在网上搜到psk的低速率模式:psk10
google翻译后:

psk10模式的目的是保证信号弱的比例通信的信噪比下降到-17.5分贝小于2%的错误。 the speed is 18 wpm. 速度是每分钟字数:18。 this mode is very sensitive to the ionospheric doppler modulation. 这种模式是非常敏感的电离层多普勒调制。

而且有人试验,在80米段强噪声干扰下双方能以1瓦的功率使用长线天线在350英哩远进行通联,psk10模式太强大了啊!

psk10


i had a good test of psk10 last night, poor noisy conditions on 80m.
wb2yds and i worked each other at very low power (down to 1 watt at
times) over a 350 mile path, basic wire antennae. psk10 was more
reliable than ale400 and chip64. ale 400 did ok, but we lost the link
and switched back to psk10.

PSKAM10比PSK10还慢,信噪比到-19.5分贝!
该pskam10模式pskam传播10波特。 the speed is about 6 wpm. 速度是每分钟字数约6。 this mode permits only to chat at slowly speed but down to very weak s/n (-19.5 db)...it can be used in lf transmissions. 该模式只允许进行交谈 , 但是在缓慢的速度下降到非常微弱的s / &ntilde;(-19.5分贝)...它可以在低频传输使用。 the bandwidth is about 40 hz. 带宽大约是40赫兹。

the pskam31 mode is pskam transmitted at 31.25 bauds. the speed is about 20 wpm. 该pskam31模式pskam传输到31.25波特。速度达每分钟约20。 this mode permits to chat down to a weak s/n (-14 db). 这种模式允许聊天到弱的s / &ntilde;(-14分贝)。 the bandwidth is about 110 hz. 带宽大约是110赫兹。

  the interleaved pskam50 mode derives from 在交错pskam50模式来自 psk10 mode for the modulation and for amtor fec for the repetition of the characters (time diversity). psk10 模式的调制和前向纠错amtor为字符(时间多样性)的重复。 the speed is 50 bauds but each character is transmitted twice at an interval of five characters (example: axbycad b…). 速度是50波特 , 但每个字符传输到一个5个字符(例如:axbycad乙...)间隔两次。 the speed is about 31 wpm. 速度是每分钟字数约31。 this mode permits to lower appreciably the number of errors due to hf radio conditions (without transmitting random characters). 这种模式允许降低明显的错误 , 由于一些条件高频无线电(不传输随机字符)。 the bandwidth is about 180 hz. 带宽大约是180赫兹。 the lowest s/n is -11.5 db (for a pc at 166 mhz or higher). 最低的s / n为-11.5分贝(为在166 mhz或更高的pc)。
