PTT Control
Figure 122: PTT Control
Some software utilizes a separate COM port than the CAT to activate PTT. These controls allow the user
to configure this separate port to handle these signals.
Enable PTT:
Used to enable the hardware PTT. This control is unavailable (grayed out) unless a
check mark is placed in at least one of the RTS or DTR boxes (see below).
Port:
The COM port used for the PTT signal.
RTS:
Select this box to use the RTS line to engage PTT.
DTR:
Select this box to use the DTR line to engage PTT.
DigL/U Returns LSB/USB
By default DigiL sends or returns the CAT command FSK-R and DigiU sends or returns the CAT
command FSK. If this check box is checked, they will instead send or return LSB and USB respectively.
The third party digital program you are using will determine which behavior is required.
FlexProfiler Installed
Enables the PowerSDR menu for selection for "Remote Profiles". When this menu option is available,
the user can select console profiles created remotely in FlexProfiler
1
from the local PowerSDR console.
Allow Kenwood AI Command
Enables the Kenwood AI command which causes PowerSDR to broadcast the transmit frequency
(normally VFO A, but VFO B if in Split) changes to the CAT system. Normally, CAT only responds to
polling from the remote program. There are a few programs that expect frequency changes to be
broadcast.
