thank you everyone for your suggestions.
I followed a couple more passes and it seems that I just don't have sufficient signal level - enough to clearly see and track the signal that would be good enough for the UK funcube signals but not enough for 9k6.
Other than that the decoding software and hs-soundmodem all work well together.
I took a look at the passes I would see and I get only one per day where the highest elevation gets as high as 17 degrees, the remainder are all 12 degrees or less.
I have a dual band vertical mounted at roof top level and I may give that a try but unfortunately it doesn't have a mast head pre-amp but I can put a pre-amp in line near the radio which may help.
too much snow on the ground and on the roof; it will be a couple of months before I can get to any real antenna work.
cheers, Graham ve3gtc

The data is Frequency Shift Keying - FSK - so set the sdr to NFM. 15kHz wide seems reasonable to start with.
You should see bytes decoded in hs_soundmodem. If that is working, but the ground station is not decoding then make sure you have the TCP connection setup correctly.
