[digitalradio] ROS operating frequencies on 20m

2010-03-04 Thread g4ilo
Can anything be done to get the recommended frequencies for ROS on 20m shifted 
out of the 14.101 - 14.109 range that already has established users of other 
modes? On my band plan, 14.101 and up is designated for All modes which goes 
right the way up to 14.350 so there is no reason for digital modes to pile on 
top of each other.

It makes no sense whatever for two modes that can both be used to make weak 
signal contacts - ROS and Olivia - to use the same frequencies, when neither 
users can copy the others' transmissions, possibly not even see the other mode 
activity on the waterfall if it is weak, and certainly not call QRL? in a way 
that could be understood by the other mode user.

Julian,

In the US, the RTTY/data segment of 20m stops at 14.150.

73 - Skip KH6TY

The current UK band plans can be found at

There's an online version and an Excel version that you can download.
