BG2GFC It depends on your needs. If you want a repeater that can cover several hundred meters, buy two 888s, a repeater enclosure, and a duplexer. It cost less than a few hundred yuan. I don't know how I found out, but it was painful.
bg2kud The simplest solution is to use two handheld radios or one handheld radio (for receiving) and a high-power mobile station (for transmitting), plus a universal repeater board. Around $500 should be sufficient.
BI3SDE bg2kud What range can this system cover (e.g., covering the surrounding area, and our dream is to have a repeater in our county)?
bg2kud BI3SDE Based on your antenna's height and the transmitter's power. A properly licensed repeater requires approval before installation.
BG2GFC BI3SDE Remember that UV radiation spreads further with higher intensity. In a county-level city, it's advisable to first assess whether there are enough enthusiasts in your area to support your project. I ended up with nothing left, just a completely empty space, so I had to close it down with regret.
FengziLeo BI3SDE There are probably not many amateur radio enthusiasts in my county, so it's best to try connecting with repeaters in nearby cities.
BI4IVE Two broken handheld radios plus a repeater box. The radios cost 100 yuan each, and the repeater box costs 40 yuan. This totals 150 yuan. However, if setting up a repeater requires notification and approval.
BI6LVP You wouldn't want to secretly take a local repeater home with you, would you?😂So, I'd like to know the price.
BD8ENU It's rare that it doesn't cost a lot of money, and also that the transaction process is difficult.
tudoubocai 丰俭由人，便宜的俩手台+中继盒+双工器+车载天线，500以内。主要是双工器贵。 中等的，两个摩托罗拉300车台，中继板+双工器+短点儿的玻璃钢棒子。1000应该够了。 贵点儿的，就不说了。 最便宜的，收个带差转的二手手台+转接头+车载双段天线，300以内就行。缺点是，要双段台子才能上。 最后这个方案，如果闲手台功率小，可以用车台，但肯定就贵些了。 差转方案有一个无可比拟的优势，就是打法律擦边球，验机就行了，可以不审批中继。
tudoubocai Billrizer The 450C needs to be modified, upgraded, or replaced with a duplexer and antenna. It's essentially the same as two handheld radios, but with a power output of less than 7 watts, making it slightly larger than a handheld radio.
BI4IVE Establish an organization, purchase amateur radio repeater equipment, submit relevant documents to the office, and obtain approval for the repeater's callsign from the office.
Bi4KKF The most challenging aspect is maintaining it over time, as ongoing costs for maintenance, facility fees, and personnel will far exceed the initial equipment cost.
BG2EFX Actually, a repeater isn't expensive; a basic one can cost less than $1,000. The digital resolution can be 2K or even lower, except for D-S. Ultimately, the most important thing is to find a suitable installation location.
bg2qax It seems there's a Hamfish repeater for the Jianwu 820, probably with around 5-6 users. It also has its own power supply and duplexer... all that's left is to connect the feedline and antenna.
