Hello Andy,

I have used a RTL-SDR.Com V3 dongle running in direct sampling mode under SDR#.

You should be aware that it lacks sensitivity at LF and is prone to overload 
from Medium Wave 
broadcast stations. A tuneable pre-amplifier will take care of these problems.

Though only 8 bit, with correct gain distribution results are excellent when 
using a suitable 
antenna. I have used it with a mini-whip and also with a triangle 10 meter 
circumference 
'large aperture' loop, feeding a LZ1AQ amplifier.

73,
Roelof Bakker, pa0rdt
