Firmware Bug and err key message

DC0ED
Hello,

I build my KX3 kit today, the newest firmware revision is installed and there seem to be a strange firmware bug. The KXPD3 option is not installed (and no other option) and only the antenna is connected to the KX3, nothing else. When I set the MENU:CW KEY 1 to TIP=DASH or TIP=DOT and push the data button the KX3 beginns immidiately to transmit and you can not switch it back to receive, you have to switch the KX3 off. Also the menu layer is directly affected, with this setting the menu ends at LCDTEST in the upward direction and at ATU MD in the downward direction, it is not possible to see any other menu item. When you reach the menu item LCDTEST or ATU MD you can't leave the menu and you can't switch the menu item, the menu simply hangs and you have to switch off the KX3 again.
This behavior completely disappears when I set the MENU:CW KEY 1 to HAND. Very strange

Next problem: Every time when I switch the KX3 on, there is the "err key" message in the display, but nothin but the antenna is connected to the KX3? When there is a short the KX3 will tramsmit the hole time, or I'm wrong?

Many thanks in advance
