Working JT65A can sometimes be very frustrating. Today 10m was open and quite a bit of DX was coming in but the sum total of my afternoon's endeavours was precisely two QSOs.
This mode does eat up time. I called several stations to no avail: either they didn't hear me or replied to someone else. A couple of stations I called faded out in mid-QSO so I never received any rogers. I tried calling CQ and had a couple of replies, but they never came back after I sent their report.
It takes two minutes each time to find out if the other guy can even hear you. So you can spend a lot of time on abortive contacts.
On well, there's always tomorrow!
