DSCF5081 K8JTKHey Gang,
I don’t have to complain to you about the hot and extremely humid weather we’ve had because all of you are living it too. Storm season arrived later in Northern Ohio. I wrote last month how my city got hammered by some storms. It continued with a tornado outbreak in Indiana on August 24th. Friend and regular checkin to the Ham Nation D-STAR net luckily sustained no damage. However, his neighbors a quarter-mile to the north and south had their homes destroyed. The line of storms that moved through Indiana spawning many tornados prompted the National Weather Service in Cleveland to staff the Skywarn desk. I was one of the operators at NWS that night. Though the storms significantly weakened by the time they reached the Toledo area, there was one confirmed EF0 tornado in Pemberville (Wood County – my old stomping grounds). It touched down along route 6 and dissipated quickly but not before removing sheet metal roofing from nearby buildings. No injuries or fatalities.

Public service season is quickly wrapping up for most of the section. Technical Specialist David KD8TWG ran much of the five-day public service event at the Great Geauga County Fair. Being from Cuyahoga county (and the far west end at that), I was a little skeptical. ‘OK the GREAT Geauga Fair.’ But it really was a great fair. It’s the biggest one I’ve attended. There’s a ton of people, displays, awards, animals, events and acts, and yes people really do stand in line 45 minutes for a milkshake. This was confirmed in a casual conversation between fair-goers. As far as ham radio there is a great mixture of technologies including Ohio MARCS, 800 MHz, APRS, Mesh, VOIP, and a portable repeater for their communication needs. It was quite the elaborate setup and really is a great example of utilizing technology to suit communication needs.

The public service season concluded in Cleveland on the 11th with a half-marathon called “River Run.” It was great weather and there wasn’t a single ambulance call. A lot of the ham radio event coordinators have to beg, twist arms, and make many phone calls to get people to come out and help. Please volunteer and help out with these events. You’re there to make sure everyone has a good, safe time during the event. Your presence also gets ham radio out in front of the public and builds relationships with event organizers and county officials. If you’re active in helping out with public service events, you’re more likely to be called in the case of an actual situation.

Ham Nation episode 264 (https://twit.tv/shows/ham-nation/episodes/264) was an episode that featured an all YL cast. Everyone on the show that night was a young lady. The episode highlighted female participation in the hobby and pointed out that ham radio is not made up entirely of OMs. Additionally, Dr. Skov (who is not licensed … yet) gave a detailed tutorial on ionospheric conditions and how space weather effects propagation on the HF bands. She talks about the atmospheric layers, electron density, how those layers change during the day vs night vs gray line, the layers which reflect signals, Kp and X-Ray Flux indices. Her tutorial would have really helped me on those licensing test questions! It starts about 44 minutes into the episode – with some interesting analogies. I will leave it at that!

I’ve been spending a ton of time learning more about the DV4Mini dv4miniand DMR in particular. The DV4Mini is a USB hotspot device about the size of a large USB memory stick. It has the ability to “speak” several different digital modes: D-STAR, DMR, Fusion, P25, and dPMR/NXDN/IDAS. A hotspot is a device that provides connectivity. In this case, to different digital networks from your home PC or Raspberry Pi with a low powered transmitter (usually under 10mW). A misconception I hear a lot and have been asked about: yes you do need a radio for each digital mode you want to operate. To connect to D-STAR reflectors you’ll need the hotspot device and a D-STAR capable radio. Similarly, for DMR talk groups, you’ll need the hotspot and a DMR capable radio. I’ve been hanging out a lot on the Ohio Statewide talk group (3139) and USA Nationwide (3100), I even ran into our own Section Manager on the network!

The more time I spend with the DV4Mini the more issues I find with it. It’s a great concept to have one device to work 5 different modes. The DV4M has a lot of issues that I hope the developers correct related to its performance. I actually bricked mine updating it to the latest firmware. Had to crack the case and put into bootloader mode to re-flash the firmware. The update took the second time. This happened to another user too. Comparing audio quality to repeaters on the network and listening to BrandMeister Hoseline, the audio from the device sounds bad most times and terrible the rest. The direct calling feature doesn’t seem to work. A buddy of mine found the developer for the BrandMeister extended routing feature (DV4MF2) completely ceased development as of September 9th. It will be interesting to see why that happened and if that means anything for the future of the device. There are other hotspot devices out there and I hope to find out more about them soon.

David KD8TWG and his presentation on APRS at the Lake Erie Amateur Radio Association (LEARA) meeting was fantastic. We had a lot of fun with APRS on our smartphones and radios sending messages back and forth.

Thanks to the Cuyahoga Amateur Radio Society (CARS) for having me at their meeting on September 13th. I presented my introduction to the Raspberry Pi computer. Good discussion ensued in both cases on new technology hams can utilize.

Coming up, I will be at the Cleveland Hamfest on the 25th. Two days later I’m giving a presentation at the LEARA meeting on Slow Scan TV. If you’re in the Cleveland area and want to see SSTV in action, stop by the meeting on the 27th. More details will be available at leara.org as the meeting date approaches.

Congratulations to Scott N8SY on being reelected as Section Manager for the Ohio Section. Give him a pat on the back or buy him a beer when you see him for all his hard work!

Thanks for reading and 73… de Jeff – K8JTK

DSCF5081 K8JTKHey Gang,

Where to start?  Lot has gone on the last month.  First up was the Cleveland Hamfest on the 27th.  The weather was great for a change – which, I thought, brought more people.  Seemed to be more flea market and vendor spaces taken up which is always good.  I heard from HAC that it was a successful hamfest this year.  I got to say howdy to a few in the Ohio Section cabinet.  I know I’ll forget someone but thanks to everyone that said hi and congratulated me.  Helped out with some of the local clubs, organizations, and shot the breeze with them.  Spent a couple of bucks too, mostly on connectors and accessories I was looking for.  You can always use more connectors.  Had just as much fun at the after party.

You didn’t know there is an after party?  Oh, there is… just some of my closest buddies getting together afterwards for some lunch.

The following day, I gave my Raspberry Pi presentation for the Geauga Amateur Radio Club and had a blast!  If you’re on the east side of Cleveland, be sure to check them out.  Made for a long day with work but was totally worth it!  There are two versions of this presentation available for viewing on my website at http://K8JTK.org.

The Northern Ohio Amateur Radio Society (NOARS, Lorain Co.) has asked me to put on the Pi presentation for their group too.  I’m scheduled to be the presenter at the November 16 meeting.  If you haven’t seen this thing yet, don’t miss it!  More info: noars.net.

Welcome to Dave KD8TWG as the newest Technical Specialist!  I’ve known Dave since about the time he became licensed because he’s been very active.  In addition to being AEC for Geauga County, he is into embedded systems, computers, and networking.  He plays around with APRS a lot too.

Aside from all that goodness, QSL cards and certificates are coming in from the 13 Colonies and Katrina 10th Anniversary special event stations.  I just dropped off certificate requests and QSL cards for the Route 66 and Pope Francis special event stations.  Groups really put in a lot of work doing these special event stations and do a great job getting the certificates and reply QSL cards out quickly.  The certificates really make great wallpaper for your shack too!  I find special event stations by watching Ham Nation or spots on DX clusters.

The Hurricane Watch Net is celebrating 50 years of service.  It was started in Cleveland by Jerry Murphy – K8YUW as an informal net to provide communication to affected areas.  They activate on the HF bands anytime a hurricane is expected to make landfall.  They can be heard on 14.325 MHz and 7.268 MHz.  Remember to stay clear of these frequencies while the net is activated.  More info: http://hwn.org.

LEARA is in line for a Yaesu Fusion repeater under their promotional deal.  We are eagerly awaiting the arrival of the box and can’t wait to get it on the air.  The promotional deal is a great opportunity for your club to replace aging repeater equipment or experiment with digital modes.  I can’t tell you how excited members of the club are to get into System Fusion.  From the other clubs that have contacted me regarding Fusion, the excitement is contagious.  Give it a shot!  The repeater can be configured: full digital (digital in – digital out only), full analog (analog in – analog out only), or auto detect (eg: analog or digital in – analog out, digital in – digital out, analog in – analog out).

Yaesu has extended the promotion once again until the end of the year, so you or your club has some time to decide.  Details and application are available through yeasu.com -> select Products -> click Digital.  Click DR-1X (model of the repeater).  Click the Files tab -> click “DR-1X Installation Program Application form.”

Thanks for reading

DSCF5081 K8JTKHey Gang.

Normally in this space you would find a well put together article written by Jim W8ERW. If you didn’t catch last month’s Ohio Section Journal, Jim is moving on to bigger and better things. That would be Texas. Jim is one of Fort Worth’s newest residents! The fine folks in the North Texas Section have a great guy coming their way. He’s probably enjoying the warm weather down there right now. Congratulations Jim! So ‘why are we seeing this other guy writing in Jim’s place’ you’re probably asking yourself? I don’t know either.

Seriously though, I have to give a lot of credit to my predecessor, Jim – W8ERW and to our Section Manager, Scott – N8SY. These guys are excellent at answering all my questions from my time as a Technical Specialist and transitioning me into the Technical Coordinator position. Thank you.

I look forward to serving the Ohio Section and seeing what you guys have in store. I’ve already received a number of questions on computers, digital modes, and D-STAR. Happy to answer them. My bio is posted on the Ohio Section website if you missed it.

raspberry-pi-intro-640x420Last month, I gave a presentation on the Raspberry Pi computer at the LEARA meeting in Cleveland. This presentation was an introductory look at the device. It included history, hardware specs, setting up the Pi, and ham radio projects. There was a larger than usual turnout for the meeting and even a few non-hams in attendance. The presentation is available on my website if you would like to take a look. I gave a shortened version at the QCWA Chapter 1 meeting in July. If you missed either meeting, fear not! I am scheduled to be at the GARA (Geauga Co.) club meeting on September 28th as they celebrate 38 years! See you there.
Couple events to note… the Cleveland Hamfest is coming up on September 27th. This is in my backyard so I will be in attendance and hope to meet all of you. You can join the Hamfest Association of Cleveland and help out next year via their website hac.org.

The TAPR Digital Communication Conference is coming up October 9th – 11th near Chicago. Want to go to one of these at some point because it looks like another excellent lineup of forums. Topics include: Digital Voice and Network systems, DATV, Arduino CAT controller for the HPSDR, an Amateur Radio Digital Open Protocol, remote operation of your radio, 3D modeling in Ham Radio, and introductory sessions on a number of topics. ARRL’s own Ward Silver – N0AX is the banquet speaker. Head over to www.tapr.org/dcc.html for the complete schedule and to register.

Thanks to everyone who wrote and congratulated me on my appointment. It really means a lot!
Thank you for reading..
