Re: [Discuss-gnuradio] HF explorer

yes, I see the same thing running against svn head at the time of 
writing - rev 11564.

Just comment out lines 371 and 373 of hfx2.py and all seems to work. 
Guess we lose some functionality but at least it does run up. Suppose we 
should debug that really :-;

I've been having too much fun getting jack audio and griffin powermate 
usb thingy going over IP so I can run the USRP on a more powerful remote 
machine and access it from my laptop via nxclient over LAN. Just about 
works now. What's really cool is it's easy to hack gnu radio companion 
to include a jack audio sink. I have to say I'm impressed by GRC. Jack 
audio does a great job too.
