CLUB REPEATER INFORMATION:

The repeater logbook is now online

  • 146.640- Repeater: The WH6CZB repeater operating on 146.040/146.640 MHz is the primary two meter repeater serving the Laie and Kahuku area of Oahu.  It is linked to the 146.760- MHz repeater located at Peacock Flats, near Oahu's North Shore.  These two repeaters, when linked properly, provides excellent coverage all along Oahu's North Shore.

  • 146.660- Repeater: The WH6CZB repeater operating on 146.060/146.660 MHz is the primary two meter repeater serving the Waimanalo, Kailua, and Kaneohe areas of Oahu.  This repeater simulcasts on UHF, on 449.150- MHz.  On April 1, 2003, this repeater became the temporary home of IRLP Node 3197.

  • 146.760- Repeater: The KH6FV repeater operating on 146.160/146.760 MHz is the primary two meter repeater serving Oahu's North Shore from Waimea to Kaena Point.  Located on a mountaintop called Peacock Flats, this repeater is linked to the 146.640- MHz repeater located in Laie.  These two repeaters, when linked properly, provides excellent coverage all along Oahu's North Shore.  In June 2003, this repeater became the home of IRLP Node 3668.

  • 146.800- Repeater: The WH6CZB repeater operating on 146.200/146.800 MHz is located 2,000 feet atop the Waianae mountain range at a site called Mauna Kapu (translated into English from Hawaiian: "Forbidden Mountain").  While this repeater serves the entire Leeward Coast, Ewa, Kapolei, and Waipahu areas, it covers an area all the way east to Kaimuki.  When propagation on 2 meters is booming, amateur stations along the Kona Coast of the Big Island can reach the repeater.  This repeater simulcasts on UHF, on 444.100+ MHz.

  • 146.880- Repeater: The WH6CZB repeater operating on 146.280/146.880 MHz is located at about the 550-foot elevation of the northeast flank atop Diamond Head Crater.  This is the clubs flagship repeater, as it serves all of Honolulu, including parts of Leeward, Central, Windward Oahu and the western half of Molokai.  Many transient and local hams use this repeater for general communications.  Also, this is the primary public service event repeater for most events in Waikiki and the Honolulu Marathon.  This repeater simulcasts on UHF, on 444.500+ MHz.  During periods of maintenance, the repeater will remain active without the courtesy tone or hang-time.

  • 146.980- Repeater: The WH6CZB repeater operating on 146.380/146.980 MHz is a local area repeater serving downtown Honolulu and surrounding communities.  It is located on the rooftop of the Honolulu Municipal Building at 650 S. King St.  This repeater simulcasts on UHF, on 448.700- MHz.

REPEATER RULES AND REGULATIONS:

COMPLIANCE WITH PART 97 OF THE FEDERAL COMMUNICATIONS COMMISSIONS RULES IS REQUIRED AT ALL TIMES!

  1. Monitor the repeater to become familiar with any peculiarities in its operation.  This is a good suggestion but don't be afraid to jump in and "get your feet wet" and enjoy the fun.

  2. To initiate contact, simply indicate that you are on frequency.  For example, "This is WH6CZB monitoring."  Or, "This is WH6CZB listening."  It is very likely that you will get a return call.

  3. Identify legally.  You must identify at the termination of your transmission and at least once each ten minutes.  This also includes "kerchunking", which is not desirable practice and in fact is illegal operation.  Also the practice of keying the repeater, without identifying, after a QSO has terminated to show a final acknowledgement is illegal as well.

  4. In calling another station, it is conventional to state the station to be called first, then your call, e.g., "WH6CZB, this is KH6ABC calling."

  5. Pause for the courtesy tone after each transmission.  If the courtesy tone is not present, pause anyway.  This allows someone with emergency traffic; or someone wishing to make a call on the repeater; or other operators wishing to enter the exchange to be heard.

  6. When you have an emergency and need to use the repeater, and it is in use, wait for a pause between exchanges and then use the pro-words "BREAK BREAK" and identify yourself.  The other stations should acknowledge and stand by for you to complete your emergency transmission.  On the repeater, the word "BREAK" should NOT be used to just enter the conversation.

  7. When you wish to join an ongoing conversation, wait for the pause between exchanges and then say, your callsign--"KH6ABC", or your suffix--"ABC".  Then wait for one of the other stations to acknowledge you.

  8. Keep your transmissions short and thoughtful, especially during the morning, noon, and evening drive times when more operators may need to use the repeater.

  9. Remember, our club has several two-meter repeaters.  If one repeater is active and you need to contact someone, or you expect someone to contact you, try the other repeater.  With the new rigs having scan capabilities it is easy to monitor several frequencies at the "same" time.  Choosing a simplex frequency among friends has gained some popularity.  This practice frees-up the repeaters as well as making your conversation a bit more private like.

  10. If your conversation is going to be long and the other station is within direct contact range, go to a simplex frequency.  It is "more" like a private conversation than what the repeater produces.  This also permits other stations, who require the repeater to make a contact.

  11. Use the minimum amount of power necessary to maintain communications.  However, you deserve to have a clear communication.  If possible, don't subject your contact to a noisy transmission if you can clear it up with a little more power.  Some communications are marginal only because one operator likes to use the absolute minimum power.

  12. Don't break into a contact unless you have something to add.  You wouldn't walk down a street and just enter into a group's conversation just because you heard them say something that reminded you of a "cute" story.

  13. Respond to calls for assistance or just conversation.  Our repeater is known as a friendly repeater.  Let's keep it that way.

NET INFORMATION:

Net Manager: Kevin Bogan, AH6QO

Purpose: The nets provide the training grounds needed in order to become an effective communicator in both emergency and public service sectors.  This four-fold approach allows the Net Control Station (NCS) and check-in stations to: 1) practice handling messages and traffic, 2) assess equipment and communications capability, 3) develop and promote brevity over-the-air, and 4) disseminate amateur radio information and related news in a timely manner.  The first three points are emphasized below:

  • Importance of handling traffic/messages: The first three points are the most important for the success of any net.  As an NCS, you would want stations to know how to properly handle traffic/messages by knowing proper phraseology and protocol when transmitting or receiving messages for another station or government agency.  Likewise, receiving stations should be aware of the protocols used when handling with traffic/messages.  This includes proper use of ITU phonetics when checking in on one of the regular training nets.  On fun nets, checking in with easy-to-remember phonetics such as King Henry Six Jolly King George is permited; however, on the emergency training nets, please check in with the standard International Telecommunications Union phonetics.  This standard of phonetics allows new hams and served agencies to understand what is being said.  New hams and others will be exposed to "DX" phonetics later.
     

  • Importance of assessing equipment and communications capability: Second, knowing the capability of your equipment and communications from various locations is important.  Net Control, check-in stations, and those already in QSO must be able to transmit and receive messages with little or no interference as possible.  Self-training, testing, and investigations play a dynamic role in making sure that your communications gear are not only in proper working order, but are situated in a way in which you will be able to initiate contact with another station during emergencies and non-emergencies with minimal difficulty.  If you are unsure of your signal into the repeater (especially those on portable or on the fringes of the repeater), please ask before continuing your QSO.  If you're portable and walking, and on the fringe of the repeater, stop where you are and make your transmission.  Nothing is more frustrating than hearing severe "picket-fencing" on the repeater.  You will have to repeat your message, a time-consuming method that takes up unnecessary air time.
     

  • Importance of "brevity" on the airwaves:  Finally, brevity over the air is very important.  During an emergency or public service event net, we must always assume that emergency traffic can and will be transmitted when you least expect it.  By promoting brevity, you are transmitting a message that is concise and to the point; one that is not long-winded and one that does not take up unnecessary air time.  How do you practice brevity?  Listen to a few public service event nets and ask yourself, "what can I do to keep this transmission short and to the point?"  Another good example of brevity in communications is to listen to police (if you're able to), fire, or ambulance radio transmissions.   Mastering brevity takes time and takes a lot of practice, but when you get it, you'll certainly gain an appreciation for it, and you will expect others to do the same.  If you would like to learn more about emergency and public service net operations, please be sure to visit the net guidelines page.
     

EARC Net Information:

  • Net Control Stations (NCS) are needed.  Please e-mail Kevin Bogan, AH6QO at kevin.(deletethis)bogan  at(@)  gmail.com.

  • To encourage you to learn what an NCS does, try it out!  Ask to take an evening, and if you want to be shadowed -- we'd love to help get you started.

  • Remember: Reluctance and jitters are easily replaced with a sense of accomplishment after taking your first net.  This is a training net, and constant practice will make you a better operator.  Having NCS experience is an invaluable skill to have because in an emergency -- YOU may be called to run a net at a moments notice -- can you do it? 

  • The Net Preamble Script is now available in HTML format.

  • The Net Logsheet is available for download. (PDF format)

  • For tabulation purposes, net statistics are due on the last day of the current month.

  • Please email the Net Manager the monthly stats.

  • Please contact us if you have any comments, questions, and/or concerns.

  • If you cannot make your scheduled net time, especially on weeks we have meetings or events, please try to find a replacement and notify the Net Manager of the results.

  • Nets are usually not held on the fourth Thursday of the month.

  • Thank you for your continued support of the EARC!

  • Also seeking additional net control stations (at least 2 per day, rotating every other week).
