Tech Classes Move Online
By Dan Romanchik, KB6NU
I’ve been teaching ham classes for more than a dozen years now. My specialty has been the one-day Tech class. In this type of class, you review all of the questions in the question pool with the students over the course of six to eight hours, and then immediately give them the test before they can forget anything.
I would hold these classes three or four times a year and regularly have 20 – 30 students in each class. The pandemic, of course, has put the kibosh on these classes. The last one I taught was in January.
Frankly, I was wondering if I’d ever teach one again. A little over a month ago, however, I was approached by a fellow in Portland, Oregon about teaching an online class for some folks that he’d corralled there. After giving it some thought, I said yes.
So, now, in place of face-to-face classes, I’m teaching online Tech classes. There are plusses and minuses to this approach One negative is that I miss the face-to-face interaction with the students. On the plus side, teaching online allows me to offer classes more frequently. My first was in June. Last week, I completed the second class, and in August, I will teach a third class.
I have had to make some changes to the format. Making people sit in front of a computer for six hours or more seemed like cruel and unusual punishment. So, instead of a one-day class, the online class consists of four, two-hour sessions, spanning two weeks:
• Session 1 ◦ Electrical Principles ◦ Electronic Components and Circuit Diagrams • Session 2 ◦ Radio Wave Characteristics ◦ Antennas and Feed Lines • Session 3 ◦ Amateur Radio Signals ◦ Electrical Safety ◦ Amateur Radio Practices and Station Setup • Sessions 4 ◦ Station Equipment ◦ Operating Procedures ◦ Rules and Regulations
This seems to be working out pretty well. I’m using Zoom, and most people have been able to attend without too much hassle. To simulate the whiteboard that I use extensively in the face-to-face class, I’m using the Autodesk Sketchbook program https://www.sketchbook.com/ and sharing my screen with the Zoom meeting attendees. To write on the “whiteboard,” I’m using a Gaomon M10K2018 drawing tablet.
Sketchbook allows me to build up a document in layers, and the result is kind of a hybrid PowerPoint presentation and whiteboard. I can make layers appear when I start discussing a particular topic and then write over them. For example, when I go over the questions that use Ohm’s Law to calculate current in a circuit, I display the later with “E = I x R” and on a second layer, show how to calculate the answers to the questions
To take the test, students have to sign up for an online test session. Fortunately, several VE groups are offering online, remote testing. To sign up for one of these sessions, all students have to do is go to https://hamstudy.org/sessions. For the first two classes, the W5YI VEC scheduled a special test session.
I foresee teaching these classes monthly until the demand wanes. The next class will start on Monday, August 3. To register for the class, go to https://www.kb6nu.com/product/next-online-tech-class/. To find out when these classes will take place in the future, potential students can sign up for my mailing list by going to https://landing.mailerlite.com/webforms/landing/m6l6t4.

Virtual Meeting, Fallbrook, California
July 4, 2020
Vice-President Ron Patten, KG6HSQ, called the meeting to order at 1500.
Bob, W6VR, shared a full screen picture of a radiation formula that he uses commercially and can also be used by amateurs. Bob invited everyone to take a “screen shot” of the formula for their own use. The formula can be used to determine Effective Radiated Power. Bob described a low-level power test that he and Stephen, KC6MIE, had recently conducted where Bob was doing some transmissions at the micro-watt level.
The pledge of allegiance was done via video and was spoken by the late Red Skelton. As he spoke the words of the pledge he described the meaning of many of the”key” words that make up our pledge.
Ken, W6MF, gave the following financial report.
|Checking Balance May 31, 2020||$7,008.70|
|Petty Cash Balance May 31, 2020||$58.81|
|ARRL Renewal Fees||$140.00
|Petty Cash Balance May 31, 2020||$58.81|
|Expenses June 2020||$0.00|
|Checking Balance June 30, 2020||$7,008.70|
|Petty Cash Balance June 30, 2020||$58.81|
Ron, KG6HSQ, gave a brief summary of the last weekends Field Day Activity. He had a few visitors come by his home during the event. He showed pictures of his setup and explained his operation. During the contest there were other operators that participated in the Club portion of the activity and were at times connected via ZOOM. Ron used the A3 antenna on the clubs trailer/tower from his side yard. He showed his logging program and also some statistics and reports that will be used to enter the contact information with ARRL. (These statistics will most likely be posted on the FARC web page at some time in the future.
Stephen, KC6MIE, said that he had some visitors in his shack as well. He indicated that he was able to complete only one 6 Meter contact. He summed the event up as “It was an interesting time”.
Hayden, KG6YVD, said that he and Krissy, KR6SSY, operated 2 stations and they were both on “generator” power. He showed photographs of his antenna setup and of their contact log. They worked 45 of the 50 states.
Brent, KJ6UMP, presented a program showing the construction of a Remote Antenna Switch. He indicated that commercial switches could be rather expensive, so he chose to construct a switch from components that he purchased and constructed his own 2 position switch. The switch he constructed is controlled by a hard wire but he indicated that similar switches could be controlled by Wi-Fi. He showed a series of progressive photographs of the construction of the unit. He estimated that his total cost for the unit he constructed was approximately $35.00.
Wayne, K6BFR, showed a Lithium-Ion battery that he has recently purchased. He indicated that the unique thing about this particular battery is its weight. Compared to comparable batteries it is very light weight.
Bob, W6VR, said that radio station KFMB, 760, has been sold to IHeart Radio and they will assume the 760 spot on the AM radio dial. Bob indicated that today was the day that the transition was to happen.
There was a discussion about coax cables and cable entries in to houses. Brent, KJ6UMY, showed pictures of a very nice installation at his home where he has brought several cables into the unit. He showed the inside construction/wiring of the cables along with lighting arresters on each in a very nice enclosure. This unit is in a weather resistant “box” and is mounted on the outside of his home.
Ron, KG6HSQ, mentioned that we are in fire season and suggested that members be aware of communications on the repeaters and to keep communications brief.
With no further business the meeting adjourned at 1610.
At one time during the meeting there were 18 members and guest tuned into the ZOOM meeting.
