I am using N1MM Logger with PowerSDR and have bumped up against a problem (maybe) in the way PowerSDR handles PTT via the serial port used for CAT. I am NOT talking about PTT via CAT command, but rather PTT via the RTS or DTR lines.
I have the following serial port pairs set up in com0com: COM7<==>Com17 COM8<==>COM18 PowerSDR is set up as follows: Setup|CAT Control|CAT Control Enable CAT is checked Port is set to COM18 Baud/Parity/Data/Stop settings are irrelevant. Setup|CAT Control|PTT Control Enable PTT is checked Port is set to COM17 RTS is checked DTR is not checked DSP|Keyer|Connections Primary is set to Radio Secondary is set to CAT PTT Line is set to RTS Key Line is set to DTR N1MM is set to use the RTS line on COM8 for PTT and to use the DTR line for sending CW. If I am in CW mode, N1MM Logger keys the radio & sends CW properly. However, if I am running RTTY or PSK31, N1MM does not key the radio. I am virtually certain that N1MM is toggling the RTS line on COM8, but have no real way of proving it. N1MM allows you to set up a second serial port just for PTT/CW control. If I set the 2nd port to COM7 & tell N1MM to use RTS for PTT control and to use DTR for CW keying, then N1MM keys the radio fine in RTTY & PSK31. My question is: Do the DSP|Keyer|Connections settings apply only if you are in CW mode? The FLEX-5000 manual states, "This is useful as some programs allow both CAT commands and COM port line keying for CW." This says that they will work for CW, but does not say whether they apply to other modes. I wrote a simple utility that allows me to open COM8 and toggle the RTS & DTR lines. If PowerSDR is in CWL or CWU modes, then toggling DTR keys the transmitter. If PowerSDR is in any other mode, then toggling RTS and/or DTR has no effect. Is PowerSDR working as designed, or is it a bug? If a bug, I will enter a Bug Report. If not, I will enter a Feature Request. 73, Ray, K9DUR http://k9dur.info _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kc.flex-radio.com/ Homepage: http://www.flex-radio.com/ Message delivered to arch...@mail-archive.com
