Building on the previous post, which discussed my ideas about the link.
~It has been a month since my last post, and I should have followed up after that, but due to karma being-1 caused me to be unable to post anything. I summarized it in one sentence:Please speak carefully.。
The key nodes involved in setting up this link are listed below.
(Cause): After finishing my high school entrance exams during the summer vacation, I was at home and experimenting with radio. Because I was at home, the signal was poor, and I could only connect to the local repeater station. Direct mode communication was almost impossible, and I couldn't receive many signals. In order to receive more signals, I went to higher places (e.g., the roof). When I woke up in the morning, I might go for a climb (because I was going to another neighborhood without an elevator card), and it was quite tiring to do this every day. So, I had an idea: why not build my own repeater testing station?
(Below is the result of step 1) I immediately got to work. At the time, I didn't have a duplex system or a perfect receiving and transmitting radio; I only had a few basic walkie-talkies and a lot of enthusiasm. Within less than a day, I successfully built my first homemade wireless repeater test station. I then packaged it into aMixue BingchengInside the insulated bag, I placed it on a rooftop. While there wasn't any real significance to it, I was already thrilled when it could transmit signals.
(Here are the results for case 1.) The result was that after only one day, it ran out of power and shut down. At the time, I had built it myself, but I hadn't added a protective plate to the battery, which caused significant damage to the battery. The voltage was unusually low, and since then, I've been thinking about building another one someday.
(Here's the transitional paragraph.) Because my first attempt involved retransmitting the received electromagnetic waves as electromagnetic waves, a legally compliant amateur radio repeater requires numerous procedures, so my first one was...Black repeater, which resulted in the following events:
(Below are the results from step 2) If I want to do it legally, I will build a non-transmitting device, so I thought about forwarding to the internet for my personal monitoring. I just did what I said, and with the help of kind people, plus local HAMs providing ideas, methods, and hardware support, my second-generation wireless repeater testing station was born. This time it finally has a decent enclosure, solar charging, and a large battery.
(Here are the results for case 2.) On August 26th at approximately 5:00 PM, I returned to the neighborhood with excitement and installed my latest setup on the rooftop. By August 11th, this amateur radio repeater had successfully transmitted signals for [duration].More than 2000 timesFunctionsBasicNo problem.
The following are two observations made during the operation over the past few days:Problem:
①: Intermittent signal (This is due to the antenna; I am using the original antenna.)
②: There are problems with the electricity supply (inefficient solar power generation).
Regarding these issues, I have also developed some potential solutions. However, due to time constraints (as the start of school is approaching), I don't have enough time to implement them. Currently, this setup can last for a maximum of two days. I will try again during my winter break.
