Meteo Fax and RTTY frequencies
Here are some weather fax frequencies classified by region, from various internet sources
PSK63
a super-fast psk mode for rtty contesting
Rtty starter
An alternative to getting started is with rttycontesting which is generally a much slower paced contest when compared to the other modes
Radiomateurs BPSK63 - QPSK63
the new bpsk63 and qpsk63 modes derive from bpsk31/qpsk31 but they are twice faster. the minimum ratio signal-to-noise ratio is about - 7 -8 db. the psk63f is similar to psk63 but with a convolutional encoding
