Not exactly Brek, as long as the position of the two stations, which are 
in contact with each other, does not vary in the time, you don't have to 
worry about Doppler effect, also if you are trying to get in touch in 
SSB mode in the 13cm  band, you rather have a precise frequency 
reference and actually the other site should have too to find each other,
and where the Doppler  would effect your communication a special 
combination of hardware-software could provide a compensation.
