      Main SDR problem is ADC overload as useful data are lost. PC sound
      card has about 100 dB dynamic range and line-in input should survive
      inband strong signals which are not controled by narrow RX AGC loop.
      Local TX in M/M environment should be eliminated with decent RX BPF.
      Skimmer recovery time from local inband TX is very fast and bandmap
      filling between CQs works. It is up to contest software to manage
      large number of Skimmer posts. N1MM Logger with Access database does
      it fine. Only visual display gets overcrowded. My experience is based
      on FT-1000MP SDR on both RX 455 kHz IF in busy CW contests.
