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).
