Dynamic range or transient recovery ?
This seems to show the noise floor in
the -90 area , DSP is never mentioned in these
dynamic range adverts , designed to
link large db range to large amounts
of $$ , post processing , produces ranges
far greater than the basic bit count ,
besides if you Tx into it , its only a
£15 fizz not $1000 fut
Unlike the simple £5 ones of
course ,which have 2 lives , one as
24 to 1700 MHz Rx , then , when you
destroy the front end , a blob of
solder , and you have a dc-20 MHz sdr add
a little gain from a mini whip and you
ready for winter

G..
This is all useless unless the device has a sufficient
DYNAMIC RANGE, which should be at least 80 dB, better 100 dB, for LF here in a
2000 km radius to DCF39 /HGA22. And this is most unlikely...
So, another nice
cheap chinese game to play with, but nothing serious...
