Re: NooElec. HF Upconverter
David J Taylor
Perhaps the question should be "Why do you think you need an amp?"
As Tom says this is not an amp. It is an upconverter. The V3 is supposed
to cover HF so the V3 should not need an amplifier or upconverter.

The RTL-SDR V3 uses "Direct Sampling HF Mode", which is a rather limited bodge and is not as good as an up-converter add-on. Even then, the dynamic range of an up-converted RTL-SDR V3 may limit its application in a busy HF environment, even if RF filtering is used.
Serious HF use needs a better receiver.
