Sounds like front-end overload to me. Just my humble opinion.

Hi,
The difference in frequency between the two transmitters is 300
kilohertz. 300 kilohertz is exactly 1/2 of the separation of either
machine; 600 kc.
While there are methods and equipment that can be purchased to make the
two co-exist, my recommendation is to move one of them to another

---Are these standard split repeaters? Assuming so, the 147.225 repeater
(output?) places the input at 147.825
How about clarifying the input freqs for these repeaters?

Nice catch :-)

There are two machines on the same tower on these frequencies with
one antenna about 20 feet directly over the other. Each machine is
putting out about 30 - 50 watts. Each machine plays fine by itself,
but as
Hmmm. Your transmitters are 300 KHz apart. Your duplex split is 600
KHz. Sounds suspicious to me.
My friend KA1OKQ runs a 146.94 and 147.225 on the same tower. No
problems. All MASTR II. But those pairs are enough different from yours
to make all the difference.

Not to mention there are all sorts of odd order mixes with his freqs:
Third Order Results:
147.2250 MHz + 147.2250 MHz - 146.9250 MHz 147.9250 MHz

---you guys considered adding circulators to your transmitters? That would
solve the mixing issues..
