Hi Peter,
Your preamp is overloading. See this article:

Hi Everyone,
Just set up my station and started to receive all the main satellites, using a Gulf satellite antenna (2M + 70cm) + SSB 70cm Preamp and FT736R
When I transmit on 2M, especially FM, it's as if the preamp is squelching - the receive signal reduces significantly. If I turn the preamp off I don't get the problem, I can continue to hear the received signal.
Any ideas?
