I read about these TV dongles, mentioned a few months ago. But this VHF
stuff is uninteresting for me. However, if there are sticks that cover
LF and MF, this could be interesting.
So, what is the name of the stick? Link? "Cozy Cave" leads me to that

UP Convertor ?

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!

£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 ..
