Understanding Transmit (TX) Focus

micro2R allows changing transmit focus several ways. The R1/R2 lights indicate which radio will transmit in
response to a PTT signal.
Manual TX focus mode
In manual mode, focus (selecting which radio will
transmit) is fully under operator control - the
computer CAN NOT change focus. The operator
can select the active radio (change focus) by taping
the TX R1/R2 button. If micro2R is in AUTO mode,
pressing the TX R1/R2 button will cancel AUTO
mode and at the same time move TX focus to the
selected radio.
In manual mode, micro2R will redirect all CW, FSK,
PTT, WinKey and DVK signals to the "active" radio
(the radio with transmit focus) even when the signal
was assigned to the other radio.
AUTO TX focus mode
In AUTO mode, focus (transmitter selection) is controlled by the logging program. AUTO mode is selected
by a long press (more than 0.5s) of the TX R1/R2 button. AUTO mode is indicated by AUTO light. The
software can control TX focus in several ways (Parallel port [LPT] signals, a virtual COM port signal, or by
using the microHAM SO2R Control Protocol) depending on the TX focus configuration on the SO2R tab.
