Full disclosure, I am a Yaesu guy. The only Kenwood I own is the Tri-Band HT. Our Club received this radio from the widow of an SK as a donation. I am the caretaker of the 590 and was tasked with finding a new home for it, but for this little problem... The set up: TS-590SG 32 foot, MFJ telescoping mast with a wire all the way up, with roughly 20 feet of horizontal wire to the Shack, connecting to a 4:1 Balun and plenty of above ground radials. Good QSO's from 6 to 75. Every time I fire up the radio, my last Band worked is displayed. It took a lot of frustration before I could see that when I TX'd, the meter on the radio confirmed I was transmitting, yet the needle on the MFJ watt meter / Dummy Load I later connected, displayed both needles resting on zero. Thinking like a frustrated Windows 95 user, a restart might be in order. After a restart, she actually worked . If I moved from 40 to 20 or any other band, I must shut it down and after a restart on the last known band, it works. I would like to think it's a firmware issue or some other demon and not me a Yaesu guy lost in a sea of Kenwoods.
