[600MRG] XSH/15 and XKA Collisions

[Andy - KU4XR]

Greetings all: Been noticing since XSH/15 came on the air that he and XKA being so
close to each other in frequency quite often collide with each other when they TX during
the same period... XKA has a slight upward drift in frequency during the 2 minute cycle,
and the resulting overlap of signal allows only the stronger one to squeak thru. and if
they are close in strength, neither on will decode, but both are clearly there ...
