特意上网查了一下,cat命令里有个:
read tx metering (undocumented)
data1 data2 data3 data4 command(in hex)
x x x x bd
this command returns one byte (00) when in receive. when in transmit, this command returns two bytes (in bcd format) indicating forward power, vswr, alc, and modulation. (see below)
在控制命令bd下,可以显示2位bcd码数据,应该就是分100级,那就非常细了,可以直接用cat命令显示驻波 功率 alc 调制度。
