BG2ELG YAOQI It is rumored that the Liaoning license plates also do not include the "U" segment, although it is not explicitly stated on their license plates.
BG5BEE There's nothing specific I want to say; whatever needs to be done, will be done. Amateur radio is just a hobby. After all, it's quite Amateur
BI4MTI In菏泽, segment U stated that they needed to decode the communication, and had been coordinating for a long time. However, unlike Zhejiang and Shanghai, we do not require license holders to specify frequencies and do not impose penalties for non-compliance.
EmptyPan BH4HZD 😂The lowest minimum frequency for downward trending ISS (International Space Station) has also disappeared.
BH4HZD EmptyPan Newcomers ask: Will the U-band downlink signal from satellites be blocked or something?
EmptyPan BH4HZD I was thinking that if I were to stop listening, it could also be considered a violation.
BH7JUO I'd like to share some observations: About 10 years ago, I started noticing a trend in Guangdong where many small repeaters with 3-digit numbers appeared. These repeaters lacked both a license and a callsign, but they still operated according to standard procedures, and the repeater network was well-organized. However, I also observed that some repeaters *with* callsigns were not following proper protocols.
Ken BH7JUO I also noticed this happening in the Pearl River Delta region. It reminded me of seeing many popular mobile virtual networks used by cities in the Pearl River Delta area years ago, where each person had a separate virtual network account on their phone.
dxs660 BH7JUO In Hangzhou, there are also similar U-band black repeaters. They are small accounts used by people who know each other, and it's very enjoyable to chat on them. The key is that they have been operating these repeaters for almost 10 years, and while they have changed frequencies and been interfered with over time, they have never been shut down, and they still work perfectly.
BI4JMS The U-band has a very wide bandwidth, extending to 3G. However, it seems that removing the 400 MHz secondary service is not accurate.
BG5ELQ BI4JMS UHF 300MHz - 3GHz: 430-440 MHz, 1240-1260 MHz, 1260-1300 MHz, 2300-2450 MHz ALL BANNEDThere are no available spare frequency bands.
BI4JMS BG5ELQ Having seen Shanghai surpass all other cities in China, I'm curious to know which city will come next.
BI4MIG It's always a bit over the top, letting the bullets fly for a while. Maybe they'll come back in two days. Logically speaking, even though the amateur radio community is small, there are still quite a few people involved. Try contacting a few Shanghai-based members of the National People's Congress (it doesn't necessarily have to be at the national level; even city-level representatives would work).
BG5ELQ BI4MIG The implementation and prohibition of the use of frequencies in the 430-440 MHz range, as stipulated in the "Zhejiang Province Regulations on Management of Amateur Radio Frequency Use," has been in effect for ten years.
