Inquiring minds want to know<

Jake, ' Solid state' provides a living for the XYL and myself - she teaches people how to use her company's software to design 'bit freak' (i.e. digital) integrated circuits. I do (these days) advanced systems design on ICs and systems for such applications as radios in pacemakers, swallowable endoscopes, hearing aids, pulse oximeters and the like. In this field, QRO is 1 milliwatt, and a high antenna gain is -10dBi. I suppose it's a bit like prostitution, politics or the law  - it pays the bills but it's hardly respectable.

So us 'Low Mu' cathode followers are strictly Hollow State at home. If it don't glow, it don't go! Even these new fangled ceramic tubes are a bit suspect......you can't necessarily see them glow. My father in law worked on transmitters with 100kW demountable (continuously pumped) tubes, so it is something in the family. I rather fancy using some of the old tubes with fused silica envelopes...if it needs less than 2kV, it's not worth having.

season's greetings
