Re: D4D

It is not recommended as the DSB signal spectrum is not clear due to Inter-Modulation Distortion. It may cause serious adjacent channel interference if you add a PA. Personally I think 1-watt is more than enough for FT8, especially for 20m. BG7IKK already achieved 2 QSO's over 9000km.

How would the D4D pair with a 10 watt linear amplifier like the kit offered by QRP Labs?
