The tuner chip does have a sort of "bypass" mode that
Eric,
I have a NooElec R820T that does work from 25.85 MHz to 1766 MHz
Anything lower that that needs an upconverter afaik.
I can tell GQRX to go lower but it then detects nothing anymore...
GQRX is a Linux SDR program where a funcion that says "No limits" allows
to tune higher and lower than
These dongles are mediocre, yes they are cheap, but they are virtually
useless for anything other than a door stop.
The lowest cost, but useful, SDR receiver is an SDRPLAY RSP1A. With the
free RSPUno software the RSP1A will track a K3 via Omnirig, clicking on a
signal on the RSPUno spectrum jumps
Regarding the RTL SDR dongle. I notice that it says that the dongle will go
down to 500 khz with reduced sampling below 24 mhz. I wias wondering if one
needs to get an up converter to get it to work? Or will the reduced functioning
be ok for a basic pan adapter. Also, does it require a buffer
