Amateur Radio News
The waiting game for Hurricane Dorian, the dangerous Category 3 storm, continues in the US Southeast. Amateur Radio Emergency Service (ARES®) teams in the ARRL South Florida Section are reported fully activated, and more than 20 evacuation shelters have been opened. Northern Florida is at a Level 3 status - monitoring the situation, and West Central Florida (WCF) has opened shelters in several counties and is at a Level 2 alert. ARES organizations in all three ARRL Florida Sections convened via conference call on Monday to continue coordination of preparedness activities for Amateur Radio emergency communication.
Compiled by Tom Weeden, WJ9H
The National Hurricane Center (NHC) indicated at 1200 UTC today (September 3) that the eye of Dorian was "beginning to inch northwestward," while the southern eyewall "continues to pound Grand Bahama Island." A Storm Surge Warning is in effect from Lantana, Florida, to the Savannah River. A Hurricane Warning continues in effect for Grand Bahama and the Abacos Islands in the northwestern Bahamas, and for Jupiter Inlet to Ponte Vedra Beach, Florida.
The NHC reports: "The hurricane will then move dangerously close to the Florida east coast late today (Tuesday) through Wednesday evening, very near the Georgia and South Carolina coasts Wednesday night and Thursday, and near or over the North Carolina coast late Thursday."
The Hurricane Watch Net (HWN) has been in continuous operation since Saturday and will remain so until further notice, HWN Manager Bobby Graves, KB5HAV, said Monday evening. "This morning, we had hoped to hear stations on Abacos Island and perhaps some stations on Grand Bahamas Island. Unfortunately, Mother Nature had other plans."
In Georgia, "it's just kinda wait and see," Section Manager David Benoist, AG4ZR, told ARRL on Monday evening. He said the state emergency management agency is fully activated. A statewide D-Star network is in place for passing emergency traffic, should it be needed.
ARES operators have been deployed to two Georgia Emergency Management Agency (GEMA) sites. GEMA will monitor 3.975, 5.335, 7.287, and 3.583 MHz (MT-63 1K), as well as D-Star, and the *Georgia* EchoLink conference node 4544. Coastal counties in Georgia are under evacuation orders, and highways have been reconfigured for one-way traffic to move inland away from the coast.
The South Carolina Emergency Management Agency has issued a civil emergency message due to the potential threat from Hurricane Dorian, and mandatory evacuations have been ordered in several counties.
September 1 marked the 160th anniversary of the Carrington Event, the strongest geomagnetic storm known to have hit Earth since at least the 14th century. The event was named for British astronomer Richard Carrington, who first viewed and sketched the huge sunspot complex on the sun from which a gigantic solar flare -- a coronal mass ejection -- erupted, as he watched. Within hours, Earth was virtually enveloped by an aurora borealis that was visible even at lower latitudes and into the tropics. It was a truly spectacular light show that in some places, turned night into day. When the flare interacted with Earth's magnetosphere, however, it was another story.
This was the Victorian age, when practical wireless was still a few decades off, but the "auroral phenomena," as it was called then, had "a remarkable manifestation of magnetic influence" on telegraph wires -- the internet of the day, as it were. So considerable was the effect that The New York Times reported telegraph operators were able to disconnect the batteries that normally operated the system and were "working by the atmospheric current entirely!" Although the operators subsequently were able to reconnect their batteries, the storm continued to affect the lines. A telegraph manager in Pittsburgh reported "streams of fire" emitted from the circuits. In Washington, DC, telegraph operator Frederick W. Royce was severely shocked as his forehead grazed a ground wire. A witness said an arc of fire jumped from Royce's head to the telegraphic equipment.
The Times account quoted an operator in Worcester, Massachusetts, who said, "During ten years' experience in telegraphing, I have frequently observed the effect of the Aurora Borealis on the wires, but never before have I seen it so grand and appalling."
Operators said that at times the polarity of the battery power supply would become reversed. "One moment the batteries would begin to boil over, and we would have so strong a circuit that the armature would not come away from the magnet; the next moment, there would be no current at all," a report from Quebec recounted.
Based on examinations of ice samples, scientists believe that geomagnetic storms two and three times stronger occurred prior to the 14th century.
After the Carrington Event, scientists began paying a lot more attention to solar phenomena and sunspots. -- Thanks to Frank Donovan, W3LPL

LPFM RULES CHANGES PROPOSED
On July 30th, the FCC proposed a number of rule changes for LPFM Stations. The proposed rule changes (FCC-19-74A1) involved translators and booster stations for LPFM stations, minor change applications, the use of directional antennas and TV channel six protection.
The proposed rule changes concerning booster stations for LPFM stations would allow for an transmitter to be located up to 10 miles from the main LPFM transmitter in urban areas within the top 50 markets and up to 20 miles from the main transmitter in rural areas. The 60 dbu signal contours must overlap and remain within the 60 dbu contour of the primary LPFM transmitter. A booster station is a transmitter that rebroadcasts the stations programming on the same frequency. As the 60 dbu contour of a LPFM station is normally around 3.5 miles, the increased distances for the booster stations transmitter sites are for stations with unusually difficult terrain such as mountain locations where the height above average terrain and transmitter location is high above the area to be served and allows an increase on coverage above the normal coverage for that class of station. The translators which are already allowed for LPFM stations will follow the same separation limits.
The FCC is proposing that a minor application is a change of transmitter site as long as the 60 dbu contours overlap or a move to the same site as the transmitter of a station that shares frequency under a shared time agreement and amendments to those agreements, changes in channel to the 1st, 2nd or 3rd adjacent channel or the 53rd or 54th IF channels (10.7 MHz) and moving either to the same or a nearby location of a 3rd adjacent station.
The FCC is proposing that LPFM stations be able to use a directional antenna when the station is used for transportation or safety use (Travelers Information Service), for protection of a station on the second adjacent channel, and for LPFM stations needing to protect stations in Mexico and Canada.
The last proposal would sunset the requirement that all stations in the 88.1 to 91.9 MHz reserved band would no longer have to protect TV stations on Channel 6 from reception interference after July 13, 2021. Due to the reserved FM band being adjacent to channel 6 there were interference issues from reserved band FM stations which no longer is an issue because of digital TV transmission and the limited number of stations operating on channel 6.
There will be a 30 day comment period followed by a 15 day reply period after the notice is published in the Federal Register.
CHILDRENS TV RULES COMMENT DATES
On August 16th, the FCC published in the Federal Register the summary of the rulemaking on the proposed Children TV Rules. The 30 day comment period started with that publication and ends on September 16th with replies due on October 15th. The FCC notice of the comment dates can be found at (DA-19-794A1) and the rulemaking at (FCC-19-67A1).

RF 201: Module 7: FM Filters and FM Combiners
FM stations sharing common infrastructure, towers and antennas, have challenges to overcome in order to be compliant with the FCC's 47 CFR Part 73 rules, 80 dB suppression from the carrier amplitude, regarding out of licensed channel emissions. Coupled energy between transmitters can cause unwanted intermodulation products that exceed those rules. FM filters have been designed to eliminate the creation of those products in both small and large systems. Design aspects of filters will be discussed including the use of loops, iris and direct couplings. Join us for this webinar co-presented by Tom Silliman, President of Electronics Research, Inc. and Nicholas Paulin, Engineer ERI, who will cover the types of filters used such as notch and bandpass filtering. They will also address the use of commonly used technologies for emissions control and channel combining for shared antenna systems. Custom filter solutions will be covered that isolate FM signals from AM towers and combine analog FM and digital IBOC when transmitter technologies are not used.
