Holland Amateur Radio Club K8DAA USA

The next HARC Education And Training (E.A.T.) meeting will be held on Tuesday, April 23, 2024 at 6:30pm.  It will be held at the Herrick Library in the GroundWorks space, 300 S River Ave, Holland, MI.

Understanding Modern Electronics: Amplifier Circuits Using Op-Amps

Now that the versatility of negative feedback has been demonstrated, adjust the strength of negative feedback in op-amp circuits to build amplifiers with whatever gain you choose. Create an amplifier that sums two or more inputs, see a circuit that converts current to voltage, and explore the design and operation of an op-amp-based light meter.

…Understanding Modern Electronics…   For those not familiar with the “Understanding Modern Electronics” course, it is a series of video lectures presented by Professor Richard Wolfson of Middlebury College. The course consists of 24 lectures that provide a conceptual explanation of the principles of how electrical circuits work and are used to control everyday devices in our modern world. Components and topics that are covered include transformers, transistors, resistors, capacitors, diodes, semiconductors, Ohm’s Law, and analog and digital levels.

The Herrick District Library is asking that individuals register for this event.  Event registration will open one month ahead of the event.

HARC education and training sessions are open to the public and you do not need to be a HARC member or have an amateur radio license to attend; however, all attendees under the age of 18 must be accompanied by a parent or guardian.  If you have questions about amateur radio equipment, operating practices, licensing, test and measurement, or anything remotely related to amateur radio, this is the place to be.

The next HARC Education And Training (E.A.T.) meeting will be held on Tuesday, April 23, 2024 at 6:30pm.  It will be held at the Herrick Library, 300 S River Ave, Holland, in the Groundworks room.  Groundworks is on the west side of the Main Library’s first floor.

We’ve done this in the past, now put April  27, 2024  on your calendar.

We are looking for volunteers to help out with medical communications for the 2024 Tulip Time parades. This is perhaps our best opportunity each year to represent HARC and amateur radio within our community, and we are providing a critical service to local residents and visitors. It’s also a great time!

Radio operators are paired up with one or more medical personnel and assigned a section of the parade route.  Once on station, we patrol and look for participants or spectators that are in need of medical assistance.  When we encounter a medical need, we relay information regarding the patient’s condition and location to Net Control.  Our Net Control operators work alongside public safety and emergency medical dispatchers to ensure that help arrives as soon as possible.

As to whether Tulip Time volunteers need to be OCEC (Ottawa County Emergency Communications) members, the answer is “NO.”  In addition to OCEC members, ALL members of the Holland (HARC) and North Ottawa (NOARC) clubs are eligible to participate and we welcome all of you!

This year’s parades are on Thursday, May 9th and Saturday, May 11th. We usually meet around noon and are finished by a bit after 4pm on both days. If you’re interested in volunteering, please email me at bossman.mi@gmail.com and let me know which parade(s) you’re available to help.

….Todd Boss W8YHF, 2024 Tulip Time Communication Coordinator

Join us on the 12th of February at the Chick-owa Club, 9279 Ottogan St, Holland, MI 49423 for our monthly meeting, at 6:30pm.  This month, after our Business meeting, the  Presentation will be by Jeff Nonhof, KD9THX. He’ll be discussing Yagi antenna design, antenna design software, gain and how it’s expressed, and will end up with a hands-on demo of how a Yagi antenna’s directivity changes as you add elements.  As usual, Rich will have the coffee going!  Join us for the fun!

Mike, K8NWN, did about three hours of tower work recently on the 30 foot tower on top of the Warm Friend building downtown Holland. The top, off frequency antenna was taken down and side mounted for the Tulip Time Committee’s repeater, an X50 was put on top, (for the 147.50/146.50 repeater) and a 3 VHF element beam, pointed to the end of the Tulip Time parade route was installed, with a colocated UHF beam, to run the temporary remote receiver to the 147.06 repeater for Tulip Time.

If you hear or see Mike, say a lot of thank you’s for his work.
