Using MMTTY version 1.68 and have downloaded the EXTFSK64 driver and extracted the files into the MMTTY directory.

I have gone through your recent video on single cable MMTTY but can only get the radio to key, no diddle though and that is the problem I have.

Thanks for all the video’s, they have been great… I’m stuck though on getting the IC-7610 to transmit on MMTTY. There is also a quick look at DM780, WSJT-X and JT Alert. I go through the Icom 7610 menu and then the HRD connect screen. UPDATE : See Icom 7610 Virtual Serial (COM) Ports Explained Icom 7610 HRD DM780 WSJT-X and JT Alert Using the first one listed works as it has to correspond with the USB SEND/Keying in the 7610 menu. I believe the first one that shows up in the list under Device Manager>Ports (COM & LPT) is the USB A, and the second listed will be USB B. This is not necessary, but you’ll have to be careful when choosing the COM port in the software. I assigned port numbers that are familiar to me. When I connected the Icom 7610 and looked in Windows 10 Device Manger I saw there are two COM ports now, when I expected just one like the Icom 7300. Once you have it working, use the HRD Preset to connect. There are a couple of ways to fix this, one is in the radio menu and the other, just enter 98 in HRD when the connect screen comes up. When trying to make my first test transmission DM780 alerted me there wasn’t a TX button in the DM780 rig control. (UPDATE: The IC-7610 is now listed in HRD.) I haven’t explored it fully, but the rig control is working. Using the IC-7700 as the rig in HRD’s drop down list, works good. It wasn’t hard to configure HRD to work with the IC-7610, even though the rig is not listed in the software. I’ll post some screens shots here because a picture is worth a thousand words. Many items in the Connectors menu are similar though. There are just more sub menu’s than the 7300. The 7610’s menu is a little daunting at first, but it is similar to the Icom 7300. Plug the cable into the USB 2.0 port, not the USB 3.0 (blue) port on the back of the rig. When attaching the USB cable have the software driver installed first.

I’m using two cables as with the 7300 while operating, but I’ll show using just the USB cable and that works FB as well. This time when connecting you’ll have two virtual COM ports, A and B. I suggest doing that first, before connecting the USB cable. I decided to download the driver and reinstall it. Even though the IC-7300 and the IC-7610 uses the same downloaded driver from Icom, it is an updated driver with a driver date of 5.
