[DeWillem]

Hello all maybe someone can HELP me. 
I have a FT-1000MP MV and when i listen on 7 or 14Mhz i have signals from s59 in a few minutes (3min) thesignal and modulation from that station dropped down, when i push my PTT switch of the mic on/off the signal came direct back to 59.I hear that there is a function on the radio to clean the relais. 
Please can someone tell me if this is right. 
Many TNX for HELP all.
