Forum: GNU Radio gnuradio-companion & hamlib bodging

Hi,

In gnuradio-companion,  I'm tring to control my KX3 transceiver using
hamlib's rigctl utility.

I've bodged a call to:
    float(pexpect.run("rigctl -m 229 -r /dev/ttyUSB0 -s 38400 f"))
in a variable block's value, and then used that to set the wxgui
waterfall sink's baseband frequency, which works but i'm trying to
figure out 2 more things.

1) Can i do something similar to set the KX3's vfo frequency? a similar
command to rigctl can be used if i can bodge the call  into Freq Set
Varname somehow.

2) Somehow i need to accommodate physical knobulation of the VFO on the
radio, and keep the waterfall scale in sinc with the radio, i.e. by
polling the same command i've used above.  Is there any chance i can do
that via similar bodging in gnuradio-companion, or, am I actually going
to have to write actually write some code?

Cheers,

Darren, G0HWW

Never mind.  I've bodged it directly in the generated python.

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

Hi Darren,

Great you got things working for you!

The wx stuff is all done in Python, so I'm surprised to hear of a
memory leak there. Can you confirm how big a leak it is?
