Amateur Radio software for transmission/reception of
JT65 protocol on HF bands 2m - 160m
After installation of version 3.5 check for update files in folder "Updates 3.5" (Link: "Browse All Files"). Update 03 (2016-10-15) is available.
Important note: The JT65 encoding and decoding routines, also used in WSJT, are developed by K1JT, Joe Taylor.
- Fast decoder (receiving interval is variable)
- JT65-Log (default) or HRD, DXKeeper, Log4om, MixW2, Logger32 and WSJT-X.
- Dupe checking and a lot of other infos.
- Acoustic alert
- Adjust time via internet (SNTP)
- CAT with OmniRig, HamLib, HRD or Commander
- Windows with QSO Exchange, Station Infos, Band Statistics and Grids on map
- Callsign band and/or timestamp labels in waterfall display

This is a super program for extra useful features over the JT65-HF version, but it repeatedly misses decodes. Even a single trace that is of the right strength will be missed, but decoded by JT65-HF OK. I am not a programmer, but to me the shorter receive period of 42+ sec is much shorter than JT65-HF, does this have anything to do with the problem. Other than this it is a great program and I congratulate the writer.
Staying in single decoder mode is still a problem. Once the program goes into single mode it never leaves that mode in my installation on Win 7, 64 bit unless the program is closed and reopened. Decoding seems to be excellent for me with the multi-decoder, with more decodes than previous versions side by side comparison. Using the Feb 4 download of the program.
Using last version 0.9.90.0 I'm facing with a problem of decoding... it appears when two overlaped signals is present on waterfall. Single signal of station is decoding correctly almost up to -25db. And blurry waterfall is less informative then classic.
Most of the features of this application are top drawer. The one glaring flaw, as stated in the "Shortcomings" section, is "Poor Decode Result". I've missed many a QSO due to erroneous decode of incoming signals while competing applications (JT65-HF Version 220.127.116.11-Comfort-3.3 ) correctly decode. I have to run a competing application simultaneously to catch any missed decodes. Rather than constantly adding new features, I would suggest concentrating on improving the decode reliability - for me, that would turn my rating of this application from 3 stars to 5 stars!
