Series of 'CQ NPARC NET' for a few minutes Look around a bit before you assume the net is not there. In any event, with the longer days, there will still be some DX signals coming in from the west, so we may have to locate plus or minus QRM. (Note: most RTTY software mentioned below uses AFSK by default.) LSB, using two audio tones generated by your computer, and is the more common and less complicated, but some say less desirable, method of transmitting RTTY), your readout should be somewhat higher, perhaps around 14087, depending on what audio tones your RTTY software is set to. This means if you are running FSK (frequency shift keying) your readout should be close to 14085.įor AFSK (audio frequency shift keying, which is actually When we operate RTTY twe have mostly been on 20 PSK31 and Feld Hell we have worked on 10 meters at aboutĬonvention, PSK31 and Feld Hell uses USB on all bands. Setup for the net, given the dramatic change in band conditions. As of February 2013, we are still experimenting on the best Anyone interested in joining the net should be in touch While David Bean KC2WUF has been servering as net control over Dave Barr K2YG has been in organizing the net Most recently we've been working primarily with The net description: This net is for anyone who wants to experiment with various digital modes including RTTY, PSK-31, Available slides are linked below:ĭigital modes, members have reactivated the digital net. (February 13), PSK (March 12), Hellschrieber (April 9) and Presented so far are: RTTY (January 9), Packet Communications I have to also working on both WSJT-X and WSJT (10.0) which I use mainly for meteor scatter.A series of talks are being given at regular NPARC meetings. I found that on DATA mode the FT-991 brings in some narrow audio filters on both RX (narrower audio spectrum) and TX (which results in the higher freq audio tones on TX being attenuated or completely filtered out). On the FT-991, I set Menu 111, SSB Port Select = USB, Menu 108 (SSB MIC SELECT)=REAR. Similarly changing freq and modes on Fldigi will update your radio. Changing the freq on your rig dial will automatically update the frequency on fldigi. Your rig should now be under CAT control. With this selected and the ‘Device’ specified, click ‘Initialize’. Then when configuring RigCAT, select your FT-991.xml file. I copied this file to my ~/.fldigi folder. So under my Fldigi’s->Configuration->RigCAT, I select ‘/dev/tty.SLAB_USBtoUART’ under ‘Device’ (Baud rate=4800, Stopbits=2) and have enabled ‘CAT command for PTT’.īefore you go configure RigCAT though, first go download the ‘Rig description file’ for the FT-991 from UART6 – So if things dont want to work as expected, just check this and you may need to change the device name accordingly). (Under some usage scenario, I have seen these being picked up under a different number, e.g. Use the first virtual serial interface ‘/dev/tty.SLAB_USBtoUART’ for CAT control.įor software that does not support CAT control and that relies on the traditional RTS/DSR method for ‘hardware PTT’ control, use ‘/dev/tty.SLAB_USBtoUART2’. Tty.SLAB_USBtoUART and tty.SLAB_USBtoUART2 If you now open a terminal window and do a ‘ls /dev’, you should see: Once you have the driver installed, plug in the USB cable to the FT-991. Thats what you will use un your Configuration->Audio->Devices->PortAudio (both Capture and Playback). If you dont install the above, you will only get the audio device working which OSX will automatically detect. The mandatory part is to first install the USB device drivers from the Silicon Labs’ website. 3.23.07 on MacBook Pro using USB serial cable into the back of the FT-991.
