The version 1.0.7 software is superb. But...
The three add-ons that you (IZ4CZL) supply (JT-Alert-1.4.1+; JT-Import1.0.0+; JT-Macros1.0.2) are the greatest software improvements known to man. JT-Alert is so great it makes me weep. After using v1.0.7 for several months I had a mental list of "it should do this" and "it'd be great if it did this". And JT-Alert does every single one of those things.
To anybody using JT65 on HF, I seriously urge (in fact, I demand) that you try out JT-Alert. I know you will like it.

http://iz4czl.ucoz.com/index/0-28JT-Alert docks to the bottom of the v1.0.7 window. Every minute it puts up a horizontal list of all incoming call signs for that minute. If they are a CQ, it puts them in green and the PC talks to you. If they are addressed to your callsign, it puts them in red and the PC talks to you. If you've QSO'd them before, it puts them in grey and adds the text " - B4" so you know. You can select a list of states that you're looking for and if a callsign from one of those states comes in on a CQ it puts it in yellow and the PC talks to you. It also gives you an option to "quit TX after current message", so you can fire off your "73" and then take a bio-break without worrying about sending your "73" over and over. Yes, it's all that and a bag of chips too.
JT-Import lets you import an ADIF into a tracking database that JT-Alert uses to "know" whether you've QSO'd an incoming call. A separate (free) database associates all US call signs with states. It takes 10 minutes to set up but after that it's pure butter, baby.
JT-Macros adds a bunch of macros that you can then send over to v1.0.7 (personally I don't use it but I can see how it's cool). Works like the built in macros, but there are lots more.
So IZ4CZL, thank you for making my life better and my hobby more fun. You're the tops.
