All of them use reasonably good crystals or crystal XOs. Certainly a lot better than the RTLSDRs most of these were intended for.
I assume that you're talking about frequency stability, rather than gain stability?

Hi all, Has anybody been using any of the upconverters for SDR and has anybody made any comparison of them? I've seen some comments suggesting that many of the low cost models have poor thermal stability[1], has anybody seen problems with this in practice for receiving modes like SSB on amateur HF bands? If this is an issue, is anybody aware of alternative models that are more robust?
