  • fine app for any case. I love to use it for reading the high-speed cw. and it works fine. Even if the Operator gives "with left foot".

  • Got here by the flnet page so this comment is for flnet 7.3.2 Symantic is flagging this as A high-risk incident was detected on ED-3 within the group HSPA on 1/19/2018 10:28:14 AM.

  • It works. Developer is VERY responsive to issues and usually has a bug fix out in no more than 24 hours. The user community is also very knowledgeable and helpful.

  • I have used fl apps briefly. Got ready to upgrade, and downloaded fldigi, flmsg, flrig. I wish that the install notes for Windows specifically mentioned whether these apps install standalone, or if they embed in Windows. Also mention how to upgrade...install upgrade in new diir? Overwrite old dir? I found comments in fldigi_4.0.5_help.pdf, sect 8.2 that might apply as good practice in general, but no clue.

  • We are training and using it with our local ARES group. I can't say it works flawlessly BUT when something does go wrong I also look at the computer for changes that could have been made to make FLDIGI or one of its suites malfunction. I have found that some of the computer maintenance programs are often the culprit deleting some files FLIDGI needs. I also leave a couple older versions on just in case a newer version has a flaw in it and doesn't work. These problems are often addressed by the program developer ( s ) and that is why you will see frequent updates not to mention it is constantly evolving sometimes honoring users request for something. I have been using FLDIGI for several years now and saw it change. For instance they have added fields for field day in the built in logging program. When adding a new version it is very important to check your setting to make sure everything is like the previous program. The auto start up especially if you add a new version like FLamp etc. I developed a problem with rig control nothing changed on FLDIGI so I booted up FLRIG and everything is back in order. The Yahoo group is a good resource for help and there are many YouTube video's that help sometimes better than going to the Yahoo group. Not only is it used for ham radio use but SWL's use it also. A good practice and I do it right down all the version numbers from FLDIGI and it's companion programs and check here frequently for new versions!
