I have to admit to being more than a little disappointed with the tone of elements within this thread so I'll apologise in advance if what I have to say offends anyone.
The last two years have seen an unprecedented level of activity from the ISS and their support teams with operations in all modes currently available. Personally I have found it most interesting and enjoyable.
Whilst I can understand the frustration of those wishing to make a voice QSO with one of the crew (or visitors) we should remember that despite it being their choice they are doing a job few of us would match up to. Whether and how they choose to operate in their 'spare' time is a matter for them, it does not deserve our criticism.
Enjoy whatever is on offer and remember that having a voice contact with them is a privilege not a right.
