    Very good and usefull program, but missing some prefix before callsign such are W0/ W1/ W2/ W3/ W4/ W5/ W6/ W7/ W8/ W9/ ; thank if you can add it soon. 73's F4FPR

    I have been using this software a few days now. I really like how you have the alerts in cw for such things as someone calling cq. I have been using this with my FT-817 and keying the rig with vox. it has worked very well. Thanks.

    Great new features, but I still need support for HRD PTT and JTAlert or I won't use.

    Hello! This software has been my favorite choice for using JT65! The decoding is lightning fast over other software for JT65. I do see some decoder bugs in this latest release where my AMD A8-4500M laptop will not run this software. The last 3 or 4 previous releases will not decode anything on this laptop so no changes there, but this latest release the waterfall runs for one iteration and just stops. Nada, nothing after that. I've played around with the multidecoder and Singledecoder and I get the same results. I've tried both Omnirig and Hamlib and same thing, it just hangs. Using the original JT65 1093 software the laptop works great, also JT9 and WSPR work fine on it, so it is something indigenous with this software. Using it on my old AMD 6000+ dual core desktop this software works, but I still see some odd quirks. I will see someone responding to my CQ, and when I click on their callsign in the decode list, I see the decode bracket move to a blank spot on the waterfall where the software appears to be redirecting my QSO and not to the frequency where the responding operator actually replied. To be safe, I find myself clicking on the reply buttons instead of the decoder window replies to keep these errors from happening. Also, I still see missing decodes. I had set the multidecoder to 20Hz and there will be (7) QSO's in progress, but the decoder only decodes (1) QSO in multidecoder. Changing the multidecoder to 50Hz I get better results. While my desktop is about 7 years old, my laptop is 1 year old, I expected more compatibility issues with my desktop, but it is the other way around. If I could ask for any changes, I would suggest a line showing the spectrum peaks like found on the WSPR software has with that squiggly line at the base of the waterfall. That way us users that have an adjustable IF bandwidth for "eliminating" QRM in the passband would have access to a very quick responding visual indicator showing us where our filter is doing it's magic and we can more accurately adjust it to best effect with or without any band activity as the noise reducing algorithm used on the waterfall display works almost too good! I also would find quite choice if the JT9/JT15 protocol could be also added to this application in future builds! I can't wait to find an excuse to uninstall the older JT9 software that is so much of an annoyance to use! Thanks again! AD0AR- In God we trust, all others we monitor. ;o) UPDATE as of March 19, 2014: I can now use the 20Hz decoder setting with the .9.77.0 release, but it still will not run at all on my A8-4500M based laptop. The waterfall will run for exactly one minute and then the software freezes. This is not radio biased either. It does it on both my 7600 and my 7000. I even disconnected the radios to see it run using the internal mic on the laptop and still, it locks up after one iteration of the waterfall. Program can then only be stopped though task manager (CTRL+ALT+DEL). I have used three other and much older/inferior laptops with this software without a hitch. I even tried a OS reload on the A8 laptop with the same NO-GO result on Windows 7. Also new in this revision is that the waterfall has even less noise in it. When using with my Icom radios that have adjustable IF bandwidth, I cannot tell at all now how large my receive window is and how much of the bandwidth I am blocking without actually audibly listening for blocking of the wanted signals and this leads to missed decodes. Could you add spectral baseline at the bottom of the waterfall? It would help us immensely to see filter action in the waterfall in real time! Also adding JT9 protocol with the advanced logging feature set found in this software would make it indispensable! Thank you HB9HQX for making this software for what it is!

    Important improvements made! One thing: the version behaves strangely sometimes: it does not always decode at all...ruining my qsos sometimes. Some strange status info bug somewhere telling not to decode? Is this is known problem? Windows 7 is the OS.
