MCU 2.68 / DSP 1.48
- AM MODE ADDED: AM mode is now available on the KX2. (AM mode can be removed from the MODE switch rotation by setting MENU: AM MODE to OFF.) AM Receive: AM mode can provide a “warmer” sound when used to copy shortwave broadcast stations, and VFO tuning is less critical than when using SSB modes to copy AM. MENU: VFO CRS provides coarse-tuning selections of 1, 5, 9 and 10 kHz for AM mode. AM Transmit: AM is far less power-efficient than SSB, so SSB is preferred for most communication purposes. However, AM is in use on the ham bands. A good place to look for AM signals is around 3.870 MHz at night. Note: Speech compression should in general be turned off when transmitting in AM mode (set MENU: TX CMP to 0).
