John - re our discussion on Experimental Radio Service --
Cousin Charlie the radio inspector sez:
" 47 CFR 5.3 is a definition:
(c) Experimental Radio Service. A service in which Radio waves
are employed for purposes of experimentation in the radio art or
for purposes of providing essential communications for research
projects which could not be conducted without the benefit of such
communications.
" The research projects referred to were originally intended to be
research into the propagation of radio waves or the effects of such
on physical or chemical processes, etc. It was NOT intended to mean
provision of communications for someone doing some other kind of
research not involving the nature of radio waves. In other words, the
radio waves were the object of the research, not a tool or means of
instrumentation. Otherwise it could be construed to mean, for
instance, provision of two-way communications for someone doing
research into the most efficient method of dispatching pizza delivery
vans, or garbage trucks, or both in the same vehicle.
" In real life, new and novel ways to use radio communications
properly fall under a *Developmental* authorization in an existing
radio service rather than an authorization in the Experimental Radio
Service. Specific examples from the recent past were the provision of
vehicle location systems and mobile digital data, developmental
authorizations in the various land mobile radio services in years gone
by. Ditto for cellular radiotelephones in the Common Carrier Radio
Service.
But, alas, there arose a new breed in Washington who knew not what
good regulatory practice was, would not listen to their elders and
betters, and therefore would release Experimental Radio authorizations
for any and all purposes, even when they shouldn't. And it makes it
much harder for the working radio inspector, who is the front-line
interface between the radio user and pure chaos, because the folks
involved were prone to grant anything to anyone without adequate
reason, leading to huge screwups in real life.
"And as for remote TV and data transfer for robotics, the Business
Radio Service has plenty of capability in the microwave regions.
Educational institutions are eligible in that service. One should
tailor one's project to live within them or do without.
"Just like driving a car on the highway - how would YOU feel if
soemone somehow got the OK to speed, make unsafe lane changes, etc.
and you had to obey all the regular laws."
Cousin Charlie should know - he's been out there a LONG time!
