KX3 (ser. no. 08146) works OK on external power, but recently I am experiencing problem using it on internal rechargeable cells.
The AA cells are relatively new Varta Professional No. 5706, 2700 mAh NiMH. They have been charged with a techno-line BC-1000. Measured capacity via an automatic discharge/recharge cycle is according to spec. I have attached a 50 Ohm dummy-load to the KX3. When turned on, it indicates BT 9,7V. BAT MIN is set to 8,2V. When I press ATU TUNE, it turn itself off immediately. With TUN PWR set to 0,1W it works OK when pressing TUNE, but BT drops to 7,6V. If TUN PWR is set to 1W, it switches off when TUNE is pressed. Strange that the voltage drops so much, even if the charger indicated normal cell capacity when automatically discharging them. Any ideas?
