[Yaesu] MP problems

[Cecil Acuff]

Hi Folks,

        I'm new around here so go easy if I get outside the lines a bit.

I acquired an early FT-1000MP recently and it has a weird problem with the 
DSP section.  It appears that RF is getting into the DSP and sending it off 
into never never land.  It always occurs after a keydown activity.  It's 
random in nature in that you never know when it's going to happen but out of 
the blue when you unkey the mic you will get blasted with full power white 
noise with the receive audio faintly in the mix.  If you are wearing 
headphones you ditch them in a hurry.  Switching the DSP off puts everything 
back to normal minus the DSP effects.  Switch the DSP back on and it's back 
to full noise.  Only way to reset all things to normal is to power the radio 
off and back on and all is OK until it occurs again.  The radio is mint and 
performs great other than that.  It is being evaluated side by side with an 
FT-1000....of the D series except it does not have all the filters.  The MP 
is loaded with InRad in every position.  I'm trying to find an excuse to 
keep one or the other but I can't say one is any better than the other in 
any of the conditions I have been able to put them in.  May just keep 
both...but would like to solve the DSP problem....

Any ideas?  Seen this before?

Thanks in advance for any help...
