[Elecraft] RTL SDR dongle

[Peter Eijlander (PA0PJE)]

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 two frequency limits.

I suppose you more likely need an attenuator between the upmixer and the 
dongle.

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 amp or not for the K3?
