My favorite operating mode is JT65 on HF these days.
I have been very active on PSK31, 63 and 125 since 2001, but JT65 has taken over for the moment.
I am using the program JT65-HF: http://sourceforge.net/projects/jt65-hf
The program keeps the log in an adif file and the only way to check if You remembered to add a QSO is to open the file manually and check.
I have made a small utility to monitor the log in a window. The program is watching the adif file and it updates the QSO list automatically.
The program got it's own page, click HERE
My station when operating JT65 on HF:
I am working on a HF SDR transceiver - further details will show up here later.
Thats all for now :-)
