Was this useful?

PX3 NOW DISPLAYS VFO B PASSBAND CORRECTLY: The PX3 was showing the wrong VFO B filter bandwidth or passband location when using DATA modes or DUAL RX (dual watch).
DUAL RX DOES NOT FORCE OFS/B KNOB TO BE USED AS VFO B: The operators OFS/B knob assignment is no longer lost when DUAL RX is in effect.
FAST-PLAY DISPLAY ERROR FIXED: With fast-play enabled (1-touch message play using BAND+/- and FREQ ENT.), a band change originating from a PC application no longer flashes “END” on VFO B.
CW SPEED DISPLAY TIME INCREASED WHEN TEXT DECODE IS ON: In CW mode, speed is now displayed for 1.0 sec. In FSK-D and PSK-D modes, it's .5 sec. The time is shorter for DATA modes because character transmission rates are usually faster, and the operator might miss important text due to the speed display.
PA BYPASS METERING FIXED: If the KXPA100 goes to bypass because of an error condition, the KX3 drops to 5 W. The RF meter is now correctly set to low range.
TEXT DECODE LOCKOUT FIX: Adjustment of NR, NB, NTCH, etc. no longer causes loss of CW/DATA text decode on the VFO B display.
HOST COMMANDS “UP”, “DN”, and “DT”: These are now working with the PX3.
