Ok The tower is the same, but instead of the vaccum variable that
previously was between the SX1(1400) and the stick, there is now an
entire diplexer as we are adding 1230 to the site.
There was no 1230 transmitter at the time, so that part of it was set
up with an oscillator, and that will be rechecked and everything
retweaked when he comes back in a couple weeks. New transmitter is in
place and happy and when 1400 was working last week we had them both
on with no issues and all the measurements for the 302 came out fine.
