Re: SDR-RTL for longwave and mediumwave

For local stations a v3 will probably suit you.
If you get a little critical then an upconverter will be better.

Re: Stability Issue using Nooelec Up Converter ?.

All radios/converters will have at least one oscillator that may drift. So you have two. How much does it drift? How much stability do you want? The RTL is more likely to drift the most although the converter will as well. A temperature controlled oscillator (TCXO) will usually satisfy most. The V3 ...

The HDSDR one is integrated, maybe the later one is not.
It probably depends on whether you are satisfied with the integrated one or want features offered by the other.

Re: Want to get started ASAP, but overwhelmed by number of options

I'm no expert but the V3 from this site seems guaranteed.
Unless you have a reliable recommendation I'd think waiting would be best.
My guess is that all good ones will be sold..

Re: Anyone tried one of these?

It is not an unknown company https://www.radioenthusiast.co.uk/news/ ... b-is-back/
But not too popular, it looks as if it just duplicates keyboard keys, a tuning know might be provided cheaper, Griffin?.

There are ongoing changes.

Re: New future user - sniffing for interference

Depends on the software you use.
HDSDR can slow down to 24 hours or more.

Re: Instability of SDR# using windows 10 64 bit

Seeing your comment with more information on another thread, do you not even look at the Airspy group?
This has been discussed and cured.
