I live about 15 miles from the N0KTA 146.715
repeater. I like to talk to the 146.700 repeater in
Pratt, KS (about 95 miles).

Problem is that when I transmit on 146.100 for
the Pratt machine, I inadvertantly also key up the
146.715 machine.

At first I suspected my transmitter was off freq so
I tested 3 other repeaters - 145.370 at 1/2 mile
away, 146.895 at 1 mile away and 146.850 at
3 miles away. On all three tests, I could key up
those machines as long as I was +/- LESS than 15
khz from the correct input freq. On all 3 when I
went to the next channel (15 khz spacing) up or
down, I could not key up the machine.

I also did a simplex test with an OP about 1/2 mile
away. I tx'ed DTMF #5 for 30 seconds while he
moved above and below my freq. He reported
he lost my signal as soon as he got more than 10 khz
from me. He also reported that the signal levels at
10 khz were equal between + and - .

All these tests were done with a known good antenna
& new CQ-102 coax. Rig is a 1 year old Kenwood
TM-271A. All tests were done at an indicated 68 w
which is about normal for hi power from this rig.

I'll refrain from using the Pratt repeater until this is
fixed.

My question is this - have I done enough to assume
that the problem is not on my end? Sending in my
rig for service monitor testing would be difficult & a
genuine pain in the neck.
