I find this distressing and I'll bet the radio astronomers do too. I 
see that they're already saying R.A. will be finished if things carry 
on this way. Whatever happened to the European E.M. standards that 
appear to be so rigid you're in danger of violating them by using an
ordinary radio (oscillator radiation)?? I find the lack of concern on 
the part of the engineers appalling. I thought strict EM controls were
going to be a major part of US legislation? I've heard plenty of 
scare stories over here that made me wonder whether coiling would be 
finished as a hobby.
