FM Frequency Survey Log Sheets
To help with your survey of which FM frequencies are
already being used in your area,
I've compiled a set of log sheets listing each channel # and frequency in the FM
broadcast band.
Each sheet has spaces for notes and comments about your observations.
Keep in mind that a casual "Home Broadcaster" using just
enough RF power to transmit around their
own house and property shouldn't need to be quite this obsessive when it comes
to choosing
an available frequency. Any frequency that's not in use by a strong nearby
station should be satisfactory.
On the other hand, a micro-broadcaster trying to squeeze
everything they can possibly get out of their
transmitter should make a serious effort to choose the frequency that will
present the least amount
of interference - interference to a licensed station's signal from the
non-licensed transmitter,
as well as interference from the licensed station to the
micro-broadcaster's own signal.
It works both ways.
A careful channel-by-channel analysis of what's on the
airwaves in your area could prove very helpful,
especially in parts of the country where the FM band is already extremely
crowded.
To make the FM Survey Log Sheets as printer friendly as
possible, I've posted each sheet
as a separate webpage which you can open and print directly from your browser.
Try the Print Preview option from the File Menu first to see if you need to
adjust your printer settings.
Each log page should fit on a single 8.5 x 11 sheet of printer paper. Text Size
'Medium' or 'Smaller'
(from the View Menu) should give the best results.

PS: Don't forget to consult the FCC Database Query Page when your frequency survey is completed.
