Re: QCX 20M with very low power

Mike Easterbrook

Hi Allison
Does the tuning of L4 have possible relevance to the key shaping &/or instability I am seeing!
I guess power out is easily appreciated (if not easily measured precisely) thus the obsessions with the LPF - I would not have gone looking for a shaping problem but for the instability & having a scope available.
I'm actually happy to keep power out @ 3.5 W to avoid the Instability but now I'm aware of the keying issue am keen to understand it.
Thanks for input
