APRS
We have setup a APRS iGate, Digipeater and Weather Station with the callsign KC2NJV-10.

A iGate takes APRS packets heard via RF and transmits them via the internet to the APRS-IS (APRS Internet System). A Digipeater essentially does the opposite, takes packets heard either on the radio or the internet and forward them via RF.

The Weather Station retransmits the METARs (Meteorological Aerodrome Report) from Farmingdale Airport (KFRG), which is approximately 9 miles from the location of KC2NJV.   KJFK (JFK Airport) is 13 miles and has significantly different weather patterns.

APRS Text Net

We have created an APRS bot (click here for more info here), that will take messages and re-transmit them to individuals who sign up for the APRS net. One message will go to all who have subscribed.

Note: This Net does not reset daily. The concept is an emergency notification system, as such, if you wish to unsubscribe (see commands below), you must send a text message.

A BIG Thanks to Ben Jackson, N1WBV for reworking the APRSPH.Net bot published on GitHub.

We send out multiple Bulletins, Beacons and system updates daily. This DOES NOT MEAN YOU ARE SUBSCRIBED. You must specifically do that yourself.

Emergency Pagers
ERLI operates two POCASG (DAPNET) transmitters.

POCSAG (Post Office Code Standardisation Advisory Group) is a one-way digital paging protocol used to transmit data to pagers. It's an asynchronous protocol that allows for the transmission of tone, numeric, and alphanumeric messages. POCSAG was developed in the 1980s and is still used in some areas, particularly for critical messaging systems like emergency services.

The DAPNET (Decentralized Amateur Paging Network) is a network operated by amateur radio enthusiasts. It links all the Ham Radio pager transmitters together (think AllStar for paging). Ham operators can get their own paging number, similar to a DMR ID.

Pages are limited to 80 characters! Thus certain alerts may be truncated or sent in two different page messages.

Please Note: Unlike text messages, pages are not stored and forwarded. Thus once a page hits the transmitter, it is broadcast. If you are out of range, you won't recieve the page. Some alerts are re-broadcasted due to the time limits we've setup.

There is a transmitter in Queens and in Plainview. These transmitters are tuned to 439.9875 MHz.

While anyone can listen (decode) Ham radio transmissions, only licensed Hams can send pages.

We broadcast alerts on rubric ("talk group") 1038. NOAA weather alerts are on rubric 1081. You need to program your pager.

You need to when they have been classifed as "major" or "severe", as well as some that are informational throughout the day. Some may never be sent, i.e. Terrorism Adivsory, others are daily.

In an emergency, we can broadcast unlimited number of pages.

Reading a METAR

METAR or SPECI: Indicates whether it's a standard METAR or a special (SPECI) report, which is issued when significant weather changes occur.

Airport Identifier: The ICAO (International Civil Aviation Organization) code for the airport or weather station.

Date and Time: The first two digits indicate the day of the month, and the last four digits indicate the time in Zulu time (UTC), always in the format HHMMZ.

Wind:

  1. Direction: Three-digit code indicating the direction the wind is blowing from, measured in degrees (000-360).
  2. Speed: Two-digit code indicating the wind speed in knots (KT).
  3. Gusts: "G" followed by the maximum gust speed in knots, if gusts are present.
  4. Variable Wind: "V" followed by the range of wind direction variation (degrees) if the wind is variable.
Visibility: Indicates the minimum visibility in statute miles (SM).

Present Weather: Abbreviated codes indicating precipitation, obscurations, and other weather phenomena.

Sky Condition: Indicates the amount and type of cloud cover using abbreviations like FEW, SCT, BKN, OVC. Mulitple number by 100 to give altitude, i.e. 075=7,500; 250 = 25,000.

Temperature and Dew Point: Indicates the current temperature and dew point in degrees Celsius.

Altimeter: Indicates the barometric pressure at the airport in inches of mercury.

Remarks (RMK): Additional information, such as wind shear, runway conditions, or other relevant data.

APRS Text Net Info
 

Our rolling 7 day log can be found HERE.

If you send a text message via APRS to ERLI (example), the following commands apply:

Note: I've eliminated the need to add ERLI to all commands EXCEPT "CQ"
  1. CQ ERLI [message] <-- This will subscribe you to the List and everyone will receive your message(s). Note: You must have a message, "Hi" works.
  2. NETMSG OR MSG [message] <-- To send a message to all users.
  3. NETUSERS <-- To see users of the net.
  4. NETCHECKOUT <-- to leave or unsubscribe from this list.
  5. Ping <-- Response should be Pong.
  6. ?APRST or ?Ping? <-- The response should be something like "KC2NJV-4>APRS,TCPIP:".
  7. version <-- The responsse is something like "3.11.6 (main, Sep 12 2023, 13:12:45) [GCC 11.4.0]".
  8. time <-- The response should be like "Localtime is 2025-07-01 14:37:00 UTCEDT".
  9. help <-- The response should be "Valid commands: ping, version, time, help".

    NOTE:

  10. Unknown command <-- "I'm a bot. Send 'help' for command list".

Abusive behavior will cause your callsign to be blacklisted

APRS Announcements, Bulletins and Beacons
We send out multiple Announcements, Beacons and Bulletins per hour. Plus some Bulletins on holidays.

Only subscribed HRO will receive Announcements.

Announcements are sent several times a day, because APRS has no "store and forward" capability (as do cell phones. Think about when you take a flight. When you land you immediately turn your phone back on and get a flood of text messages. That's Store and Forward. With APRS, once a message is released, and you miss it, you've missed it!)

Because you receive the Bulletins and/or Beacons DOES NOT MEAN you are subscribed to the ERLI APRS NET!

Bulletins and Beacons are part of APRS and are a normal occurence. Odds are your APRS unit is sending a Beacon.
