[NCARC] 145.115 back off the air for now

[Steve Henry]

Hi again-

We kept the repeater up and running yesterday based on the need to do
interference testing.  I've gone ahead and shut it back off so that we don't
create any harmful interference.

Meanwhile, George (AB0SF) is moving forward with building the output
isolator and filter assembly.  He also noted that one of the 3rd order IMD
frequencies from our quick calculation yesterday (2 * fx2 - 145.115 =
160.263   fx2 = 152.689 MHz) could match the output broadcast frequency from
a paging transmitter that is nearly continuously keyed at 152.680 MHz.  This
paging transmitter may be on our same antenna tower but this isn't certain.

Sincerely and '73
