If you check the FCC Rules and Regulations for Amateur Radio, no where
does it use the word 'hobby'. It does give five reasons for the
existence of Amateur radio. Part 97 covers the Amateur Radio
regulations. However, it is understood that all of us hams using amateur
radio, do refer to it as a hobby .... hi Hi HI - 73 from Bill - WD8ARZ

Yes, we do have concerns about transmitting, and receiving radio
frequency interference (RFI). Please note that the vast majority of RFI
is not caused by a transmitter. Most of the time it is due to the device
with the 'interference' having not been designed to filter out signals
not intended for it. For example: An audio amplifier used in PA systems
should only handle audio, not radio transmissions. Other devices like TV
that are to receive signals, are only supposed to receive TV and not
transmissions outside its frequency range. Plastic cases, no power
supply filtering, no antenna input filtering, etc etc are what allows
signals to be received when they should not be. If an transmission
source is 'clean' as determined by the FCC, continued interference at a
device is the problem of the device. There are filters and techniques to
fix the rfi issue, but it is not the ham's obligation to do that work or
provide the parts. When a transmitter is in fact transmitting signals
other than it was designed for, it should be shut down until it is
'fixed'. Most of the time interference is caused by too much microphone
audio being driven to the transmitter. Listen on 27.185 MHz. Poor audio
transmissions and rfi causing transmissions can be frequently be found
on channel nineteen. A frequent source of RFI these days is due to the
poorly designed AC Switching Power Supplies used in much of our
Small section of those regulations below:
*PART 97—AMATEUR RADIO SERVICE*
*Subpart A—General Provisions*
*§97.1 Basis and purpose.*
The rules and regulations in this part are designed to provide an
amateur radio service having a fundamental purpose as expressed in the
(a) Recognition and enhancement of the value of the amateur service to
the public as a voluntary noncommercial communication service,
particularly with respect to providing emergency communications.
(b) Continuation and extension of the amateur's proven ability to
contribute to the advancement of the radio art.
(c) Encouragement and improvement of the amateur service through rules
which provide for advancing skills in both the communication and
technical phases of the art.
(d) Expansion of the existing reservoir within the amateur radio service
of trained operators, technicians, and electronics experts.
(e) Continuation and extension of the amateur's unique ability to
enhance international goodwill.
