hello Graham,

I use this rtlsdr with a lf converte= r with SBL1 to monitor the range from
4-140 khz,works very fine for such= a cheap system!

Tnx Eberhard,

I thi= nk with post  dsp  processing the  dynamic range is  increased=   in
narrow  window  ?  but  in 3  MHz w= ill  be  42 ~  ?

There  is  a  version= of the  software  that  enables  use to  be = made of
the  AD  directly  , needs  the  Rf&nb= sp; feed  to  be attached to  one of the
pins , not = the  main  input , with  then  no  need  for= the  converter (not
tried yet as  my  original installat= ion failed  will  need  to  remove  and
start a= gain)

but for  =A313 , not  a bad  system !

73= -G..
