Hi Terry,  i went for a drive earlier to day to Goolwa see Vk5ade-15 earlier 
today and i was listening to the 10Mhz frequency while on the road the HF 
packets was certainly longer than the usual 1200 BPS there were 4 different 
stations receiving the signal which was most interesting considering the 
time of day.  I had set the Open Tracker Tracker USB for compressed but 
appears that it has not shortened it.
Maybe it is not that important.
