last hours .. but I agree.

This is all I need to know. I have already changed frequency to
accommodate others, I am only trying to find a new frequency which works
for all.

As 6500 is being already used, and has been tuned up I want to use the
same.

ATCA has 6500 set into v156f1_new. This still misses the birdies.

Mopra has 6500 in v156f1_Mp.com (and could be changed in the .SCH more
simply with global 1freq 6500 & glob 2freq 6500).

Parkes Ceduna and Hobart set the frequency by hand, so if you'd set the
LO's appropriately.

  Sorry for these late changes, mi culpa - pero no me faulta.
