Thanks for you ticket reply to my question, Hans. I've ordered one of each Progrock2 and QLG2. It would certainly be considerably cheaper than the alternatives! They will be boxed with a stable psu and I will see if buffering and filtering are required. Would be a great solution for Pluto based QO100 transceivers where even with a new, high stab tcxo, on tx it still drifts.
