Sorry, I'm not buying that direct sampling front ends are as prone to
overload as many of the posts are suggesting, especially on 20M and
higher. During the past 3 years, I've worked one CQWW and one ARRLDX
contest from the Northeast with a SteppIR yagi feeding an ANAN-100D with
0dB attenuation and never experienced overload during the weekends. FWIW,
there's a clear indicator on the PowerSDR screen if ADC overload should
ever occur.
The superior rx audio clarity of the direct sampling front end radio is a
game changer to me, although I'm not a fan of computer GUI's. So I'm
looking forward to widespread use of direct sampling front ends by
all-in-one-box hf xcvrs.
