Do you have what it takes to be a Technical Specialist?

Technical Specialist: "Responsibilities:

Serve as a technical advisor to local hams and clubs. Correspond by telephone and letter on tech topics. Refer correspondents to other sources if specific topic is outside TS's knowledge.

Serve as advisor in radio frequency interference issues. RFI can drive a wedge in neighbor and city relations. It will be the TS with a cool head who will resolve problems. Local hams will come to you for guidance in dealing with interference problems.

Speak at local clubs on popular tech topics. Let local clubs know you're available and willing.
Represent ARRL at technical symposiums in industry; serve on CATV advisory committees; advise municipal governments on technical matters.

Work with other ARRL officials and appointees when called upon for technical advice, especially in emergency communications situations where technical prowess can mean the difference in getting a communications system up and running, the difference between life and death.

Handle other miscellaneous technically-related tasks assigned by the Technical Coordinator."

Have you heard about N5M? #ARRL #hamradio

The amateur radio community is preparing for its' support for the 2015
Oklahoma City Memorial Marathon.  This year is special as it is the 15th
anniversary of the Marathon and the 20th anniversary of the Murrah Federal
Building bombing.

To commemorate this special year, we are adding a special event station/s
leading up to the Oklahoma City Memorial Marathon with the call sign N5M.
The special event stations will be in the Oklahoma City Metropolitan area
and begin operating on 19 April at 0000Z and end operations on 26 April
(race day) at 1800Z (1 PM local when the Marathon is officially over).

On race day, we will have a special event station on the race course located
at the Britton Med medical station at Mile Marker 13.  You are also invited
to assist in operating that station on race day.

The format of operations will be similar to Route 66 On The Air, i.e.
register as a special event station and sign up for specific operating
dates, times, band and modes.  You may operate, using the call sign N5M,
from home, your mobile, or other locations in the Oklahoma City Metropolitan

If you wish to volunteer to operate as a Marathon Special Event station,
contact one of the following Marathon Special Event site administrators to
get registered to have access to the scheduling page:

Tom WA9AFM/5

They will need the following info to grant you access:  Name, Call Sign,

The special event site administrator will send your username (usually your
call sign), a case sensitive password and the link to the Marathon Special
Event scheduling page.

Please Note: you don't have to be a Marathon volunteer to be a special event

Thanks to Tom, WA9AFM for this report.

Oklahoma Section Automatic Packet Reporting System Network April 11 event #ARRL #hamradio

The Tulsa Digital Radio Club (KT5DIG) will sponsor 2015’s first OK Statewide APRS net at 1300 CDT on Saturday, April 11, 2015.  The frequency will be the nationwide APRS calling frequency, 144.390.MHz  The lead net controller will be Scott Haley KD5NJR, operating the station KD5NJR-6 from the greater Tulsa area.  During the net, he will use a variety of paths in an attempt to eventually achieve statewide coverage over the course of the net. 

This is an opportunity to exercise your APRS station by sending and receiving APRS messages as well as the more common position reports.  Oklahoma hams are encouraged to monitor the net activity and provide reception reports of stations heard on 144.390 to Scott

Scott will monitor the Tulsa Amateur Radio Club linked system and the DMR State-wide talk group during the net.
The net will start at 1pm Central Daylight Time.
It will last for about 1 hour depending on the number of checkins.

APRS is a convenient mode for the exchange of short messages and position reports.  In particular it is used by the storm spotting community and the NWS.  The APRS mode is also used on HF and via satellites.  Balloons and other experiments use the format too.  It’s an interesting skill to have in your amateur radio toolbox.

You can participate in the net in a variety of methods
1)      Those with APRS trackers can activate them and confirm with net control via voice.
2)      Those with the APRS-enabled HTs (Kenwood Th-d7, d72, Yaesu VX-8, etc) can formulate a  brief message to kd5njr-6
3)      Home stations may participate too.

A typical home station would consist of a radio ,  computer and either a TNC or rig interface with software modem.  Popular APRS software include UI-VIEW32 and APRSIS-32.  Many Linux users use XASTIR.
Those without a TNC may look into the UZ7HO or Direwolf software modems.  AGWPE is also a popular software modem.  They use the computer’s soundcard to carry out some of the TNC functions.

Hams may also refer to the KT5DIG website : or find us on Facebook.

G4ILO has good APRSIS32 primers.

Good luck and see you on the air.
