LAFD - Auxiliary Communications Service (ACS)

"The Los Angeles Fire Department is proud to have widespread support from the Amateur Radio community in Southern California.

If you are a licensed radio amateur (aka Ham Radio Operator), or would like to become one, we welcome you to join or support the efforts of the LAFD Auxiliary Communications Service (ACS), a local Fire Corps program.
For those in Los Angeles who would like to participate or monitor, the LAFD ACS Radio Net operates each

Monday night at 7:30 PM local time.
Those interested can check in on or listen to:
147.30 MHz (+) PL-110
-or-
224.68 MHz (-) PL-114"

These frequencies serve the LAFD ACS Net for routine matters only at that time. If you join or monitor, you will be able to participate or listen to roll call, visitor and guest check in, as well as announcements of upcoming events.

ACS is an integral part of the Los Angeles Fire Department's communications infrastructure and has the full support of LAFD Administration. ACS volunteers are considered vital in supporting a wide variety of Department operations, especially in times of duress.

"The K7RA Solar Update
SEATTLE, WA, Dec 2, 2005--

Daily sunspot and solar flux averages over the past week were down, and the geomagnetic indices were up. Average daily sunspot numbers were down nearly 15 points to 33.7, and average daily solar flux declined nearly 13 points to 84.2.

Currently sunspot and solar flux numbers are rising due to Sunspot 826, which is growing rapidly and moving toward the center of the solar disk, giving it maximum influence here on Earth.

It also could be a source of flares, which would not be good for the ARRL 160 Meter CW Contest this weekend. Predicted solar flux for Friday through Monday, December 2-5, is 100, 105, 105 and 105.

Predicted planetary A index for the same days is 15, 12, 8 and 5, although those numbers will be higher if Sunspot 826 becomes especially active. "

ARRLWeb: FCC Affirms $42,000 in Fines in Radio Jamming Case

"FCC Affirms $42,000 in Fines in Radio Jamming Case

NEWINGTON, CT, Dec 2, 2005--

The FCC has affirmed a total of $42,000 in additional fines against reputed Los Angeles-area radio jammer Jack Gerritsen, ex-KG6IRO.

The FCC released the two $21,000 Forfeiture Orders (NOF) just days before Gerritsen is due to appear in federal court to stand trial on a felony charge of malicious interference with a communications system operated by the United States and a misdemeanor count of transmitting radio signals without a license, according to a statement earlier this year from the office of Debra W. Yang, US Attorney for the Central District of California.

If convicted, Gerritsen, 68, could spend up to 11 years in federal prison.

In affirming the fines, the FCC again turned away every argument Gerritsen offered in responding to each Notice of Apparent Liability (NAL), including a 'freedom of speech' claim. "

Poway Antenna Ordinance Travails

Poway Antenna Ordinance Travails

"LATEST POWAY ANTENNA ORDINANCE UPDATE NOV 21, 2005

City Of Poway Readies Amateur Radio Antenna Ordinance

San Diego County Amateurs Are Asked To Support The Ordinance Effort

Over the past three years, amateur radio operators worked with Poway City staff members in writing an antenna ordinance for regulation of amateur radio in Poway.

The work culminated in a draft ordinance that will be presented to the Poway City Council on 6 December 2005, recommending approval of the ordinance as written.

San Diego County hams are asked to support the ordinance by attending the Poway City Council meeting on December 6th."

The Inverted L antenna

"RADIO HABANA CUBA
THE EVER-POPULAR INVERTED 'L' ANTENNA
BY ARNIE CORO (CO2KK)
Host of 'Dxers Unlimited'

SEND YOUR COMMENTS,
QUESTIONS AND IDEAS
DIRECTLY TO ME AT: arnie@radiohc.org

Ever wanted to install a shortwave receiving antenna FAST?!!! Then I am almost sure that you will want to learn more about the 'Inverted L' antenna... About the easiest effective skywire to build ...
Just two supports... may be two masts, a mast and a tree, a mast and a nearby building... it need not be perfectly horizontal above ground... as a matter of fact if the inverted 'L' is installed in a slightly tilted angle it seems to work better.

Although strictly speaking a true inverted L has the downlead connected to one end of the horizontal section... my version calls for connecting the downlead (a single wire) to a point about 20 percent from one end.

The antenna should be connected to your receiver via an antenna tuner with a real wide matching margin. For a 10 to 15 meter horizontal section, strung between two masts of about 5 to 7 meters each, you may expect very nice performance on frequencies extending from about 3 to 30 megahertz."

Grounding is key to good reception

Grounding is key to good reception

In your recent post you advised that coax should be grounded at two sites, first at the antenna and then just before entering the house. Is there an advantage in grounding at more than these sites?
With grounds the most common experience is 'the more the merrier'.

As you add more, however, you usually reach a diminishing returns (no pun intended) situation where there is no *observable* improvement: that's usually a good place to stop.

There are also exceptional circumstances where grounding increases noise problems, but these, in my experience, are much rarer than the pundits who preach against 'ground loops' seem to think.

Even a semi-quantitative theoretical treatment of grounding in oversimplified situations requires heavy math at RF. Experimentation is thus required even if one has done elaborate calculations. It's often easier to use the theory as a guide to what to try, and then experiment."

LOW REACTANCE MULTIBAND CENTER FED WIRES

"LOW REACTANCE MULTIBAND CENTER FED WIRES

An antenna system is more easily interfaced to a radio when the input reactance at the feedline terminals is low or close to series resonance.

If a center fed dipole is fed with a length of low loss balanced transmission line, the input reactance is a function of both transmission line length and antenna length, and to reduce the reactance at selected frequencies there are optimum lengths of dipole and feedline.

The G5RV antenna design is an example of selecting these lengths to produce near-series resonances at amateur operating frequencies from 3.5-28MHz.

There are other combinations of feedline length and dipole length which reduce the overall reactance as shown below.
