Then it didn't appear the next time I started FLDIGI and FLRIG, but if you continue to mess with it, it does appear and you can connect again. I had to mess with it a few times, turning it on and off, hitting UPDATE, hitting INIT (Initialize) until it finally saw it and connected to the 7300 and did initialize. You need to see the COM3 in the Transceiver setup as you configure it to control the 7300. Now, concerning FLRIG: I think there is a bug that stops it from recognizing the COM3 selection when you start it. This was driving me crazy and I finally saw this error, and it corrected it and I finally had a modulated signal being transmitted! On the 7300, when you select SSB-D (data mode) this makes the 7300 modulated by the signal over the USB cable and not the mic or key, as well as keying the transmission on.

(I didn't have the PLAYBACK set to the USB audio codec, so while I heard the transmitted signal from FLDIGI over my PC speakers, it was not going into the USB cable and modulating the 7300). In FLDIGI you need to set the soundcard for both Capture and Playback to USB audio Codec, which is the connection to the 7300 and not your soundcard in your PC. You need to get that working first before anything happens. If you don't see that, your 7300 is not connected to your PC.

You can check this and see if it is really installed by going to the device manager of your pc, checking under ports, and looking to see if a silicon labs driver is there, assigned probably to COM 3. When you load the driver from ICOM into your PC, it enables communication between the 7300 and your PC over the USB cable, assigning one of the PC ports to it. The 7300 lets you switch to transmit mode and also modulate its transmitted signal either through the mic or the accessory port or the USB port. Thank you guys (all the guys from this group that gave lots of this information in my earlier post) and I hope this makes a complete listing of what you have to do for any new hams (like me) or anyone else that wants to get their 7300 set up for digital mode operation (receive AND send): Before all the settings are listed below, let me give a brief explanation of how this connection works, for anyone interested, especially any new hams, because it's very complicated and not completely self evident from the titles and abbreviations of all the settings.Some of you know this.I didn't! I may be missing a few things here, but this is my dissertation at this time.I hope others will add to it or correct it as needed. On a Win 10 PC 64 bit, with the latest Win 10 update. I finally got FLDIGI working completely, modulating the ICOM 7300 signal and controlling it using a single USB cable with FLRIG.
