设备TYT-MD-UV380Plus，带GPS，使用APRS功能时发现：信道选择了发射APRS会使发射亚音被禁用，这意味着我无法在中继上使用APRS。问一下各位友台有没有解决办法

@"BG4QBF"#p93490 APRS中继一般没有亚音的，直接发就行

APRS的中继叫“Digi”，而不是用语音中继，所以固件关亚音没有毛病

国内的APRS中继都是144.64MHz单工，不需要亚音八重洲的机子在有亚音的语音中继上发APRS无法打开中继

我还真没注意，我使用中继台一般没发过消息，aprs发送肯定正常，我回头试试，给你建议如果有问题就试试最新版本。还有个事情是aprs使用的是V段，信号效果不太好我都不用了

@"BA7NQ"#p93609 我看威诺还是啥手台可以把aprs设置成尾音，中继通联照样用。opengd77的aprs就是纯aprs,打144640了

@"BG4QBF"#p93626 这个专门设置个aprs尾音，就有点扰民了

@"BA7NQ"#p93609 确实存在使用语音中继的APRS中继，但基本上都是海外的老古董中继台才会用，国内没有它的配套设施。用法就是@"BG4QBF"#p93626 提到的APRS尾音。

OPENGD77 - APRS Transmitter - Low Power Issue - Requesting Assistance

BG4QBF

With the TYT-MD-UV380Plus, which includes GPS and APRS functionality, I've found that when using APRS, selecting a channel for transmitting APRS disables the subcarrier. This means I can't use APRS on my repeater. Does anyone have a solution?

BG4QBF APRS repeaters typically don't require a pre-amble; you can transmit directly.

The APRS repeater is called "Digi", not a voice repeater, so there's nothing wrong with the firmware by Guan Yin.

BA7NQ I see that Winradio or any handheld radio can be configured to have APRS transmit as a tail beep, and I would still use the repeater for full communication. The openGDR77's APRS is purely APRS; it transmits on 144640.

BA7NQ There are indeed APRS repeaters that use voice relay, but these are primarily older repeater sites located overseas. Domestic users do not have the necessary infrastructure to support them. The usage is:BG4QBF The APRS callsign mentioned.

The domestic APRS repeaters are all 144.64 MHz simplex, and do not require sub-audible tones.

The Yaesu equipment cannot open the repeater when using the APRS voice relay.

I hadn't noticed either, I haven't used the repeater much, and APRS transmission seems to be working fine. I'll try it again later and give you some feedback if there are any problems; in that case, try the latest version.
There's also another issue: APRS uses the V-band, and the signal quality isn't very good, so I stopped using it.

BG4QBF Having a dedicated APRS tail end can be quite disruptive.
