- BULLETIN 345 MGT ACS/RACES Plans 3/3
- Release Date: September 26, 1994
-
- ACS/RACES relationships are based on leadership and
- cooperation, NOT on hierarchical power positions. Hence, no one
- level of ACS or RACES Radio Officer has more authority than
- another, such as a county RACES Radio Officer over a City RACES
- Radio Officer, or a State Radio Officer over a County Radio
- Officer. Each Radio Officer serves the one government for which
- he/she is the unpaid government public safety communications
- employee. Each has the responsibility and authority only for THAT
- specific jurisdiction, state, county or city. These three levels
- of government involved with RACES plans work on the basis of
- mutual aid and cooperation, NOT authority. Part of that
- cooperation is submitting city plans to the county and county
- plans to the state for approval-concurrence. As a matter of self
- protection a jurisdiction may reasonably require official
- signatures on a plan before it concurs.
-
- The level of communications nets for an ACS/RACES plan
- are basic. A city plan addresses city to county, intra-city, and
- maybe inter-city communications. A county plan addresses county
- to state, intra-county, and possibly inter-county communications.
- A state plan addresses state to counties, intra-state government,
- interstate, state to Federal government, and possibly state to
- public utility and other essential communications. There is no
- FEMA or Federal RACES. However, a Federal government radio
- station may enter a RACES net. Such net levels are graphically
- depicted in the new California State plan. An emergency
- communications reserve plan should reflect current conditions,
- not plans long out of date. A communications plan does not
- discuss what might be or what is planned for the near future.
- Remember the old saying about the best laid plans of mice and
- men?
-
- For a copy of modern county and city plan formats, send a 3.5"
- disc with return SASE mailer to this office; For DOS it is in
- ASCII but WITHOUT graphics. For the MAC, its in MSWord 5.1 with

- BULLETIN 346 Category: Management - Overview:
- Release Date: October 3, 1994
-
- RACES, What's That?
- Ever see that question in the eyes of someone who has
- just heard that term, possibly for the first time?
- Well I do, far too often. At State OES there is a
- constant stream of officials from an agency somewhere around the
- country. Sometimes the introductory remarks of the staff person
- that brings them in will include a phrase like "this is our
- RACES". All too often, I perceive the visitors mental question,
- "RACES, what's that?". Sometimes it's very obvious and asked out
- loud. Other times it may remain unvoiced. It is usually
- accompanied by a slight change in the way their head is held as
- their "body language" projects that mental question to a phrase
- that has little or no meaning to that person.
-
- So how do I respond? Well, that's the interesting part.
- When the explanation avoids the use of the term "Amateur" I find
- that they leave with a good understanding of our Auxiliary
- Communications Service. But if the term "Amateur", as in Radio
- Amateur Civil Emergency Service", is spoken, there is almost a
- guaranteed response; one that few of us would appreciate. That
- response is a far too often 'shutting down' of further curiosity.
- Something in the term "amateur" triggered an association that
- stifles further openness or interest. Oh, they may be polite and
- listen but its easy to tell they have already closed down their
- mental process to what is being said.
-
- Those who work with people are aware that interpersonal
- communication is fragile. That process begins with a thought in
- your mind; then you express it in words so I become aware of it
- as well. My senses hear or see what you say, along with what you
- don't say, which usually shows up as unspoken "body language". In
- response my mental process INTERPRETS that sensory input and the
- result becomes your "message" as I received it. It may be close
- to what you had in mind as you spoke your words, but it may be so
- far removed from what you had in mind that you'd never believe it
- could be that different. If somewhere along the way something in
- your words or your silent body language triggers another image or
- thought in my mind, I may be totally distracted and never hear
- the rest of what you say. In a way it's a wonder we humans
- communicate to any great degree at all. Probably even marvelous .
-
- So how does that apply to the topic "RACES, What's That"?
- Well, check next week for the sequel!

- ABSTRACT
-
- This work was presented as a talk to the Homebrew Special
- Interest Group (HB-SIG) of the Raleigh Amateur Radio Society
- (RARS), on 15 January, 1991 and was revised for another
- presentation on 26 January, 1994.
-
- This document contains excerpts of the National Electrical
- Code (NFPA 70-1990) that, in the author's opinion, apply to
- the installation of amateur radio equipment as would
- commonly be found in most amateur radio stations. Direct
- excerpts from the Code are contained within inset
- quotations. Paraphrased excerpts from the Code are
- itemized. The author's interpretation and discussion of the
- Code is set full-width. The author's interpretation and
- discussion of various sections of the Code is not meant to
- be all-encompassing, nor the official interpretation of the
- National Fire Protection Association, nor of any offical
- governing body having legal authority of jurisdiction over
- electrical installations, but is meant to be used as a
- teaching tool for amateur radio operators.

-
- 1. You are confusing the log-periodic antenna with the log periodic
- dipole array (LPDA). They are not the same thing.
-
- 2. VHF TV antennas are not straight-out-of-the-textbook LPDA's
- anyway. On high VHF band (channels 7 thru 13), the elements are
- 3/4 wave length long and swept forward to form a sort of V-beam to
- get extra gain. (Ever wonder why only VHF TV antennas have swept
- elements, not UHF TV or any other LPDAs?). Hence one set of elements
- handles both high and low band.
-
- 3. Winegard makes a UHF TV antenna that is LPDA at one end and parasitic
- (Yagi type) at the other end. Works pretty well.
-
- If you build a conventional LPDA from a book, you will definitely be
- at a disadvantage compared to the exotic commercial tricks I've listed
- above.

-
- When most people speak of "kerchunk" (which is a hard word to use
- seriously in a conversation!), they are referring to the act of keying up
- the repeater just to see if its there, and not identifying.
-
- Yes, if you do as you say, and identify within the next 10 minutes, then
- everything is fine. But yes again, it is indeed a rules violation if you
- just key up and don't identify.
-
- Clear now?

-
- Be forewarned, some will probably jump all over you for that comment
- there. It's been a muchly heated debate as to whether or not you can go
- for that first 10 minutes without identifying. You know, "well, yeah..
- the rules SAY that, but they don't MEAN that". I just ignore everyone
- and keep operating the way I operate, which has yet to find any
- complaints so far...
-
- Talk later!

- I don't want to cause a stink, but I don't think that's correct. By all
- means I'm not implying that I am in favor of kerchunking, but I don't think
- it's a rules violation if you kerchunk.
-
- Now, if you kerchunk, and then never begin a conversation, then yes it's
- an unidentified transmission and against the rules. But, on my side of the
- world, many hams kerchunk a repeater before they give a general call to
- rid the air of the repeater's CW ID. Then, after the ID has stopped, they
- call who they want to talk to. Remember that according to the rules,
- a ham station can initially talk up to 10 minutes without giveing their call.
- But, after the first 10 minutes is up, it has to be done every 10 minutes
- thereafter.

- As I recall from the days when I was G5BKN, we had (and I assume that

- There was no 50 Mc/s allocation there.

-
- This isn't true Bruce if one of the stations is quite weak; you're
- assuming all stations will have the same signal strength into the
- repeater.
-
- As an example, if two repeaters share the same output with one quite
- weak, when the stronger one keys up there will be no hetrodyne squeal
- from the more distant weaker machine.
-
- I'm going to call the local FAA office and speak with a tech to get
- the definitive answer.

- We had some 6 meter AM activity here in the Portland, OR area about a year
- ago on 50.4 Mhz. I have a Clegg 99'er and I gave my Clegg 66'er to a guy
- up North of Vancouver, WA. About 4 stations were successful in contacts

- rigs back on! Antennas are always a problem for 6, but I guess the quarter
- wave ground plane works easiest. Most of those old rigs use a multiplication
- factor of 6 so 8400 Khz is the right rock.
