Ah 8970, those were the days

Right now, Stefan's signal is doing something different to
carrier.

Rain all day here otherwise I would probably be using Stefan's
carrier to test my replacement E-field rx.  I built this over
a year ago but haven't got it working properly yet.  On the
bench it has a lower noise floor but not so good connected
to the antenna.  The problem is with the line driver not
cleanly handling the strong 50Hz component. It raises the
noise floor by just over a dB.
