PTT & ACC TAB
The PTT tab provides independent PTT configurations for each radio.
PTT INPUTS
micro2R has six PTT inputs for each radio:
●
PTT generated by the logging program on the virtual COM port RTS or DTR
●
2
nd
PTT generated by a second application on the virtual COM port RTS or DTR
●
PTT generated on the DTR line of the FSK channel if the PTT box is checked.
●
PTT generated on the DTR line of the 2
nd
FSK channel if the PTT box is checked.
The PTT and FSK channels generate the same Serial PTT input (they are logically in parallel).
●
The foot switch attached to the micro2R rear panel RCA jack.
The foot switch PTT will be applied to the radio with transmit focus.
●
WinKey generated PTT.
Depending on the mode used by the logging program, WinKeyer2 can generate a separate PTT
signals for each radio or a single PTT that can be applied to the radio with transmit focus.
NOTE: when WinKey2 is controlled by a logging program, the program configuration determines
whether WinKey generates one or two PTT signals.
PTT OUTPUT
micro2R has one PTT output for each radio located on pin 2 of the RADIO1 and RADIO2 connectors.
Use WinKey PTT: If unchecked, micro2R ignores the PTT from WinKey2.
Generate PTT Output: When checked, micro2R generates a PTT output in
response to the PTT inputs. When unchecked, micro2R does not generate any
PTT output (e.g., VOX/QSK operation).
PTT lead: Specifies lead-in delay.
With WinKey2, PTT lead is the
time between PTT activation
and the first CW output.
With Serial PTT (PTT, 2
nd
PTT,
FSK and 2nd FSK) and the foot
switch, In VOICE and
FSK/DIGITAL, PA PTT and LNA
PTT lead transceiver PTT (PTT1
or PTT2) by the amount of PTT
lead.
PTT tail: Defines how long PTT
remains closed after the last CW character. PTT tail can be set to a constant value or can vary
between seven (1.00 word space) and ten (2.00 word space) dot lengths proportional to the CW
speed.
