I have found a Yaesu FT1000MP MK5 at a good price, and am wondering about the reliability of this model. Are there any common problems that show up with age? Is $1095 plus shipping a pretty good price for this model with stock filters? Also, will the FH-2 keypad, used with current Yaesus, work on the MK5 also, in place of the FH-1. 73 John AF5CC
