[1000mp] Repair of FT-1000MP MKV

[AD5VJ Bob]

I had a similar situation here whereby the subrx when in rx seems to have too much squelch selected even though I have the sub sql
all the way to the left. 

The subrx comes in and out as though the squelch is being broken by the signals being rx'd, but if its all the way to the left there
shouldn't be any squelch to break at all should there?
