Hi again,
I've got my gnuradio 'pan-adapter' for my KX3 transceiver pretty much
working now: http://www.g0hww.net/2012/10/gnuradio-hamlib-and-kx3.html
but there seems to be a memory leak occurring when I call
self.wxgui_waterfallsink2_0.set_baseband_freq(self.rig_freq)
to update the waterfall's baseband centre frequency with the result of
polling the transceiver (using pexpect with hamlib's rigctl).
To be clear, the leak only occurs when set_baseband_freq() is called. if
that line is commented out, there is no leak.
Is this a known issue?
Cheers,
Darren
