GT12Pro能不能买？有谁上综测测试过灵敏度吗？打算买个功率大些，能UV差转的手台。看来看去，只有森海克斯GT12Pro合适。有蓝牙，也方便放在车里。但好多人说GT12很多问题，不知道Pro有没有改进。有这个手台的ham说说。谢谢！

买了，没有试过。只为APRS，期待官网版本快更新[upl-image-preview uuid=fb817608-a759-4998-a781-7f87509f892c url=https://storage.hamcq.cn/2025-02-07/1738948141-649553-20250208010414.jpg alt={TEXT?}]

功率大，带差转，或许考虑一下欧讯UV2Q？（新出的泉盛机器似乎也可以差转）

@"tudoubocai"#p51948 ，我使用GT12做日常V段通联一年多了，除了购买时蓝牙是坏的，换机过一次，其它ok，节假日登山必带，通联功率足，音质和电池续航也不错。

@"BH9FXF"#p51975 大佬，你的GPS信息是手动输入还是内置的模块实时测量

@"BG5ELQ"#p51963 谢谢！厂家参数在某宝上看到过，不过，厂家的嘛，你懂的😄 刚才抖音上有大佬回复，约-122左右，算是不错了，和k6差不多

@"BG5CJI"#p52001 新款的应该是自动测量的，aprs就是发送这个数据出去

@"tudoubocai"#p52016 然后又是测的打开静噪的电平

@"tudoubocai"#p52016 网上所谓的测灵敏度，都是测的能打开 S1 的最小电平，图一乐写个固件，弄个算法，S1 高于平均背景电平 0.01% 就退出静噪，直接化身毁天灭地神机。

@"BG2ELG"#p52046 这个对于小白来讲，太难了。手里有个艾迪欧uv88，在信号边缘，uv5rhm毫无反应的时候，uv88能达至听清语音，k6这时全是噪声。也就是说，如果测试s1电平的话，k6也和uv88差不多。但实际使用时，抄不清楚语音。

Is the GT12 Pro available for purchase? Has anyone performed sensitivity tests on it?

Is the GT12 Pro available for purchase? Has anyone performed sensitivity tests on it?

I'm looking for a transceiver with high power output that can handle UV (ultra-high frequency) band transmissions. After comparing several options, the Senhaix GT12Pro seems like the best fit. It has Bluetooth connectivity and is also convenient to keep in my car.
However, many people say that the GT12 has a lot of problems, and I'm not sure if the Pro version has improved upon it.
Here's what some ham radio operators have to say about this handheld transceiver.
Thank you!

tudoubocai I've been using the GT12 for daily use and hiking for over a year, and it has mostly worked well. The only issue I had was that the Bluetooth stopped working when I first purchased it, but I exchanged it once, and it's been fine since then. It's essential to bring on hikes during holidays because it has sufficient power and good sound quality and battery life.

BG5ELQ Thank you! I saw the specifications on Taobao, but since it's from the manufacturer, you know how it is.😄
Just saw a reply from a senior user on Douyin, with a value around -122, which is pretty good, and about the same as the K6.

BH9FXF

I bought it, but haven't tried it yet. I'm only interested in the APRS version and hope that the official version will be updated soon.

BG5CJI

BH9FXF Hey, where did you get your GPS information? Was it manually entered, or is it from a built-in module that's measuring in real time?

tudoubocai

BH9FXF So, it seems that the GT12 isn't as bad as people online are saying. The Pro version has also been upgraded, so I think it's worth considering buying one.

BI4NFH

BH9FXF Can this be seen on aprs.tv?

BD8DLV

Given its high power output and differential input capability, perhaps consider the Wouxun UV2Q? (The new QuanSheng machines also seem to have differential input capabilities.)

tudoubocai

BG5CJI The new one should be automatic measurement; APRS sends this data out.

BH9FXF

BG5CJI The GT12 Pro I purchased has built-in satellite positioning, which provides GPS module location data.

BG5ELQ

tudoubocai Then, I measured the noise level while keeping the anti-noise function turned on.

BG2ELG

tudoubocai The "sensitivity testing" mentioned online refers to measuring the minimum level required to open S1. (Image from Tu La)

Write a firmware, create an algorithm: If S1 exceeds the average background level by 0.01%, exit noise cancellation and directly activate the destructive "god-like" function.

tudoubocai

BG5ELQ I previously purchased the 328 and set the noise cancellation to -127. In actual use, it is indeed better than the K6.😁

tudoubocai

BG2ELG This is too difficult for beginners.
I have an iradio UV88. When the signal is weak and the UV5RHM doesn't respond, the UV88 can still pick up voice, but K6 only produces noise. This means that if you test at S1 level, K6 will be similar to the UV88. However, in actual use, it's impossible to clearly hear the voice.

BH9FXF

tudoubocai The pro version has been upgraded, mainly with APRS functionality. I bought it specifically for this feature, but there is still room for further improvements and updates based on individual needs.

tudoubocai

BH9FXF Online, the main complaints are about a high number of bugs and low sensitivity. While a high number of bugs isn't a major issue if it doesn't affect my use, low sensitivity is something I can't tolerate. Ideally, I would want performance at or above k6 level. Of the radios I have, the 328 is the best, followed by the 88s - iradio UV88 - QuanSheng K6 - iradio 2520 - BaoFeng UV5RHM

BH9FXF

tudoubocai I haven't measured it; I don't know either.

BH9FXF

BI4NFH As you can see, if you have this conversation, you should be able to find me here.

BI4NFH

BH9FXF 改天我再试试，不知道咋弄的，我还没报告成功过。

BH3PTS

Syryia With a low noise level setting, the machine can operate in environments with background noise, and the noise level should not be excessively high.

tudoubocai

BH3PTS 普通的灵敏度测试，不光要打开禁噪，还要听清声音。
