[1000mp] Receiver jamming after TX

[pa5ca at chello.nl]

Dear all,
Hope some can help me out on this one.
During the PACC contest I ran in to the following problem with my FT1000MP Mark V field.
It seem that the receiver gets jammed by is own signal... it takes seccond before the S meter returns to the low value.
Switching between (AGC) auto slow makes no differance however setting AGC to fast or OFF makes the differance... S meter responds reasonbly normal.
So I have the feeling that the receiver is not blocked during own TX. Checked it also with the sub receiver, found same behaviour.

The radio is from 2004 and has not done over time... hi..

Looking forward to a reaction.
