70cm Frequency Coordination

line of sight coverage to receivers at 20ft elevation

W6YRA/R is a closed repeater, for the UCLA community, that is coordinated with SCRRBA.

There are two other repeaters that share the 448.540/443.540 frequency pair. In an effort to reduce interference we are undertaking a SPLAT! analysis of these three sites.

This is a work in progress!

 

An example execution of the code would be:

splat -t w6yra.qth -t ki6mgn.qth -t n6mqs.qth  -f 448.54 -m 1.333 -L
