Try post 20828:

"Farhan mentioned this during his interview with Tom,?. He felt it was due to the cap C114 around the audio preamp Q16, holding the amp on for a bit when that rig is switched into transmit. I wouldn't be surprised that C110 might also be holding U1 on as well. ?He thought about placing a transistor across the cap to discharge it when going into transmit. Drive the transistor from the xmit?voltage."

I still can't find details of the 'transistor across the cap' mod.
