我的710连接n1mm发现可以控制ptt，但是没有办法发射提前录制好的语音。后来把ssb语音来源换成usb线缆之后手咪的mic又用不了了，换成mic，n1mm又没法发话音了。怎么实现既可以用n1mm又可以用手咪呢？向各位请教，谢谢回复

@"BG9JDI"#1477 这个问题是我们两个一起发现的，当时也鼓弄了好久。也欢迎BG9JDI来一起讨论一下这个问题😋

FT710 不知道了，我FT891没有问题

在N1MM里把设备换成101D试试

@"BG4IDK"#p82778 我的现在也没有解决这个问题。。。。。。比赛前倒腾合适、比赛别出问题就行了QAQ

请教710 连接 n1mm 如何控制 ptt

Problem connecting to n1mm with ft710

BI1UIW

When I connected my 710 to n1mm, I found that I could control the PTT (transmit/receive), but I couldn't transmit pre-recorded audio. After changing the SSB audio source to a USB cable, the microphone on the handheld radio also stopped working. When I replaced it with a different microphone, n1mm no longer worked either. How can I use both n1mm and the handheld microphone?
I would like to ask for your advice, thank you for your response.

According to the manual, MIC and USB input are mutually exclusive; only one can be used. I typically leave it on AUTO mode so that the radio decides itself, and use CAT commands to control the radio's transmission instead of physical DTR or RTS signals. This works in most cases, but there have been a few instances where the N1MM software sends data, and then using a handheld microphone results in no response. The reason is unknown; I suspect that the PTT signal is being activated on one of the channels, so the corresponding voice signal needs to be selected. As an aside, the FT710 input audio can only use a sampling rate of 44100 Hz; exceeding this will result in no output.

I wrote a `cat` command.

Automatic source switching: MIC ↔ USB

Use CAT commands to switch audio sources via CQ/Exchange/TNX, etc.

@BG9JDI We both discovered this issue together, and we spent a long time trying to figure it out. We would also welcome BG9JDI to join us in discussing this further.😋

BG9JDI

BG4IDK I still haven't figured out how to solve this problem... All I need is to be prepared for the competition and make sure everything goes smoothly. QAQ

I don't know about FT710, but my FT891 is working fine.

BG9CHE

Try replacing the equipment with the 101D in N1MM.

BI1WRX

Could you please advise on how to control the PTT function when using a 710 connection with an n1mm?
