Net Schedules / Procedures

   The net meets each Tuesday evening on the schedule of this event. Connect activity credits are being awarded for both air time and assistance in developing procedures and antennas directly in support of OHDEN objectives.. The purpose of this net is to practice ICS type message handling between served agencies across the state.

During Daylight Saving Time ( starting on March 12 ), The frequency will be 3584.500 KHz + 1500 Hz waterfall USB using Olivia 8-500.

During Standard Time ( longest winter months), The frequency will frequency is 1804.500 + 1500 Hz waterfall USB using Olivia 8-500.

During the month of March 2019, OHDEN will maintain secondary watch by an Alternate Net Control station on our secondary frequency of 1804.5 KHz to allow stations to check in on both bands and compare signal reports. Check into the primary frequency first and then ( optional if you have the capability ) call in on the backup 160 meter frequency after Primary NCS has recognized you and you have cleared any traffic you have. Be prepared to give the net manager at w5uhq@arrl.net an email giving your reception reports for both bands of the stations you heard or work. 

Both of these frequencies are prime and secondary on our OHDEN frequency plan listed in the OHDEN SOG. See file attachments to our FB page and http://www.theohden.org/ . All EOCs and County Control Stations are urged to maintain capability ( but not necessarily dual operation ) on all OHDEN frequencies.
 

 

 

 

    Check CONNECT OR FACEBOOK for any weekly  changes.

 

    During extreme band conditons, the NCS may post a real time message in the blog to      QSY so it a good practice to monitor the blogs for current information.

 

 
 
  CHECKING IN TO OHDEN
  We encourage the use of this syntax for checking into the net. We call the net by   groups of ARES districts. When your district is called,make sure your transmit data is centered on the NCS waterfall pattern. For consistency, place the string below in one of your programmed macrokeys of FLDIGI. The use of the standard syntax( including the comma delimeters) allows the NCS to quickly paste your check in to   their logging data base. The comma serves as a delimiter (i.e. CSV format) for separating the key data fields of the check in data base. The syntax belowwas developed after a year of trying to balance quick check ins with enough info to make it meaningful; in all situations.

 

 

The standard check in syntax allows the NCS to keep net moving faster and keep all     information pertinent to the check in without reformatting it on the fly.
 
  The standard minimum check in syntax for FLDIGI is:
  <TX>
      <enter><enter> OHDEN de ,<Your_Call> , op name , D# , County Code ,
      QTC or QRU , [optional items ] , Your_Call, bt
      <enter> <enter> <RX>

The <enter> <enter> at beginning of each transmission serves as a separator on receiving endand makes the message always start on a new line. It is especially important for Olivia to give the decoder something to chew on before serious data is sent. Failure to enter these end of line delimeters can cause the first few characters of your data to be truncated to receiver.

See the OHDEN SOG for further information on checking in and passing traffic.
