I can attest to that from personal experience.

A couple of friends and I did a two-transmitter FD operation. His rig 
was a Flex-1500, mine was a K3. Both running 5W, on battery power 
(separate batteries), on separate antennas.

We had hoped to be able to operate on the same band on different modes. 
In fact, when I was operating CW low in the band and he was listening on 
SSB higher up the band, he said he could not tell when I was 
transmitting. However, the reverse was definitely *not* the case. 
Whenever he pressed the PTT button on the mike on his Flex-1500, my 
received band noise went up by several S units. I could only hear the 
strongest signals through the noise; everything else was covered up. The 
noise level was high as long as his rig was in transmit, even when he 
was not talking into the mike.
