Why
are we private?
The UHF community of
Southern California in particular has evolved over many years as
primarily a den of various private single-site or multi-site radio
systems. Hence, this is in part a 'cultural phenomenon' of the area.
There are reasons why this developed. Some of them extend to simple
matters of FCC Rules. Repeater owners have the discretion to limit the
use of a repeater to a private group of individuals. Auxiliary Station
owners have no such choice. They must regulate
the use of their stations to specifically authorized individuals per
FCC rules. Anyone interested in reading the legalese should consult the
FCC rulebook. The GRONK Radio Network consists of Remotely
Controlled
Base Stations, or 'Remote Bases'. These stations are not "repeaters",
rather they are auxiliary stations.
While they are capable of Mobile Relay operation, this is but one
function of the station. This is much different than a typical single
repeater or small linkage of 2-meter repeaters. So, not only are there
legal concerns, lying beyond these are two major reasons why most
larger and sophisticated UHF networks are private:
We put a lot of time, effort and
money(!) into building and maintaining these radios. Most of us can't
afford to support one without financial help. It is common to establish
clubs or informal organizations and collect dues to finance operations.
In the case of GRONK, it is a "benevolent dictatorship" owned
and
operated by a single individual. Dues are collected to finance site
rental costs and site upkeep. Limiting network access to members
provides an incentive for interested individuals to join the
organization and help support it. We also like to know the folks using
our radios. A radio system is somewhat like an extension of one's home,
and therefore its inhabitants an extension of family. Not something to
be taken lightly.
Nearly all of these networks (UHF
and otherwise) require the use of function codes to activate links, use
the autopatch, and operate remote bases. Improper use of the codes can
put equipment into configurations that may cause harmful interference
or result in illegal operation. Members of these groups are considered
full 'control operators', which carries both responsibility within the
group and legal responsibility as an amateur licensee. Such groups
require their members to learn proper operating procedures and
responsible equipment operation. Permitting unsupervised use of such
systems would require constant monitoring by the owners, which of
course is not practical - nor legal.
Years ago, access to these
systems were "controlled" by requiring PL
tones to activate mobile inputs. The frequencies and tones were closely
guarded secrets in the era of crystal-controlled radios & one to
four PLs per radio. Some groups even took crystals & channel
elements from members' radios and filed off the frequency markings to
prevent them from being known. Most handheld radios could only generate
a handful
of tones and were difficult to change, i.e. DIP switches or
frequency-resonant reeds. The result was a fairly effective control
mechanism. Fastforwarding to the present, every radio available now
supports PL. Some also support its sister technology DPL (Digital
Private Line). Mere seconds to a few minutes are required to determine
the PL tone for any repeater these days. It's a very different world.
