Another Statewide APRS Net - THIS SATURDAY #ARRL #hamradio

It's that time again,  the Tulsa Digital Radio Club will hold an APRS net at 1300 CDT on Saturday.

Net control station will be Scott Haley KD5NJR.  

Hams are encouraged to check-in by sending an APRS message to KD5NJR.

As an exercise, try the ANSRVR server.  Subscribe to the OKAPRS group for the duration of the net. Instructions are here :

The Statewide DMR talkgroup will also be monitored.

APRS messages can be generated from
  • certain HTs and mobile radios (ex: Kenwood TH-D72, TM-D710, etc
  • .smart phones with APRS apps,
  • computers paired with TNCs and radios, and (example : UI-VIEW)
  • computers with soundcard-based modems and radios. (example : UZ7HO Soundmodem and APRSIS32

We continue to operate HF APRS using the instructions located at .  As an additional incentive for this upcoming net, a certificate of appreciation from the Tulsa Digital Radio Club (TRDC) will be sent to those stations that try this new high-tech wrinkle on the two decades old HF APRS mode.  The HF APRS net will be running on 7036 kHz at a center frequency of 1000 Hz using MFSK-16 for highest robustness during the net.

Popular for about 20 years now, APRS is a format for sending short textual messages over amateur radio.  Short bursts of APRS can conserve your battery power and radio spectrum.  It lends itself to low power applications such as travelers, backpackers and in emergency situations.  APRS radio sets are popular with hikers, experimenters (model airplane and rocket enthusiasts) and there is even an APRS terminal on the International Space Station.   Background information is available at :

Put Howard to work at @W1AW #ARRL #hamradio

The "Put Howard to Work" event, which was to be presented on Monday, May 13, by the ICQ Amateur Radio Podcast and feature ARRL CEO Howard Michel, WB2ITX, has been cancelled. Here is the official statement:

Earlier this week an announcement was made that ARRL CEO Howard Michel, WB2ITX, was going to be on air at Maxim Memorial Station W1AW on Monday afternoon, May 13, with the intent of giving ARRL members a chance to chat with the CEO and get to know him better as a ham. However, an issue was raised about this being a potential violation of FCC rules, in particular, Section 97.113 which states that "A station is also not allowed to transmit communication in which the station licensee or control operator has a pecuniary interest, including communications on behalf of an employer."

Given that the ARRL is Michel's employer, and that there was an effort to publicize an event at which members of the organization could chat with the CEO, such an event could be perceived as a benefit to the organization.

So out of an abundance of caution and to avoid any potential violation of FCC rules, or even an appearance of a violation, Michel has decided to suspend plans for the "Put Howard to Work" event that was scheduled for Monday, May 13.

The March of the Ants continues #Skywarn #ARRL #hamradio

At Spotter Network, work continues to improve reports.  From years ago to today, there's around 67000 users and more buyin from emergency management and National Weather Service personnel.

In a recent email, Spotter Network reports:

SN Members Submitted 3,226 reports:
189 tornado reports.
172 funnel cloud reports.
355 wall cloud reports.
846 hail reports.
571 wind reports.
539 flood/flash flood reports.

With encouragement to keep accounts current, those who did not get an email from Spotter Network will find their account suspended.  Check your Spam folder.

There's even a place for you to put your ham radio (or other) callsign.  While hams are getting on board with that, local government operators are also putting their unit numbers there.

Please support your local Skywarn program but use Spotter Network too.  Your report goes directly to the NWS office serving your location (you forgot to check the phone number before you left today).  Expect a call from an emergency manager or the Weather Field Office, if they have questions about the report or are looking for a followup to it.

Remember ACES and be safe.  Oh, and the march of the ants refers to the little red dots on RadarScope showing the position of Spotter Network users.
