Refer to your RIGblaster manual to verify which pin to use for PTT.Īlso, make sure the 'Always use RTS instead of sending CAT commands' is checked.

Most RIGblasters are configured for RTS pin, some RIGblasters models allow this pin to be configurable. To set HRD to use the RTS pin, goto Tools->Program Options->COM Port TX.įor most RIGblasters, select RTS pin for TX.This aritcle explains how to configure HRD and DM780 to use this TCP/IP socket, and to use RTS pin for PTT control. HRD has a solution that allows it's component software to share a COM port this is accomplished by having HRD starting a TCP/IP server socket and having the secondary applications (such as DM780) connect to this TCP/IP socket. If you put the radio into transmit mode but this LED does not light, that means HRD is configured incorrectly and is using CAT/CI-V commands instead of RTS pin. Most RIGblasters have an LED that is lit while the RTS pin is active, giving you an indication that the audio is routed from the PC to the Radio. If a CAT/CI-V command is used to put radio into transmit mode, and not the RTS pin, that means the audio from the PC is not being routed to the radio. Microsoft Windows will normally not allow a COM port to be opened more than once.Īnother pitfall is that older HRD software will use CAT/CI-V commands to put the radio into transmit mode and not the RTS pin. A common pitfal among RIGblaster users with HRD is when they attempt to use HRD's radio control software and digital mode software at the same time, and both portions of the software both attempt to use the same COM port. Some RIGblasters also contain a radio control port (often labeled CAT) which is connected to the PC via a COM port. Some RIGblasters (especially those with Microphone ports) use this RTS signal to control which audio signal gets routed to the radio, either the PC or the Microphone. Most RIGblaster models use COM port flow control pins (DTR and/or RTS) to control the PTT of your radio, to put the radio in TX or RX mode. A common issue with RIGblaster customers is attempting to use HRD at same time as Digital Master 780 (DM780).
