same here, plus FO-20, UO-14 and maybe some other I don't remember now...

are you working full duplex? I always found SO-50 very easy to work
(well at least to hear myself back), the 74.4 tone must be sent for
one or two seconds continuously then switch to 67 Hz tone. I work with
handeld homemade dual V/U yagi usually and I noticed that this bird is
particularly sensitive to polarization, so I need to rotate often the
yagi to find the best signal. I didn't try recently anyway, beeing on
other bands :-)

if nothing is wrong with the bird yes, you should at least hear
yourself. Activity was low even in Europe on this bird.
