Re: QMX LPF for [40m/30m] - Version 1 measured results


 

Is there a need to improve to meet -43dBc max harmonic or the UK emission standard? I guess the answer depends on how balanced the push-pull is?

JA requires -60dBc but they may not give a license to a transmitter that can transmit off-band including 60m (not allocated to amateur service in JA), so designing a filter bank for them is only a thought exercise at this point.
