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?

tudoubocai

BH3PTS A standard sensitivity test requires not only turning on noise cancellation but also clearly hearing the sound.

BH3PTS

tudoubocai According to scientific testing methods, a high level of sensitivity requires a signal-to-noise ratio of at least 12 dB. The concept of "hearing clearly" varies from person to person.

BH9FXF I'll try again another time, but I don't know how to do it. I haven't been successful in reporting before.

BH9FXF

BI4NFH Is there a gateway nearby? Also, have you updated your hardware?

BI4NFH

BH9FXF There should be a gateway nearby, with an IP address of 144.640. My version is 2.0.4.

BI4NFH

BH9FXF Is it possible to directly press PTT on frequency 144.640?

BD3RJJ

I have the GT12 Pro, and I even find it to be a bit too sensitive. I often see it flashing on its own, while the K6 and RTX 8600 Pro don't react at all. At the time, I thought there might be a bug, but then I realized that there was actually someone talking in the background, and the signal was just too weak for the other two devices to pick up.

BH9FXF

BI4NFH
First, you need to update the version, and then configure it within that version.

BH9FXF

BI4NFH Once the update is complete, set the frequency to 144640, open the APRS settings, and enable APRS; GPS should also be enabled. Configure the beacon with your call sign, SSID, coordinate source, and other radio symbols. Then exit and press the custom key to configure one of the unused keys as "BEACN TX". Now, hold down that configured key to transmit. Make sure you can connect to the APRS gateway. After transmitting, check the map to see if it's working.

BI4NFH

BH9FXF Okay, I'll try it.

BI4NFH

BH9FXF Could you add me on WeChat? I would appreciate your guidance.

BH9FXF

BI4NFH You search for me: sa3u3n5

BI4NFH

BH9FXF Okay, added it.
