想打卫星，求各位前辈推荐个带自动多普勒功能的手台，主要是不想在通联时旁边还挂着个手机实时计算并调整手台的收发频率。

VR-N76可以直接手机连接自动多普勒，拿着只管喊就可以了（？

uvk6刷萝狮虎固件，缺点就是存储有限，过境前要手动写当前卫星的频率，还要自己校对时间

威诺N76，刷了OpenGD77的手台也可以。

星历是实时变化的，需要一台设备来处理实时变化的星历。还有一种方案是写三个频率到手台中。进来一个频率，中间一个频率，出去一个频率。这样就无关星历。

威诺N76了解一下 doge.jpg 现在支持选择卫星然后自动多普勒了

N76 + 手机另外：（不搞 SSTV 的话）五信道法真不难，FM 中继器差那点频偏没影响，手机上能算星历的软件基本都有实时多普勒，照着调就行了

@"BH2VSQ"#p83807 首先感谢这位友台，我的意思是不需要手机连对讲机，而是给对讲机写入星历文件后让对讲机自己通过自身的定位信息去解算多普勒频移补偿。

@"BH3IAS"#p83907 只有OpenGD77手台能满足，但是每次使用前都建议更新星历并校时，避免星历不准导致通联失败

I am looking for a handheld radio with automatic Doppler function that can be used to communicate with satellites.

BH3IAS

I want to use a satellite, and I'm looking for recommendations from experienced users for a handheld transceiver with automatic Doppler function. Ideally, I don't want to have to manually calculate and adjust the transceiver's transmit and receive frequencies while using it on 通联 (likely referring to a specific communication system or network).

BH2VSQ

The VR-N76 can directly connect to a mobile device for automatic Doppler, and you simply need to speak (?).

BH3IAS

BH2VSQ First, I would like to thank this friendly vendor. What I mean is that the walkie-talkie does not need to be connected to a mobile phone; instead, after writing the star chart file into the walkie-talkie, it uses its own positioning information to calculate and compensate for the Doppler frequency shift.

BG4QBF

The UVK6 unit can be used to flash the Lion Tiger firmware. However, a drawback is that it has limited storage space. Before crossing, you need to manually enter the current satellite's frequency and also verify the time yourself.

BI3AYR

BG4QBF The K6 has firmware that can be used with Dtrac's automatic Doppler function, but a Bluetooth module is required. This can be an internal or external module.

BA7NCT

The Wino N76 also works with the OpenGD77 radio.

BD8ARF

Celestial navigation charts are constantly changing and require a device to process them in real-time.

Another option is to send three frequencies to the middle station. One frequency goes in, one goes out, and the middle station handles the intermediate frequency. This eliminates the need for star tables.

Currently, it supports selecting a satellite and automatically enabling Doppler processing.

BG2ELG

N76 + mobile phone

Also (if not using SSTV): The five-channel method is actually quite simple. Even a small frequency deviation on the FM repeater won't be an issue, and most smartphone software that can calculate star charts have real-time Doppler functionality; just adjust accordingly.

If you want a more comfortable experience, use the N76.

BH7HQT

BH3IAS Only the OpenGD77 handheld device can meet this requirement, but it is recommended to update the star chart and synchronize it before each use to avoid inaccuracies that could lead to communication failure.

BG2ELG

BH3IAS

The downside of calculating everything manually is that you need to rewrite the latest star chart three times a day (I highly recommend using five channels). After all, the handheld device can only calculate frequencies on its own; you still need a phone to calculate the angle and direction.

BA4TAY

Waiting for detailed user instructions from experts.

BH3IAS

After searching for a while, I finally found a radio that met my requirements from a friend: the Freecom D878UVII. The official firmware versions 3.06 and 3.08N include built-in Doppler functionality, and the corresponding write software also includes tools for downloading and writing satellite orbital data.

BH3HYO

Is the Winno N76 really that powerful?

BI3AYR

BI3AYR The built-in version requires some manual operation, but it's worth it in the long run. The external module occupies K ports, which means that the microphone and speakers on this device cannot be used. You will need to use an external headset or microphone.

BI4MKU

The N76 has such powerful features, but there's absolutely no information about it on the official website.

BA7NNC-JOE

BI4MKU There are many videos on Bilibili, and also on the Weibo account of Wino.

FengziLeo

BI4MKU This could be because the feature was recently released and the website hasn't been updated yet.

BH7GUL

The package is for N76.
