- Subject: OPS - Direction finding in the RACES
-
- Question: What role does direction finding have in the RACES, if
- any?
-
- Response: Direction finding - the process of locating Radio
- Frequency signals by other radio equipment - has a tremendous
- role for Amateur Radio operators, particularly in urban areas.
- RACES units have been called upon to locate spurious signals from
- a variety of sources from malfunctioning equipment, such as stuck
- transmitters, to deliberate jamming of local government or other
- facilities.
-
- One direction finding response involved successful location of a
- moving radio that virtually crippled a major police department
- radio system. One of the departments handheld radios moved from
- officer to officer as the shifts changed and as they moved about
- the city. The particular radio had a unknown habit of keying up
- at odd intervals while in the belt holster of the officer. Since
- the mike was against the officer's body, little could be heard in
- the way of sound but it was wiping out the entire system. Each
- time the interference went off the air, and the others on the
- frequency were advised to switch channels, so did the unknowing
- officer. Consequentially the interfering signal followed every
- move to a different channel. Until the problem was solved, the
- department thought they had a deliberate jammer, when in fact it
- was malfunctioning commercial equipment in an "impossible
- configuration that just couldn't happen" but did!
-
- In addition to such uses for direction finding, as in the RACES
- type operations, there are others as well; the "fox hunt"
- (direction finding contest) of the local Amateur Radio club being
- an example. Such activities range from an ongoing "sport" to the
- real preparation for serious and dedicated direction finding.
- Both aspects have their place, but those who see "fox hunts" only
- as a pastime and purposely overlook the serious nature of the
- work that can be done, are a discredit to the Amateur Radio
- Service whose primary purpose - as set forth in FCC regulations -
- is public service. (eom)
