Watched the video. I think I had that same Radio Shack SWR meter back in 1981.

Nice design.

Most short-wavelength broadband antennas are defined by an angle, as is this one.

Thanks. Once testing resumes I’m getting my Technician License.

Take the practice tests until you score over 90%. Then take the actual test.

Y’all, I know this is going to sound like a stupid question but....

I have heard of HAM radio since I was a youngun. I never really paid attention to it, but it has been on my mind lately.

What is HAM Radio?? (please don’t laugh, quiet chuckles are ok)

Short answer by a non HAM

Ham radio is/are radio frequencies that can be used by the civilian population. Due to the fact that radio frequencies can overlap and interfere with each other, there are laws regarding the power, frequency and use of the radio spectrum. The HAM licenses are obtained by passing certain tests that cover both the technical aspects of radio wave generation, propagation, reflection and reception of radio as well as the operational and legal issues regarding the actual use of the publicly available frequencies. The licenses and associated tests are of different levels of complexity and the higher level licenses grant an increased use of radio spectrum.

In summary:
HAM radio can be transmitted on if you have the correct license. These frequencies often travel longer distances than CB radio or are repeated. Some short wave frequencies given the right conditions can reach significant (over the horizon) distances. The radio equipment cost varies from non-trivial to expensive. Time investment, like any hobby, can be significant. HAM is often the radio of last resort / first operation in the event of a disaster.

Amateur radio, also known as ham radio, is the use of radio frequency spectrum for purposes of non-commercial exchange of messages, wireless experimentation, self-training, private recreation, radiosport, contesting, and emergency communication. The term “amateur” is used to specify “a duly authorised person interested in radioelectric practice with a purely personal aim and without pecuniary interest;”[1] (either direct monetary or other similar reward) and to differentiate it from commercial broadcasting, public safety (such as police and fire), or professional two-way radio services (such as maritime, aviation, taxis, etc.).

The amateur radio service (amateur service and amateur-satellite service) is established by the International Telecommunication Union (ITU) through the Radio Regulations. National governments regulate technical and operational characteristics of transmissions and issue individual stations licenses with a unique identifying call sign, which must be used in all transmissions. Amateur operators must hold an amateur radio license which is obtained by passing a government test demonstrating adequate technical radio knowledge and legal knowledge of the host government’s radio regulations.

Radio amateurs are limited to the use of small frequency bands, the amateur radio bands, allocated throughout the radio spectrum, but within these bands are allowed to transmit on any frequency using a variety of voice, text, image, and data communications modes. This enables communication across a city, region, country, continent, the world, or even into space. In many countries, amateur radio operators may also send, receive, or relay radio communications between computers or transceivers connected to secure virtual private networks on the Internet.

Back in the 80s the books i found easiest to learn from were the Radio Shack ham books.

It gave you the question, had the 4 possible answers, then a short paragraph on the why of the answer.

Sadly Radio Shack changed their business model and are no more.

Thank you to both of you. I did not know that there was a test involved, but it makes sense since you are operating on radio frequencies.
It gives me more to think about.
That is why I really like free republic, ask a question, get a real answer.
Thank you.

I use an app called Ham Study on the iPhone. It’s basically all the questions and practice tests. There are no study materials. It’s somewhat rote. But it seems to work.
