As the title suggests.
Yesterday (the 24th), inspections were carried out on Qianzhang, Chang, and Changyi along the river for monthly maintenance purposes.(CRH380AJ-0203)Reaching a height of over 30 floors.The visibility was very good, almost excellent.
Here's the situation regarding the movement test I performed that day (I didn't bother to post it on the platform; I just checked what another friend had done at their other location).
Since I had previously tested repeater signals in various locations, including a high-altitude repeater in Wufeng County, Yichang City, Hubei Province (which reached as far as the mountains), I decided to test the repeaters again in different areas.
At that time, I was just trying something out, and to my surprise, it actually worked.
First, let's talk about the topography of Changde. Changde is located in the Dongting Lake plain area, and there are no high mountains nearby. The highest point within the city is Mount Tai (the main peak has an altitude of 568.5 meters).
The equipment used was an LD-6100, which had a genuine antenna and pre-programmed frequencies for all locations.
Based on my actual testing at the car shooting location, I have confirmed that repeaters in Changsha (Black Elk Peak), Zhangjiajie, and other locations are operational. However, local repeaters in Changde are not working.(However, when I opened it, there was hardly anyone there, and essentially, I became the main controller.)
However, the repeater in Yiyang hasn't been opened yet (unknown). Does anyone have a local repeater in Yiyang and know its frequency?
Thank you to BH7FNI and BH7EKR, my friends in Changsha Black Elk Peak repeater and Xiantang Jiuhua repeater, respectively.
Recordings of communications from BH7EKR
I also recorded some myself, but I just didn't bother uploading them to video platforms.
Therefore, in my opinion, as long as you are willing to put in the effort and experiment, anything can be fun (like "doge"). Next time, I suggest trying different antennas or other modifications.

Let's take a look at the location of the car camera ( ).
The distant railway line is the Shilang Line, while the closer one is the Changying-Chang section of the Yuxi-Xiamen High-Speed Railway.
