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!

G.. Unbelivable! Where can one buy that dongle? Do you have a link
for us? 73, Stefan/DK7FC Am 04.04.2013 15:01, schrieb Graham:

£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 ..
