EPAEPTN MOVING BACK November 11, 2009

Once again band conditions have forced the Eastern Pennsylvania Emergency Phone Traffic Net (EPAEPTN) to move.


Remember that the net control on each day may decide to shift frequency a bit to avoid interfering with other stations. I encourage everyone to check in to this net as often as you can to help with any NTS Traffic that might be coming into your area and to meet the fine folks who are always there.

PA Eastern Region 60M Net

From Dennis R. Wells Sr. K1DRW

This coming Sunday morning (Mar 04, 2007) at 8:30am, just prior to the regular Sunday 9am RACES Net on 75m 3.9875, there will be a 60m Net conducted. Note: For those who can't make the 8:30am net, I will repeat the net at noon, local time.

K1DRW, Dennis Wells, located in West Brandywine Township, Chester County (just north of Coatesville) will be Net Control.

The 60m Net is scheduled for operation on Channel 1 (5330.5), with (Channel-2, 5346.5) as an alternative channel/frequency. Please remember the FCC rules for 60m communications (USB and 50w ERP). ARRL 60M FAQ You may be asked to please volunteer a description of your 60m system (antenna, power, location). The purpose of this 60m Net is to provide PEMA Eastern Area RACES amateurs an opportunity to test their stations 60m capabilities and performance. Should the need arise, 60m can be a valid alternative to 75m EmComm operations. This can be especially true when there is a need for EmComm beyond 75m Ground wave range, during midday when 75m NVIS Skywave suffers from severe absorption. For stations employing a horizontal antenna system and checking in within a 50m (approx) radius of K1DRW’s location, communications may be a combination of NVIS and Ground wave. Current NVIS Propagation (foF2) at 8:30am typically does not support 60m Skywave propagation. Recent online data from NOAA indicates foF2 propagation support for 60m Skywave (NVIS) kicks in later, around 10 to 11am. Stations employing vertical antenna systems can expect only the Ground wave component.

Regarding NVIS Skywave communications: If you have an interest in testing 60m when there is clear propagation support for NVIS skywave operations (essentially for those employing a horizontal antenna system), K1DRW will conduct a repeat of the 60m Net at 12:00 Noon Sunday (same day, same frequencies). Please indicate your interest during the 8:30am Net. Regarding Ground wave communications: Recent tests, informally conducted by K1DRW with other Eastern Area PEMA RACES members (no precise measurement devices used) indicate the useful range for 75m Ground wave can be effective out to approx 50 to 60 miles. I have not yet conducted 60m Groundwave testing to determine the effective range. The 75m tests were conducted in the evening, when propagation for 75m NVIS Skywave communications clearly (according to online NVIS propagation data) had dropped off. Currently, foF2 frequency drops off rapidly after sunset in the winter, often not even providing support for 75m. Both vertical and horizontal antennas were compared in the testing.

EPA ARES Digital Network Guidelines

Thanks to the outstanding efforts of Lor Kutchins, W3QA and Bob Wiseman, WB3W the EPA Section now has ARES Digital Communications Guidelines.

The following thanks to the ARRL and THE ARRL LETTER dated October 6, 2006:


A section of the Department of Homeland Security (DHS) 2007 Appropriations Act, HR 5441, formally includes Amateur Radio operators as a part of the emergency communications community. Congress approved the measure before adjourning for its pre-election break. President George W. Bush signed the bill into law October 4.

Amateur Radio is included within the legislation's Subtitle D, Section 671, known as the "21st Century Emergency Communications Act." Radio amateurs are among the entities with which a Regional Emergency Communications Coordination Working Group (RECC Working Group) must coordinate its activities. Included within the DHS's Office of Emergency Communications -- which the measure also creates -- RECC Working Groups attached to each regional DHS office will advise federal and state homeland security officials. The final version of the legislation incorporated language from both House and Senate bills and was hammered out in a conference committee. An earlier version of the 21st Century Emergency Communications Act, HR 5852, included Amateur Radio operators as members of the RECC Working Groups.

In addition to Amateur Radio operators, RECC Working Groups also will coordinate with communications equipment manufacturers and vendors -- including broadband data service providers, local exchange carriers, local broadcast media, wireless carriers, satellite communications services, cable operators, hospitals, public utility services, emergency evacuation transit services, ambulance services, and representatives from other private sector entities and nongovernmental organizations.

The RECC Working Groups will assess the survivability, sustainability and interoperability of local emergency communication systems to meet the goals of the National Emergency Communications Report. That report would recommend how the US could "accelerate the deployment of interoperable emergency communications nationwide." They also will coordinate the establishment of "effective multi-jurisdictional, multi-agency emergency communications networks" that could be brought into play in an emergency or disaster.

In light of the new legislation, the ARRL plans to follow up to determine how it can interact with the DHS and its Office of Emergency Communications.

Driving flooded roads

With the recent occurance of heavy rain, please be careful when driving.
Flash floods can occur any time, bring dangerous road conditions.
The following are important points to remember when driving on water covered roads:

  • Six inches of water will reach the bottom of most passenger cars causing loss of control and possible stalling.
  • A foot of water will float many vehicles.
  • Two feet of rushing water can carry away most vehicles including sport utility vehicles (SUVs) and pick-ups.

  • If you have to drive through a flooded section, do so very slowly, to avoid splashing water on the ignition system or into the air intake.

    We would like you to join our Yahoo discussion group at
    It would be most useful if the Phila ARES members that do use this feature had their ID as their CallSign@Yahoo.com

    This group will be part of our notification process for the Phila ARES orginization.

    EPA RACES 75M Net - Sunday AM

    There is a 75 Meter EPA RACES Eastern Pennsylvania RACES Net
    every Sunday morning at 9AM Eastern Time on 3987.5MHz LSB
    Net Control looks for check ins Alphabetically, by County, Starting at 9AM Eastern Time. . .
    They usually Call for Philadelphia County by 9:05AM to 9:15AM Eastern time.
    We want to see how many check-ins we can get from Philadelphia County ARES.
