PDF attached contains notes about the software and hardware in the title. I may add to this post from time to time, if the need arises, and if so, I’ll upload a new rev if this doc. FYI, pay particular attention to fldigi not finding the correct COM port, and editing the COM port drop list to use it. Also note the use of fldigi SIG display to aid setting a usable input audio level for fldigi. Recall that the fldigi RX audio stream includes the radio volume > (hardware gain) > driver gain; the SIG level will depend on all 3. Also note the V71 normalizing audio levels out of the DIN6 port.

@TheDustyKey Wow! This is a very thorough treatment with graphics, too. This will make it easier for people to go digital with this very popular Kenwood radio.

Hello TheDustyKey,
Your write up put all the many bits of information on this Forum together into one easy to follow instruction and guide. This is from the initial Windows acoustical setup and then to FLDIGI. Thank you.

“In the Communications tab of the Sound dialog, where there might be a choice to let Windows manage sound levels, select “Do Nothing”, if it is available.” added to document, plus minor enhancements.

I was working on a different project, and created this image from the digirig schematic on the web. Thought it might be useful to others.

Hello! I am using Fldigi 4.2.11 AND SOMETHING IS WRONG WITH THIS VERSION!!! I am using it in a Windows 11 operating system and I CAN’T GET THE PTT TO WORK TO SAVE MY LIFE!!! I have a Digirig Moble with the cables supplied by the Digirig folks on a TM-D710G which have the same pinout configuration as the TM-V71A. I have my Digirig Moble with these same cables in a Winlink/VARA FM set up that works great! But Fldigi 4.2.11 is flat on its back. If there is anybody else there having problems with this version of Fldigi 4.2.11, I would like to hear from you! And if you got it too work, please let me know also.

Hello! I don’t know what to say! I downloaded fldigi 4.1.22 and set it up according to your document AND IT WORKED!! Can’t explain it. PTT did its thing and FSQ 6.0 tones went out!! But what is even a BIGGER miracle, I tried the latest Fldigi 4.2.11 AND IT WORKS NOW!! Again I made sure all your settings were like you said and it now works! Amazing!!
Thank you!

Hi Dave,
Sorry for the delay replying…it’s a brutal winter in New England, more like Alaska /grin/ and in addition to temperatures staying below 0C, and frequently hitting -20C overnights, we just finished a (for here) large snowstorm. Lotsa neighbors helping neighbors /grin/. I’ve been meaning to take a look at the doc and see if it needs updating. Glad to hear that it all worked out for you! 73 Rich NE1EE
Hi Rich. Thank you again for your document for the digirig 1.9 and the latest fldigi. If you decided to update your document for Windows 11, I’ll be happy to pass along a few things that I have learned the hard way!! Hi hi!! There are a few little things that are different that might confuse folks.
