0.About 0.2B

In Version 0.2B, APRS transmission function was added. I don't know much about APRS, and I haven't actually been able to test transmission from the UV-K5 to the APRS receiver.
在0.2B版本中，增加了APRS传输功能。我对 APRS 了解不多，而且我实际上无法测试从 UV-K5 到 APRS 接收器的传输。
I did the test with FT-817 and software called Softmodem.
我用FT-817和名为Softmodem的软件进行了测试。

The AX.25 modem, which is composed of software, requires precise time control, but UV-K5's MCU is not equipped with a crystal, making precise control difficult.
AX.25调制解调器由软件组成，需要精确的时间控制，但UV-K5的MCU没有配备晶振，难以精确控制。
However, transmission and reception was confirmed at about 1200 BPS. Please test to see if it actually works.
然而，传输和接收被确认在大约 1200 bps。请测试一下它是否真的有效。
