The ChatGPT AI engine and ham radio

In case you've been living in a cave for the past few months, the ChatGPT AI engine is taking the world by storm. Between students using it to write term papers and Microsoft announcing that it is incorporating the technology into a variety of its platforms, including the Bing search engine, it's taking the world by storm. There are estimates that ChatGPT reached 100 million monthly active users after just two months.

I've been checking out ChatGPT through my role as a cybersecurity researcher at S&P, and it occurred to me to check it out to help answer questions and solve issues around amateur radio. And while it's not perfect, I am pretty impressed at some of the results that it generated. Here are a few examples:

"Describe the advantages and disadvantages of random wire antennas in amateur radio"


"Random wire antennas, also known as long-wire antennas, are a common type of antenna used in amateur radio. These antennas are simple, inexpensive, and easy to install. Here are some of the advantages and disadvantages of using random wire antennas in amateur radio:


Cost-effective: Random wire antennas are inexpensive, making them a popular choice for amateur radio operators on a budget.

Easy installation: Random wire antennas are simple to install, making them a good choice for amateur radio operators who want to get started quickly.

Versatile: Random wire antennas can be used for a variety of frequencies and modes, including shortwave and long-range communications.

Convenient: Random wire antennas are portable, so they can be taken on trips and used from different locations.


Low efficiency: Random wire antennas are less efficient than other types of antennas, so they may not provide the best performance.

Limited range: Random wire antennas have a limited range, so they may not be suitable for long-range communications.

Requires matching: Random wire antennas require a matching unit to work effectively, which can add to the cost and complexity of the setup.

Vulnerability to interference: Random wire antennas can be vulnerable to interference from other sources, such as power lines and electrical devices.

In conclusion, random wire antennas are a popular choice for amateur radio operators due to their cost-effectiveness and ease of installation. However, they have some limitations, including low efficiency, limited range, and vulnerability to interference."

Not bad! I take issue with the statement around "limited range", as my random wire antenna has allowed me to make over 2,000 confirmed QSOs in well over a hundred countries, the rest of it is pretty spot on!

One more example:

"How do i maximize output efficiency in amateur radio transceivers?"


"To maximize output efficiency in amateur radio transceivers, there are several steps you can take:

Choose the right power source: Choose a power source that provides a stable voltage to your transceiver. A 12V DC power supply is typically sufficient for most amateur radio transceivers.

Use the right antenna: Choose an antenna that is designed for the frequency range that you plan to use your transceiver on. A directional antenna will typically provide more gain than an omnidirectional antenna, but it will also be more directional.

Set the right output power: Use the minimum output power necessary to achieve reliable communications. This will conserve battery life and reduce the amount of electromagnetic interference generated by your transceiver.

Optimize your modulation: Ensure that you're using the correct modulation type for the conditions you're operating in. A digital modulation type will typically provide more efficient use of your transceiver's power than an analog modulation type.

Use proper impedance matching: Make sure that the impedance of your transceiver, antenna, and feedline match. This will ensure that the maximum amount of power from your transceiver is being transferred to the antenna.

Use efficient components: Use components that are designed for efficient power transfer, such as low-loss coaxial cable and low-loss connectors.

Minimize intermodulation distortion: Intermodulation distortion occurs when two or more signals mix together in your transceiver and produce unwanted signals. Minimize intermodulation distortion by using a high-quality transceiver, and by avoiding the use of multiple radios in close proximity to each other.

Note: Before making any changes, it's important to consult with a professional if you're not familiar with electronics and electrical wiring."
Again, pretty solid advice! I've heard stories of people actually having ChatGPT write a textbook on ham radio topics--when I get a little more time, I'm going to continue playing with it. We live in an amazing, and not a little scary, time.....!
