This month’s presentation topic is “Solar Power by Jay Nugent, WB8TKL”. Jay will talk about Solar PV panels (types, price and efficiency), Charge Controllers (PWM/MPPT), battery banks, battery types/chemistries and efficiency vs cost, wiring your house for 12VDC, proper wire gauging, fusing/protection, how to modify existing fixtures for 12 VDC use, DC-to-DC converters for running things that aren’t 12vdc (laptops, flat-panel TV’s, etc.), availability of 12VDC ceiling fans, fridges, water pumps, and the list goes on. Oh! And we can’t forget about running our Ubiquiti AREDN nodes off 12vdc, too!

The General Membership Meeting will be held tomorrow, Wednesday, September 13th in Room 2424 at the University of Michigan’s Space Research Building.

This month’s presentation topic is “Ham Radio Mesh Networks”. We will talk about ham radio mesh networks specifically, AREDN (Amateur Radio Emergency Data Network). There has been renewed interest in the Club to build a mesh network in the area and we have toyed with this idea a few years back using HSMM-Mesh but never discussed it in detail. HSMM-Mesh is no longer in development and AREDN is being used predominantly all over the world. If you have any experience with ARDEN and mesh networks, in general, your input will be valuable and if you have a device with the firmware loaded please do bring it to the meeting. We will watch a presentation and then discuss further on how to implement if there are enough of us willing to put up the nodes.

This month’s presentation topic is “Connectors… Connectors… Connectors…”. We have had some requests from members of the Club about how to solder a PL-259 connector. So we will look at the various connectors that are in use today and how to install a PL-259 and an N-connector onto a piece of coax. If you have any weird connectors that you would like to show off to everyone please bring them along.

Amateur Radio Volunteers Support Michigan’s “One Helluva Ride” Bicycle Tour

From the ARRL News Desk: http://www.arrl.org/news/view/amateur-radio-volunteers-support-michigans-one-helluva-ride-bicycle-tour

07/12/2017
Some two dozen Amateur Radio volunteers supported communication for the Ann Arbor Bicycle Touring Society’s (AABTS) 41st running of the One Helluva Ride (OHR) bicycle tour on July 8 in Michigan. The race derives its moniker from the fact that the longer route options pass through the town of Hell. The annual loop tour, which starts and finishes at the Chelsea Fairgrounds, offers rides from 15 miles to 100 miles. This was the 27th year that the Arrow Communication Association (ARROW) — an ARRL Special Service Club — has overseen the communication infrastructure and supplied SAG support (for those “sagging behind”).

“There are many places on the route where cell phone coverage is marginal, making Amateur Radio an excellent choice,” said George Byrkit, K9TRV. “Small beams are deployed at the food stops to provide more reliable communication with net control.” Byrkit served as the morning net control station, while Dan Romanchik, KB6NU, handled the afternoon shift.

ARROW had support from the Chelsea Amateur Radio Club (CARC) and the Livingston County Amateur Radio Klub (LARK). The operation employed two of the Chelsea club’s 2-meter repeaters, which were linked to broaden the coverage.

The hams provide SAG vehicles as well as volunteers to ride along in AABTS vehicles. Among other non-communication tasks, they provide spare tire tubes, foot pumps, food and water, and transportation for those experiencing mechanical failure or exhaustion. Hams also are placed at each of the three food stops.

This year, 100 riders registered for the 15-mile fun ride for youngsters with parents. Some 1,500 riders took the longer routes. No serious injuries were reported.

In addition to Byrkit, volunteers included ARROW President Dinesh Cyanam, AB3DC; George Byrkit, K9TRV; Dan Romanchik, KB6NU; Dave New, N8SBE; Mark Goodwin, W8FSA; Ulysses Balis, N4IYL; Faye Ogasawara, KE8DDB; Jameson Eisele, KD8PIJ; Steve Bemis, W8AYN; Don Winsor, AC8TO; Bob Lyons, KI8AB; Eric Lyons, KC8GBR; Jim Lommel, WD8RWI; Quentin Guzek, KD8IPF; Sam Spiteri, K8NOS; Steve Andre, WB8WSF; Jay Nugent, WB8TKL; Mary Anne Nugent, W8VWY; Joe Glandorf, AC8ES; Willie Peloquin, N8WP; Bruce Freeburger, KD8MFR; Rick Pugh, WR8W; Jim Jagow, KD8TBT; Steve Rogacki, AC8GO; Glen Bowe, KT8KTU; Ralph Katz, AA8RK, and Lawrence Davies, K4ETD.

“These hams drove over 2,400 miles, providing SAG support,” Byrkit said. “Ninety-five percent of the SAG drivers are ham radio operators. The other cars have hams placed in them so that communication with them is possible over the entire route. Ham radio has the benefit of being able to find out who is nearest to someone needing help, unlike cell phones. At least 8 of the vehicles were pinging their locations via APRS.”
